本次分享包括两篇文章
  • 父子关系维护检索实战一 Elasticsearch 5.x 父子关系维护检索实战
  • 父子关系维护检索实战二 Elasticsearch 6.x 父子关系维护检索实战
本文是其中第一篇- Elasticsearch 5.x 父子关系维护检索实战,涵盖以下部分内容:
  1. Elasticsearch 5.x 中父子关系mapping结构设计
  2. Elasticsearch 5.x 中维护父子关系数据
  3. Elasticsearch 5.x 中has_child和has_parent查询的基本用法
  4. Elasticsearch 5.x 中如何在检索中同时返回父子数据
案例说明 以一个体检记录相关的数据来介绍本文涉及的相关功能,体检数据包括客户基本信息basic和客户医疗记录medical、客户体检记录exam、客户体检结果分析记录diagnosis,它们之间的关系图如下:

我们采用Elasticsearch java客户端 bboss-elastic 来实现本文相关功能。 1.准备工作 参考文档《高性能elasticsearch ORM开发库使用介绍》导入和配置bboss客户端 2.定义mapping结构-Elasticsearch 5.x 中父子关系mapping结构设计 Elasticsearch 5.x中一个indice mapping支持多个mapping type,通过在子类型mapping中指定父类型的mapping type名字来设置父子关系,例如: 父类型 "basic": { .... } 子类型: "medical": {        "_parent": { "type": "basic" },      ................. } 新建dsl配置文件-esmapper/Client_Info.xml,定义完整的mapping结构:createClientIndice
<properties>
  
    <!--
   创建客户信息索引索引表
   -->
    <property name="createClientIndice">

这个mapping中定义了4个索引类型:basic,exam,medical,diagnosis,其中basic是其他类型的父类型。 通过bboss客户端创建名称为client_info 的索引:
	public void createClientIndice(){
		//定义客户端实例,加载上面建立的dsl配置文件
		ClientInterface clientUtil = ElasticSearchHelper.getConfigRestClientUtil("esmapper/Client_Info.xml");
		try {
			//client_info存在返回true,不存在返回false
			boolean exist = clientUtil.existIndice("client_info");

			//如果索引表client_info已经存在先删除mapping
			if(exist) {//先删除mapping client_info
				clientUtil.dropIndice("client_info");
			}
		} catch (ElasticSearchException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		//创建mapping client_info
		clientUtil.createIndiceMapping("client_info","createClientIndice");
		String client_info = clientUtil.getIndice("client_info");//获取最新建立的索引表结构client_info
		System.out.println("after createClientIndice clientUtil.getIndice(\"client_info\") response:"+client_info);
	}
3.维护父子关系数据-Elasticsearch 5.x 中维护父子关系数据
  • 定义对象
首先定义四个对象,分别对应mapping中的四个索引类型,篇幅关系只列出主要属性
  • Basic
  • Medical
  • Exam
  • Diagnosis
通过注解@ESId指定基本信息文档_id
public class Basic extends ESBaseData {
    /**
     *  索引_id
     */
    @ESId
    private String party_id;
    private String sex;                     // 性别
    ......
}    
通过注解@ESParentId指定Medical关联的基本信息文档_id,Medical文档_id由ElasticSearch自动生成
public class Medical extends ESBaseData {
    @ESParentId
    private String party_id;          //父id
    private String hos_name_yb;         //就诊医院
    ...
}
通过注解@ESParentId指定Exam关联的基本信息文档_id,Exam文档_id由ElasticSearch自动生成
public class Exam extends ESBaseData {
    @ESParentId
    private String party_id;          //父id
    private String  hospital;           // 就诊医院
    ....
}    
通过注解@ESParentId指定Diagnosis关联的基本信息文档_id,Diagnosis文档_id由ElasticSearch自动生成
public class Diagnosis extends ESBaseData {
    @ESParentId
    private String party_id;          //父id
    private String provider;            //诊断医院
    private String subject;             //科室
    ......
}    
  • 通过api维护测试数据
对象定义好了后,通过bboss客户数据到之前建立好的索引client_info中。
	/**
	 * 录入体检医疗信息
	 */
	public void importClientInfoDataFromBeans()  {
		ClientInterface clientUtil = ElasticSearchHelper.getRestClientUtil();

		//导入基本信息,并且实时刷新,测试需要,实际环境不要带refresh
		List<Basic> basics = buildBasics();
		clientUtil.addDocuments("client_info","basic",basics,"refresh");

		//导入医疗信息,并且实时刷新,测试需要,实际环境不要带refresh
		List<Medical> medicals = buildMedicals();
		clientUtil.addDocuments("client_info","medical",medicals,"refresh");

		//导入体检结果数据,并且实时刷新,测试需要,实际环境不要带refresh
		List<Exam> exams = buildExams();
		clientUtil.addDocuments("client_info","exam",exams,"refresh");

		//导入结果诊断数据,并且实时刷新,测试需要,实际环境不要带refresh
		List<Diagnosis> diagnosiss = buildDiagnosiss();
		clientUtil.addDocuments("client_info","diagnosis",diagnosiss,"refresh");
	}
	//构建基本信息集合
	private List<Basic> buildBasics() {
		List<Basic> basics = new ArrayList<Basic>();
		Basic basic = new Basic();
		basic.setParty_id("1");
		basic.setAge(60);
		basics.add(basic);
		//继续添加其他数据
		return basics;

	}
	//
构建医疗信息集合
	private List<Medical> buildMedicals() {
		List<Medical> medicals = new ArrayList<Medical>();
		Medical medical = new Medical();
		medical.setParty_id("1");//设置父文档id-基本信息文档_id
		medical.setCreated_date(new Date());
		medicals.add(medical);
		//继续添加其他数据
		return medicals;

	}
	//构建体检结果数据集合
	private List<Exam> buildExams() {
		List<Exam> exams = new ArrayList<Exam>();
		Exam exam = new Exam();
		exam.setParty_id("1");//设置父文档id-基本信息文档_id
		exams.add(exam);
		//继续添加其他数据
		return exams;
	}
	//构建结果诊断数据集合
	private List<Diagnosis> buildDiagnosiss() {
		List<Diagnosis> diagnosiss = new ArrayList<Diagnosis>();
		Diagnosis diagnosis = new Diagnosis();
		diagnosis.setParty_id("1");//设置父文档id-基本信息文档_id
		diagnosiss.add(diagnosis);
		//继续添加其他数据
		return diagnosiss;
	}
  • 通过json报文批量导入测试数据
除了通过addDocuments录入数据,还可以通过json报文批量导入数据 在配置文件esmapper/Client_Info.xml增加以下内容:

通过bboss提供的通用api,导入上面定义的数据:
	/**
	 * 通过读取配置文件中的dsl json数据导入医疗数据
	 */
	public void importClientInfoFromJsonData(){
		ClientInterface clientUtil = ElasticSearchHelper.getConfigRestClientUtil("esmapper/Client_Info.xml");

		clientUtil.executeHttp("client_info/basic/_bulk?refresh","bulkImportBasicData",ClientUtil.HTTP_POST);
		clientUtil.executeHttp("client_info/diagnosis/_bulk?refresh","bulkImportDiagnosisData",ClientUtil.HTTP_POST);
		clientUtil.executeHttp("client_info/medical/_bulk?refresh","bulkImportMedicalData",ClientUtil.HTTP_POST);
		clientUtil.executeHttp("client_info/exam/_bulk?refresh","bulkImportExamData",ClientUtil.HTTP_POST);
统计导入的数据
		
		long basiccount = clientUtil.countAll("client_info/basic");
		System.out.println(basiccount);
		long medicalcount = clientUtil.countAll("client_info/medical");
		System.out.println(medicalcount);

		System.out.println(examcount);
		long diagnosiscount = clientUtil.countAll("client_info/diagnosis");
		System.out.println(diagnosiscount);
	}
4.父子关系查询-Elasticsearch 5.x 中has_child和has_parent查询的基本用法​
  • 根据父查子-通过客户名称信息查询客户端体检结果
在配置文件esmapper/Client_Info.xml增加dsl语句:queryExamSearchByClientName
   <!--根据客户名称查询客户体检报告-->
    <property name="queryExamSearchByClientName">
        <![CDATA[
            {
              "query": {
                ## 最多返回size变量对应的记录条数
                "size":#[size],
                "has_parent": {
                  "type": "basic",
                  "query": {
                    "match": {
                      "client_name": #[clientName] ## 通过变量clientName设置客户名称
                    }
                  }
                }
              }
            }
        ]]>
    </property>
 执行查询,通过bboss的searchList 方法获取符合条件的体检报告以及总记录数据,返回size对应的1000条数据
	/**
	 * 根据客户名称查询客户体检报告
	 */
	public void queryExamSearchByClientName(){
		ClientInterface clientUtil = ElasticSearchHelper.getConfigRestClientUtil("esmapper/Client_info.xml");
		Map<String,Object> params = new HashMap<String,Object>();
		params.put("clientName","张三");
		params.put("size",1000);
		ESDatas<Exam> exams = clientUtil.searchList("client_info/exam/_search","queryExamSearchByClientName",params,Exam.class);
		List<Exam> examList = exams.getDatas();//获取符合条件的体检数据
		long totalSize = exams.getTotalSize();//符合条件的总记录数据
	}
 
  • 根据子查父数据-通过医疗信息编码查找客户基本数据
在配置文件esmapper/Client_Info.xml增加查询dsl语句:queryClientInfoByMedicalName
    <!--通过医疗信息编码查找客户基本数据-->
    <property name="queryClientInfoByMedicalName">
        <![CDATA[
            {
              "query": {
                ## 最多返回size变量对应的记录条数
                "size":#[size],
                "has_child": {
                  "type":       "medical",
                  "score_mode": "max",
                  "query": {
                    "match": {
                      "medical_code": #[medicalCode] ## 通过变量medicalCode设置医疗编码
                    }
                  }
                }
              }
            }
        ]]>
    </property>

		long totalSize = bascis.getTotalSize();
	}
5.同时返回父子数据-Elasticsearch 5.x 中如何在检索中同时返回父子数据 这一节中我们介绍同时返回父子数据的玩法 :inner_hits的妙用
  • 根据父条件查询所有子数据集合并返回父数据,根据客户名称查询所有体检数据,同时返回客户信息
在配置文件esmapper/Client_Info.xml增加检索dsl-queryDiagnosisByClientName
    <!--根据客户名称获取客户体检诊断数据,并返回客户信息-->
    <property name="queryDiagnosisByClientName">
        <![CDATA[
            {
              "query": {
                ## 最多返回size变量对应的记录条数
                "size":#[size],
                "has_parent": {
                  "type": "basic",
                  "query": {
                    "match": {
                      "client_name": #[clientName] ## 通过变量clientName设置客户名称
                    }
                  },
                  "inner_hits": {}  ## 通过变量inner_hits表示要返回对应的客户信息
                }
              }
            }
        ]]>
    </property>
执行检索并遍历结果
	/**
	 * 根据客户名称获取客户体检诊断数据,并返回客户数据
	 */
	public void queryDiagnosisByClientName(){

		ClientInterface clientUtil = ElasticSearchHelper.getConfigRestClientUtil("esmapper/Client_info.xml");
		Map<String,Object> params = new HashMap<String,Object>();
		params.put("clientName","张三");
		params.put("size",1000);

		try {
			ESInnerHitSerialThreadLocal.setESInnerTypeReferences(Basic.class);//指定inner查询结果对应的客户基本信息类型,Basic只有一个文档类型,索引不需要显示指定basic对应的mapping type名称
			ESDatas<Diagnosis> diagnosiss = clientUtil.searchList("client_info/diagnosis/_search",
					"queryDiagnosisByClientName",params,Diagnosis.class);
			List<Diagnosis> diagnosisList = diagnosiss.getDatas();//获取符合条件的体检报告数据
			long totalSize = diagnosiss.getTotalSize();
			//遍历诊断报告信息,并查看报告对应的客户基本信息
			for(int i = 0;  diagnosisList != null && i < diagnosisList.size(); i ++) {
				Diagnosis diagnosis = diagnosisList.get(i);
				List<Basic> basics = ResultUtil.getInnerHits(diagnosis.getInnerHits(), "basic");
				if(basics != null) {
					System.out.println(basics.size());
				}
			}
		}
		finally{
			ESInnerHitSerialThreadLocal.clean();//清空inner查询结果对应的客户基本信息类型
		}
	}
  •  根据子条件查询父数据并返回符合条件的父的子数据集合,查询客户信息,同时返回客户对应的所有体检报告、医疗记录、诊断记录
在配置文件esmapper/Client_Info.xml增加检索dsl-queryClientAndAllSons
    <!--查询客户信息,同时返回客户对应的所有体检报告、医疗记录、诊断记录-->
    <property name="queryClientAndAllSons">

本次分享包括两篇文章
  • 父子关系维护检索实战一 Elasticsearch 5.x 父子关系维护检索实战
  • 父子关系维护检索实战二 Elasticsearch 6.x 父子关系维护检索实战
本文是其中第一篇- Elasticsearch 5.x 父子关系维护检索实战,涵盖以下部分内容:
  1. Elasticsearch 5.x 中父子关系mapping结构设计
  2. Elasticsearch 5.x 中维护父子关系数据
  3. Elasticsearch 5.x 中has_child和has_parent查询的基本用法
  4. Elasticsearch 5.x 中如何在检索中同时返回父子数据
案例说明 以一个体检记录相关的数据来介绍本文涉及的相关功能,体检数据包括客户基本信息basic和客户医疗记录medical、客户体检记录exam、客户体检结果分析记录diagnosis,它们之间的关系图如下:
parent.png
我们采用Elasticsearch java客户端 bboss-elastic 来实现本文相关功能。 1.准备工作 参考文档《高性能elasticsearch ORM开发库使用介绍》导入和配置bboss客户端 2.定义mapping结构-Elasticsearch 5.x 中父子关系mapping结构设计 Elasticsearch 5.x中一个indice mapping支持多个mapping type,通过在子类型mapping中指定父类型的mapping type名字来设置父子关系,例如: 父类型 "basic": { .... } 子类型: "medical": {        "_parent": { "type": "basic" },      ................. } 新建dsl配置文件-esmapper/Client_Info.xml,定义完整的mapping结构:createClientIndice

这个mapping中定义了4个索引类型:basic,exam,medical,diagnosis,其中basic是其他类型的父类型。 通过bboss客户端创建名称为client_info 的索引:
	public void createClientIndice(){
		//定义客户端实例,加载上面建立的dsl配置文件
		ClientInterface clientUtil = ElasticSearchHelper.getConfigRestClientUtil("esmapper/Client_Info.xml");
		try {
			//client_info存在返回true,不存在返回false
			boolean exist = clientUtil.existIndice("client_info");

			//如果索引表client_info已经存在先删除mapping
			if(exist) {//先删除mapping client_info
				clientUtil.dropIndice("client_info");
			}
		} catch (ElasticSearchException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		//创建mapping client_info
		clientUtil.createIndiceMapping("client_info","createClientIndice");
		String client_info = clientUtil.getIndice("client_info");//获取最新建立的索引表结构client_info
		System.out.println("after createClientIndice clientUtil.getIndice(\"client_info\") response:"+client_info);
	}
3.维护父子关系数据-Elasticsearch 5.x 中维护父子关系数据
  • 定义对象
首先定义四个对象,分别对应mapping中的四个索引类型,篇幅关系只列出主要属性
  • Basic
  • Medical
  • Exam
  • Diagnosis
通过注解@ESId指定基本信息文档_id
public class Basic extends ESBaseData {
    /**
     *  索引_id
     */
    @ESId
    private String party_id;
    private String sex;                     // 性别
    ......
}    
通过注解@ESParentId指定Medical关联的基本信息文档_id,Medical文档_id由ElasticSearch自动生成
public class Medical extends ESBaseData {
    @ESParentId
    private String party_id;          //父id
    private String hos_name_yb;         //就诊医院
    ...
}
通过注解@ESParentId指定Exam关联的基本信息文档_id,Exam文档_id由ElasticSearch自动生成
public class Exam extends ESBaseData {
    @ESParentId
    private String party_id;          //父id
    private String  hospital;           // 就诊医院
    ....
}    
通过注解@ESParentId指定Diagnosis关联的基本信息文档_id,Diagnosis文档_id由ElasticSearch自动生成
public class Diagnosis extends ESBaseData {
    @ESParentId

  • 通过api维护测试数据
对象定义好了后,通过bboss客户数据到之前建立好的索引client_info中。
	/**
	 * 录入体检医疗信息
	 */
	public void importClientInfoDataFromBeans()  {
		ClientInterface clientUtil = ElasticSearchHelper.getRestClientUtil();

		//导入基本信息,并且实时刷新,测试需要,实际环境不要带refresh
		List<Basic> basics = buildBasics();
		clientUtil.addDocuments("client_info","basic",basics,"refresh");

		//导入医疗信息,并且实时刷新,测试需要,实际环境不要带refresh
		List<Medical> medicals = buildMedicals();
		clientUtil.addDocuments("client_info","medical",medicals,"refresh");

		//导入体检结果数据,并且实时刷新,测试需要,实际环境不要带refresh
		List<Exam> exams = buildExams();
		clientUtil.addDocuments("client_info","exam",exams,"refresh");

		//导入结果诊断数据,并且实时刷新,测试需要,实际环境不要带refresh
		List<Diagnosis> diagnosiss = buildDiagnosiss();
		clientUtil.addDocuments("client_info","diagnosis",diagnosiss,"refresh");
	}
	//构建基本信息集合
	private List<Basic> buildBasics() {
		List<Basic> basics = new ArrayList<Basic>();
		Basic basic = new Basic();
		basic.setParty_id("1");
		basic.setAge(60);
		basics.add(basic);
		//继续添加其他数据
		return basics;

	}
	//
构建医疗信息集合
	private List<Medical> buildMedicals() {
		List<Medical> medicals = new ArrayList<Medical>();
		Medical medical = new Medical();
		medical.setParty_id("1");//设置父文档id-基本信息文档_id
		medical.setCreated_date(new Date());
		medicals.add(medical);
		//继续添加其他数据
		return medicals;

	}
	//构建体检结果数据集合
	private List<Exam> buildExams() {
		List<Exam> exams = new ArrayList<Exam>();
		Exam exam = new Exam();
		exam.setParty_id("1");//设置父文档id-基本信息文档_id
		exams.add(exam);
		//继续添加其他数据
		return exams;
	}
	//构建结果诊断数据集合
	private List<Diagnosis> buildDiagnosiss() {
		List<Diagnosis> diagnosiss = new ArrayList<Diagnosis>();
		Diagnosis diagnosis = new Diagnosis();
		diagnosis.setParty_id("1");//设置父文档id-基本信息文档_id
		diagnosiss.add(diagnosis);
		//继续添加其他数据
		return diagnosiss;
	}
  • 通过json报文批量导入测试数据
除了通过addDocuments录入数据,还可以通过json报文批量导入数据 在配置文件esmapper/Client_Info.xml增加以下内容:

通过bboss提供的通用api,导入上面定义的数据:
	/**
	 * 通过读取配置文件中的dsl json数据导入医疗数据
	 */
	public void importClientInfoFromJsonData(){
		ClientInterface clientUtil = ElasticSearchHelper.getConfigRestClientUtil("esmapper/Client_Info.xml");

		clientUtil.executeHttp("client_info/basic/_bulk?refresh","bulkImportBasicData",ClientUtil.HTTP_POST);
		clientUtil.executeHttp("client_info/diagnosis/_bulk?refresh","bulkImportDiagnosisData",ClientUtil.HTTP_POST);
		clientUtil.executeHttp("client_info/medical/_bulk?refresh","bulkImportMedicalData",ClientUtil.HTTP_POST);
		clientUtil.executeHttp("client_info/exam/_bulk?refresh","bulkImportExamData",ClientUtil.HTTP_POST);
统计导入的数据
		
		long basiccount = clientUtil.countAll("client_info/basic");
		System.out.println(basiccount);
		long medicalcount = clientUtil.countAll("client_info/medical");
		System.out.println(medicalcount);

		System.out.println(examcount);
		long diagnosiscount = clientUtil.countAll("client_info/diagnosis");
		System.out.println(diagnosiscount);
	}
4.父子关系查询-Elasticsearch 5.x 中has_child和has_parent查询的基本用法​
  • 根据父查子-通过客户名称信息查询客户端体检结果
在配置文件esmapper/Client_Info.xml增加dsl语句:queryExamSearchByClientName
   <!--根据客户名称查询客户体检报告-->
    <property name="queryExamSearchByClientName">
        <![CDATA[
            {
              "query": {
                ## 最多返回size变量对应的记录条数
                "size":#[size],
                "has_parent": {
                  "type": "basic",
                  "query": {
                    "match": {
                      "client_name": #[clientName] ## 通过变量clientName设置客户名称
                    }
                  }
                }
              }
            }
        ]]>
    </property>
 执行查询,通过bboss的searchList 方法获取符合条件的体检报告以及总记录数据,返回size对应的1000条数据
	/**
	 * 根据客户名称查询客户体检报告
	 */
	public void queryExamSearchByClientName(){
		ClientInterface clientUtil = ElasticSearchHelper.getConfigRestClientUtil("esmapper/Client_info.xml");
		Map<String,Object> params = new HashMap<String,Object>();
		params.put("clientName","张三");
		params.put("size",1000);
		ESDatas<Exam> exams = clientUtil.searchList("client_info/exam/_search","queryExamSearchByClientName",params,Exam.class);
		List<Exam> examList = exams.getDatas();//获取符合条件的体检数据
		long totalSize = exams.getTotalSize();//符合条件的总记录数据
	}
 
  • 根据子查父数据-通过医疗信息编码查找客户基本数据
在配置文件esmapper/Client_Info.xml增加查询dsl语句:queryClientInfoByMedicalName
    <!--通过医疗信息编码查找客户基本数据-->
    <property name="queryClientInfoByMedicalName">
        <![CDATA[
            {
              "query": {
                ## 最多返回size变量对应的记录条数
                "size":#[size],
                "has_child": {
                  "type":       "medical",
                  "score_mode": "max",
                  "query": {
                    "match": {
                      "medical_code": #[medicalCode] ## 通过变量medicalCode设置医疗编码
                    }
                  }
                }
              }
            }
        ]]>
    </property>

	}
5.同时返回父子数据-Elasticsearch 5.x 中如何在检索中同时返回父子数据 这一节中我们介绍同时返回父子数据的玩法 :inner_hits的妙用
  • 根据父条件查询所有子数据集合并返回父数据,根据客户名称查询所有体检数据,同时返回客户信息
在配置文件esmapper/Client_Info.xml增加检索dsl-queryDiagnosisByClientName
    <!--根据客户名称获取客户体检诊断数据,并返回客户信息-->
    <property name="queryDiagnosisByClientName">
        <![CDATA[
            {
              "query": {
                ## 最多返回size变量对应的记录条数
                "size":#[size],
                "has_parent": {
                  "type": "basic",
                  "query": {
                    "match": {
                      "client_name": #[clientName] ## 通过变量clientName设置客户名称
                    }
                  },
                  "inner_hits": {}  ## 通过变量inner_hits表示要返回对应的客户信息
                }
              }
            }
        ]]>
    </property>
执行检索并遍历结果
	/**
	 * 根据客户名称获取客户体检诊断数据,并返回客户数据
	 */
	public void queryDiagnosisByClientName(){

		ClientInterface clientUtil = ElasticSearchHelper.getConfigRestClientUtil("esmapper/Client_info.xml");
		Map<String,Object> params = new HashMap<String,Object>();
		params.put("clientName","张三");
		params.put("size",1000);

		try {
			ESInnerHitSerialThreadLocal.setESInnerTypeReferences(Basic.class);//指定inner查询结果对应的客户基本信息类型,Basic只有一个文档类型,索引不需要显示指定basic对应的mapping type名称
			ESDatas<Diagnosis> diagnosiss = clientUtil.searchList("client_info/diagnosis/_search",
					"queryDiagnosisByClientName",params,Diagnosis.class);
			List<Diagnosis> diagnosisList = diagnosiss.getDatas();//获取符合条件的体检报告数据
			long totalSize = diagnosiss.getTotalSize();
			//遍历诊断报告信息,并查看报告对应的客户基本信息
			for(int i = 0;  diagnosisList != null && i < diagnosisList.size(); i ++) {
				Diagnosis diagnosis = diagnosisList.get(i);
				List<Basic> basics = ResultUtil.getInnerHits(diagnosis.getInnerHits(), "basic");
				if(basics != null) {
					System.out.println(basics.size());
				}
			}
		}
		finally{
			ESInnerHitSerialThreadLocal.clean();//清空inner查询结果对应的客户基本信息类型
		}
	}
  •  根据子条件查询父数据并返回符合条件的父的子数据集合,查询客户信息,同时返回客户对应的所有体检报告、医疗记录、诊断记录
