Day 11 -父子关系维护检索实战一 - Elasticsearch 5.x-父子关系维护
Elasticsearch | 作者 yinbp | 发布于2018年12月11日 | | 阅读数：4002
本次分享包括两篇文章
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：
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
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：
3.维护父子关系数据-Elasticsearch 5.x 中维护父子关系数据
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
通过注解@ESId指定基本信息文档_id
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。
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：
在配置文件esmapper/Client_Info.xml增加dsl语句：queryExamSearchByClientName
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
在配置文件esmapper/Client_Info.xml增加查询dsl语句：queryClientInfoByMedicalName
这一节中我们介绍同时返回父子数据的玩法 ：inner_hits的妙用
在配置文件esmapper/Client_Info.xml增加检索dsl-queryDiagnosisByClientName
在配置文件esmapper/Client_Info.xml增加检索dsl-queryClientAndAllSons
到此Elasticsearch 5.x 父子关系维护检索实战介绍完毕，谢谢大家！

</property>
</properties>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：
