使用logstash-input-jdbc如何将数据导入至同一索引下

小白一个，今天在学习使用logstash-input-jdbc同步mysql数据时，我想要将两个查询的数据分别放置在同一index下的不同type中，写法如下：

input {

    jdbc {

      jdbc_connection_string => "jdbc:mysql://localhost:3306/blog?zeroDateTimeBehavior=convertToNull&useSSL=true"

      jdbc_user => "root"

      jdbc_password => "root"

      jdbc_driver_library => "D:\dev\maven\repository\mysql\mysql-connector-java\5.1.38\mysql-connector-java-5.1.38.jar"

      jdbc_driver_class => "com.mysql.jdbc.Driver"

      statement => "select * from article;"

      schedule => "* * * * *"

      type => "article"

    }

    jdbc {

      jdbc_connection_string => "jdbc:mysql://localhost:3306/blog?zeroDateTimeBehavior=convertToNull&useSSL=true"

      jdbc_user => "root"

      jdbc_password => "root" 

      jdbc_driver_library => "D:\dev\maven\repository\mysql\mysql-connector-java\5.1.38\mysql-connector-java-5.1.38.jar"

      jdbc_driver_class => "com.mysql.jdbc.Driver"

      statement => "select * from icon;"

      schedule => "* * * * *"

      type => "icon"

    }

}

output {

 stdout {

        codec => json_lines

    }

    if[type] == "article"{

        elasticsearch {

        hosts  => "localhost:9200"

        index => "contacts4"

        document_type => "article"

        document_id => "%{id}"

        }

    }

    if[type] == "icon"{

        elasticsearch {

        hosts  => "localhost:9200"

        index => "contacts4"

        document_type => "icon"

        document_id => "%{id}"

        }

    }

}

它会给出警告，信息如下

][logstash.outputs.elasticsearch] Could not index event to Elasticsearch. {:status=>400, :action=>["index", {:_id=>"4", :_index=>"contacts4", :_type=>"article", :_routing=>nil}, #<LogStash::Event:0x611194af>], :response=>{"index"=>{"_index"=>"contacts4", "_type"=>"article", "_id"=>"4", "status"=>400, "error"=>{"type"=>"illegal_argument_exception", "reason"=>"Rejecting mapping update to [contacts4] as the final mapping would have more than 1 type: [icon, article]"}}}}

不能把这两个同时插入至同一index中的不同type，当我把他们分别插入至两个不同的索引时却是可以的
