【Elasticsearch】getConfigRestClientUtil和getRestClientUtil区别

1.getConfigRestClientUtil例子

获取在配置文件中根据DSL名称定义的DSL并执行它

ClientInterface clientUtil = ElasticSearchHelper.getConfigRestClientUtil("esmapper/sql.xml");//define an instanceof ConfigRestClientUtil,It's single instance, multithreaded secure.  
Map params = new HashMap();  
params.put("channelId",1);  
List<Map> json = clientUtil.sql(Map.class,"sqlQuery",params); 

sql.xml：

<properties>  
    <!--  
        sql query  
    -->  
    <property name="sqlQuery">  
        <!\[CDATA\[  
         {"query": "SELECT * FROM dbclobdemo where channelId=#\[channelId\]"}  
        \]\]>  
    </property>  
</properties> 

2.getRestClientUtil例子

直接执行代码中定义的DSL。

ClientInterface clientUtil = ElasticSearchHelper.getRestClientUtil();//define an instanceof RestClientUtil,It's single instance, multithreaded secure.  
List<Map> json = clientUtil.sql(Map.class,"{\\"query\\": \\"SELECT * FROM demo\\"}");
