[list]
[*]导入spring boot elasticsearch starter
[*]单个es集群案例

[size=medium][b]1.导入spring boot elasticsearch starter[/b][/size]
在spring boot项目中导入spring boot elasticsearch starter

maven工程

        
            com.bbossgroups.plugins
            bboss-elasticsearch-spring-boot-starter
            5.0.9.8
        

gradle工程

compile "com.bbossgroups.plugins:bboss-elasticsearch-spring-boot-starter:5.0.9.8"

[size=medium][b]2.创建spring boot启动类[/b][/size]
新建Application类：

package org.bboss.elasticsearchtest.springboot;


import org.frameworkset.elasticsearch.ElasticSearchHelper;
import org.frameworkset.elasticsearch.client.ClientInterface;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;

/**
 *  @author yinbp [[email protected]]
 *  
 */

@SpringBootApplication

public class Application {

    private Logger logger = LoggerFactory.getLogger(Application.class);


    public static void main(String[] args) {

        SpringApplication.run(Application.class, args);
    }
}

Application类中定义了一个main方法用来启动spring boot elasticsearch测试应用。

Application类将被用于启动下面两个测试用例：
[list]
[*]单es集群测试用例
[*]多es集群测试用例
[/list]
定义elasticsearch rest client组件实列管理类ServiceApiUtil：

import org.frameworkset.elasticsearch.ElasticSearchHelper;

/**

 */
@Service
public class ServiceApiUtil {


   /**

    * @return
    */
   public ClientInterface restClient(){
      return  ElasticSearchHelper.getRestClientUtil();
   }

   /**
    * 获取操作默认的es集群的加载dsl配置文件的客户端工具组件
    * @return
    */
   public ClientInterface restDemoConfigClient(){
      return  ElasticSearchHelper.getConfigRestClientUtil("esmapper/demo.xml");
   }

   /**
    * 获取操作logs的es集群的客户端工具组件
    * @return
    */
   public ClientInterface restClientLogs(){
      return  ElasticSearchHelper.getRestClientUtil("logs");
   }
   /**

    * @return
    */
   public ClientInterface restConfigClientLogs(){
      return  ElasticSearchHelper.getConfigRestClientUtil("logs","esmapper/demo.xml");
   }
}

实列管理类ServiceApiUtil将被注入到后续的测试用例中。

[size=medium][b]3.单es集群配置和使用[/b][/size]
[size=medium][b]3.1 配置单es集群[/b][/size]
修改spring boot配置文件application.properties内容（yml格式配置文件参考下面的内容配置）：

##ES集群配置
spring.elasticsearch.bboss.elasticUser=elastic

spring.elasticsearch.bboss.elasticsearch.showTemplate=true
spring.elasticsearch.bboss.elasticsearch.discoverHost=false
# dsl配置文件热加载扫描时间间隔，毫秒为单位，默认5秒扫描一次，<= 0时关闭扫描机制
spring.elasticsearch.bboss.dslfile.refreshInterval = -1

##es client http连接池配置
spring.elasticsearch.bboss.http.timeoutConnection = 400000
spring.elasticsearch.bboss.http.timeoutSocket = 400000
spring.elasticsearch.bboss.http.connectionRequestTimeout=400000
spring.elasticsearch.bboss.http.retryTime = 1
spring.elasticsearch.bboss.http.maxLineLength = -1
spring.elasticsearch.bboss.http.maxHeaderCount = 200
spring.elasticsearch.bboss.http.maxTotal = 400
spring.elasticsearch.bboss.http.defaultMaxPerRoute = 200
spring.elasticsearch.bboss.http.soReuseAddress = false
spring.elasticsearch.bboss.http.soKeepAlive = false
spring.elasticsearch.bboss.http.timeToLive = 3600000
spring.elasticsearch.bboss.http.keepAlive = 3600000
spring.elasticsearch.bboss.http.keystore =
spring.elasticsearch.bboss.http.keyPassword =
# ssl 主机名称校验，是否采用default配置，
# 如果指定为default，就采用DefaultHostnameVerifier,否则采用 SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER
spring.elasticsearch.bboss.http.hostnameVerifier =

## 数据库数据源配置，使用db-es数据导入功能时需要配置
#spring.elasticsearch.bboss.db.name = test
#spring.elasticsearch.bboss.db.user = root
#spring.elasticsearch.bboss.db.password = 123456
#spring.elasticsearch.bboss.db.driver = com.mysql.jdbc.Driver
#spring.elasticsearch.bboss.db.url = jdbc:mysql://localhost:3306/bboss
#spring.elasticsearch.bboss.db.usePool = false
#spring.elasticsearch.bboss.db.validateSQL = select 1

单ES集群配置项都是以spring.elasticsearch.bboss开头。

[size=medium][b]4.1 配置多es集群[/b][/size]
修改spring boot配置文件application-multi-datasource.properties，内容如下：

spring.elasticsearch.bboss.default.elasticsearch.showTemplate=true
spring.elasticsearch.bboss.default.elasticsearch.discoverHost=false

##default连接池配置
spring.elasticsearch.bboss.default.http.timeoutConnection = 400000
spring.elasticsearch.bboss.default.http.timeoutSocket = 400000
spring.elasticsearch.bboss.default.http.connectionRequestTimeout=400000

##logs集群对应的连接池配置
spring.elasticsearch.bboss.logs.http.timeoutConnection = 400000
spring.elasticsearch.bboss.logs.http.timeoutSocket = 400000
spring.elasticsearch.bboss.logs.http.connectionRequestTimeout=400000

spring.elasticsearch.bboss.logs.http.hostnameVerifier =
# dsl配置文件热加载扫描时间间隔，毫秒为单位，默认5秒扫描一次，<= 0时关闭扫描机制
spring.elasticsearch.bboss.dslfile.refreshInterval = -1

配置说明：

上面配置了两个集群：default和logs

每个集群配置项的前缀为：spring.elasticsearch.bboss.集群名字，其中的集群名字是一个自定义的逻辑名称，用来在client api中引用集群。

default集群的配置项前缀为：

spring.elasticsearch.bboss.default
logs集群的配置项前缀为：

spring.elasticsearch.bboss.logs
同时每个集群的配置项目里面必须包含name项目的配置

default集群name配置：

spring.elasticsearch.bboss.default.name = default
logs集群name配置：

##logs集群配置
spring.elasticsearch.bboss.logs.name = logs
