springBoot2.0+elasticsearch6.3 整合报错信息

新建微服务项目时，没有加载依赖包，直接复制官网MAVEN地址过来，各种包不兼容，冲突之后启动报错

直接抛出异常，包名冲突

解决方案  对应的版本号，排队没必要的版本，之前是5.6版本，主要看transport-netty4-client这个，下面是完整导入就正常了

	
	<dependency> 
	<groupId>org.elasticsearch</groupId> 
	<artifactId>elasticsearch</artifactId> 
	<version>6.3.0</version>
	</dependency> 
	<dependency> 
	<groupId>org.elasticsearch.client</groupId> 
	<artifactId>transport</artifactId> 
	<version>6.3.0</version> 
	<exclusions> 
	<exclusion> 
	<groupId>org.elasticsearch.plugin</groupId> 
	<artifactId>transport-netty4-client</artifactId> 
	</exclusion> 
	</exclusions> 
	</dependency> 
	<dependency> 
	<groupId>org.elasticsearch.plugin</groupId> 
	<artifactId>transport-netty4-client</artifactId> 
	<version>6.3.0</version>
	</dependency>
	

   主要是下面这两个包，在仓库里找下，看是不是跟elasticsearch版本一样，否则通信出错

   transport-netty4-client\6.3.0\transport-netty4-client-6.3.0.jar
   
    transport-netty3-client\5.6.2\transport-netty3-client-5.6.2.jar
    

错误 二，单纯的spingBoot 项目， 启动报错

Unregistering JMX-exposed beans on shutdown

没有加载依赖web 包的原因，只做微服务写后台， 应该可以不加载web 依赖包，那就加上，重启一切OK

            <groupId>org.springframework.boot</groupId>  
            <artifactId>spring-boot-starter-web</artifactId>
