项目环境：

• jdk 1.8
• spring boot 1.5.1

由于spring boot 目前SpringBoot 1.5.1.RELEASE和Spring Data Elasticsearch 2.10.RELEASE仅支持ElasticSearch 2.4.0。 
他们不支持最新版本的ElasticSearch 5.x版本。

Spring Boot Version (x)Spring Data Elasticsearch Version (y)Elasticsearch Version (z)x <= 1.3.5y <= 1.3.4z <= 1.7.2*x >= 1.4.x2.0.0 <=y < 5.0.0**2.0.0 <= z < 5.0.0**

mavan 配置 pom.xml

: 特注

 ElasticSearch 5.x 根据官网配置maven 依赖, 由于 5.0x的 jar 内部使用的 apache log4日志。 所以要配置额外的依赖支持 org.apache.logging.log4j。

application-dev.yml

spring:     data:   elasticsearch:        cluster-name: elasticsearch        cluster-nodes: 127.0.0.1:9300
