elasticsearch-client-spring-boot-starter

在spring boot中使用spring-elasticsearch-client

1. 依赖

<dependency>
     <groupId>com.github.baiczsy</groupId>
     <artifactId>elasticsearch-client-spring-boot-starter</artifactId>
     <version>1.0.0</version>
</dependency>

注意，由于依赖的是elasticsearch-rest-high-level-client 7.0.0版本，需要替换spring boot集成的低版本，避免依赖冲突。

<properties>
      <!-- 替换spring boot的低版本 -->
      <elasticsearch.version>7.0.0</elasticsearch.version>
</properties>

2. application.yml配置

spring:
  elasticsearch:
    nodes:
      - 192.168.0.100:9200
      - 192.168.0.101:9200
      - 192.168.0.102:9200
    client:
      connect-timeout: 1000
      connection-request-timeout: 500
      socket-timeout: 20000
      max-conn-total: 100
      max-conn-per-route: 100 
      headers: {header1: value1, header2: value2}
    pool:
      min-idle: 5
      max-idle: 8
      max-active: 20
      max-wait: 1000ms

3. 注入RestClientTemplate

@Autowired
private RestClientTemplate template;
