报错信息如下：
Error creating bean with name ‘elasticsearchTemplate‘ defined in class path
解决思路：
1.es版本与pom文件版本不符
修改pom文件mvn版本
2.jar包冲突
将冲突的jar包exclusion
<dependency> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId> <version>6.2.4</version> </dependency> <!-- https://mvnrepository.com/artifact/org.elasticsearch.client/transport --> <dependency> <groupId>org.elasticsearch.client</groupId> <artifactId>transport</artifactId> <version>6.2.4</version> <exclusions> <exclusion> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId> </exclusion> </exclusions> </dependency>
3.启动类中设置
public static void main(String[] args) {
SpringApplication.run(EsDemoApplication.class, args);
System.setProperty("es.set.netty.runtime.available.processors", "false");
}
4.es版本与idea不兼容
注释以下pom
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-elasticsearch</artifactId> </dependency>
手动添加pom依赖
<dependency> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId> <version>6.2.4</version> </dependency> <!-- https://mvnrepository.com/artifact/org.elasticsearch.client/transport --> <dependency> <groupId>org.elasticsearch.client</groupId> <artifactId>transport</artifactId> <version>6.2.4</version> <exclusions> <exclusion> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.elasticsearch.client</groupId> <artifactId>elasticsearch-rest-high-level-client</artifactId> <version>6.2.4</version> <exclusions> <exclusion> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId> </exclusion> </exclusions> </dependency>
