这个jackson 太高 版本可能会导致冲突 无法正常运行

 

 

 

 

 

 

 覆盖掉默认的版本

 

 

 

添加对应的elasticSearch配置类

 

 

 

@Configuration
public class ElasticSearchConfiguration {
    @Bean
    public RestHighLevelClient restHighLevelClient(){
        //可以在builder 中添加多个主机
        RestClientBuilder builder = RestClient.builder(new HttpHost("192.168.1.137", 9200, "http"));
        RestHighLevelClient client = new RestHighLevelClient(builder);
        return client;
    }
    
}
