我正在使用Java和spring引导。我有两个文件，一个@配置文件和一个@服务文件。

配置文件：

代码语言：javascript
运行

代码语言：javascript
运行
复制
@Configuration
    public class OpenSearchRestClientConfiguration {
        @Value("${aws.opensearch.domain.endpoint}")
        private String endpoint;
        @Value("${aws.region}")
        private String region;
        @Value("${aws.serviceName}")
        private String myServiceName;
    
    
        @Bean  //I get an error when I add @Bean, but when I remove @Bean, I get no errors.
        public OpenSearchClient OpensearchClient(){
            SdkHttpClient myHttpClient = ApacheHttpClient.builder().build();
    
            AWS4Signer mySigner = new AWS4Signer();
            mySigner.setServiceName(myServiceName);
            mySigner.setRegionName(region);
            return new OpenSearchClient(
                    new AwsSdk2Transport(myHttpClient, endpoint, Region.of(region), AwsSdk2TransportOptions.builder().build()));
    
    
        }
    }
代码语言：javascript
运行
复制

服务档案：

代码语言：javascript
运行
复制
@Service
public class PostsSearchService {

    
    private final OpenSearchRestClientConfiguration myOpenSearchClient;

    public PostsSearchService(OpenSearchRestClientConfiguration openSearchClient){

        this.myOpenSearchClient = openSearchClient;
    }
}

当我在OpensearchClient类中的OpenSearchRestClientConfiguration方法的顶部添加@Bean时，我会得到一个错误，但是当我删除@Bean时，我不会收到任何错误。

下面是我遇到的错误：

在**OpenSearchRestClientConfiguration **类中，在OpensearchClient *方法**中添加@Bean时会出现一个错误，但是当我删除@Bean注释时，不会出现错误。

这种错误背后的原因是什么？

spring
spring-boot
elasticsearch
opensearch
java

当您添加@Bean时，它告诉Spring按bean配置添加bean，正如您在文档bean配置.When中看到的那样，删除@Bean时，OpensearchClient()方法将不会被执行。而您获得错误ClassNotFoundException的原因可能是您忘记导入jakarta包或jakarta版本可能是错误的。
