Spring integration 尝试注入轮询器建议时出错

我已经在s3上实现了一个轮询策略，类似这样的东西。我正在进行一个webservice调用，以检查是否可以从s3轮询文件。如果我的webservice启动，那么我正在提取文件

 import org.springframework.http.HttpEntity;
    import org.springframework.http.HttpMethod;
    import org.springframework.http.ResponseEntity;
    import org.springframework.integration.scheduling.PollSkipStrategy;
    import org.springframework.jmx.export.annotation.ManagedOperation;
    import org.springframework.jmx.export.annotation.ManagedResource;
    import org.springframework.web.client.RestTemplate;


    @ManagedResource
    public class ServiceHealthCheckPollSkipStrategy  implements PollSkipStrategy  {


        private volatile boolean skip;

        @Override
        public boolean skipPoll() {

            RestTemplate restTemplate = new RestTemplate();
            HttpEntity<String> request = new HttpEntity<>(new String("bar"));
            ResponseEntity<String> response = restTemplate.
                      exchange("http://localhost:8080/RESTfulExample/rest/ca/mock/post", HttpMethod.OPTIONS, request, String.class);
            //Set<HttpMethod> result = restTemplate.optionsForAllow("http://localhost:8080/RESTfulExample/rest/ca/mock/post");


           if (response.getStatusCode().toString().equals("200")){
               this.skip = true;
           }
            return this.skip;
        }

        /**
         * Skip future polls.
         */
        @ManagedOperation
        public void skipPolls() {
            this.skip = true;
        }


        /**
         * Resume polling at the next {@code Trigger} event.
         */
        @ManagedOperation
        public void reset() {
            this.skip = false;
        }
    }

---

首先，我想通过

response.getStatusCode（）.toString（）.equals（“200”）

true

结果，您不应该

跳过当前轮询，而应该真正允许从S3源获取文件。所以，请修改一下你的逻辑

关于

Caused by: java.lang.IllegalArgumentException: class org.springframework.integration.http.config.HttpIntegrationConfigurationInitializer is not assignable to interface org.springframework.integration.config.IntegrationConfigurationInitializer

我确信这是类装入器的问题。在这里，我猜您将
spring集成http
放在XD模块类路径中，它应该放在父
XD\lib
类路径中

尽管我不认为有理由担心
spring集成http
，因为原始
springweb
应该足够了，因为您只使用代码中的
restemplate

诀窍是：在看到XD不接受具有公共类路径的模块之前，不要在模块类路径中放置任何内容
