我已经在s3上实现了一个类似于这的事情的轮询策略。我正在进行webservice调用，检查我是否可以从s3轮询文件，如果我的webservice已启动，那么我正在拉文件
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;
}
}

答案 0 :(得分：1)
首先我想通过response.getStatusCode().toString().equals("200") true结果你不应该skip当前的民意调查，但真的允许从S3来源中提取文件。所以，请在那里修改你的逻辑。
关于
Caused by: java.lang.IllegalArgumentException: class org.springframework.integration.http.config.HttpIntegrationConfigurationInitializer is not assignable to interface org.springframework.integration.config.IntegrationConfigurationInitializer
我确定这是类加载器的问题。在这里，我猜你将spring-integration-http放在XD模块类路径中，它应放在父xd\lib类路径中。
虽然我没有理由担心spring-integration-http，因为原始spring-web对您来说应该足够了，因为您只使用代码中的RestTemplate。
配方是：在您看到XD不接受具有公共类路径的模块之前，不要向模块类路径放置任何内容。
