尝试在Spring Boot应用程序中处理异常时,日志中的ErrorPageFilter错误

MrC*_*MrC 14 java error-handling exception spring-boot

我做了一个小的Spring Boot应用程序,现在我正在尝试添加自己的异常处理.即使应用程序按预期工作,我也遇到了日志中出现错误的问题.配置:

  • Tomcat 8(独立)
  • Spring Boot版本1.2.3
  • 战争包装


异常处理程序如下所示:

@ControllerAdvice
public class GlobalExceptionHandler {

@ResponseStatus(HttpStatus.NOT_FOUND)
@ExceptionHandler(NotFoundException.class)
@ResponseBody ErrorInfo handleNotFoundRequest(HttpServletRequest req, Exception ex) {
    return new ErrorInfo(req.getRequestURL().toString(), ex);
}

}

我的控制器抛出异常:

@RequestMapping(value = "/{id}", method = RequestMethod.GET, produces = {"application/json"})
public @ResponseBody
HashMap environment(@PathVariable("id") long id)  {
    HashMap<String, Object> map = new HashMap();
    Environment env = environmentService.getEnvironment(id);

    if(env == null) throw new NotFoundException("Environment not found: " + id);

    map.put("environment", env);

    return map;
}

我的Spring Boot应用程序设置:

@SpringBootApplication
@EnableAutoConfiguration(exclude=ErrorMvcAutoConfiguration.class)
@ComponentScan
public class QaApiApplication {

public static void main(String[] args) {
    SpringApplication.run(QaApiApplication.class, args);
}
}

    return application.sources(QaApiApplication.class);
}

如果我执行一个生成异常的调用,我会得到正确的响应,即带有预期JSON的404.但是我在日志中看到ErrorPageFilter错误:

2015-04-09 21:05:38.647 ERROR 85940 --- [io-8080-exec-16] osboot.context.web.ErrorPageFilter:无法转发到请求[/ environments/1]的错误页面,因为响应已经一直致力于.因此,响应可能具有错误的状态代码.如果您的应用程序在WebSphere Application Server上运行,则可以通过将com.ibm.ws.webcontainer.invokeFlushAfterService设置为false来解决此问题


启动/部署没有错误,就我所见,一切似乎都有效.我怀疑有一些默认行为,我没有正确地覆盖,但我还没弄清楚到底是什么.

任何有关这方面的帮助/提示都会非常感激,因为我已经陷入了问题所在.

如果您仍然使用 Spring-boot 版本 1.2.3(不是提供解决方案的1.4.2.RELEASE ),则扩展SpringBootServletInitializer并覆盖方法run如下:

@SpringBootApplication
@EnableAutoConfiguration(exclude=ErrorMvcAutoConfiguration.class)
@ComponentScan
public class QaApiApplication extends SpringBootServletInitializer {
    public static void main(String[] args) {
         SpringApplication.run(QaApiApplication.class, args);
    }

    @Override
    protected WebApplicationContext run(SpringApplication application) {
        application.getSources().remove(ErrorPageFilter.class);
        return super.run(application);
    }
}

这个对我有用。
