我有一个spring boot 1.3.3应用程序。我有一个rest控制器，它在某些情况下抛出异常。将抛出异常并打印消息，但不会激发ControllerAdvice类。以下是我的相关文件： TestController.java

@Controller
public class TestController {
    // RESTful method
    @RequestMapping(
            value = "/test",

        ControllerUtil.validateHeaders(header);
        return null;
    }
}

    @ExceptionHandler(InvalidHeaderException.class)

        mav.addObject("exception", ex);
        mav.addObject("url", req.getRequestURL());
        mav.addObject("timestamp", LocalDateTime.now());
        mav.addObject("status", 400);
        return mav;
    }
}

ControllerUtil.java

我通过邮递员的请求对此进行了测试，它抛出异常并打印出行：

Invalid test-field in header

但是代码根本不会进入

AppErrorController

。因此，不会填充其他值，如

timestamp

。知道我做错了什么吗

编辑1: 这是邮递员的回应：

日志文件中是否有类似

java.lang.IllegalStateException:没有合适的参数解析程序的消息
尝试在handleHeaderError方法参数处使用相同的异常类型：InvalidHeaderException而不是exception。像这样：
@ControllerAdvice
@EnableWebMvc
@Order(Ordered.HIGHEST_PRECEDENCE)
public class AppErrorController {

@ExceptionHandler(InvalidHeaderException.class)
public ModelAndView handleHeaderError(HttpServletRequest req, InvalidHeaderException ex) {
    ModelAndView mav = new ModelAndView();
    mav.addObject("exception", ex);
    mav.addObject("url", req.getRequestURL());
    mav.addObject("timestamp", LocalDateTime.now());
    mav.addObject("status", 400);
    return mav;
}

}
可能有其他处理程序正在处理此请求（，从控制台输出的前5行开始）。这可能在项目的构建路径中的任何jar中
我们需要将处理程序的优先级设置为最高，所以首先要进行控制
我认为在@EnableWebMvc
之后添加@Order（Ordered.HIGHEST_priority）
可能会解决这个问题
此外，如果它不起作用，请尝试将InvalidHeaderException.class
更改为Exception.class
（不管它是什么异常，控制都会出现在这里）。在您的情况下，调试也会很有帮助。
…您可以添加一个日志语句并再次检查它吗？看起来它的配置很好。更新了我的帖子。正如您所看到的，ControllerAdvice根本不参与此响应。应该有一个时间戳字段，错误代码应该是400。您可以从该控制器中删除@EnableWebMvc
注释并重试吗。您是否在某个地方（Bitbucket、GitHub、GitLab）有该项目，以便我们查看？此外，您从未设置过视图名
，不知道它如何知道去哪里…是什么让您认为返回“状态”为400的模型（没有视图）会改变引发某些异常的结果？？看，我也试过了，但还是不起作用。我发布了控制台输出。没有抛出IllegalStateException。
@ControllerAdvice
@EnableWebMvc
@Order(Ordered.HIGHEST_PRECEDENCE)
public class AppErrorController {

@ExceptionHandler(InvalidHeaderException.class)
public ModelAndView handleHeaderError(HttpServletRequest req, InvalidHeaderException ex) {
    ModelAndView mav = new ModelAndView();
    mav.addObject("exception", ex);
    mav.addObject("url", req.getRequestURL());
    mav.addObject("timestamp", LocalDateTime.now());
    mav.addObject("status", 400);
    return mav;
}
