Question

我有一个spring boot 1.3.3应用程序。我有一个休息控制器，在某些情况下抛出异常。抛出异常并打印消息，但未触发ControllerAdvice类。这是我的相关文件： TestController.java

@Controller
public class TestController {
    // RESTful method
    @RequestMapping(
            value = "/test",
            method = RequestMethod.POST,
            consumes = "application/json",
            produces = "application/json")
    @ResponseBody
    public JsonNode fooRestTest(@RequestHeader HttpHeaders header,
            @RequestBody String payload) {
        ControllerUtil.validateHeaders(header);
        return null;
    }
}

ControllerUtil.java

public class ControllerUtil {
    public static void validateHeaders(HttpHeaders headers) {
        if(headers.get("test-field") == null) {
            throw new InvalidHeaderException("Invalid test-field in header");
        }
    }
}

InvalidHeaderException.java

public class InvalidHeaderException extends RuntimeException {


    public InvalidHeaderException(String message) {
        super(message);
    }

    public InvalidHeaderException(String message, Throwable cause) {
        super(message, cause);
    }
}

AppErrorController.java

@ControllerAdvice
@EnableWebMvc
public class AppErrorController {

    @ExceptionHandler(InvalidHeaderException.class)
    public ModelAndView handleHeaderError(HttpServletRequest req, Exception 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;
    }
}

的web.xml

<web-app id="RBGApp" version="3.0"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

        <servlet-name>Foo_Test</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <!-- Mappings -->
    <servlet-mapping>
        <servlet-name>Foo_Test</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

MvcConfiguration.java

@Configuration
@EnableWebMvc
public class MvcConfiguration extends WebMvcConfigurerAdapter {
    @Autowired
    ServletContext servletContext;

    @Override
    public void configureDefaultServletHandling(
            DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

    @Bean
    public ViewResolver getJspViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("WEB-INF/jsp/views/");
        resolver.setSuffix(".jsp");
        resolver.setOrder(1);
        return resolver;
    }
}

我使用邮递员的请求对此进行了测试，并抛出异常并打印出该行：

Invalid test-field in header

但代码永远不会进入AppErrorController。因此，不会填充像timestamp这样的其他值。知道我在这里做错了吗？

Answer 1

您的日志文件中是否包含java.lang.IllegalStateException: No suitable resolver for argument等消息？

尝试在 handleHeaderError 方法参数中使用相同的异常类型： InvalidHeaderException 而不是 Exception 。像这样：

@ControllerAdvice
@EnableWebMvc
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;
}

}

Answer 2

可能有一些处理此请求的其他处理程序（from first 5 lines of console output）。这可能出现在项目构建路径中的任何jar中。

我们需要将处理程序的优先级设置为最高，因此控件首先来到这里。

我认为在@Order(Ordered.HIGHEST_PRECEDENCE)之后添加@EnableWebMvc可能会解决问题。

@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;
}

此外，如果它不起作用，请尝试将InvalidHeaderException.class更改为Exception.class（无论它控制的是什么异常，都会来到这里）。在你的情况下，调试也会有所帮助。

ControllerAdvice不处理异常
