我想在我的Spring MVC Web应用程序中处理404页面未找到异常，我正在使用SPRING 4.2.5.RELEASE，我已经阅读了有关此主题的几个问题，但是类似的问题正在使用不同的spring java配置。

我有一个具有所有异常的Global Exception Handler Controller类，该类工作正常，但我无法处理404页面未找到异常。

这是我遵循教程的方法

1）我创建了一个名为ResourceNotFoundExceptionfrom
的类，RuntimeException并将此注释放在类定义上@ResponseStatus(HttpStatus.NOT_FOUND)

像这样：

@ResponseStatus(HttpStatus.NOT_FOUND)
public class ResourceNotFoundException extends RuntimeException {

}

2）我在异常的控制器类中创建了此方法

@ExceptionHandler(ResourceNotFoundException.class)
@ResponseStatus(HttpStatus.NOT_FOUND)
public String handleResourceNotFoundException() {

    return "notFoundJSPPage";
}

但是，当我放置一个不存在的URL时，仍然出现此错误“找不到具有URI的HTTP请求的映射”

我读过的问题说我需要为Dispatcher启用一个选项，但是由于我的配置与其他问题不同，我没有，Web.xml所以无法应用。

这是我的Config.java

@EnableWebMvc
@Configuration
@ComponentScan({"config", "controllers"})
public class ConfigMVC extends WebMvcConfigurerAdapter {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("/WEB-INF/resources/");
    }

    @Bean
    public UrlBasedViewResolver setupViewResolver() {
        UrlBasedViewResolver resolver = new UrlBasedViewResolver();
        resolver.setPrefix("/WEB-INF/jsp/");
        resolver.setSuffix(".jsp");
        resolver.setViewClass(JstlView.class);
        return resolver;
    }

}

这是我的WebInitializer

public class WebInicializar implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
        ctx.register(ConfigMVC.class);
        ctx.setServletContext(servletContext);
        Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(ctx));
        servlet.addMapping("/");
        servlet.setLoadOnStartup(1);


    }
}

这是我的全局异常处理程序控制器

@ControllerAdvice
public class GlobalExceptionHandlerController {


    @ExceptionHandler(value = NullPointerException.class)
    public String handleNullPointerException(Exception e) {

        System.out.println("A null pointer exception ocurred " + e);

        return "nullpointerExceptionPage";
    }


    @ResponseStatus(value = HttpStatus.INTERNAL_SERVER_ERROR)
    @ExceptionHandler(value = Exception.class)
    public String handleAllException(Exception e) {

        System.out.println("A unknow Exception Ocurred: " + e);

        return "unknowExceptionPage";
    }


    @ExceptionHandler(ResourceNotFoundException.class)
    @ResponseStatus(HttpStatus.NOT_FOUND)
    public String handleResourceNotFoundException() {

        return "notFoundJSPPage";
    }

}

我创建的扩展了Runtime Exception的类

@ResponseStatus(HttpStatus.NOT_FOUND)
public class ResourceNotFoundException extends RuntimeException{

}

@Override
public void onStartup(ServletContext servletContext) throws ServletException {
    AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
    ctx.register(ConfigMVC.class);
    ctx.setServletContext(servletContext);
    Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(ctx));
    servlet.addMapping("/");
    servlet.setLoadOnStartup(1);
    servlet.setInitParameter("throwExceptionIfNoHandlerFound", "true");
}

@ExceptionHandler(NoHandlerFoundException.class)
@ResponseStatus(HttpStatus.NOT_FOUND)
public String handle(NoHandlerFoundException ex) {

  return "my404Page";
}
