Question

是否可以使用Spring 3.2.1实现基于自定义HTTP 404错误页面的注释？我在各种论坛上寻找方法，但找不到任何明确的答案。

我也尝试使用web.xml进行配置，但是在访问未映射的URL时它无法正常工作。有什么帮助吗？

记录输出

  7259 [DEBUG] org.springframework.web.servlet.DispatcherServlet  - DispatcherServlet with name 'spring-test' processing GET request for [/spring-test/ss]
  7261 [DEBUG] org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping  - Looking up handler method for path /ss
  7262 [DEBUG] org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping  - Did not find handler method for [/ss]

  7262 [DEBUG] org.springframework.web.servlet.DispatcherServlet  - Successfully completed request

的web.xml

控制器

@Controller
@RequestMapping(value = "/errors")
public class CommonExceptionHandler {

    private static Logger log = Logger.getLogger(CommonExceptionHandler.class.getName());

    @RequestMapping(method = RequestMethod.GET, value = "/{code}")
    public ModelAndView handleException(@PathVariable int code) {

        if (log.isDebugEnabled()) {
            log.debug("ERROR CODE IS: " + code);
        }

        return new ModelAndView("errors/404");
    }

}

我有同样的问题。我有一个简单的webapp，单页，在Spring论坛上度过了一个早晨（很好，你不能搜索'404'，因为它只有3个字符长）和Google这是我发现的最佳解决方案。假设您有index.jsp和404.jsp，我的@Configuration'有：

@Override
public void addViewControllers(ViewControllerRegistry registry) {
    registry.addViewController("/").setViewName("index");
    registry.addViewController("/*").setViewName("404");
}
