使用Spring 3在应用程序引擎中处理（400）错误 [英] Error handling (400) in app engine with Spring 3

问题描述

我想在我的应用程序引擎应用程序中处理错误400.


我可以使用以下代码处理404错误：

  @RequestMapping（/ **）
 public void unmappedRequest（HttpServletRequest request）{
 request.getRequestURI（）; 
 String uri = request.getRequestURI（）; 
 throw new UnknownResourceException（没有路径的资源
 + uri）; 
} 
  

然后我管理404错误。

然而，对于400错误（不好的请求），我尝试过这样的一个例子：

在web.xml中

 < error-page> 
< error-code> 400< / error-code> 
< location> / error / 400< / location> 
< / error-page> 
  

然后在我的控制器中

  @RequestMapping（/ error / 400）
 public void badRequest（HttpServletRequest request）{
 request.getRequestURI（）; 
 String uri = request.getRequestURI（）; 
 throw new UnknownResourceException（bad request for path+ uri）; 
} 
  

但它不起作用，所以我得到默认错误屏幕从应用引擎发出一个不好的请求。

任何建议？

解决方案

最简单快捷的解决方案我终于做了这样的事情：

  @ControllerAdvice 
 public class ControllerHandler {
 
 @ExceptionHandler（MissingServletRequestParameterException.class）
 public String handleMyException（异常异常，
 HttpServletRequest请求）{
 return/ error / myerror; 
} 
} 
  

这里的关键是处理org.springframework。 web.bind。 MissingServletRequestParameterException ;

其他替代方法也可以通过web.xml完成​​，如下所示：

 < error-page> 
< exception-type> org.springframework.web.bind.MissingServletRequestParameterException< / exception-type> 
< location> /WEB-INF/error/myerror.jsp< / location> 
< / error-page> 
  

I want to handle in my app engine application the error 400.

I could handle the 404 error using the following code:

@RequestMapping("/**")
public void unmappedRequest(HttpServletRequest request) {
    request.getRequestURI();
    String uri = request.getRequestURI();
    throw new UnknownResourceException("There is no resource for path "
    + uri);
}

and then i manage the 404 error.

However, for the 400 error (bad request), I tried something like this:

in web.xml

  <error-page>
    <error-code>400</error-code>
    <location>/error/400</location>
  </error-page>

and then in my controller

@RequestMapping("/error/400")
public void badRequest(HttpServletRequest request) {
    request.getRequestURI();
    String uri = request.getRequestURI();
    throw new UnknownResourceException("bad request for path " + uri);
}

But it doesn't work, so I'm getting the default error screen from app engine when I make a bad request.
Any suggestions?

解决方案

the easiest and quickest solution I got finally was doing something like this:

@ControllerAdvice
public class ControllerHandler {

    @ExceptionHandler(MissingServletRequestParameterException.class)
    public String handleMyException(Exception exception,
        HttpServletRequest request) {
    return "/error/myerror";
    }
}

The key here is to handle the org.springframework.web.bind.MissingServletRequestParameterException;

Other alternative, It also can be done through the web.xml, like the following:

<error-page>
    <exception-type>org.springframework.web.bind.MissingServletRequestParameterException</exception-type>
    <location>/WEB-INF/error/myerror.jsp</location>
</error-page>
