继承了SimpleMappingExceptionResolver

贴上代码

/** * 对controller异常进行全局处理 * 区分了对普通请求和ajax请求的异常处理，普通请求返回到配置的errorCode页面，或者返回到指定的页面 * @author *  */public class CustomException extends SimpleMappingExceptionResolver {    private final transient Logger logger = LoggerFactory.getLogger(getClass());    @Override    protected ModelAndView doResolveException(HttpServletRequest request,            HttpServletResponse response, Object handler, Exception ex) {        String viewName = determineViewName(ex, request);        if (viewName != null) {
