Question

我无法在从html页面发出请求时呈现视图。以下是详细信息： 1）controllers.js文件

$scope.getAllApps = function() {
            $scope.applications = [];
            var getAllApplicationsUrl = _appContext+"/application/get";
            $http.get(getAllApplicationsUrl);
    }

2）ApplicationController.java文件

@RequestMapping(value="/get")
    public String getAllApplications() throws ApplicationException {
            throw new ApplicationException("Testing error page...");
            //return applicationService.getAllApplications();
    }

    @ExceptionHandler(value = Exception.class)
    public static ModelAndView redirectOnException(Exception e) {
            ModelAndView mv = new ModelAndView("error");
            mv.addObject("errMsg", e.getMessage());
            return mv;
    }

3）在DEBUG模式下的StackTrace：

如您所见，视图已成功返回，但未呈现error.jsp页面。我可以在chrome调试器中看到响应页面已返回，但它没有呈现。

当我从浏览器直接获取请求时，它可以工作（呈现error.jsp）。但是，当我点击'applicationForm.html'页面上的'获取应用'按钮时，不会呈现error.jsp（但是响应是由spring控制器发送的）。

提前致谢...

Spring MVC返回响应，但不呈现视图
