Java 在SpringMVC上组合@ExceptionHandler和@ResponseBy时出错

这是我的控制器：

@Controller
@RequestMapping("/UserController")
public class UserController {
    // ...
    @ExceptionHandler(UserServiceException.class)
    @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
    @ResponseBody
    public Object handleUserServiceException(UserServiceException e) {
        UserResponse userResponse = new UserResponse();
        String errorMsg = ("Operation failed for userName=" + e.getUser().getUserName() + " errorMsg=" + e.getErrorMsg());
        logger.error(errorMsg, e);
        userResponse.setResponseCode(e.getResCode());
        userResponse.setResponseMsg(e.getErrorMsg());
        return userResponse;
    }

我正在使用mockMVC测试此代码：

 ResultActions ra = this.mockMvc.perform(post("/UserController/updateAttributes").session(mockSession)
                .contentType(APPLICATION_JSON_UTF8).content(mapper.writeValueAsBytes(requestBody)));
        ra.andDo(print());
        ra.andExpect(status().isOk())
                .andExpect(jsonPath("$.responseCode").value(1));

我得到这个错误：

知道为什么

@ExceptionHandler

不能与

@ResponseBody

一起工作吗？在常规情况下（没有

@ExceptionHandler

），它可以正常工作。

您使用的是Spring 3还是Spring 4？为什么要混合使用Jackson版本（1和2）。它们不兼容，要么使用1，要么使用2。请说明您使用的是哪个Spring版本，因为现在看起来您至少在使用旧类（即

AnnotationMethodHandlerAdapter

，您可能应该使用

RequestMappingHandlerAdapter

）。还要确保使用

注册所有必要的bean。简言之，在您的问题中添加一些配置，那么您的配置至少有一些问题，因为您使用的是旧的Spring2.5bean，而实际上您应该使用3.x版本的Spring2.5bean。如前所述，您可以添加配置（还可以修复那些jackson依赖项，因为它们会在某一点上产生干扰）。
