java – 使用MockMvc获取httpServletRequest属性

@RequestMapping(value = "/api/test",method = RequestMethod.GET,produces = "application/json")
public @ResponseBody Object getObject(HttpServletRequest req,HttpServletResponse res) {
    Object userId = req.getAttribute("userId");
    if (userId == null){
        res.setStatus(HttpStatus.BAD_REQUEST.value());
    }
    [....]
}

我尝试以许多不同的方式使用MockMvc调用,但是,我无法提供属性“userId”.

例如,有了它,它不起作用：

MockHttpSession mockHttpSession = new MockHttpSession(); 
mockHttpSession.setAttribute("userId","TESTUSER");             
mockMvc.perform(get("/api/test").session(mockHttpSession)).andExpect(status().is(200)).andReturn();

我也试过这个,但没有成功：

MvcResult result = mockMvc.perform(get("/api/test").with(new RequestPostProcessor() {
     public MockHttpServletRequest postProcessRequest(MockHttpServletRequest request) {
           request.setParameter("userId","testUserId");
           request.setRemoteUser("TESTUSER");
           return request;
     }
})).andExpect(status().is(200)).andReturn();

在这种情况下,我可以设置RemoteUser但不能在HttpServletRequest上设置Attributes映射.

任何线索？
