您可以使用status.reason（）方法。
例如：
@Test public void loginWithBadCredentials() { this.mockMvc.perform( post("/rest/login") .contentType(MediaType.APPLICATION_JSON) .content("{"username": "baduser", "password": "invalidPassword"}") ) .andDo(MockMvcResultHandlers.print()) .andExpect(status().isUnauthorized()) .andExpect(status().reason(containsString("Bad credentials"))) .andExpect(unauthenticated()); } MockHttpServletResponse: Status = 401Error message = Authentication Failed: Bad credentials Content type = null Body = Forwarded URL = null Redirected URL = null cookies = []
