@Test public void update() throws Exception { GroupDO root = GroupDO.builder().name("root").info("致敬周星星").build(); GroupDO group = GroupDO.builder().name("少林足球").info("致敬周星星").build(); groupMapper.insert(root); groupMapper.insert(group); RegisterDTO dto = new RegisterDTO(); dto.setGroupIds(Arrays.asList(group.getId())); dto.setEmail(email); dto.setConfirmPassword(password); dto.setPassword(password); dto.setUsername(username); userService.createUser(dto); UserDO user = userService.getUserByUsername(username); LocalUser.setLocalUser(user); UpdateInfoDTO dto1 = new UpdateInfoDTO(); dto1.setEmail("23129982604@qq.com"); dto1.setUsername("pedro小小"); ObjectMapper mapper = new ObjectMapper(); mapper.setPropertyNamingStrategy(PropertyNamingStrategy.CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES); String content = mapper.writeValueAsString(dto1); mvc.perform(MockMvcRequestBuilders.put("/cms/user/") .contentType(MediaType.APPLICATION_JSON).content(content)) .andDo(print()) .andExpect(status().isOk()) .andExpect(MockMvcResultMatchers. jsonPath("$.message").value("更新用户成功")); UserDO user1 = userService.getUserByUsername("pedro小小"); assertTrue(user1.getEmail().equals("23129982604@qq.com")); }
