我无法为我的测试添加注释以@WebMvcTest使其正常工作。我还配置了spring-cloud-config-server和spring-cloud-starter，所有带有这个注解的Test类好像都失败了。我有以下控制器测试：

代码：

@RunWith(SpringRunner.class)
@WebMvcTest(controllers = UserController.class)
@ActiveProfiles({"dev", "native"})
public class UserControllerTest {

    @MockBean
    private UserService userService;
    @Autowired
    private MockMvc mockMvc;
    @Autowired
    private ObjectMapper objectMapper;

    @Test
    public void changePassword() throws Exception {
        given(userService.changePassword(any(), any(), any())).willReturn(true);
        MvcResult result = mockMvc.perform(post(/user/changePassword)
                .param("old", "Pa$$W0rd")
                .param("new, "NewPa$$W0rd"))
                .andExpect(status().isOk()).andReturn();
        assertThat(result).isNotNull();
    assertThat(result.getResponse().getContentAsString()).isEqualTo("true");
    }
}

相关控制器：

@RestController
@RequestMapping(/user)
@Log4j2
public class UserController {

    private UserService userService;

    public UserController(UserService userService) {
        this.userService = userService;
    }

    @Timed
    @PostMapping(value = /changePassword)
    public ResponseEntity changePassword(@RequestParam("old") String oldPassword,
                                         @RequestParam("new") String newPassword) …

我想知道如何检查第一列中的一行是否作为另一个文件中另一行的一部分存在。例如，如果我有以下文件：

a.txt:

我想返回文件“b.txt”中第二列的值，其中文件“a.txt”和“b.txt”中第一列的值匹配（内部联接排序）。因此，如果该文件位于输出文件“c.txt”中，我想要以下输出：

c.txt:

000000
000001
000002
000003
000004
000005
000007
000008
000009
000011
000012
000013
000016
000017

请注意，文件“b.txt”第二列中不存在这些值：

000006
000010
000014
000015

我尝试到处寻找，但找不到任何可以帮助解决问题的具体内容。感谢您的帮助。

谢谢！
