我是Java的新手，嘗試了各種方法來解決這個問題，但沒有運氣。TestFeedService 接口對象 （testService） 值在 testService.sendMessage（dataBO， false） 調用時顯示為 null。這存在于我從測試用例調用的方法中。我不知道為什么會發生這種情況。我嘗試在 setup（） 中創建 Object，但仍然失敗。有人可以幫我嗎？下面是測試用例代碼public class testApiControllerTest {private MockMvc mockMvc;private TesApiController testApiController;private TestFeedService testService;@Beforepublic void setup() { testApiController = mock(TestApiController.class); testService = mock(TestFeedService.class); testService = new TestFeedServiceImpl();}@Testpublic void testProcessMessage() { TestApiController testApiController = new TestApiController(); TestForm2 testForm2 = new TestForm2(); testForm2.setType("PROMO_CODE"); testForm2.setUserId("1"); testForm2.setMessage("Welcome"); ResponseEntity<?> responseEntity = testApiController.processMessage(testForm2); assertEquals(HttpStatus.OK, responseEntity.getStatusCode());}}Java 代碼： public class TestApiController {@Autowiredprivate TestFeedService testService; // This is an interface @RequestMapping(path = "/api/process-message", method = RequestMethod.POST)public ResponseEntity<?> processMessage(@RequestBody TestForm2 testForm) { DataBO dataBO = convertBO(testForm); testService.sendMessage(dataBO, false); // here I am getting testService = null and causing exception return ResponseEntity.ok().build();} // Some more code

您需要將 TestService 放在 TestApiController 的構造函數中，以便在測試中創建對象時可以注入它。
public class TestApiController {
private TestFeedService testService; // This is an interface
@Autowired
public TestApiController(TestFeedService testService ) {
this.testService = testService;
}
@RequestMapping(path = "/api/process-message", method = RequestMethod.POST)
public ResponseEntity<?> processMessage(@RequestBody TestForm2 testForm) {
DataBO dataBO = convertBO(testForm);
testService.sendMessage(dataBO, false); // here I am getting testService = null and causing exception
return ResponseEntity.ok().build();
} // Some more code
所以你的測試是這樣的：
public class testApiControllerTest {
private MockMvc mockMvc;
private TesApiController testApiController;
private TestFeedService testService;
@Before
public void setup() {
this.testService = mock(TestFeedService.class);
}
@Test
public void testProcessMessage() {
this.testApiController = new TestApiController(this.testService);
// More code
}}
希望它有幫助
