我已经设法解决了一个问题，与 Spring 启动aop和模拟测试服务使用的方法在Spring AOP Aspect not working using Mockito中详细说明。
有没有新的方法？

• • 编辑**从我的具体实施中添加更多详细信息。

控制器：

@RestController
public class EndpointController {
    
    private EndpointService endpointService;
    
    @Autowired    
    public EndpointController(EndpointService endpointService) {
        this.endpointService = endpointService;
    }

    @PostMapping(path = "/endpoint", consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
    private @ResponseBody EndpointResponse doSomething(/* ... */, @RequestBody SomeObject someObject) throws Exception {
        return endpointService.doSomething(someObject);
    }
}

在我的测试类中，我有：

@RunWith(SpringRunner.class)
public class EndpointControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void shouldBeSuccessfulAccessingTheEndpoint() throws Exception {
        SomeObject someObject = new SomeObject(/* values */);

        ObjectMapper mapper = new ObjectMapper();
        String payload = mapper.writeValueAsString(someObject);

        mockMvc.perform(post("/endpoint").contentType(MediaType.APPLICTION_JSON).content(payload)).andExpect(status().isOK));
    }
}

失败，抛出NullPointerException异常，调试时endpointService始终为空。
有什么想法吗？
