创建名称为'loginServer'的bean时出错：无法自省bean类

这是我的代码

@Path("/umm")

public class LoginServer {
    private transient Logger log = LogManager.getLogger(this.getClass());
    @Context
    HttpServletRequest contextRequest;

@Path("/basicLogin")
@POST
public @ResponseBody Response login(@RequestBody(required = true) LoginRequest loginRequest){
    System.out.println("Hello World!");
    LoginResponse loginResponse = new LoginResponse();
    try {
        LoginClient loginClient = new LoginClient();
        loginResponse = loginClient.login(loginRequest,contextRequest);

        return null;

    } catch (Exception e) {
        log.error(e);
        return null;
    }       
}

我运行它并没有收到任何错误，但是当我使用“邮递员”进行测试时，却出现404错误

404 ERROR in Postman

但是当我尝试像这样替换@RestController @PostMapping @RequestMapping时。

@RestController
@RequestMapping(path = "/umm")
public class LoginServer {
    private transient Logger log = LogManager.getLogger(this.getClass());
    @Context
    HttpServletRequest contextRequest;

我收到此日志错误！

我不需要获取该错误和404错误。 ...............................................

答案 0 :(得分：0)

如果使用Spring，则必须使用批注@*Mapping，@Rest/Controller和@Autowired进行依赖注入。否则它将无法正常工作。

答案 1 :(得分：0)

添加此依赖项

<dependency>
    <groupId>javax.ws.rs</groupId>
    <artifactId>javax.ws.rs-api</artifactId>
    <version>2.0</version>
</dependency>

由于找不到javax.ws.rs.core.Response，因此抛出ClassNotFoundException
