Spring Boot Rest集成

Question

我有一个例外：

@RestController
public class UserController {

@Autowired
    private IUserService userService;

    @RequestMapping(value="/getAllusers",method = RequestMethod.GET)
    public ResponseEntity<List<UserDTO>> getAllusers(){
        List<UserDTO> users=userService.getAllusers();
        return new ResponseEntity<List<UserDTO>>(users, HttpStatus.FOUND);

@Service公共类UserService实现IUserService{

public List<UserDTO> getAllusers(){
    List<UserDTO> users = new ArrayList<>();
    UserDTO userDTO = new UserDTO(1,"""","""");
    users.add(userDTO);
    return users;

}

@SpringBootApplication

public static void main(String args[]) {
SpringApplication.run(SpringAPP.class, args);
}

@anojsingh:看来你的组件没有被spring Boot扫描到。

UserService.java和SpringApp.java在同一个包中吗？如果不是，则需要提到@ComponentScan(BasePackages={“”}）示例:@ComponentScan(BasePackages={“com.rest.*”}）。在SpringApp.java类内部。

示例：-

@SpringBootApplication
@ComponentScan(basePackages= {"com.rest.*"})
public class SpringAPP{
