Java SpringBean复制版：“；在null中定义的bean无法注册；。Can'；我找不到

我正在编写一个简单的Spring JPA测试应用程序，并得到一个错误：“在null中定义的bean‘userRepository’无法注册。具有该名称的bean已经在null中定义，并且重写被禁用。”。我知道它指向bean复制，但我真的很困惑到底哪里是该死的复制。我想仅仅打开bean覆盖并不是一个好的选择。 请帮忙

该应用程序的结构是：

用户类

package com.mot.platform.bean;

import org.springframework.data.annotation.Id;

import javax.persistence.*;

@Entity
@Table(name="plan_user")
public class User {

   @Id
   @Column(name = "id", nullable = false)
   private Long id;

   @Column(name = "name", length = 255, nullable = false)
   private String name;

   @Column(name = "password", length = 255, nullable = false)
   private String password;

   public Long getId() {
      return id;
   }

   public void setId(Long id) {
      this.id = id;
   }  

   public String getName() {
      return name;
   }

   public void setName(String name) {
      this.name = name;
   }

   public String getPassword() {
      return password;
   }

   public void setPassword(String password) {
      this.password = password;
   }
}
'''

**UserRepository class**<br />
'''
package com.mot.platform.model;

import org.springframework.stereotype.Repository;
import com.mot.platform.bean.User;
import org.springframework.data.repository.CrudRepository;

@Repository
public interface UserRepository extends CrudRepository<User, Long> {
    //User findById(long id);
}

UserServiceImpl类

package com.mot.platform.model;

import com.mot.platform.bean.User;

public interface UserService {

    public void addUser (String name, String password);
    public User getUserById (Long id);

}

UserServiceImpl

package com.mot.platform.model;

import org.springframework.stereotype.Service;

import com.mot.platform.bean.User;
import java.util.Optional;

@Service
public class UsrServiceImpl implements UserService {

  //  @Autowired
    private UserRepository rep;

    public void addUser(String name, String password) {
        User user = new User();
        user.setName("TestHiber");
        user.setPassword("ttt");
        rep.save(user);
    }

    public User getUserById(Long id) {
        Optional<User> optusr = rep.findById(id);
        User usr = optusr.isPresent() ? optusr.get() : null;
        return usr;
     }
}

除了附加在这里之外，我没有其他文件/类。

关于

UserRepository

的代码呢？为什么

/@Autowired

是

UsrServiceImpl

中的注释？这是一个配置问题。请务必完成此操作，可能您在配置类的某个位置多次使用了

@EnableJpaRepositories

注释。抱歉，忘记附加UserRepository代码。现在是空的。添加了用户存储库代码。

package com.motivation.platform.model;

import org.springframework.stereotype.Repository;
import com.mot.platform.bean.User;
import org.springframework.data.repository.CrudRepository;

@Repository
public interface UserRepository extends CrudRepository<User, Long> {
  }
