技术标签:
【中文标题】Spring -data-jpa ，存储库类不起作用【英文标题】：Spring -data-jpa , The Repository Class doesn`t work 【发布时间】：2019-03-02 14:31:13 【问题描述】：我正在 Springboot 中开发一个应用程序，使用 mysql5、spring-data-jpa、Java8...问题是我无法部署它，因为“找不到所需的 bean 'entityManagerFactory'”问题。我不t know where is the error and tried many soulutions but it doesnt 工作。
这是我的 SecurityConfig 类

## 这是我的 UserSecurityService 类##

@Service
@ComponentScan(basePackages="com.repositories")
public class UserSecurityService implements UserDetailsService
@Autowired
private UserRepository userRepository;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException
users user = userRepository.findByUsername(username);
if(null == user)
throw new UsernameNotFoundException("User not Found");
else
return user;
### 这是我的 userRepository 类###
package com.repositories;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;
import com.domains.users;
@Repository
public interface UserRepository extends CrudRepository<users , Long>
users findByUsername(String username);

【问题讨论】：
【参考方案1】：听起来好像是路径问题。 我猜你的“主要”方法在另一个包中作为你的服务。 通常在执行spring boot自动配置功能时会扫描主包及其子包以查找类路径依赖项。
但我认为你应该使用 @EnableJpaRepositories 来定义 repo 的位置（在主包之外）
例子：
package1.package2.repoclass package1.package3.mainclass package1.package3.serviceclass（服务注入 repo）
在服务器启动时会出现一条错误消息，该服务无法注入 repo，但当我使用 @EnableJpaRepositories(basePackages = "package1.package2") 时它可以工作
