尝试使用spring-boot-starter-data-jpa启动弹簧启动项目时，我遇到了这个特殊错误。奇怪的是，我的应用程序将在添加一些存储库和服务之前启动，但我似乎无法缩小为什么spring无法初始化在添加之前工作的存储库。
以下是相关错误：

最有趣的是这条线：
11：38：43.583 ERROR org.springframework.boot.context.embedded.tomcat.TomcatStarter.onStartup（）@ 63 [localhost-startStop-1] - 启动Tomcat上下文时出错。例外：org.springframework.beans.factory.BeanCreationException。消息：创建名称为＆＃39; emailAuthenticationFilter＆＃39;在类路径资源[gg / leet / security / WebSecurityConfig.class]中定义：通过工厂方法的Bean实例化失败;嵌套异常是org.springframework.beans.BeanInstantiationException：无法实例化[gg.leet.security.EmailAuthenticationFilter]：工厂方法＆＃39; emailAuthenticationFilter＆＃39;抛出异常;嵌套异常是org.springframework.beans.factory.BeanCreationException：创建名称为＆＃39; authenticationManager＆＃39;的bean时出错。在类路径资源[gg / leet / security / WebSecurityConfig.class]中定义：通过工厂方法的Bean实例化失败;嵌套异常是org.springframework.beans.BeanInstantiationException：无法实例化[org.springframework.security.authentication.AuthenticationManager]：工厂方法＆＃39; authenticationManager＆＃39;抛出异常;嵌套异常是org.springframework.beans.factory.UnsatisfiedDependencyException：创建名称为＆＃39; emailAuthenticationProvider的bean时出错：通过字段＆＃39; userService＆＃39;表达的不满意依赖性嵌套异常是org.springframework.beans.factory.UnsatisfiedDependencyException：使用名称＆＃39; userServiceImpl＆＃39;创建bean时出错。在文件[/Users/andrew/Programs/leet-tournaments/backend/build/classes/main/gg/leet/service/UserServiceImpl.class]中定义：通过构造函数参数0表示的不满意的依赖关系;嵌套异常是org.springframework.beans.factory.BeanCreationException：创建名称为＆＃39; userRepository＆＃39;的bean时出错：无法创建内部bean＆＃39;（内部bean）＃76212c93＆＃39;类型为[org.springframework.orm.jpa.SharedEntityManagerCreator]时设置bean属性＆＃39; entityManager＆＃39 ;;嵌套异常是org.springframework.beans.factory.BeanCreationException：创建名为＆＃39;（内部bean）的bean时出错＃76212c93＆＃39;：无法解析对bean的引用＆＃39; entityManagerFactory＆＃39;设置构造函数参数时;嵌套异常是org.springframework.beans.factory.BeanCreationException：创建名称为＆＃39; entityManagerFactory＆＃39;的bean时出错。在类路径资源中定义[org / springframework / boot / autoconfigure / orm / jpa / HibernateJpaAutoConfiguration.class]：调用init方法失败;嵌套异常是javax.persistence.PersistenceException：[PersistenceUnit：default]无法构建Hibernate SessionFactory
所以userServiceImpl的{{1}}参数0中的违规类就是userRepository。
这就是我的UserRepository的样子：
package gg.leet.repository;
import gg.leet.model.User;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.stereotype.Repository;
import java.util.List;
import java.util.Optional;
@Repository
public interface UserRepository extends JpaRepository<User, Long> {
Optional<User> findByEmail(String email);
@Query("select u from User u where u.id = ?1")
Optional<User> findOneById(Long id);
User save(User user);
Optional<User> findOneByUsername(String username);
List<User> findByEmailContaining(String search);
List<User> findByFirstNameContaining(String search);
List<User> findByLastNameContaining(String search);
List<User> findByUsernameContaining(String search);
@Query("select u from User u where u.username like ?1 or u.firstName like ?1 or u.lastName like ?1")
Page<User> findByUsernameOrLastNameOrFirstNameContaining(String search, Pageable pageable);
}
UserService实施：
package gg.leet.service;
import gg.leet.model.User;
import gg.leet.repository.UserRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.stereotype.Service;
import java.util.*;
/**
* Implementation of the UserService over the mysql repository
*/
@SuppressWarnings("unused")
@Service
public class UserServiceImpl implements UserService {
private final UserRepository userRepository;
@Autowired
public UserServiceImpl(UserRepository userRepository) {
this.userRepository = userRepository;
}
@Override
public Optional<User> getByUsername(String username) {
return this.userRepository.findOneByUsername(username);
}
@Override
public Optional<User> getByEmail(String email) { return this.userRepository.findByEmail(email); }
@Override
public Optional<User> getById(Long id) {
return this.userRepository.findOneById(id);
}
@Override
public User save(User user) {
return userRepository.save(user);
}
@Override
public Page<User> findByContaining(String search, Pageable pageable) {
return this.userRepository.findByUsernameOrLastNameOrFirstNameContaining(search, pageable);
}
}
没有什么太花哨但我不明白为什么我们不能为验证过滤器实例化bean。这个错误有点泛，所以我不知道应该在哪里看。我尝试在配置类中手动初始化entityManagerFactory bean，并在@EnableJpaRepositories注释中引用它无济于事。关于我应该在哪里解决这个问题的任何建议？
