问题：

spring boot startup与spring boot JPA Starter的问题

闻安宜

2023-03-14

当我试图用spring-boot-starter-data-jpa启动我的spring boot项目时，我遇到了这个特殊的错误。奇怪的是，我的应用程序会在添加几个存储库和服务之前启动，但我似乎无法缩小为什么spring不能初始化一个在添加之前正在工作的存储库的范围。

以下是相关错误：

最有趣的是这句话：

11:38:43.583错误org.springframework.boot.context.embedde.Tomcat.tomcatstarter.onstartup()@63[localhost-startStop-1]-启动Tomcat上下文时出错。异常：org.springframework.beans.factory.beancreationexception。消息：创建类路径资源[gg/leet/security/websecurityconfig.class]中定义的名为'email authenticationfilter'的bean时出错：通过工厂方法实例化bean失败；嵌套异常为org.springframework.beans.beanInstantiationException：无法实例化[gg.leet.security.emailauthenticationfilter]:工厂方法'emailauthenticationfilter'引发异常；嵌套异常为org.springframework.beans.factory.beanCreationException：创建类路径资源[gg/leet/security/websecurityconfig.class]中定义的名为“authentication manager”的bean时出错：通过工厂方法实例化bean失败；嵌套异常为org.springframework.beans.beanInstantiationException：无法实例化[org.springframework.security.authentication.authenticationManager]:工厂方法“authentication Manager”引发异常；嵌套异常为org.springframework.beans.factory.unsatisfieddependencyexception：创建名为“email authenticationprovider”的bean时出错：通过字段“user service”表示的不满足依赖项；嵌套异常为org.springframework.beans.factory.unsatisfiedDependencyException：创建文件[/users/andrew/programs/leet-tournaments/backend/build//main/gg/leet/service/userserviceimpl.class]中定义的名为“user serviceimpl”的bean时出错：通过构造函数参数0表示的未满足的依赖项；嵌套异常为org.springframework.beans.factory.BeanCreationException：创建名为“User Repository”的bean时出错：设置bean属性“Entity Manager”时无法创建类型为[org.springframework.orm.jpa.SharedEntityManagerCreator]的内部bean“（内部bean)#76212C93”；嵌套异常为org.springframework.beans.factory.BeanCreationException：创建名为“（内部bean)#76212C93”的bean时出错：设置构造函数参数时无法解析对bean“Entity ManagerFactory”的引用；嵌套异常为org.springframework.beans.factory.beanCreationException：创建类路径资源[org/springframework/boot/autociguration/orm/jpa/hibernatejpaAutociguration.class]中定义的名为“Entity ManagerFactory”的bean时出错：调用init方法失败；嵌套异常为javax.persistence.persistenceException:[persistenceUnit:default]无法构建Hibernate SessionFactory

所以在userServiceImpl的参数0中的冒犯类是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实现：

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);
    }
}

没什么特别的，但我不明白为什么我们不能为身份验证过滤器实例化一个bean。这个错误有点一般，所以我不知道应该在哪里找。我尝试在配置类中手动初始化EntityManagerFactorybean，并在@enableJParepositories注释中引用它，但没有成功。有什么建议，我也应该看看哪里来解决这个问题？

spring数据存储库通常扩展自repository或crudrepository接口。如果您使用的是自动配置，那么将从包含主配置类（用@enableAutoConfiguration或@springbootapplication注释的类）的包中向下搜索存储库。

-spring boot参考指南，29.3.2 Spring Data JPA储存库。

实际上，我认为这是问题的解决方案（用粗体字体标记的文本）：

默认情况下，spring boot将启用JPA存储库支持，并查看@springbootapplication所在的包（及其子包）。如果您的配置的JPA存储库接口定义位于不可见的包中，则可以使用@enablejparepositories及其类型安全的basePackageClasses=myRepository.class参数指出备用包。

-入门·使用JPA访问数据。

总之，请考虑更新LeetTournaments类的实现，如下所示：

@EnableJpaRepositories(basePackageClasses = UserRepository.class)
public class LeetTournaments {
    ...
}

希望这有帮助。
