Spring Security：无法在 UserDetailsS​​ervice 类中自动装配 DAO

Question

这个问题已经被问过很多次了，我累了很多解决方案但都失败了。

我正在尝试将用户映射到 Spring Security 用户。我的 security.xml 能够看到我的 userDao 类。我不明白为什么我不能自动连接我的课程。

我的 spring-security.xml

<?xml version="1.0" encoding="UTF-8"?>

我的 UsersDao 类

public interface UsersDAO {

    void saveOrUpdate(Users user);
    Users find(int userId);

}

我的 UsersDAOImpl 是：

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import com.memorize.dao.UsersDAO;
import com.memorize.model.Users;

public class UsersDAOImpl implements UsersDAO {

    @Autowired
    private SessionFactory sessionFactory;

    public void setSessionFactory(SessionFactory sf){
        this.sessionFactory = sf;
    }

    public void save(Users u) {
        Session session = this.sessionFactory.getCurrentSession();
        session.persist(u);
    }

    @Override
    public void saveOrUpdate(Users user) {
        // TODO Auto-generated method stub
        Session session = this.sessionFactory.getCurrentSession();
        session.persist(user);
    }

    @Override
    public Users find(int id) {
        // TODO Auto-generated method stub
        Session session = this.sessionFactory.getCurrentSession();
        return (Users) session.get(Users.class, id);
    }
}

更新

根据建议，我将我的 UsersDAOImpl 更改为：

我的 UsersDAOImpl 是：

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import com.memorize.dao.UsersDAO;
import com.memorize.model.Users;

@Repository
public class UsersDAOImpl implements UsersDAO {

    @Autowired
    private SessionFactory sessionFactory;

    public void setSessionFactory(SessionFactory sf){
        this.sessionFactory = sf;
    }

    public void save(Users u) {
        Session session = this.sessionFactory.getCurrentSession();
        session.persist(u);
    }

    @Override
    public void saveOrUpdate(Users user) {
        // TODO Auto-generated method stub
        Session session = this.sessionFactory.getCurrentSession();
        session.persist(user);
    }

    @Override
    public Users find(int id) {
        // TODO Auto-generated method stub
        Session session = this.sessionFactory.getCurrentSession();
        return (Users) session.get(Users.class, id);
    }
}

但是在这个改变之后，我得到了这个错误：

org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.hibernate.SessionFactory com.memorize.dao.impl.UsersDAOImpl.sessionFactory;
No qualifying bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. 
Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}.

现在我无法在 UsersDAOImpl 类下自动装配 sessionFactory。

Answer 1

在UsersDAO 实现中添加@Repository 注释，以便该类可以包含在组件扫描中

@Repository
public class UsersDAOImpl implements UsersDAO {

Answer 2

你正在扫描 com.memorize 是对的

  <context:component-scan base-package="com.memorize" /> 

但只有带有 @controller、@service、@component、@Repository 等注释的类才能成为自动关联的候选对象，而其他类则不是。因此请考虑相应地注释您的类以进行正确的自动关联。

@Component --> 任何 Spring 管理的组件的通用原型

@Repository--> 持久层的原型

@Service --> 服务层的原型

@Controller --> 表示层的原型（spring-mvc）

以下应该可以解决错误。

@Repository
public class UsersDAOImpl implements UsersDAO {
 @Autowired
private SessionFactory sessionFactory;

public void setSessionFactory(SessionFactory sf){
    this.sessionFactory = sf;
}

public void save(Users u) {
    Session session = this.sessionFactory.getCurrentSession();
    session.persist(u);
}

@Override
public void saveOrUpdate(Users user) {
    // TODO Auto-generated method stub
    Session session = this.sessionFactory.getCurrentSession();
    session.persist(user);
}

@Override
public Users find(int id) {
    // TODO Auto-generated method stub
    Session session = this.sessionFactory.getCurrentSession();
    return (Users) session.get(Users.class, id);
}

}

Answer 3

我相信你的配置的问题是UserDao bean 如果在不同的上下文中定义（servlet 的那个）。 SessionFactory 也一样，它不会自动连接。我的建议是将 common bean 移动到 root-context，它同时加载到 servlet 和 securitie 的上下文中。

一个例子：

root-context.xml

在根上下文中，我正在自动装配（通过组件扫描）每个不是 @Controller 的 bean

    <context:component-scan base-package="pl.com.suadeo.nwfm">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
        <context:exclude-filter type="regex" expression="pl.com.suadeo.nwfm.webservice.*"/>
    </context:component-scan>

    <bean class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer">
        <property name="locations">

        </property>
    </bean>

    <bean id="sessionFactory"

        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">${sessionFactory.hibernate.dialect}</prop>
                <prop key="hibernate.hbm2ddl.auto">${sessionFactory.hibernate.hbm2ddl.auto}</prop>

    </bean>

    <bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">

        <property name="cacheSeconds" value="${messageSource.cacheSeconds}"/>
    </bean>

</beans>

servlet-context.xml

在 servlet 上下文中，我正在扫描 @Controller 注释，启用 spring 安全性并设置一些其他相关的 servlet 配置

security-context.xml

在安全上下文中，我可以从根上下文中看到 bean，因此不需要额外的组件扫描

</beans:beans>

UserServiceImpl.java

然后在你的 UserServiceImpl 中，你可以自动装配你的 bean：

public class UserDetailsServiceImpl implements UserDetailsService {

    @Autowired
    private UserRepository userRepository;

    @Autowired
    private UserService userService;

    public UserDetails loadUserByUsername( String email ) throws UsernameNotFoundException, DataAccessException {
        User userEntity = userRepository.findByEmail( email );
        if ( userEntity == null ) {
            throw new UsernameNotFoundException( "user not found" );
        }

        return userService.buildUserFromUserEntity( userEntity );
    }
}

希望这会有所帮助
