java - 没有使用hibernate和Spring MVC定义名为'myUserDetailsS​​ervice'的bean

我正在遵循this tutorial，但是我需要在没有hbm.xml文件的情况下进行查询，而是使用dao和service层。我已经使用休眠为user和user_roles表生成了模型。我还创建了dao和服务层。

问题是我收到一条错误消息，提示未定义名为“ myUserDetailsS​​ervice”的bean。我知道我必须创建一个bean，但是我不知道该怎么做。

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'myUserDetailsService' is defined

我已经将整个项目上传到了github。任何帮助/建议都非常重要。

我的豆子：

 <bean id="userDao" class="com.mkyong.users.dao.UserDaoImpl">
        <property name="sessionFactory" ref="hibernate4AnnotatedSessionFactory" />
    </bean>
    <bean id="userService" class="com.mkyong.users.service.UserServiceImpl">
        <property name="userDao" ref="userDao"></property>
    </bean>

<!--    <bean id="myUserDetailsService" class="com.mkyong.users.service.MyUserDetailsService"> -->
<!--        <property name="userDao" ref="userDao" /> -->
<!--    </bean> -->

完整的MyUserDetailsS​​ervice类：

公共类MyUserDetailsS​​ervice实现UserDetailsS​​ervice {

private UserService userservice;

@Override
public UserDetails loadUserByUsername(final String username) throws UsernameNotFoundException {

    // Programmatic transaction management
    /*
    return transactionTemplate.execute(new TransactionCallback<UserDetails>() {

        public UserDetails doInTransaction(TransactionStatus status) {
            com.mkyong.users.model.User user = userDao.findByUserName(username);
            List<GrantedAuthority> authorities = buildUserAuthority(user.getUserRole());

            return buildUserForAuthentication(user, authorities);
        }

    });*/

    Users user = userservice.findByUserName(username);
    List<GrantedAuthority> authorities = buildUserAuthority(user.getUserRoleses());

    return buildUserForAuthentication(user, authorities);


}

// Converts com.mkyong.users.model.User user to
// org.springframework.security.core.userdetails.User
private User buildUserForAuthentication(Users user, List<GrantedAuthority> authorities) {
    return new User(user.getUsername(), user.getPassword(), user.isEnabled(), true, true, true, authorities);
}

private List<GrantedAuthority> buildUserAuthority(Set<UserRoles> userRoles) {

    Set<GrantedAuthority> setAuths = new HashSet<GrantedAuthority>();

    // Build user's authorities
    for (UserRoles userRole : userRoles) {
        setAuths.add(new SimpleGrantedAuthority(userRole.getRole()));
    }

    List<GrantedAuthority> Result = new ArrayList<GrantedAuthority>(setAuths);

    return Result;
}

}

最佳答案

错误非常清楚：


  没有定义名为“ myUserDetailsS​​ervice”的bean


在文件spring-security.xml中，您引用了一个名为myUserDetailsS​​ervice的bean：

<authentication-manager>
    <authentication-provider user-service-ref="myUserDetailsService" >
        <password-encoder hash="bcrypt" />
    </authentication-provider>
</authentication-manager>

但是，您已经注释掉了spring-database.xml中定义该服务的部分

<!--    <bean id="myUserDetailsService" class="com.mkyong.users.service.MyUserDetailsService"> -->
<!--        <property name="userDao" ref="userDao" /> -->
<!--    </bean> -->

这就是为什么会发生错误
