春季安全3：腌制密码问题

问题描述

限时删除！！

我有一个简单的应用程序，可以在其中注册用户并对其进行身份验证。我已经使用密码编码并成功验证了它们。我在我的应用程序中使用了Spring 3，Spring Security 3和Hibernate 3.

现在我想用密码填入用户的ID，但我无法实现这一功能。有人能帮我实现吗？我一直在尝试做相当长的一段时间，但不能完成它。

这里是我用来腌制用户的代码ID和身份验证。

< intercept-url pattern =/ welcome.doaccess =hasRole（'ROLE_USER'）/> 
< form-login login-page =/ login.doauthentication-failure-url =/ login.do?login_error=1\"/>

有人能帮我理解我在这里错过了什么吗？ 
非常感谢。 
 
解决方案 
  ReflectionSaltSource   UserDetails 的实例。但是使用 org.springframework.security.core.userdetails.User 作为 UserDetails 的实现，它不会' t有一个名为 id 的属性（而不是你在 UserDetailsAdapter 中有这个属性，这是没有意义的，因为 UserDetailsAdapter 是一个单例）。
 
 
所以，你需要创建一个 org.springframework.security.core.userdetails.User 与 id 属性，并从您的 UserDetailsAdapter 。
 
I have got an simple application made in which I am able to register users and authenticate them. I've got the passwords encoded using and successfully able to authenticate them. I am using Spring 3, Spring Security 3 and Hibernate 3 in my application.

Now I want to salt their passwords with the ID of the user but I am not able to achieve this functionality. Could someone help me achieve it? I've been trying to do it for quite some time but ain't able to get it done.

Here is the code I've got for salting users with their ID and authenticating them.

xyz-security.xml
<http auto-config="true" use-expressions="true">
    <intercept-url pattern="/welcome.do" access="hasRole('ROLE_USER')" />
    <form-login login-page="/login.do" authentication-failure-url="/login.do?login_error=1"/>
    <logout invalidate-session="true" logout-url="/logout" logout-success-url="/"/>
</http>

<beans:bean id="daoAuthenticationProvider"  class="org.springframework.security.authentication.dao.DaoAuthenticationProvider">
    <beans:property name="userDetailsService" ref="userDetailsService"/>
</beans:bean>

<beans:bean id="authenticationManager" class="org.springframework.security.authentication.ProviderManager">
    <beans:property name="providers">
        <beans:list>
            <beans:ref local="daoAuthenticationProvider" />
        </beans:list>
    </beans:property>
</beans:bean>

<authentication-manager>
    <authentication-provider user-service-ref="userDetailsService">
        <password-encoder ref="passwordEncoder">
            <salt-source ref="saltSource"/>
            </password-encoder>
    </authentication-provider>
</authentication-manager>

<!-- For hashing and salting user passwords -->
<beans:bean id="passwordEncoder" class="org.springframework.security.authentication.encoding.ShaPasswordEncoder"/>
<beans:bean id="saltSource" class="org.springframework.security.authentication.dao.ReflectionSaltSource"
    p:userPropertyToUse="id"/>

        String password = userEntity.getPassword();
        boolean enabled = userEntity.isEnabled();
        boolean accountNonExpired = true;
        boolean credentialsNonExpired = true;
        boolean accountNonLocked = true;

        Collection<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
        for (String authority: userEntity.getAuthorities()) {

            authorities.add(new GrantedAuthorityImpl(authority));
        }

        this.id = userEntity.getId();

        org.springframework.security.core.userdetails.User user = new org.springframework.security.core.userdetails.User(username, password, enabled, accountNonExpired, credentialsNonExpired, accountNonLocked, authorities);
        return user;
    }

        UserDetails userDetails = null;
        User userEntity = userDao.findByUsername(username);

        if (userEntity == null) {
          throw new UsernameNotFoundException("user not found");
        }
        userDetails = userDetailsAdapter.buildUserFromUserEntity(userEntity);

        return userDetails;

    public User getByUsername(String username) {
        return userDao.findByUsername(username);
    }

    public User getByEmail(String email) {
        return userDao.findByEmail(email);
    }

    public void createUser(User user) {
        userDao.create(user);

        UserDetailsAdapter userDetailsAdapter = new UserDetailsAdapter();
        org.springframework.security.core.userdetails.User userDetails =  userDetailsAdapter.buildUserFromUserEntity(user);
        String password = userDetails.getPassword();
        Object salt = saltSource.getSalt(userDetails);
        user.setPassword(passwordEncoder.encodePassword(password, salt));
        userDao.update(user);

    }

    public void updateUser(User user) {
        userDao.update(user);
    }
}
Could someone help me understand what am I missing here?Many thanks.
 解决方案 
ReflectionSaltSource extracts a salt from the instance of UserDetails. But you use org.springframework.security.core.userdetails.User as an implementation of UserDetails, and it doesn't have a property named id (instead of that you have this property in UserDetailsAdapter, that doesn't make sense, since UserDetailsAdapter is a singleton).
So, you need to create a subclass of org.springframework.security.core.userdetails.User with id property, and return it from your UserDetailsAdapter.
