尽管我设置了delete-credentials =“ false”，但在ldap的Spring Security 3.1中，getPassword（）返回null。

Question

我需要获取登录用户的用户名和密码，才能使用这些凭据重新连接到另一个产品。

这是我的SecurityContext.xml

    <property name="userAccessService" ref="userAccessService" />
</bean>
<bean id="loginFailuerHandler" class="com.eblacorp.archive.security.LoginFailuerHandler" />
</beans>

当我使用此代码打印用户名和密码时，密码显示为空。

UserDetails user = (UserDetails) SecurityContextHolder.getContext()
            .getAuthentication().getPrincipal();

    System.out.println("username: " + user.getUsername());
    System.out.println("password: " + user.getPassword());

我在身份验证管理器中将delete-credentials =“ false”设置为：

<security:authentication-manager erase-credentials="false" >
    <security:authentication-provider
        ref="ldapAuthProvider" />
</security:authentication-manager>

要获取密码值，请使用getCredentials（）。

• 对象getCredentials（）

证明主体正确的凭据。 这通常是密码，但可以是与AuthenticationManager相关的任何内容。 呼叫者应填充凭据。

返回：证明委托人身份的凭证
