在我们的新保险项目中,我正尝试使用Ldap spring-security实施active-directory。
一旦用户在AD中找到,我想只检查用户名/密码。我想从用户表(app授权用户)授权他在数据库中具有访问级别。有人可以提供样品/指出我的资源。

现在实现这一目标的最简单方法(Spring Security 3.2.5.RELEASE)是通过实现自定义LdapAuthoritiesPopulator
,使用自定义JdbcDaoImpl
从数据库中获取权限。
假设您正在使用the default database schema,并且您在LDAP中使用相同的用户名进行身份验证,并使用authorities
表中的外键,则只需要:
package demo;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.Collection;
import java.util.List;
import org.springframework.jdbc.core.RowMapper;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.AuthorityUtils;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.core.userdetails.jdbc.JdbcDaoImpl;
import org.springframework.ldap.core.DirContextOperations;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.ldap.userdetails.LdapAuthoritiesPopulator;
/*
* You need to extend JdbcDaoImpl to expose the protected method loadUserAuthorities.
*/
public class CustomJdbcUserDetailsService extends JdbcDaoImpl {
@Override
public List<GrantedAuthority> loadUserAuthorities(String username) {
return super.loadUserAuthorities(username);
}
}
/*
* Then, the only thing your populator needs to do is use the custom UserDetailsService above.
*/
public class CustomLdapAuthoritiesPopulator implements LdapAuthoritiesPopulator {
private static final Logger LOGGER = LoggerFactory.getLogger(CustomLdapAuthoritiesPopulator.class);
private CustomJdbcUserDetailsService service;
public CustomLdapAuthoritiesPopulator(CustomJdbcUserDetailsService service) {
this.service = service;
}
public Collection<? extends GrantedAuthority> getGrantedAuthorities(DirContextOperations user, String username) {
return service.loadUserAuthorities(username);
}
}
现在唯一要做的就是配置LDAP身份验证提供程序以使用CustomLdapAuthoritiesPopulator
。
在@Configuration
或GlobalMethodSecurityConfiguration
的{{1}}注释子类中(视您的情况而定),添加以下内容:
WebSecurityConfigurerAdapter
有关工作示例,请参阅https://github.com/pfac/howto-spring-security。
免责声明:我一直专注于Java配置,因此谨慎行事,可能会出现一些错误。
与使用LDAP进行身份验证的其他配置不同,似乎没有可用于自定义@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
/* other authentication configurations you might have */
/*
* This assumes that the dataSource configuring
* the connection to the database has been Autowired
* into this bean.
*
* Adapt according to your specific case.
*/
CustomJdbcUserDetailsService customJdbcUserDetailsService = new CustomJdbcUserDetailsService();
customJdbcUserDetailsService.setDataSource(dataSource);
CustomLdapAuthoritiesPopulator customLdapAuthoritiesPopulator = new CustomLdapAuthoritiesPopulator(customJdbcUserDetailsService);
auth.ldapAuthentication().ldapAuthoritiesPopulator(customLdapAuthoritiesPopulator)/* other LDAP configurations you might have */;
/* yet more authentication configurations you might have */
}
的漂亮XML标记。所以,它必须手动完成。假设已经定义了配置与LDAP服务器的连接的bean LdapAuthoritiesPopulator
,请将以下内容添加到Spring XML配置中:
contextSource

您很可能必须执行自定义UserDetailsServer,因为您通过LDAP进行身份验证,但通过数据库查询获取角色。 UserDetailsService是一个接口。您将实现该接口,然后将您的自定义实现添加到Spring Security配置中,执行以下操作:
<beans:bean id="userDetailsService" class="com.app.MyUserDetailsServiceImpl" />
<authentication-manager>
<authentication-provider user-service-ref="userDetailsService">
<password-encoder hash="plaintext" />
</authentication-provider>
</authentication-manager>
在loadUserByUsername()中,您将创建一个UserDetails,设置用户名,密码和“权限”,即角色。
