现在实现这一点的最简单方法(Spring Security 3.2.5.RELEASE)是实现自定义LdapAuthoritiesPopulator,它使用自定义JdbcDaoImpl从数据库中获取权限。
代码
假设您使用的是 the default database schema,并且您在 LDAP 中使用相同的用户名进行身份验证,并且作为 authorities 表中的外键,您只需要这个:
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);
}
}
现在唯一剩下的就是将 LDAP 身份验证提供程序配置为使用 CustomLdapAuthoritiesPopulator。
Java 配置
在GlobalMethodSecurityConfiguration 或WebSecurityConfigurerAdapter 的@Configuration 注释子类中(取决于您的情况),添加以下内容:
@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 */
}
有关工作示例,请参阅 https://github.com/pfac/howto-spring-security。
XML 配置
免责声明:我一直在使用 Java 配置,所以请谨慎行事,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,似乎没有漂亮的 XML 标记来自定义 LdapAuthoritiesPopulator。因此,必须手动完成。假设已经定义了一个配置与 LDAP 服务器连接的 bean contextSource,请将以下内容添加到您的 Spring XML 配置中:
<beans:bean id="customJdbcUserDetailsService" class="demo.CustomJdbcUserDetailsService" />
<beans:bean id="customLdapAuthoritiesPopulator" class="demo.CustomLdapAuthoritiesPopulator">
<beans:constructor-arg ref="customJdbcUserDetailsService" />
</beans:bean>
<beans:bean id="ldapAuthProvider" class="org.springframework.security.ldap.authentication.LdapAuthenticationProvider">
<beans:constructor-arg>
<beans:bean class="org.springframework.security.ldap.authentication.BindAuthenticator">
<beans:constructor-arg ref="contextSource" />
<!--
other configurations you might need
-->
</beans:bean>
</beans:constructor-arg>
<beans:constructor-arg ref="customLdapAuthoritiesPopulator" />
</beans:bean>
<security:authentication-manager>
<security:authentication-provider ref="ldapAuthProvider" />
</security:authentication-manager>
