若依框架对接LDAP

这里直接使用spring ldap实现认证。

背景在若依框架上对接LDAP

代码

引入依赖

 <!-- 对接ldap -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-ldap</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-configuration-processor</artifactId>
            <optional>true</optional>
        </dependency>

        <dependency>
            <groupId>com.unboundid</groupId>
            <artifactId>unboundid-ldapsdk</artifactId>
            <scope>test</scope>
        </dependency>

配置参数

spring:  
  ldap:
    urls: ldap://192.168.10.130
    base: dc=example,dc=com
    username: cn=Manager,dc=example,dc=com
    password: your secret

重写LdapTemplate

@Configuration
public class LdapConfiguration {
    @Value("${spring.ldap.urls}")
    private String urls;
    @Value("${spring.ldap.base}")
    private String base;
    @Value("${spring.ldap.username}")
    private String username;
    @Value("${spring.ldap.password}")
    private String password;
    
    private LdapTemplate ldapTemplate;
    
    @Bean
    public LdapContextSource contextSource() {
        LdapContextSource contextSource = new LdapContextSource();
        Map<String, Object> config = new HashMap<>();
        // 处理乱码
        config.put("java.naming.ldap.attributes.binary", "objectGUID");
        
        contextSource.setUrl(urls);
        contextSource.setBase(base);
        contextSource.setUserDn(username);
        contextSource.setPassword(password);
        // 不使用已经创建好连接
        //  如果使用已经创建连接，去验证，总是失败的
        contextSource.setPooled(true);
        contextSource.setBaseEnvironmentProperties(config);
        // 验证必填参数都设置好
        contextSource.afterPropertiesSet();
        return contextSource;
    }
    
    @Bean
    public LdapTemplate ldapTemplate() {
        if (ldapTemplate == null) {
            ldapTemplate = new LdapTemplate(contextSource());
        }
        return ldapTemplate;
    }

LDAP person对象

根据实际LDAP服务的person名和具体属性

@Data
@Entry(base = "ou=People ", objectClasses = "inetOrgPerson")
public class LdapPerson {
    @Id
    @JsonIgnore
    private Name id;
    
    @DnAttribute(value = "uid")
    private String uid;
    
    @Attribute(name = "cn")
    private String cn;
    
    @Attribute(name = "sn")
    private String sn;
    
    @Attribute(name = "mobile")
    private String mobile;

    @Attribute(name = "mail")
    private String mail;
    
    @Attribute(name = "businessCategory")
    private String businessCategory;
    
    @Attribute(name = "departmentNumber")
    private String departmentNumber;
}

若依登入服务适配LDAP

在文件SysLoginService.java中（当前代码是2022.12月）

1.新增ldapValidate()方法（ldap认证，成功则将该账号自动注册）

2.在认证失败报错有"不存在"，则调用ldapValidate()方法，再重新认证一次

@Component
public class SysLoginService
{
    private static final Logger logger = LoggerFactory.getLogger(SysLoginService.class);
    
    @Autowired
    private TokenService tokenService;

    @Resource
    private AuthenticationManager authenticationManager;

    @Autowired
    private RedisCache redisCache;
    
    @Autowired
    private ISysUserService userService;

    @Autowired
    private ISysConfigService configService;

    @Resource
    private LdapTemplate ldapTemplate;
    
    @Resource
    private SysDeptMapper sysDeptMapper;
    
    @Resource
    private SysUserRoleMapper sysUserRoleMapper;

    /**

     */
    public String login(String username, String password, String code, String uuid)
    {
        boolean captchaEnabled = configService.selectCaptchaEnabled();
        // 验证码开关
        if (captchaEnabled)
        {
            validateCaptcha(username, code, uuid);
        }

            // 该方法会去调用UserDetailsServiceImpl.loadUserByUsername
            authentication = authenticationManager.authenticate(authenticationToken);
        }

增加一些sql

需要根据实际添加部门，否则新增用户没有部门id。
后续实际配置部门，权限等

insert into sys_dept values(500,  0,   '0',          'example',   0, '达网', '15888888888', 'ry@qq.com', '0', '0', 'admin', sysdate(), '', null);insert into sys_dept values(503,  500, '0,500',  '研发部门',   1, '若依', '15888888888', 'ry@qq.com', '0', '0', 'admin', sysdate(), '', null);
insert into sys_dept values(504,  500, '0,500',  '高级产品经理',   2, '若依', '15888888888', 'ry@qq.com', '0', '0', 'admin', sysdate(), '', null);
insert into sys_dept values(505,  500, '0,500',  '产品经理',   3, '若依', '15888888888', 'ry@qq.com', '0', '0', 'admin', sysdate(), '', null);
