Shiro最佳实践（四）基于ini配置文件的自定义认证

Apache Shiro

---

本文所谓的基于ini配置文件的自定义认证是从ini文件中定义用户账户及角色权限信息，通过自己实现Realm的方式进行登录授权，比较简单，参考具体如下：

配置文件

#按用户名与密码登录
 [users]
 chendd=www.chendd.cn,admin,manager
 
 [roles]
 admin=*
 manager="user:insert,update,delete","concat:*"

自定义授权

package cn.chendd.shiro.custom;
 
 import ...;
 
 /**
  * @author chendd
  * 自定义登录认证实现
  */
 public class LoginRealm extends IniRealm {
 
     Logger logger = LoggerFactory.getLogger(this.getClass());
 
     public LoginRealm(String resourcePath) {
         super(resourcePath);
     }
 
     /**
      * 自定义认证器名称
      */
     @Override
     public String getName() {
         return "chendd-login-realem";
     }
 
     @Override
     protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
         UsernamePasswordToken userToken = (UsernamePasswordToken) token;
         logger.debug("待认证的用户名为：{}，密码为：{}" ,
                 userToken.getUsername() , userToken.getPassword());
         SimpleAccount account = this.getUser(userToken.getUsername());
         if(account == null){
             throw new UnknownAccountException("用户不存在！");
         }
         if(! account.getCredentials().toString().equals(new String(userToken.getPassword()))){
             throw new AuthenticationException("用户名或密码不匹配！");
         }
         Object credentials = account.getCredentials();
         Object principal = token.getPrincipal();
         //将用户account对象存储至用户账号主体中
         SimpleAuthenticationInfo authInfo = new SimpleAuthenticationInfo(account , credentials , this.getName());
         return authInfo;
     }
 
     @Override
     protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
         //获取主体用户账号信息，将账号中的角色、权限信息进行授权
         SimpleAccount account = (SimpleAccount) principals.getPrimaryPrincipal();
         SimpleAuthorizationInfo simpleAuthor = new SimpleAuthorizationInfo();
         System.out.println(simpleAuthor.getRoles());
         simpleAuthor.setRoles((Set<String>) account.getRoles());
         simpleAuthor.setObjectPermissions((Set<Permission>) account.getObjectPermissions());
         return simpleAuthor;
     }
 }

测试代码

package cn.chendd.shiro.examples.login;
 
 import ...;
 
 /**
  * @author chendd
  * 自定义登录验证器（模拟从数据库中获取账号登录）
  */
 public class LoginRealmTest extends LoginTest {
 
     @Test
     public void testLoginRealm() {
         logger.info("###测试自定义认证器登录--用户名 {} ，密码 {} ###" , username , password);
         String resourcePath = "classpath:shiro/shiro-loginRealm.ini";
         Realm realm = new LoginRealm(resourcePath);
         SecurityManager securityManager = new DefaultSecurityManager(realm);
         SecurityUtils.setSecurityManager(securityManager);
         Subject subject = SecurityUtils.getSubject();
         UsernamePasswordToken token = new UsernamePasswordToken(username, password);
         try {
             Subject loginSubject = securityManager.login(subject, token);
             if (loginSubject.isAuthenticated()) {
                 logger.debug("用户已经认证");
             }
             logger.info("用户名 {} 认证成功", loginSubject.getPrincipal());
             logger.info("是否拥有角色manager：{}", loginSubject.hasRole("manager"));
             logger.info("是否拥有联系人查询权限：{}", loginSubject.isPermitted("concat:select"));
 
         } catch (AuthenticationException e) {
             logger.error("用户名 {} 认证失败", username, e);
         }
     }
 
 }

运行结果

另外的一个自定义认证

package cn.chendd.shiro.custom;
 
import ...
 
 /**
  * 自定义用户、角色、权限认证器
  * @author chendd
  */
 public class PrimisionRealm extends IniRealm {
 
     Logger logger = LoggerFactory.getLogger(this.getClass());
 
     @Override
     public String getName() {
         return "chendd-primision-realm";
     }
 
     //授权
     @Override
     protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
         SimpleAuthorizationInfo author = new SimpleAuthorizationInfo();
         String userName = (String) principals.getPrimaryPrincipal();
         logger.debug("###构造用户[{}]的角色权限授权信息###" , userName);
         Set<String> roles = new HashSet<>();//角色集合
         Set<String> primisions = new HashSet<>();//权限集合
         if("admin".equals(userName)){
             roles.add("admin");//管理员角色，任意权限
             primisions.add("*");
         } else if("chendd".equals(userName)){
             roles.add("coder");//coder角色及权限
             primisions.add("usermanager:*");
             primisions.add("logmanager:select");
             primisions.add("menumanager:insert");
             primisions.add("menumanager:delete");
             roles.add("tester");//tester角色及权限
             primisions.add("menumanager:test:test");
             primisions.add("menumanager:insert");
         } else if("tt".equals(userName)){
             roles.add("tester");//tester角色及权限
             primisions.add("menumanager:test:test");
             primisions.add("menumanager:insert");
         } else {
             throw new AuthenticationException("用户名与密码不匹配！");
         }
         author.addRoles(roles);
         author.addStringPermissions(primisions);
         return author;
     }
 
     //认证
     @Override
     protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
 
         UsernamePasswordToken userToken = (UsernamePasswordToken) token;
         String userName = userToken.getUsername();
         String password = new String(userToken.getPassword());
         boolean flag = false;
         if("admin".equals(userName) && "admin123".equals(password)){
             flag = true;
         } else if("chendd".equals(userName) && "chendd123".equals(password)){
             flag = true;
         } else if("tt".equals(userName) && "tt123".equals(password)){
             flag = true;
         } else {
             throw new AuthenticationException("用户名与密码不匹配！");
         }
         AuthenticationInfo authent = new SimpleAuthenticationInfo(token.getPrincipal() , token.getCredentials() , this.getName());
         return authent;
     }
 }
