关于 Apache Shiro 概念基本都粘自官网 http://shiro.apache.org/
Apache Shiro是一个功能强大且灵活的开源安全框架,可以清晰地处理身份验证,授权,企业会话管理和加密。
以下是Apache Shiro可以做的一些事情:
可以参考官方文档: http://shiro.apache.org/archi...
缓存架包先用 ehcache
<dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-all</artifactId> <version>1.3.2</version> </dependency> <dependency> <groupId>net.sf.ehcache</groupId> <artifactId>ehcache</artifactId> <version>2.10.6</version> </dependency>
<?xml version="1.0" encoding="UTF-8"?> <ehcache> <!-- mac 电脑, 跟 win 设置路径有点不一样 示例: path="d:/ehcache/" --> <diskStore path="${user.home}/Downloads/ehcache" /> <!-- 默认缓存配置 没有特别指定就用这个配置 --> <defaultCache maxElementsInMemory="10000" eternal="false" timeToIdleSeconds="3600" timeToLiveSeconds="3600" overflowToDisk="true" maxElementsOnDisk="10000000" diskPersistent="false" memoryStoreEvictionPolicy="LRU" diskExpiryThreadIntervalSeconds="120" /> </ehcache>
<!-- 1. 配置 shiro 拦截器 --> <filter> <filter-name>shiroFilter</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> <init-param> <param-name>targetFilterLifecycle</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>shiroFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
<!-- 2. 配置shiro的核心组件 SecurityManager --> <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"> <!-- 配置缓存 --> <property name="cacheManager" ref="cacheManager" /> <property name="realm" ref="realm" /> </bean> <bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager"> <property name="cacheManagerConfigFile" value="classpath:ehcache.xml"></property> </bean> <bean id="realm" class="com.ogemray.shiro.MyShiroRealm"> <property name="credentialsMatcher"> <bean class="com.ogemray.shiro.MyCredentialsMatcher"></bean> </property> </bean> <!-- 3. 配置shiroFilter,配置shiro的一些基本规则信息,id必须和web.xml中配置的拦截器名字一样(DelegatingFilterProxy 通过名字去spring容器中找注入的拦截器) --> <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <property name="securityManager" ref="securityManager"/> <property name="loginUrl" value="/login.html"/> <!-- loginUrl 表示登录页面地址 --> <property name="successUrl" value="/admin/main.html"/> <!-- successUrl 表示登录成功后跳转的页面 --> <property name="unauthorizedUrl" value="/unauthorized.html"></property> <!-- 配置没有授权跳转页面 --> <property name="filterChainDefinitions"> <value> <!--/logout.action=logout --> <!-- logout 表示登出, 清空session, 这里不需要了, 因为已经在登出对象的方法里手动清空了 [ SecurityUtils.getSubject().logout() ] --> /admin/userlist*=roles[user] /admin/adduser*=roles["user,admin"] <!-- 表示拥有 user 角色 并且 拥有 admin 角色 --> /admin/editRPRelation*=roles[admin],perms[user:insert,user:update,user:select,user:delete] /admin/editURRelation*=perms[user:select] /admin/**=authc /**=anon </value> </property> </bean>
public class MyShiroRealm extends AuthorizingRealm { @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException { System.out.println("********************* 进行登录认证 *********************"); String username = (String) authenticationToken.getPrincipal(); //获取提交的用户名 User user = userRepository.findByUsername(username); if (user == null) throw new UnknownAccountException("用户不存在, 请先注册然后再来登录"); if (user.getState() == 1) throw new LockedAccountException("该用户已经被管理员禁用, 请换个账号登录"); //接下来进行密码的比对 SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user, user.getPassword(), getName()); return info; } @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { System.out.println("********************* 进行授权认证 *********************"); User user = (User) principalCollection.asList().get(0); Set<String> roles = new HashSet<>(); Set<String> permissions = new HashSet<>(); user.getRoles().forEach(role -> { roles.add(role.getRoleName()); role.getPermissions().forEach(permission -> { permissions.add(permission.getPermissionName()); }); }); SimpleAuthorizationInfo info = new SimpleAuthorizationInfo(); info.setRoles(roles); info.setStringPermissions(permissions); return info; } @Autowired private UserRepository userRepository; }
前端密码加密规则:ciphertext_pwd = AES.encrypt(MD5(password))
后端解密密码规则:md5_password = AES.desEncrypt(ciphertext_pwd)
后端匹对密码规则:(md5_password + 用户名做盐值) 进行 1024 次 MD5 转换,然后与数据库取出密码做比对
public class MyCredentialsMatcher implements CredentialsMatcher { @Override public boolean doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) { String tokenCredentials = Arrays.toString((char[]) token.getCredentials()); //前端传过来的密码 String accountCredentials = (String) info.getCredentials(); //数据库查询到的密码 //首先对前端传过来的密码进行AES解密 -> 清空 session 里面的key Session session = SecurityUtils.getSubject().getSession(); String key = (String) session.getAttribute("AESKey"); try { tokenCredentials = AesEncryptUtil.desEncrypt(tokenCredentials, key, key); } catch (Exception e) { throw new IncorrectCredentialsException("可能受到重放攻击, AES 解密失败"); } session.removeAttribute("AESKey"); //加密方式 待加密数据 加密盐值 加密次数 SimpleHash simpleHash = new SimpleHash("MD5", tokenCredentials, token.getPrincipal(), 1024); return simpleHash.toString().equals(accountCredentials); } }
@Service("userService") public class UserServiceImpl implements UserService { @Override public void registerUser(User user) { if (userRepository.existsByUsername(user.getUsername())) { throw new RuntimeException("用户名已经被注册, 请换个用户名"); } user.setState((byte) 0); //密码进行加密 SimpleHash simpleHash = new SimpleHash("MD5", user.getPassword(), user.getUsername(), 1024); user.setPassword(simpleHash.toString()); userRepository.save(user); } @Override public void login(User user) { Subject currentUser = SecurityUtils.getSubject(); if (currentUser.isAuthenticated() == false) { //没有登录过需要进行登录验证 UsernamePasswordToken token = new UsernamePasswordToken(user.getUsername(), user.getPassword(), false); currentUser.login(token); } } @Autowired private UserRepository userRepository; }
