7.ShiroConfig.java
@Configuration public class ShiroConfig { //ShiroFilterFactoryBean (第三步:连接到前端) @Bean public ShiroFilterFactoryBean getShiroFilterBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){ ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean(); //设置安全管理器 bean.setSecurityManager(defaultWebSecurityManager); //添加shiro的内置过滤器 /* anon: 无需认证即可访问 authc: 必须认证才能用 user: 必须拥有 “记住我” 功能才能用 perms: 拥有对某个资源的权限才能用 role: 拥有某个角色权限才能访问 */ Map<String,String> filterMap = new LinkedHashMap<>(); //拦截 filterMap.put("/user/add","authc"); filterMap.put("/user/update","authc"); //也可使用通配符* //filterMap.put("/user/*","authc"); //授权,正常情况下没有授权会跳转到未授权页面 filterMap.put("/user/add","perms[user:add]"); filterMap.put("/user/update","perms[user:update]"); bean.setFilterChainDefinitionMap(filterMap); //若访问时用户未认证,则跳转至登录页面 bean.setLoginUrl("/toLogin"); //若访问时用户未被授权,则跳转至未授权页面 bean.setUnauthorizedUrl("/noauth"); return bean; } //DefaultWebSecurityManager (第二步:管理realm对象) @Bean(name="securityManager") //@Bean注解后便被spring托管,不加name属性,默认name值为方法名,这里就加一下吧 public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){ DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager(); //关联UserRealm securityManager.setRealm(userRealm); return securityManager; } //创建realm对象,需要自定义类 (第一步:创建realm对象) @Bean(name="userRealm") //@Bean注解后便被spring托管,不加name属性,默认name值为方法名,这里就加一下吧 public UserRealm userRealm(){ return new UserRealm(); } //整合ShiroDialect:用来整合shiro thymeleaf @Bean public ShiroDialect getShiroDialect(){ return new ShiroDialect(); } }
8.UserRealm.java
//自定义UserRealm extends AuthorizingRealm public class UserRealm extends AuthorizingRealm { @Autowired UserService userService; //授权 @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) { System.out.println("执行了授权"); SimpleAuthorizationInfo info = new SimpleAuthorizationInfo(); //info.addStringPermission("user:add"); //拿到当前登录的对象 Subject subject = SecurityUtils.getSubject(); User currentUser = (User) subject.getPrincipal(); //拿到user对象 info.addStringPermission(currentUser.getPerms()); return info; } //认证 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { System.out.println("执行了认证"); UsernamePasswordToken userToken = (UsernamePasswordToken) token; /* //用户名、密码 模拟从数据库中获取 String name = "root"; String password = "1111"; if (!userToken.getUsername().equals(name)){ return null; //抛出异常 UnknownAccountException } //密码认证,shiro做~ return new SimpleAuthenticationInfo("",password,""); */ //连接真实数据库 User user = userService.queryUserByName(userToken.getUsername()); if (user==null){ //没有这个人 return null; //抛出异常 UnknownAccountException } Subject currentSubject = SecurityUtils.getSubject(); Session session = currentSubject.getSession(); session.setAttribute("loginUser",user); //可以加密: MD5加密 MD5盐值加密 //密码认证,shiro做~ return new SimpleAuthenticationInfo(user,user.getPwd(),""); } }
9.UserMapper.java
@Repository @Mapper public interface UserMapper { public User queryUserByName(String name); }
10.UserMapper.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.ztx.mapper.UserMapper"> <select id="queryUserByName" parameterType="String" resultType="User"> select * from mybatis.user where name=#{name} </select> </mapper>
11.User.java
@Data @AllArgsConstructor @NoArgsConstructor public class User { private int id; private String name; private String pwd; private String perms; }
12.UserService.java和UserServiceImpl.java
public interface UserService { public User queryUserByName(String name); } ----------------------------------------------------- @Service public class UserServiceImpl implements UserService{ @Autowired UserMapper userMapper; @Override public User queryUserByName(String name) { return userMapper.queryUserByName(name); } }
13.数据库中的user表
个人对该项目执行流程进行了梳理,如有错误,请指正:
1.ShiroConf.java中设置好拦截器,规定哪些页面需要用户具备何种要求才可访问,同时还设置当用户不满足要求时应该跳转至什么页面。对应本项目的代码:
2.用户在未认证下,会跳转到登陆页面login.html。输入用户名密码,提交执行controller中的login()方法,该方法内将用户信息封装成token对象,传入subject.login()方法内进行登录验证。对应项目代码:
3.执行登录验证时会跳转到UserRealm类,首先执行认证(doGetAuthenticationInfo):连接数据库判断是否有此人,若没有则返回结果null,若有,则将数据库中的用户信息存储在subject的session中。接着进行密码验证,若验证失败,则将登录不通过返回失败认证信息,反之,返回成功的认证信息,并执行用户授权(doGetAuthorizationInfo)操作,返回授权信息。对应项目代码:
认证:
授权:
4.本项目中登录成功后跳转到index.html时依旧会再次执行授权操作,因为前端页面需要一个判断展示功能,代码如下:
故控制台信息会是这样:(出现两次授权)
5.之后进入add.html或update.html时,因为会被拦截,所以都要进行授权验证,而此时认证将不会在执行。
