Controller

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class MyController {
    @RequestMapping({"/", "/index"})
    public String toIndex(Model model) {
        model.addAttribute("msg", "hello Shiro");
        return "index";
    }

    @RequestMapping("/user/add")
    public String add(){
        return "user/add";
    }
    @RequestMapping("/user/update")
    public String update(){
        return "user/update";
    }
    @RequestMapping("/toLogin")
    public String toLogin() {
        return "login";
    }
}

shiro配置類

import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class ShiroConfig {

    //3、ShiroFilterFactoryBean，在容器中通過@Qualifier註解將securityManager傳遞過來，
    //這裏有一個坑，一定要在Bean註解添加name屬性，否則報錯找不到shiroFilterFactoryBean
    @Bean(name = "shiroFilterFactoryBean")
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //設置安全管理器
        shiroFilterFactoryBean.setSecurityManager(defaultWebSecurityManager);
        return shiroFilterFactoryBean;
    }

    //2、DefaultWebSecurityManager,在容器中通過@Qualifier註解將UserRealm傳遞過來，
    @Bean(name = "securityManager")
    public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        //關聯UserRealm
        securityManager.setRealm(userRealm);
        return securityManager;
    }

    //1、創建realm對象，需自定義類
    @Bean(name = "userRealm")
    public UserRealm userRealm(){
        return new UserRealm();
    }
}

自定義的Realm對象

import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
//自定義realm
public class UserRealm extends AuthorizingRealm {
    //授權
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("執行了授權");
        return null;
    }
    //認證
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        System.out.println("執行了認證");
        return null;
    }
}

啓動點擊對於的a標籤即可實現跳轉，因爲還沒使用過濾，所有可以訪問所有頁面

實現登錄攔截

在getShiroFilterFactoryBean方法內添加shiro內置過濾器

 //3、ShiroFilterFactoryBean，在容器中通過@Qualifier註解將securityManager傳遞過來，
    //這裏有一個坑，一定要在Bean註解添加name屬性，否則報錯找不到shiroFilterFactoryBean
    @Bean(name = "shiroFilterFactoryBean")
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //設置安全管理器
        shiroFilterFactoryBean.setSecurityManager(defaultWebSecurityManager);
        //添加shiro內置過濾器
        /*
            anon:無需認證即可訪問
            authc:必須認證了才能訪問
            user:必須擁有 記住我 功能才能訪問
            perms:擁有對某個資源權限才能訪問
            role:擁有某個角色權限才能訪問
        */
        //攔截
        Map<String, String> filterMap=new LinkedHashMap<>();
        //user下所有的頁面都需要認證才能訪問
        filterMap.put("/user/*","authc");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterMap);
        //設置登錄請求
        shiroFilterFactoryBean.setLoginUrl("/toLogin");
        return shiroFilterFactoryBean;
    }

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<p th:text="${msg}" style="color: red"></p>
<form th:action="@{/login}">
    <p>用戶名：<input type="text" name="username"></p>
    <p>密碼：<input type="password" name="password"></p>
    <p><input type="submit"></p>
</form>
</body>
</html>

此時點擊add或者update會跳轉到login頁面

實現用戶認證

Controller加入

  @RequestMapping("/login")
    public String login(String username, String password, Model model) {
        //獲取當前的用戶
        Subject subject = SecurityUtils.getSubject();
        //封裝用戶登錄的數據
        UsernamePasswordToken token = new UsernamePasswordToken(username, password);
        try {
            //執行登錄方法，沒有異常就代表登錄上了
            subject.login(token);
            return "index";
        } catch (UnknownAccountException e) {//用戶名不存在報錯
            model.addAttribute("msg", "用戶名錯誤");
            return "login";
        } catch (IncorrectCredentialsException e) {
            model.addAttribute("msg", "密碼錯誤");
            return "login";
        }
    }

UserRealm加入

  //認證
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        System.out.println("執行了認證");
        //數據庫賬戶密碼
        String name="root";
        String password="123456";
        UsernamePasswordToken userToken=(UsernamePasswordToken)token;
        if(!userToken.getUsername().equals(name)){
            return null;//如果沒有匹配到返回null會拋出異常
        }
        //密碼認證，shiro做
        return new SimpleAuthenticationInfo("", password, "");
    }

整合Mybatis

application.properties，mybatis配置文件

mybatis.type-aliases-package=com.ykk.pojo
mybatis.mapper-locations=classpath:mapper/*.xml

application.yml

spring:

User實體類

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
    private int id;
    private String name;
    private String pwd;
}

UserMapper

@Repository
@Mapper
public interface UserMapper {
    User queryUserByName(String name);
}

UserMapper.XML(要放到resource下，不然會找不到資源)

<?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.ykk.mapper.UserMapper">
    <select id="queryUserByName" parameterType="String" resultType="User">
       select * from User where name = #{name};
    </select>
</mapper>

UserService

public interface UserService {
    public User queryUserByName(String name);
}

UserServiceImpl

@Service
public class UserServiceImpl implements UserService{
    @Autowired
    UserMapper userMapper;

    @Override
    public User queryUserByName(String name) {
        return userMapper.queryUserByName(name);
    }
}

修改自定義的UserRealm中認證方法

    //認證
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        System.out.println("執行了認證");
        UsernamePasswordToken userToken=(UsernamePasswordToken)token;
        //連接真實數據庫，通過@Autowired注入userService
        User user = userService.queryUserByName(userToken.getUsername());
        if(user==null){//沒有這個用戶
            return null;
        }
        //密碼認證，shiro做
        return new SimpleAuthenticationInfo("", user.getPwd(), "");
    }

實現請求授權

數據庫加入perms字段

//自定義realm
public class UserRealm extends AuthorizingRealm {
    @Autowired
    UserServiceImpl userService;

    //授權
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("執行了授權");
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
        //添加權限，一般從數據庫表獲取，這裏是寫死了
        //info.addStringPermission("user:add");
        //拿到當前登錄的對象
        Subject subject = SecurityUtils.getSubject();
        User currentUser = (User) subject.getPrincipal();
        //設置當前用戶權限
        info.addStringPermission(currentUser.getPerms());
        return info;
    }

    //認證
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        System.out.println("執行了認證");
        UsernamePasswordToken userToken = (UsernamePasswordToken) token;
        //連接真實數據庫
        User user = userService.queryUserByName(userToken.getUsername());
        if (user == null) {//沒有這個用戶
            return null;
        }
        //密碼認證，shiro做。這裏傳過去的user在doGetAuthorizationInfo方法可以拿到
        return new SimpleAuthenticationInfo(user, user.getPwd(), "");
    }
}

    //3、ShiroFilterFactoryBean，在容器中通過@Qualifier註解將securityManager傳遞過來，
    //這裏有一個坑，一定要在Bean註解添加name屬性，否則報錯找不到shiroFilterFactoryBean
    @Bean(name = "shiroFilterFactoryBean")
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //設置安全管理器
        shiroFilterFactoryBean.setSecurityManager(defaultWebSecurityManager);
        //添加shiro內置過濾器
        /*
            anon:無需認證即可訪問
            authc:必須認證了才能訪問
            user:必須擁有 記住我 功能才能訪問
            perms:擁有對某個資源權限才能訪問
            role:擁有某個角色權限才能訪問
        */
        //攔截
        Map<String, String> filterMap=new LinkedHashMap<>();

        //授權，沒授權會轉到對於的頁面
        filterMap.put("/user/add","perms[user:add]");
        filterMap.put("/user/update","perms[user:update]");
        //user目錄下的頁面需要驗證才能訪問
        filterMap.put("/user/*","authc");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterMap);
        //設置登錄請求
        shiroFilterFactoryBean.setLoginUrl("/toLogin");
        return shiroFilterFactoryBean;
    }
