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配置类

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，在容器中通过@Qualifier注解将securityManager传递过来，
    //这里有一个坑，一定要在Bean注解添加name属性，否则报错找不到shiroFilterFactoryBean
    @Bean(name = "shiroFilterFactoryBean")
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //设置安全管理器
        shiroFilterFactoryBean.setSecurityManager(defaultWebSecurityManager);
        return shiroFilterFactoryBean;
    }

    //2、DefaultWebSecurityManager,在容器中通过@Qualifier注解将UserRealm传递过来，
    @Bean(name = "securityManager")
    public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        //关联UserRealm
        securityManager.setRealm(userRealm);
        return securityManager;
    }

    //1、创建realm对象，需自定义类
    @Bean(name = "userRealm")
    public UserRealm userRealm(){
        return new UserRealm();
    }
}

自定义的Realm对象

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;
//自定义realm
public class UserRealm extends AuthorizingRealm {
    //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("执行了授权");
        return null;
    }
    //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        System.out.println("执行了认证");
        return null;
    }
}

启动点击对于的a标签即可实现跳转，因为还没使用过滤，所有可以访问所有页面

实现登录拦截

在getShiroFilterFactoryBean方法内添加shiro内置过滤器

 //3、ShiroFilterFactoryBean，在容器中通过@Qualifier注解将securityManager传递过来，
    //这里有一个坑，一定要在Bean注解添加name属性，否则报错找不到shiroFilterFactoryBean
    @Bean(name = "shiroFilterFactoryBean")
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //设置安全管理器
        shiroFilterFactoryBean.setSecurityManager(defaultWebSecurityManager);
        //添加shiro内置过滤器
        /*
            anon:无需认证即可访问
            authc:必须认证了才能访问
            user:必须拥有 记住我 功能才能访问
            perms:拥有对某个资源权限才能访问
            role:拥有某个角色权限才能访问
        */
        //拦截
        Map<String, String> filterMap=new LinkedHashMap<>();
        //user下所有的页面都需要认证才能访问
        filterMap.put("/user/*","authc");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterMap);
        //设置登录请求
        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>用户名：<input type="text" name="username"></p>
    <p>密码：<input type="password" name="password"></p>
    <p><input type="submit"></p>
</form>
</body>
</html>

此时点击add或者update会跳转到login页面

实现用户认证

Controller加入

  @RequestMapping("/login")
    public String login(String username, String password, Model model) {
        //获取当前的用户
        Subject subject = SecurityUtils.getSubject();
        //封装用户登录的数据
        UsernamePasswordToken token = new UsernamePasswordToken(username, password);
        try {
            //执行登录方法，没有异常就代表登录上了
            subject.login(token);
            return "index";
        } catch (UnknownAccountException e) {//用户名不存在报错
            model.addAttribute("msg", "用户名错误");
            return "login";
        } catch (IncorrectCredentialsException e) {
            model.addAttribute("msg", "密码错误");
            return "login";
        }
    }

UserRealm加入

  //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        System.out.println("执行了认证");
        //数据库账户密码
        String name="root";
        String password="123456";
        UsernamePasswordToken userToken=(UsernamePasswordToken)token;
        if(!userToken.getUsername().equals(name)){
            return null;//如果没有匹配到返回null会抛出异常
        }
        //密码认证，shiro做
        return new SimpleAuthenticationInfo("", password, "");
    }

整合Mybatis

        </dependency>

application.properties，mybatis配置文件

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

application.yml

spring:
  datasource:
    username: root
    password: root
    #?serverTimezone=UTC解决时区的报错

User实体类

@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，不然会找不到资源)

<?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);
    }
}

修改自定义的UserRealm中认证方法

    //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        System.out.println("执行了认证");
        UsernamePasswordToken userToken=(UsernamePasswordToken)token;
        //连接真实数据库，通过@Autowired注入userService
        User user = userService.queryUserByName(userToken.getUsername());
        if(user==null){//没有这个用户
            return null;
        }
        //密码认证，shiro做
        return new SimpleAuthenticationInfo("", user.getPwd(), "");
    }

实现请求授权

数据库加入perms字段

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

    //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("执行了授权");
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
        //添加权限，一般从数据库表获取，这里是写死了
        //info.addStringPermission("user:add");
        //拿到当前登录的对象
        Subject subject = SecurityUtils.getSubject();
        User currentUser = (User) subject.getPrincipal();
        //设置当前用户权限
        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;
        //连接真实数据库
        User user = userService.queryUserByName(userToken.getUsername());
        if (user == null) {//没有这个用户
            return null;
        }
        //密码认证，shiro做。这里传过去的user在doGetAuthorizationInfo方法可以拿到
        return new SimpleAuthenticationInfo(user, user.getPwd(), "");
    }
}

    //3、ShiroFilterFactoryBean，在容器中通过@Qualifier注解将securityManager传递过来，
    //这里有一个坑，一定要在Bean注解添加name属性，否则报错找不到shiroFilterFactoryBean
    @Bean(name = "shiroFilterFactoryBean")
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //设置安全管理器
        shiroFilterFactoryBean.setSecurityManager(defaultWebSecurityManager);
        //添加shiro内置过滤器
        /*
            anon:无需认证即可访问
            authc:必须认证了才能访问
            user:必须拥有 记住我 功能才能访问
            perms:拥有对某个资源权限才能访问
            role:拥有某个角色权限才能访问
        */
        //拦截
        Map<String, String> filterMap=new LinkedHashMap<>();

        //授权，没授权会转到对于的页面
        filterMap.put("/user/add","perms[user:add]");
        filterMap.put("/user/update","perms[user:update]");
        //user目录下的页面需要验证才能访问
        filterMap.put("/user/*","authc");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterMap);
        //设置登录请求
        shiroFilterFactoryBean.setLoginUrl("/toLogin");
        return shiroFilterFactoryBean;
    }

整合thymeleaf
