SpringBoot整合Shiro

1导入依赖

<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring</artifactId>
    <version>1.4.0</version>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
</dependency>

<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.1.2</version>
</dependency>

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.1.10</version>
</dependency>

2配置application.properties

#配置mysql
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.url=jdbc:mysql:///java2002?serverTimezone=Asia/Shanghai
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
#连接池
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

#扫描mapper.xml文件
mybatis.mapper-locations=classpath:mapper/*.xml
#sql语句显示到控制台
mybatis.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl

#配置thymeleaf
spring.thymeleaf.prefix=classpath:/templates
spring.thymeleaf.suffix=.html
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.cache=false
spring.thymeleaf.mode=HTML

3编写ShiroRealm

package com.qf.realm;

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;

public class ShiroRealm extends AuthorizingRealm {
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        return null;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        return null;
    }
}

4编写ShiroConfig

package com.qf.config;

import at.pollux.thymeleaf.shiro.dialect.ShiroDialect;
import com.qf.realm.ShiroRealm;
import org.apache.shiro.mgt.DefaultSecurityManager;
import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.CookieRememberMeManager;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.apache.shiro.web.servlet.SimpleCookie;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.LinkedHashMap;

@Configuration
public class ShiroConfig {

    public ShiroRealm getShiroRealm(){
        return new ShiroRealm();
    }

    //安全管理对象
    @Bean
    public SecurityManager getSecurityManager(){
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(getShiroRealm());
        return securityManager;
    }


    //Shiro过滤器配置
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(SecurityManager securityManager){
        //创建Shiro工厂对象
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //设置安全管理器
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        //未认证访问页面
        shiroFilterFactoryBean.setLoginUrl("/toLogin");
        //认证成功跳转页面（一般不设置，默认登录成功跳转当前页面）
        //shiroFilterFactoryBean.setSuccessUrl("/index");
        //未授权访问页面
        shiroFilterFactoryBean.setUnauthorizedUrl("/refuse");
        //通过map配置访问流程（顺序很重要）
        LinkedHashMap<String, String> map = new LinkedHashMap<>();
        //配置静态资源
        map.put("/js/**","anon");
        map.put("/css/**","anon");
        map.put("/jquery/**","anon");
        map.put("/layui/**","anon");
        //配置login页面
        map.put("/login","anon");
        //配置logout退出
        //map.put("/logout","logout");
        //配置授权
        //map.put("/delete","perms[user:delete]");
        //map.put("/select","perms[user:select]");

        //user设置记住我（二次登录不做认证操作）
        //map.put("/index","user");

        map.put("/**","authc");//该路径认证后才能访问
        //map.put("/**","anon");//所有路径都可以匿名访问

        shiroFilterFactoryBean.setFilterChainDefinitionMap(map);
        return shiroFilterFactoryBean;
    }

}

anon：admins/**=anon 没有参数，表示可以匿名使用。
authc：/admins/user/**=authc表示需要认证(登录)才能使用，FormAuthenticationFilter是表单认证，没有参数 

roles：/admins/user/**=roles[admin],参数可以写多个，多个时必须加上引号，并且参数之间用逗号分割，当有多个参数时，例如admins/user/**=roles["admin,guest"],每个参数通过才算通过，相当于hasAllRoles()方法。

perms：/admins/user/**=perms[user:add:*],参数可以写多个，多个时必须加上引号，并且参数之间用逗号分割，例如/admins/user/**=perms["user:add:*,user:modify:*"]，当有多个参数时必须每个参数都通过才通过，想当于isPermitedAll()方法。

rest：/admins/user/**=rest[user],根据请求的方法，相当于/admins/user/**=perms[user:method] ,其中method为post，get，delete等。

port：/admins/user/**=port[8081],当请求的url的端口不是8081是跳转到schemal：//serverName:8081?queryString,其中schmal是协议http或https等，serverName是你访问的host,8081是url配置里port的端口，queryString是你访问的url里的？后面的参数。

authcBasic：例如/admins/user/**=authcBasic没有参数表示httpBasic认证

ssl：/admins/user/**=ssl没有参数，表示安全的url请求，协议为https

user：/admins/user/**=user没有参数表示必须存在用户, 身份认证通过或通过记住我认证通过的可以访问，当登入操作时不做检查

5创建controller

package com.qf.controller;


import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.IncorrectCredentialsException;
import org.apache.shiro.authc.UnknownAccountException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class UserController {

    @RequestMapping("toLogin")
    public String toLgoin(){
        System.out.println("toLogin");
        return "/login";
    }

    @RequestMapping("login")
    public String login(){
        System.out.println("login");
        return "/login";
    }

    @RequestMapping("refuse")
    public String refuse(){
        System.out.println("refuse");
        return "/refuse";
    }

    @RequestMapping("index")
    public String index(){
        System.out.println("index");
        return "/index";
    }

    @RequestMapping("add")
    public String add(){
        System.out.println("add");
        return "/add";
    }

    @RequestMapping("select")
    public String select(){
        System.out.println("select");
        return "/select";
    }

    @RequestMapping("delete")
    public String delete(){
        System.out.println("delete");
        return "/delete";
    }

//    @RequestMapping("logout")
//    public String logout(){
//        System.out.println("logout");
//        Subject subject = SecurityUtils.getSubject();
//        subject.logout();
//        return "/login";
//    }
}

6编写对应的login.html页面（以及其他页面）

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>

<center>
    <form action="login">

        用户名：<input type="text" name="username"><br> <br>
        密码：<input type="password" name="password"><br> <br>

        <input type="submit" value="登录">
    </form>
</center>

</body>
</html>

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h1><font color="red">拒绝访问！！！</font> </h1>
</body>
</html>

<!DOCTYPE html>
<html lang="en" xmlns:shiro="http://www.w3.org/1999/xhtml">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>

<h1>主页面</h1>

<a href="add">添加用户</a>
<a href="select">查询用户</a>
<a href="delete">删除用户</a>
<a href="update">修改用户</a>
<a href="/logout">退出</a>

</body>
</html>

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h1>添加用户</h1>
</body>
</html>

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h1>查询用户</h1>
</body>
</html>

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h1>删除用户</h1>
</body>
</html>

7实现用户认证，修改UserController中的login方法

@RequestMapping("login")
public String login(String username, String password){
    System.out.println("login");

    Subject subject = SecurityUtils.getSubject();

    UsernamePasswordToken token = new UsernamePasswordToken(username, password);

    subject.login(token);

    boolean authenticated = subject.isAuthenticated();

    if(authenticated){
        return "/index";
    }
    return "/login";
}

8修改ShiroRealm中的AuthenticationInfo方法

@Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {

        //身份信息，用户名
        String principal = (String)token.getPrincipal();
        System.out.println(principal);
        //凭证信息，密码
        String credentials = new String((char[])token.getCredentials());
        System.out.println(credentials);

        //判断
        if("jack".equals(principal) && "123".equals(credentials)){
            return new SimpleAuthenticationInfo(principal,credentials,"ShiroRealm");
        }

        return null;
    }

9实现用户授权，在ShiroConfig中的shiroFilter方法中添加被授权的信息

//配置授权
map.put("/delete","perms[user:delete]");
map.put("/select","perms[user:select]");

10修改ShiroRealm中的doGetAuthorizationInfo方法

@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {

    SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();

    HashSet<String> set = new HashSet<>();
    set.add("user:select");
    set.add("user:update");

    simpleAuthorizationInfo.addStringPermissions(set);

    return simpleAuthorizationInfo;
}

11Shiro整合thymleaf标签

<dependency>
    <groupId>com.github.theborakompanioni</groupId>
    <artifactId>thymeleaf-extras-shiro</artifactId>
    <version>2.0.0</version>
</dependency>

12在ShiroConfig中添加该方法

@Bean
public ShiroDialect getShiroDialect(){
    return new ShiroDialect();
}

13修改index.html页面中测试

<!DOCTYPE html>
<html lang="en" xmlns:shiro="http://www.w3.org/1999/xhtml">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>

<h1>主页面</h1>

<a href="add">添加用户</a>
<a href="select">查询用户</a>
<a href="delete" shiro:hasPermission="user:delete">删除用户</a>
<a href="update" shiro:hasPermission="user:update">修改用户</a>
<a href="/logout">退出</a>

</body>
</html>

14实现用户退出（两种方式），在相关index.html页面中添加超链接

<a href="/logout">退出</a>

15在ShiroConfig中的shiroFilter方法中添加退出配置（第一种）

//配置退出
map.put("/logout","logout");

16在UserController中添加logout方法（第二种）

@RequestMapping("logout")
public String logout(){
    System.out.println("logout");
    Subject subject = SecurityUtils.getSubject();
    subject.logout();
    return "/login";
}

17记住我rememberMe，在login.html页面中添加记住我

<input type="checkbox" name="rememberMe">记住我<br> <br>

18在UserController中的login方法配置rememberMe参数

@RequestMapping("login")
public String login(String username, String password,boolean rememberMe){
    System.out.println("login");

    Subject subject = SecurityUtils.getSubject();

    UsernamePasswordToken token = new UsernamePasswordToken(username, password,rememberMe);

    subject.login(token);

    boolean authenticated = subject.isAuthenticated();

    if(authenticated){
        return "/index";
    }
    return "/login";
}

19在ShiroConfig类中添加相关方法以及代码

package com.qf.config;

import at.pollux.thymeleaf.shiro.dialect.ShiroDialect;
import com.qf.realm.ShiroRealm;
import org.apache.shiro.mgt.DefaultSecurityManager;
import org.apache.shiro.mgt.SecurityManager;

import org.apache.shiro.web.mgt.CookieRememberMeManager;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.apache.shiro.web.servlet.SimpleCookie;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.LinkedHashMap;

@Configuration
public class ShiroConfig {

    @Bean
    public CookieRememberMeManager getCookieRememberMeManager(){

        SimpleCookie simpleCookie = new SimpleCookie("renemberMe");
        simpleCookie.setMaxAge(3600*24*31);

        CookieRememberMeManager cookieRememberMeManager = new CookieRememberMeManager();
        cookieRememberMeManager.setCookie(simpleCookie);

        return cookieRememberMeManager;
    }

    public ShiroRealm getShiroRealm(){
        return new ShiroRealm();
    }

    @Bean
    public SecurityManager getSecurityManager(){
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(getShiroRealm());
        securityManager.setRememberMeManager(getCookieRememberMeManager());
        return securityManager;
    }

    //配置ShiroDialect
    @Bean
    public ShiroDialect getShiroDialect(){
        return new ShiroDialect();
    }

    //shiro过滤器配置
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(SecurityManager securityManager){
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        //未认证访问页面
        shiroFilterFactoryBean.setLoginUrl("/toLogin");
        //认证成功跳转页面（一般不设置，默认登录成功跳转当前页面）
        //shiroFilterFactoryBean.setSuccessUrl("/index");
        //未授权访问页面
        shiroFilterFactoryBean.setUnauthorizedUrl("/refuse");
        //通过map配置访问流程（顺序很重要）
        LinkedHashMap<String, String> map = new LinkedHashMap<>();
        //配置静态资源
        map.put("/js/**","anon");
        map.put("/css/**","anon");
        map.put("/jquery/**","anon");
        map.put("/layui/**","anon");
        //配置login页面
        map.put("/login","anon");
        //配置logout退出
        map.put("/logout","logout");
        //配置授权
        map.put("/delete","perms[user:delete]");
        map.put("/select","perms[user:select]");

        //user设置记住我（二次登录不做认证操作）
        map.put("/index","user");

        map.put("/**","authc");//该路径认证后才能访问
        //map.put("/**","anon");//所有路径都可以匿名访问

        shiroFilterFactoryBean.setFilterChainDefinitionMap(map);
        return shiroFilterFactoryBean;
    }
