SpringBoot整合Shiro的方法详解

作者：指尖听戏

Apache Shiro是一个java安全（权限）框架，Shiro可以非常容易的开发出足够好的应用，其不仅可以用在javase环境，也可以用在javaee环境。本文介绍了SpringBoot整合Shiro的方法，需要的可以参考一下

1.Shito简介

1.1 什么是shiro

Apache Shiro是一个java安全（权限）框架

Shiro可以非常容易的开发出足够好的应用，其不仅可以用在javase环境，也可以用在javaee环境

shiro可以完成，认证，授权，加密，会话管理，web集成，缓存等。

1.2 有哪些功能

2.QuickStart

Git下载地址

官网下载的可能慢一些

首先新建一个普通的maven项目，然后在项目中导入新的maven项目模块，结构如下：

然后开始创建我们需要的文件，这些文件都可以在官网下载的文件中可以找到：

shiro.ini：

# Users and their assigned roles
#
# Each line conforms to the format defined in the
# org.apache.shiro.realm.text.TextConfigurationRealm#setUserDefinitions JavaDoc
# -----------------------------------------------------------------------------
[users]
# user 'root' with password 'secret' and the 'admin' role
root = secret, admin
# user 'guest' with the password 'guest' and the 'guest' role
guest = guest, guest
# user 'presidentskroob' with password '12345' ("That's the same combination on
# my luggage!!!" ;)), and role 'president'
presidentskroob = 12345, president
# user 'darkhelmet' with password 'ludicrousspeed' and roles 'darklord' and 'schwartz'
darkhelmet = ludicrousspeed, darklord, schwartz
# user 'lonestarr' with password 'vespa' and roles 'goodguy' and 'schwartz'
lonestarr = vespa, goodguy, schwartz

# -----------------------------------------------------------------------------
# Roles with assigned permissions
#
# Each line conforms to the format defined in the
# org.apache.shiro.realm.text.TextConfigurationRealm#setRoleDefinitions JavaDoc
# -----------------------------------------------------------------------------
[roles]
# 'admin' role has all permissions, indicated by the wildcard '*'
admin = *
# The 'schwartz' role can do anything (*) with any lightsaber:
schwartz = lightsaber:*
# The 'goodguy' role is allowed to 'drive' (action) the winnebago (type) with
# license plate 'eagle5' (instance specific id)
goodguy = winnebago:drive:eagle5

导入相关依赖 pom.xml,官网未给出详细的依赖，具体的参考给出的git下载的文件，然后做了一些简单的修改。

最重要的配置文件：

QuickStart:

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.mgt.DefaultSecurityManager;
import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.realm.text.IniRealm;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.Subject;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import javax.naming.InitialContext;


public class Quickstart {

    private static final transient Logger log = LoggerFactory.getLogger(Quickstart.class);


    public static void main(String[] args) {
        // 旧方法，由于shiro更新无法正常使用
        // Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
        // SecurityManager securityManager = factory.getInstance();


        // 新方法 shiro更新问题 解决正常运行
        DefaultSecurityManager securityManager = new DefaultSecurityManager();
        IniRealm iniRealm = new IniRealm("classpath:shiro.ini");
        securityManager.setRealm(iniRealm);

        SecurityUtils.setSecurityManager(securityManager);

        // Now that a simple Shiro environment is set up, let's see what you can do:

        // 获取当前用户对象
        Subject currentUser = SecurityUtils.getSubject();

        // 通过当前用户拿到session
        Session session = currentUser.getSession();
        session.setAttribute("someKey", "aValue");
        String value = (String) session.getAttribute("someKey");
        if (value.equals("aValue")) {
            log.info("subject =>! [" + value + "]");
        }

        // 判断当前用户是否被认证
        if (!currentUser.isAuthenticated()) {
            UsernamePasswordToken token = new UsernamePasswordToken("lonestarr", "vespa");
            token.setRememberMe(true);  // 设置记住我
            try {
                currentUser.login(token);
            } catch (UnknownAccountException uae) {
                log.info("There is no user with username of " + token.getPrincipal());
            } catch (IncorrectCredentialsException ice) {
                log.info("Password for account " + token.getPrincipal() + " was incorrect!");
            } catch (LockedAccountException lae) {
                log.info("The account for username " + token.getPrincipal() + " is locked.  " +
                        "Please contact your administrator to unlock it.");
            }
            // 最重要的一个异常，认证异常
            catch (AuthenticationException ae) {
                //unexpected condition?  error?
            }
        }

        //say who they are:
        //print their identifying principal (in this case, a username):
        log.info("User [" + currentUser.getPrincipal() + "] logged in successfully.");

        //test a role:
        if (currentUser.hasRole("schwartz")) {
            log.info("May the Schwartz be with you!");
        } else {
            log.info("Hello, mere mortal.");
        }

        // 测试一个简单的权限
        // 粗粒度的一个权限限制
        if (currentUser.isPermitted("lightsaber:wield")) {
            log.info("You may use a lightsaber ring.  Use it wisely.");
        } else {
            log.info("Sorry, lightsaber rings are for schwartz masters only.");
        }

        //a (very powerful) Instance Level permission:
        if (currentUser.isPermitted("winnebago:drive:eagle5")) {
            log.info("You are permitted to 'drive' the winnebago with license plate (id) 'eagle5'.  " +
                    "Here are the keys - have fun!");
        } else {
            log.info("Sorry, you aren't allowed to drive the 'eagle5' winnebago!");
        }

        //注销功能
        currentUser.logout();

        System.exit(0);
    }
}

以上主要的几个关键部分代码：

对象初始化部分

// 新方法 shiro更新问题 解决正常运行
DefaultSecurityManager securityManager = new DefaultSecurityManager();
IniRealm iniRealm = new IniRealm("classpath:shiro.ini");
securityManager.setRealm(iniRealm);

SecurityUtils.setSecurityManager(securityManager);

获取当前用户

Subject currentUser = SecurityUtils.getSubject();

判断用户是否被认证

!currentUser.isAuthenticated()

判断用户是否具有什么角色

currentUser.hasRole("schwartz")

判断用户是否拥有权限

currentUser.isPermitted("lightsaber:wield")

注销

currentUser.logout();

此时我们运行启动，项目如下，那么一个简单的shiro quickStart 就已经启动好了。

注意

shir最重要的三个部分：

3.SpringBoot中集成

1.导入shiro相关依赖

    <!--
    subject  用户
    SecurityManager 管理所有用户
    Realm 连接数据
    -->
    <!--shiro与springboot-->
    <dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring</artifactId>
    <version>1.6.0</version>
    </dependency>

2.自定义UserRealm

package com.nuist.shirospringboot.config;

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;

/**
 * @author liuhuanhuan
 * @version 1.0
 * @date 2022/5/8 17:59
 * @Description
 */
public class UserRealm extends AuthorizingRealm {
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("执行了=》授权doGetAuthorizationInfo方法");
        return null;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        System.out.println("执行了-》认证doGetAuthenticationInfo");
        return null;
    }
}

3.定义shiroConfig

package com.nuist.shirospringboot.config;

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

/**
 * @author liuhuanhuan
 * @version 1.0
 * @date 2022/5/8 17:58
 * @Description
 */
@Configuration
public class ShiroConfig {
    // shiroFilterConfiguere

    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("getDefaultWebSecurityManager") DefaultWebSecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        // 设置用户管理器
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        return shiroFilterFactoryBean;
    }
    // defaultWebSecurity
    // 通过@Qualifier 是USerRealm进行绑定
    @Bean
    public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userReaml") UserRealm userReaml) {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        // 关联Realm
        securityManager.setRealm(userReaml);
        return securityManager;
    }


    // 创建realm对象  需要去进行自定义，这样就可以交给spring去进行托管了
    @Bean
    public UserRealm userReaml(){
        return new UserRealm();
    }
}

4.新建页面进行测试

package com.nuist.shirospringboot.controller;

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

/**
 * @author liuhuanhuan
 * @version 1.0
 * @date 2022/5/8 17:52
 * @Description
 */
@Controller
public class Mycontrollrt
{
    @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";
    }
}

index.html

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

<h1>首页</h1>
<p th:text="${msg}"></p>
<hr>
<a th:href="@{/user/add}">add </a>  |  <a th:href="@{/user/update}">update</a>
</body>
</html>

user/add.html

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

user/update.html

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

<h1>update</h1>

</body>
</html>

此时一个简单的项目就搭建起来了，然后开始shiro的认证授权的操作。

我们只需要在配置中添加如下代码：

        Map<String,String> filterMap = new LinkedHashMap<>();
//        filterMap.put("/user/add","authc");
//        filterMap.put("/user/update","authc");
        filterMap.put("/user/*","authc");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterMap);

        shiroFilterFactoryBean.setLoginUrl("/toLogin");

此时就对我们所有的页面请求进行了拦截，然后转发到login的页面

login.html:

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

<h1>login</h1>
<hr>
<form action="">
    <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>

此时在页面进行点击的时候，我们就无法正常进入页面，只能进入到我们的登录页面

进行登录验证的拦截，只有输入正确的账号密码才能够进入：

MyCOntroller中新增如下代码：

    @RequestMapping("/login")
    public String login(String username,String password,Model model) {
        // 获取当前用户
        Subject subject = SecurityUtils.getSubject();
        // 封装当前用户
        UsernamePasswordToken usernamePasswordToken = new UsernamePasswordToken(username, password);
        try {
            subject.login(usernamePasswordToken); // 执行登录的方法，有异常进行处理
            return "index";
        } catch (UnknownAccountException e){
            model.addAttribute("msg","用户名错误");
            return "login";
        } catch (IncorrectCredentialsException e) { // 密码不存在
            model.addAttribute("msg","密码错误");
            return "login";
        }
    }

然后修改login页面的代码

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

<h1>login</h1>
<hr>
<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>

然后在我们的UserRealm

中doGetAuthenticationInfo方法中新增代码

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        System.out.println("执行了-》认证doGetAuthenticationInfo");
        String name = "root";
        String password = "123456";
        UsernamePasswordToken authenticationToken1 = (UsernamePasswordToken) authenticationToken;
        if (!authenticationToken1.getUsername().equals(name)) {
            return null;   // 抛出异常
        }
        // 密码认证  shiro去做
        return new SimpleAuthenticationInfo("",password,"");
    }

此时我们通过UsernamePasswordToken 获取我们封装好的账号和密码，但是我们只需要进行账号的认证，密码的认证交给我们的shiro去做就可以了。

具体的用户授权，我们可以进行连接数据库的设置，但是我为了偷懒，我就不去手动创建与数据库的链接啦。

下面我们来进行页面的授权操作

我们想要进行用户的授权操作

我们需要在shiroConfig中新增如下代码：

filterMap.put("/user/add","perms[user:add]");

此时代表如果用户拥有user:add操作的话，可以显示，如果没有的话就不能正常显示

我们可以自定义一个页面来用于返回信息的显示：

 @RequestMapping("/noauth")    
 @ResponseBody                 
 public String noauth() {      
     return "未经过授权无法进行访问";     
 }

当用户没有add权限的时候，我们就提示无法显示：

此时我们就完成了单个的用户授权的操作。此时我们再去进行具体的页面操作

shiro与thymeleaf的结合：

需要将我们进行验证的页面进行如下操作：

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

<h1>首页</h1>
<p>
    <a th:href="@{/toLogin}">登录</a>
</p>

<p th:text="${msg}"></p>
<hr>
<div shiro:hasPermission="user:add">
    <a th:href="@{/user/add}">add </a>
</div>
 |
<div shiro:hasPermission="user:update">
    <a th:href="@{/user/update}">update</a>
</div>
</body>
</html>

此时应用的方式和springsecurity的方式基本一致。

然后在我们的授权页面进行操作如下：

UserRealm中修改doGetAuthorizationInfo方法，如下：

    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("执行了=》授权doGetAuthorizationInfo方法");
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();

        // 新增授权页面
        authorizationInfo.addStringPermission("user:add");

        // 拿到当前对象 ,然后通过对象中的授权方式进行判断

        return authorizationInfo;
    }

此时我们赋予用户只有add的权限，那么按理说在页面中是无法显示update的按钮，那么我们进行测试下，是否可以正常使用：

此时认证授权部分已经成功啦，以上就是我们进行的一个小小的demo,更深入的学习，后续继续更新。
