SpringBoot-09 Shiro

Hello Shiro

可以先创建一个最单纯的Maven项目。

1.导入依赖

<dependencies>
    <dependency>
        <groupId>org.apache.shiro</groupId>
        <artifactId>shiro-core</artifactId>
        <version>1.7.0</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jcl-over-slf4j</artifactId>
        <version>2.0.0-alpha1</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
        <version>2.0.0-alpha1</version>
    </dependency>
    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.17</version>
    </dependency>
</dependencies>

这里我导入的依赖基本上都是最新版,如果想要别的版本可以自行搜索导入

2.创建log4j.properties

log4j.rootLogger=INFO, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m %n
# General Apache libraries
log4j.logger.org.apache=WARN
# Spring
log4j.logger.org.springframework=WARN
# Default Shiro logging
log4j.logger.org.apache.shiro=INFO
# Disable verbose logging
log4j.logger.org.apache.shiro.util.ThreadContext=WARN
log4j.logger.org.apache.shiro.cache.ehcache.EhCache=WARN

3.创建shiro.ini

这里第一次创建ini文件,会让你选择,可以选择txt文件,创建成功后会提示你创下载一个ini插件

[users]
root = secret, admin
guest = guest, guest
presidentskroob = 12345, president
darkhelmet = ludicrousspeed, darklord, schwartz
lonestarr = vespa, goodguy, schwartz
[roles]
admin = *
schwartz = lightsaber:*
goodguy = winnebago:drive:eagle5

4.创建Quickstart

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.config.IniSecurityManagerFactory;
import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.Subject;
import org.apache.shiro.util.Factory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Quickstart {
    private static final transient Logger log = LoggerFactory.getLogger(Quickstart.class);
    public static void main(String[] args) {
        // The easiest way to create a Shiro SecurityManager with configured
        // realms, users, roles and permissions is to use the simple INI config.
        // We'll do that by using a factory that can ingest a .ini file and
        // return a SecurityManager instance:

        // Use the shiro.ini file at the root of the classpath
        // (file: and url: prefixes load from files and urls respectively):
        Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
        SecurityManager securityManager = factory.getInstance();

        // for this simple example quickstart, make the SecurityManager
        // accessible as a JVM singleton.  Most applications wouldn't do this
        // and instead rely on their container configuration or web.xml for
        // webapps.  That is outside the scope of this simple quickstart, so
        // we'll just do the bare minimum so you can continue to get a feel
        // for things.
        SecurityUtils.setSecurityManager(securityManager);
        // Now that a simple Shiro environment is set up, let's see what you can do:
        // get the currently executing user:
        Subject currentUser = SecurityUtils.getSubject();
        // Do some stuff with a Session (no need for a web or EJB container!!!)
        Session session = currentUser.getSession();
        session.setAttribute("someKey", "aValue");
        String value = (String) session.getAttribute("someKey");
        if (value.equals("aValue")) {
            log.info("Retrieved the correct value! [" + value + "]");
        }
        // let's login the current user so we can check against roles and permissions:
        if (!currentUser.isAuthenticated()) {
            UsernamePasswordToken token = new UsernamePasswordToken("lonestarr", "vespa");
            token.setRememberMe(true);
            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.");
            }
            // ... catch more exceptions here (maybe custom ones specific to your application?
            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.");
        }
        //test a typed permission (not instance-level)
        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!");
        }
        //all done - log out!
        currentUser.logout();
        System.exit(0);
    }
}

5.启动测试

SpringBoot-09  Shiro _ JavaClub全栈架构师技术笔记

6.可能遇到错误

SpringBoot-09  Shiro _ JavaClub全栈架构师技术笔记

解决办法:

这是因为你的依赖中的问题:

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>jcl-over-slf4j</artifactId>
    <version>2.0.0-alpha1</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>2.0.0-alpha1</version>
    <scope>test</scope>
</dependency>

依赖中存在 test ,会出现错误,删掉就行了。

Shiro环境搭建

对于shiro环境,一共有三个要素:

  • ShiroFilterFactoryBean
  • DefaultWebSecurityManager
  • Realm

我们需要倒着来创建

创建一个config文件夹,和ShiroConfig、UserRealm类

public class UserRealm extends AuthorizingRealm {
    // 授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        return null;
    }
    //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException     {
        return null;
    }
}
@Configuration
public class ShiroConfig {
    //ShiroFilterFactoryBean
    @Bean
    public ShiroFilterFactoryBean shiroFilterFactoryBean(@Qualifier("defaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
        //设置安全管理器
        bean.setSecurityManager(defaultWebSecurityManager);
        return bean;
    }
    //DefaultWebSecurityManager
    @Bean
    public DefaultWebSecurityManager defaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
        DefaultWebSecurityManager SecurityManager = new DefaultWebSecurityManager();
        SecurityManager.setRealm(userRealm);
        return SecurityManager;
    }
    //创建 realm 对象
    @Bean
    public UserRealm userRealm(){
        return new UserRealm();
    }
}

以上就完成了shiro的基本框架搭建。

登录拦截

1.前置准备

用来测试的话,我们需要:

add.html、index.html、login.html和一个Controller类

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
add
</body>
</html>
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
首页<br>
<a th:href="@{/add}">add</a><br>
</body>
</html>
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<form action="">
    姓名:<input type="text" name="username"><br>
    密码:<input type="text" name="password"><br>
    <input type="submit" value="提交">
</form>
</body>
</html>
@Controller
public class ShiroController {
    @RequestMapping({"/","/index.html"})
    public String index(){
        return "index";
    }
    @RequestMapping("/add")
    public String add(){
        return "add";
    }
    @RequestMapping("/toLogin")
    public String login(){
        return "login";
    }
}

2.配置

上述文件页面搭建好后,测试运行应该是没什么问题的,我们开始在ShiroConfig类中配置

 @Bean
public ShiroFilterFactoryBean shiroFilterFactoryBean(@Qualifier("defaultWebSecurityManager") 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:无需认证就可以访问
        *  authc:必须认证了才能访问
        *  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访问
        *  role:拥有某个角色权限才能访问
        */
    Map<String, String> map = new LinkedHashMap<>();
    map.put("/add","authc");
    map.put("/update","authc");
    bean.setFilterChainDefinitionMap(map);
    //设置登录请求
    bean.setLoginUrl("/toLogin");
    return bean;
}

这时候,如果没有权限,点击add会自动进入设置的登陆页面。

3.用户权限添加

添加登录Controller

@RequestMapping("/Login")
public String login(String username, String password, Model model){
    //获取当前用户
    Subject subject = SecurityUtils.getSubject();
    //封装用户的登陆数据
    UsernamePasswordToken token = new UsernamePasswordToken(username,password);
    try {
        subject.login(token);
        return "index";
    } catch (UnknownAccountException uae) {
        model.addAttribute("msg","用户名错误");
        return "login";
    } catch (IncorrectCredentialsException ice) {
        model.addAttribute("msg","密码错误");
        return "login";
    }
}

修改UserRealm

//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
    //用户名密码   先用下面的测试,之后可以连接数据库
    String name="root";
    String password="123456";
    UsernamePasswordToken Token = (UsernamePasswordToken) authenticationToken;
    if (!Token.getUsername().equals(name)){
        return null;  //自动抛出异常
    }
    //密码认证  shiro来做
    return new SimpleAuthenticationInfo("",password,"");
}

修改登录页面

<p th:text="${msg}"></p>
<form th:action="@{/Login}">
    姓名:<input type="text" name="username"><br>
    密码:<input type="text" name="password"><br>
    <input type="submit" value="提交">
</form>

之后就可以去测试了。

整合Mybatis

1.导入依赖

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
</dependency>
<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.17</version>
</dependency>
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid</artifactId>
    <version>1.2.3</version>
</dependency>
<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.1.3</version>
</dependency>

2.配置文件

application.yml:

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    username: root
    password: 148729
    url: jdbc:mysql://localhost:3306/mybatistest?serverTime=UTC&useUnicode=true&characterEncoding=utf-8
    #druid配置
    #配置初始化大小/最小/最大
    initialSize: 5
    minIdle: 5
    maxActive: 20
    #获取连接等待超时时间
    maxWait: 60000
    #间隔多久进行一次检测,检测需要关闭的空闲连接
    timeBetweenEvictionRunsMillis: 60000
    #一个连接在池中最小生存的时间
    minEvictableIdleTimeMillis: 300000
    validationQuery: SELECT 1 FROM DUAL
    testWhileIdle: true
    testOnBorrow: false
    testOnReturn: false
    #打开PSCache,并指定每个连接上PSCache的大小。oracle设为true,mysql设为false。分库分表较多推荐设置为false
    poolPreparedStatements: false
    maxPoolPreparedStatementPerConnectionSize: 20
    #监控统计拦截的filters,stat:监控统计;log4j:日志记录;wall:防御sql注入;如果启用log4j记得添加依赖
    filters: stat,wall,log4j
    useGlobalDataSourceStat: true
    connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

application.properties:

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

3.实体类

public class User {
    private Integer id;
    private String name;
    private String pwd;
    // Get/Set方法
    // toString()方法
    // 有参/无参方法
}

4.创建mapper接口

创建一个mapper文件夹,UserMapper:

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

5.mapper.xml

这个文件的位置按照之前配置:

在resources/mapper下

mybatis.mapper-locations=classpath:mapper/*.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.zc.mapper.UserMapper">
    <select id="queryUserByName" resultType="User">
        select * from user where name=#{name};
    </select>
</mapper>

5.修改UserRealm

//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
    UsernamePasswordToken Token = (UsernamePasswordToken) authenticationToken;  //用户名密码
    User user = userMapper.queryUserByName(Token.getUsername());
    String name=user.getName();
    String password=user.getPwd();
    if (user==null){
        return null;
    }
    //密码认证  shiro来做
    return new SimpleAuthenticationInfo("",password,"");
}

就可以进行测试了。

授权、权限管理

创建一个未经授权无法访问Controlle方法:

@RequestMapping("/noauth")
@ResponseBody
public String unauthorized(){
    return "未经授权无法访问此页面";
}

修改ShiroConfig

@Bean
public ShiroFilterFactoryBean shiroFilterFactoryBean(@Qualifier("defaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){
    ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
    //设置安全管理器
    bean.setSecurityManager(defaultWebSecurityManager);
    Map<String, String> map = new LinkedHashMap<>();
    //拦截
    map.put("/add","authc");
    map.put("/update","authc");
    
    //授权
    map.put("/add","perms[user:add]");

    bean.setFilterChainDefinitionMap(map);
    //设置登录请求
    bean.setLoginUrl("/toLogin");
    //拦截页面
    bean.setUnauthorizedUrl("/noauth");
    return bean;
}

测试

这个时候我已经给/add方法添加了user:add权限,只有有这个权限的用户才可以登录

这时候测试的话,会发现,即时登录成功通过了拦截,add页面也会显示未经授权无法访问此页面

UserRealm中授权

// 授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
    SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
    info.addStringPermission("user:add");
    return info;
}

现在,只要登陆的用户,都会被添加user:add权限

也可以进行数据库连接:

// 授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
    SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
    // 数据库中加入一个权限字段,可以这样查找
    Subject subject = SecurityUtils.getSubject();
    //认证部分传入,可以获取
    User principal = (User) subject.getPrincipal();
    info.addStringPermission(user.getxxx());
    return info;
}

//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
    UsernamePasswordToken Token = (UsernamePasswordToken) authenticationToken;  //用户名密码
    User user = userMapper.queryUserByName(Token.getUsername());
    String password=user.getPwd();
    if (user==null){
        return null;
    }
    //这里修改了,传入了user,在授权部分可以获取
    return new SimpleAuthenticationInfo(user,password,"");
}

整合Thymeleaf

1.导入依赖

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

2.修改index.html

导入头文件

<html lang="en" xmlns:th="http://www.thymeleaf.org"  xmlns:shiro="http://www.thymeleaf.org/thymeleaf-extras-shiro" >

内部文件

<body>
    首页<br>
    <a th:href="@{/toLogin}">登录</a><br>
    <div shiro:hasPermission="user:add">
        <a th:href="@{/add}">add</a><br>
    </div>
    <a th:href="@{/update}">update</a>
</body>

这种,是最简单的页面整理,不同权限会显示不同页面,没有权限部分功能不展示。
