## 一、Shiro认证流程 ##

## 二、SpringBoot应用整合Shiro ##

*  JavaSE应用中使用
 *  web应用中使用
    
     *  SSM整合Shiro(配置多，用的少)
     *  SpringBoot应用整合Shiro

2.1 创建SpringBoot应用

*  lombok
 *  spring web
 *  thymeleaf

2.2 整合Druid和MyBatis

*  依赖
    
        
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.1.10</version>
        </dependency>
         
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.47</version>
        </dependency>
        
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.1.0</version>
        </dependency>
 *  配置
    
        spring:
          datasource:
            druid:
              url: jdbc:mysql://47.96.11.185:3306/test
              # MySQL如果是8.x   com.mysql.cj.jdbc.Driver
              driver-class-name: com.mysql.jdbc.Driver
              username: root
              password: admin123
              initial-size: 1
              min-idle: 1
              max-active: 20
        mybatis:
          mapper-locations: classpath:mappers/*Mapper.xml
          type-aliases-package: com.qfedu.springbootssm.beans

2.3 整合Shiro

*  导入依赖
    
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>1.4.1</version>
        </dependency>
 *  Shiro配置（java配置方式）
    
     *  SpringBoot默认没有提供对Shiro的自动配置
    
        @Configuration
        public class ShiroConfig {
        
            @Bean
            public IniRealm getIniRealm(){
                IniRealm iniRealm = new IniRealm("classpath:shiro.ini");
                return iniRealm;
            }
        
            @Bean
            public DefaultWebSecurityManager getDefaultWebSecurityManager(IniRealm iniRealm){
                DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
                //securityManager要完成校验，需要realm
                securityManager.setRealm(iniRealm);
                return securityManager;
            }
        
            @Bean
            public ShiroFilterFactoryBean shiroFilter(DefaultWebSecurityManager securityManager){
                ShiroFilterFactoryBean filter = new ShiroFilterFactoryBean();
                //过滤器就是shiro就行权限校验的核心，进行认证和授权是需要SecurityManager的
                filter.setSecurityManager(securityManager);
        
                //设置shiro的拦截规则
                // anon   匿名用户可访问
                // authc  认证用户可访问
                // user   使用RemeberMe的用户可访问
                // perms  对应权限可访问
                // role   对应的角色可访问
                Map<String,String> filterMap = new HashMap<>();
                filterMap.put("/","anon");
                filterMap.put("/login.html","anon");
                filterMap.put("/regist.html","anon");
                filterMap.put("/user/login","anon");
                filterMap.put("/user/regist","anon");
                filterMap.put("/static/**","anon");
                filterMap.put("/**","authc");
        
                filter.setFilterChainDefinitionMap(filterMap);
                filter.setLoginUrl("/login.html");
                //设置未授权访问的页面路径
                filter.setUnauthorizedUrl("/login.html");
                return filter;
            }
        
        
        }
 *  认证测试
    
     *  UserServiceImpl.java
    
        @Service
        public class UserServiceImpl {
        
            public void checkLogin(String userName,String userPwd) throws Exception{
                Subject subject = SecurityUtils.getSubject();
                UsernamePasswordToken token = new UsernamePasswordToken(userName,userPwd);
                subject.login(token);
            }
        
        }
    
     *  UserController.java
    
        @Controller
        @RequestMapping("user")
        public class UserController {
        
            @Resource
            private UserServiceImpl userService;
        
            @RequestMapping("login")
            public String login(String userName,String userPwd){
                try {
                    userService.checkLogin(userName,userPwd);
                    System.out.println("------登录成功！");
                    return "index";
                } catch (Exception e) {
                    System.out.println("------登录失败！");
                    return "login";
                }
        
            }
        }
 *  login.html

<!DOCTYPE html>
      <html lang="en">
      <head>
          <meta charset="UTF-8">
          <title>Title</title>
      </head>
      <body>
          login
          <hr/>
          <form action="user/login">
              <p>帐号:<input type="text" name="userName"/></p>
              <p>密码:<input type="text" name="userPwd"/></p>
              <p><input type="submit" value="登录"/></p>
          </form>
      </body>
      </html>

## 三、SpringBoot应用整合Shiro—案例（JdbcRealm） ##

3.1 JdbcRealm介绍

*  如果使用JdbcRealm，则必须提供JdbcRealm所需的表结构(权限设计)

3.2 JdbcRealm规定的表结构

*  用户信息表： users
    
        create table users(
            id int primary key auto_increment,
            username varchar(60) not null unique,
            password varchar(20) not null,
            password_salt varchar(20)
        );
        
        insert into users(username,password) values('zhangsan','123456');
        insert into users(username,password) values('lisi','123456');
        insert into users(username,password) values('wangwu','123456');
        insert into users(username,password) values('zhaoliu','123456');
        insert into users(username,password) values('chenqi','123456');
 *  角色信息表： user\_roles
    
        create table user_roles(
            id int primary key auto_increment,
            username varchar(60) not null,
            role_name varchar(100) not null
        );
        
        -- admin系统管理员
        -- cmanager 库管人员
        -- xmanager 销售人员
        -- kmanager 客服人员
        -- zmanager 行政人员 
        insert into user_roles(username,role_name) values('zhangsan','admin');
        insert into user_roles(username,role_name) values('lisi','cmanager');
        insert into user_roles(username,role_name) values('wangwu','xmanager');
        insert into user_roles(username,role_name) values('zhaoliu','kmanager');
        insert into user_roles(username,role_name) values('chenqi','zmanager');
        
 *  权限信息表：roles\_permissions
    
        create table roles_permissions(
            id int primary key auto_increment,
            role_name varchar(100) not null,
            permission varchar(100) not null
        );
        
        -- 权限  sys:c:save   sys:c:delete...
        -- 管理员具备所有权限
        insert into roles_permissions(role_name,permission) values("admin","*");
        -- 库管人员
        insert into roles_permissions(role_name,permission) values("cmanager","sys:c:save");        
        insert into roles_permissions(role_name,permission) values("cmanager","sys:c:delete");
        insert into roles_permissions(role_name,permission) values("cmanager","sys:c:update");
        insert into roles_permissions(role_name,permission) values("cmanager","sys:c:find");
        -- 销售人员
        insert into roles_permissions(role_name,permission) values("xmanager","sys:c:find");
        insert into roles_permissions(role_name,permission) values("xmanager","sys:x:save");
        insert into roles_permissions(role_name,permission) values("xmanager","sys:x:delete");
        insert into roles_permissions(role_name,permission) values("xmanager","sys:x:update");
        insert into roles_permissions(role_name,permission) values("xmanager","sys:x:find");
        
        insert into roles_permissions(role_name,permission) values("xmanager","sys:k:save");
        insert into roles_permissions(role_name,permission) values("xmanager","sys:k:delete");
        insert into roles_permissions(role_name,permission) values("xmanager","sys:k:update");
        insert into roles_permissions(role_name,permission) values("xmanager","sys:k:find");
        -- 客服人员
        insert into roles_permissions(role_name,permission) values("kmanager","sys:k:find");
        insert into roles_permissions(role_name,permission) values("kmanager","sys:k:update");
        -- 新增人员
        insert into roles_permissions(role_name,permission) values("zmanager","sys:*:find");

3.3 SpringBoot整合Shiro

*  创建SpringBoot应用
 *  整合Druid和MyBatis
 *  整合shiro
    
     *  添加依赖
        
            <dependency>
                <groupId>org.apache.shiro</groupId>
                <artifactId>shiro-spring</artifactId>
                <version>1.4.1</version>
            </dependency>

*  配置Shiro
    
        @Configuration
        public class ShiroConfig {
        
            @Bean
            public JdbcRealm getJdbcRealm(DataSource dataSource){
                JdbcRealm jdbcRealm = new JdbcRealm();
                //JdbcRealm会自行从数据库查询用户及权限数据（数据库的表结构要符合JdbcRealm的规范）
                jdbcRealm.setDataSource(dataSource);
                //JdbcRealm默认开启认证功能，需要手动开启授权功能
                jdbcRealm.setPermissionsLookupEnabled(true);
                return  jdbcRealm;
            }
        
            @Bean
            public DefaultWebSecurityManager getDefaultWebSecurityManager(JdbcRealm jdbcRealm){
                DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
                securityManager.setRealm(jdbcRealm);
                return securityManager;
            }
        
            @Bean
            public ShiroFilterFactoryBean shiroFilter(DefaultWebSecurityManager securityManager){
                ShiroFilterFactoryBean filter = new ShiroFilterFactoryBean();
                //过滤器就是shiro就行权限校验的核心，进行认证和授权是需要SecurityManager的
                filter.setSecurityManager(securityManager);
        
                Map<String,String> filterMap = new HashMap<>();
                filterMap.put("/","anon");
                filterMap.put("/login.html","anon");
                filterMap.put("/regist.html","anon");
                filterMap.put("/user/login","anon");
                filterMap.put("/user/regist","anon");
                filterMap.put("/static/**","anon");
                filterMap.put("/**","authc");
        
                filter.setFilterChainDefinitionMap(filterMap);
                filter.setLoginUrl("/login.html");
                //设置未授权访问的页面路径
                filter.setUnauthorizedUrl("/login.html");
                return filter;
            }
        
        }

3.4 认证功能测试

略

## 四、Shiro的标签使用 ##

> 当用户认证进入到主页面之后，需要显示用户信息及当前用户的权限信息；Shiro就提供了一套标签用于在页面来进行权限数据的呈现

*  Shiro提供了可供JSP使用的标签以及Thymeleaf中标签
    
     *  JSP页面中引用：
        
            <%@ taglib prefix="shiro" uri="http://shiro.apache.org/tags" %>
     *  Thymeleaf模版中引用(重点)：
        
         *  在pom.xml文件中导入thymeleaf模版对shiro标签支持的依赖
        
            <dependency>
                <groupId>com.github.theborakompanioni</groupId>
                <artifactId>thymeleaf-extras-shiro</artifactId>
                <version>2.0.0</version>
            </dependency>
        
         *  在ShiroConfig中配置Shiro的
        
            @Configuration
            public class ShiroConfig {
            
                @Bean
                public ShiroDialect getShiroDialect(){
                    return new ShiroDialect();
                }
                //...
            }
        
         *  Thymeleaf模版中引入shiro的命名空间
        
            <html xmlns:th="http://www.thymeleaf.org"
                  xmlns:shiro="http://www.pollix.at/thymeleaf/shiro">
                ...
            </html>

常用标签

*  guest，判断用户是否是游客身份，如果是游客身份则显示此标签内容
    
        <shiro:guest>
            欢迎游客访问，<a href="login.html">登录</a>
        </shiro:guest>
 *  user，判断用户是否是认证身份，如果是认证身份则显示此标签内容
 *  principal，获取当前登录用户名
    
        <shiro:user>
            用户[<shiro:principal/>]欢迎您！
        </shiro:user>
 *  notAuthenticated/authenticated
 *  hasRole
 *  hasPermission
