shiro简介
什么是Shiro?
Apache Shiro 是一个Java 的安全（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。
- ●Authentication:身份认证、登录，验证用户是不是拥有相应的身份;
- ●Authorization:授权，即权限验证，验证某个已认证的用户是否拥有某个权限，即判断用户能否进行什么操
- 作，如:验证某个用户是否拥有某个角色，或者细粒度的验证某个用户对某个资源是否具有某个权限!
- ●Session Manager:会话管理,即用户登录后就是第一次会话, 在没有退出之前，它的所有信息都在会话中;
- 会话可以是普通的JavaSE环境，也可以是Web环境;
- ●Cryptography:加密，保护数据的安全性，如密码加密存储到数据库中，而不是明文存储;
- ●Web Support: Web支持， 可以非常容易的集成到Web环境;
- ●Caching: 缓存，比如用户登录后,其用户信息，拥有的角色、权限不必每次去查,这样可以提高效率
- ●Concurrency: Shiro支持多线程应用的并发验证，即，如在一 个线程中开启另一 一个线程，能把权限自动的传
- 播过去
- ●Testing: 提供测试支持;
- ●Run As:允许-一个用户假装为另-一个用户(如果他们允许)的身份进行访问;
- ●Remember Me:记住我，这个是非常常见的功能，即一次登录后，下次再来的话不用登录了
- ●Subject: 任何可以与应用交互的'用户';
- ●Security Manager:相当于SpringMVC中的DispatcherServlet; 是Shiro的心脏，所有具体的交互都通过
- Security Manager进行控制，它管理者所有的Subject, 且负责进行认证，授权,会话，及缓存的管理。
- ●Authenticator: 负责Subject认证，是一个扩展点，可以自定义实现;可以使用认证策略(Authentication
- Strategy)，即什么情况下算用户认证通过了;
- ●Authorizer: 授权器，即访问控制器，用来决定主体是否有权限进行相应的操作;即控制着用户能访问应用中
- 的那些功能;
- ●Realm:可以有一个或者多个的realm, 可以认为是安全实体数据源，即用于获取安全实体的，可以用DBC实
- 现，也可以是内存实现等等,由用户提供;所以一般在应用中都需要实现自己的realm
- ●SessionManager: 管理Session生命周期的组件，而Shiro并不仅仅可以用在Web环境，也可以用在普通的
- JavaSE环境中
- ●Authorizer: 授权器，即访问控制器，用来决定主体是否有权限进行相应的操作;即控制着用户能访问应用中
- 的那些功能; .
- ●Realm: 可以有一一个或者多个的realm,可以认为是安全实体数据源，即用于获取安全实体的，可以用DBC实
- 现，也可以是内存实现等等，由用户提供;所以-般在应用中都需要实现自己的realm
- ●SessionManager: 管理Session生命周期的组件，而Shiro并不仅仅可以用在Web环境，也可以用在普通的
- JavaSE环境中
- CH用英J",简筵:
- ●CacheManager: 缓存控制器，来管理如用户，角色，权限等缓存的;因为这些数据基本上很少改变,放到缓
- 存中后可以提高访问的性能;
- ●Cryptography: 密码模块，Shiro提高了- -些常见的加密组件用于密码加密，解密等

在那个inl 里解释了角色的指定
Springboot 跟Shiro 环境搭建
1，导入依赖
<!--引入thymeleaf依赖-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<!-- shiro-spring 依赖-->

<artifactId>shiro-spring</artifactId>
<version>1.4.1</version>
</dependency>
复制代码写config 类
Shior Config 类
package com.jj.demo.config;
import org.apache.shiro.mgt.SecurityManager;
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 {
// shiro 的三个
// Subject 用户
@Bean
public ShiroFilterFactoryBean shiroFilterFactoryBean(@Qualifier("defaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
shiroFilterFactoryBean.setSecurityManager(defaultWebSecurityManager);
return shiroFilterFactoryBean;
}
// SecurityManager 管理所有的用户
@Bean
public DefaultWebSecurityManager defaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
DefaultWebSecurityManager defaultWebSecurityManager = new DefaultWebSecurityManager();
// 关联 Realm
defaultWebSecurityManager.setRealm(userRealm);
return defaultWebSecurityManager;
}
// Realm 连接数据
@Bean
public UserRealm userRealm(){
return new UserRealm();
}
}
复制代码Shiro 主要的三个
// Subject 用户
// SecurityManager 管理所有的用户
// Realm 连接数据
复制代码写自己的Realm 类
package com.jj.demo.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;
public class UserRealm extends AuthorizingRealm {
// 授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("principalCollection = 授权" + principalCollection);
return null;
}
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
System.out.println("authenticationToken = 认证" + authenticationToken);
return null;
}
}
复制代码简单的几个页面和控制层
控制层
package com.jj.demo.control;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class Shirocontrol {
@RequestMapping({"/","/index"})
public String demo(Model model){
model.addAttribute("msg","你好啊，我的第一个Springboot-sgiro 程序！！");
return "index";
}
//跳转到添加
@RequestMapping("/user/add")
public String add(){
return "/user/add";
}
//跳转到更新
@RequestMapping("/user/update")
public String update(){
return "/user/update";
}
}
复制代码
实现登录拦截功能！！
简单的写个登录的控制层，还有登录页面就可以了
效果
走到了我们指定的url
控制层写一个登录的方法
// 登录的
@RequestMapping("login")
public String login1(String name,String pwd,Model model){
// 获取当前的用户
Subject subject = SecurityUtils.getSubject();
// 封装当前登录的数据 获取到令牌
UsernamePasswordToken token = new UsernamePasswordToken(name,pwd);
try {
subject.login(token); //执行登录的方法，没有异常就跳出
return "index";
//
// 用户名不存在异常
} catch (UnknownAccountException uae) {
model.addAttribute("msg","用户名错！！");
return "login";
}
catch (IncorrectCredentialsException ice) {
model.addAttribute("msg","密码错误");
return "login";
}
}
复制代码会自动与我们写的UserRealm 的认证联系起来。效果
2020-12-24 16:09:05.446 INFO 4028 --- [ main] com.jj.demo.DemoApplication : Started DemoApplication in 1.929 seconds (JVM running for 3.107)

authenticationToken = 认证org.apache.shiro.authc.UsernamePasswordToken - 娇娇, rememberMe=false
复制代码连接数据库测试
实体类简单的几个name,pwd
简单的根据name 做个查询 具体代码非常简单。在UserRealm 上注入service 层即可！！
在自己写的UserRealm 类里认证里写上

SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
// 添加方法
info.addStringPermission("vip:add");
info.addStringPermission("vip:update");
// 拿到当前登录的对象
Subject subject = SecurityUtils.getSubject();
// 拿到vip 对象
vip vip = (com.jj.demo.pojo.vip) subject.getPrincipal();
// 设置当前用户的权限
System.out.println("vip.getPerms() = " + vip.getPerms());
info.addStringPermission(vip.getPerms());
return info;
}
