功能 | 说明 |
---|---|
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某些操作,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 | 记住登录功能,即一次登录后,下次再来的话不用登录 |
subject:
SecurityManager
Realm
组件名称 | 说明 |
---|---|
Subject | 任何可以与应用交互的 ‘用户’; |
Security Manager | 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) |
Authorizer | 授权器【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JDBC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 |
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 提供了一些常见的加密组件用于密码加密,解密 |

编写Shiro 配置类 【config包下】
import org.springframework.context.annotation.Configuration;
//声明为配置类
@Configuration
public class ShiroConfig {
//创建 ShiroFilterFactoryBean
//创建 DefaultWebSecurityManager
//创建 realm 对象
}
先创建一个 realm 对象
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;
//自定义Realm
public class UserRealm extends AuthorizingRealm {
//执行授权逻辑
@Override
protected AuthorizationInfo
doGetAuthorizationInfo(PrincipalCollection principals) {
System.out.println("执行了=>授权逻辑PrincipalCollection");
return null;
}
//执行认证逻辑
@Override
protected AuthenticationInfo
doGetAuthenticationInfo(AuthenticationToken token) throws
AuthenticationException {
System.out.println("执行了=>认证逻辑AuthenticationToken");
return null;
}
}
将这个类注册到Bean中【ShiroConfig中】
@Configuration
public class ShiroConfig {
//创建 ShiroFilterFactoryBean
//创建 DefaultWebSecurityManager
//创建 realm 对象
@Bean
public UserRealm userRealm(){
return new UserRealm();
}
}
创建 DefaultWebSecurityManager
//创建 ShiroFilterFactoryBean
@Bean
public ShiroFilterFactoryBean
getShiroFilterFactoryBean(@Qualifier("securityManager")DefaultWebSecurityManager securityManager){
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
//设置安全管理器
shiroFilterFactoryBean.setSecurityManager(securityManager);
return shiroFilterFactoryBean;
}
ShiroConfig
全部代码
//声明为配置类
@Configuration
public class ShiroConfig {
//创建 ShiroFilterFactoryBean
@Bean
public ShiroFilterFactoryBean
getShiroFilterFactoryBean(@Qualifier("securityManager")DefaultWebSecurityManager securityManager){
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
//设置安全管理器
shiroFilterFactoryBean.setSecurityManager(securityManager);
return shiroFilterFactoryBean;
}
//创建 DefaultWebSecurityManager
@Bean(name = "securityManager")
public DefaultWebSecurityManager
getDefaultWebSecurityManager(@Qualifier("userRealm")UserRealm userRealm){
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
//关联Realm
securityManager.setRealm(userRealm);
return securityManager;
}
//创建 realm 对象
@Bean
public UserRealm userRealm(){
return new UserRealm();
}
}
编写两个页面、在templates目录下新建一个 user 目录 add.html update.html
<body>
<h1>addh1>
body>
<body>
<h1>updateh1>
body>
编写跳转到页面的controller
@RequestMapping("/user/add")
public String toAdd(){
return "user/add";
}
@RequestMapping("/user/update")
public String toUpdate(){
return "user/update";
}
在index页面上,增加跳转链接
<a th:href="@{/user/add}">adda>
<hr/>
<a th:href="@{/user/update}">updatea>
添加Shiro的内置过滤器
@Bean
public ShiroFilterFactoryBean
getShiroFilterFactoryBean(@Qualifier("securityManager")DefaultWebSecurityManager securityManager){
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
//设置安全管理器
shiroFilterFactoryBean.setSecurityManager(securityManager);
/*
添加Shiro内置过滤器,常用的有如下过滤器:
anon: 无需认证就可以访问
authc: 必须认证才可以访问
user: 如果使用了记住我功能就可以直接访问
perms: 拥有某个资源权限才可以访问
role: 拥有某个角色权限才可以访问
*/
Map<String,String> filterMap = new LinkedHashMap<String, String>();
filterMap.put("/user/add","authc");
filterMap.put("/user/update","authc");
shiroFilterFactoryBean.setFilterChainDefinitionMap(filterMap);
return shiroFilterFactoryBean;
}
编写自定义Login页面
DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>logintitle>
head>
<body>
<p th:text="${msg}" style="color: red">p>

<p>密码:<input type="text" name="password">p>
<p>
<button type="submit">登录button>
p>
form>
body>
html>
编写跳转的controller
@RequestMapping("/toLogin")
public String toLogin(){
return "login";
}
在shiro中配置
//shiroFilterFactoryBean
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") 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:无需认证既可以访问
author: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
//filterMap.put("/user/add","authc");
// filterMap.put("/user/update","authc");
*/
filterMap.put("/user/*","authc");
bean.setFilterChainDefinitionMap(filterMap);
//设置登录的页面
bean.setLoginUrl("/toLogin");
return bean;
}
编写一个登录的controller
//登录操作
@RequestMapping("/login")
public String login(String username,String password,Model model){
//使用shiro,编写认证操作
//1. 获取Subject
Subject subject = SecurityUtils.getSubject();
//2. 封装用户的数据
UsernamePasswordToken token = new UsernamePasswordToken(username,password);
//3. 执行登录的方法,只要没有异常就代表登录成功!
try {
subject.login(token); //登录成功!返回首页
return "index";
} catch (UnknownAccountException e) { //用户名不存在
model.addAttribute("msg","用户名不存在");
return "login";
} catch (IncorrectCredentialsException e) { //密码错误
model.addAttribute("msg","密码错误");
return "login";
}
}
在前端修改对应的信息输出或者请求
<p style="color:red;" th:text="${msg}">p>
<form th:action="@{/login}">
<p>用户名: <input type="text" name="username">p>
<p>密码: <input type="text" name="password">p>
<p> <input type="submit"> p>
form>
在 UserRealm 中编写用户认证的判断逻辑
//执行认证逻辑
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationTokentoken) throws AuthenticationException {
System.out.println("执行了=>认证逻辑AuthenticationToken");
//假设数据库的用户名和密码
String name = "root";
String password = "123456";
//1.判断用户名
UsernamePasswordToken userToken = (UsernamePasswordToken)token;
if (!userToken.getUsername().equals(name)){
//用户名不存在
return null; //shiro底层就会抛出 UnknownAccountException
}
//2. 验证密码,我们可以使用一个AuthenticationInfo实现类
SimpleAuthenticationInfo
// shiro会自动帮我们验证!重点是第二个参数就是要验证的密码!
return new SimpleAuthenticationInfo("", password, "");
