从外部来看Shiro,即从应用程序角度的来观察如何使用Shiro完成工作
我们参照git上的官方项目,创建自己的项目

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):
// 读取配置文件:
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:
// 获取当前的用户对象 Subject
Subject currentUser = SecurityUtils.getSubject();
// Do some stuff with a Session (no need for a web or EJB container!!!)
//通过当前用户拿到Shiro的Session 可以脱离web存值取值
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:
//判断当前的用户是否被认证
if (!currentUser.isAuthenticated()) {
//Token 令牌
UsernamePasswordToken token = new UsernamePasswordToken("lonestarr", "vespa");
//设置记住我
token.setRememberMe(true);
try {
//执行登录操作
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:
// 检查角色
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)
//粗粒度
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:
//细粒度
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!
//注销
currentUser.logout();
//结束
System.exit(0);
}
}
启动测试
从注释中,我们可以看出,前几行代码其实可以通过配置来完成,官方也推荐这么做,因此,去掉注释,精简代码
核心代码为
// 获取当前的用户对象 Subject
Subject currentUser = SecurityUtils.getSubject();
Session session = currentUser.getSession();
currentUser.isAuthenticated()
currentUser.getPrincipal()
currentUser.hasRole("schwartz")
currentUser.isPermitted("lightsaber:wield")
currentUser.logout();
与 spring security 非常详相近
新建springboot 模块
添加controller
@Controller
public class MyController {
@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";
}
}
首页 index.html页面
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">

<h1>首页</h1>

<hr>
<a th:href="@{/user/add}">add</a> | <a th:href="@{/user/update}">update</a>
</div>
</body>

新建一个add.html页面
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>add</h1>
</body>

项目结构
运行测试
添加 shiro 整合 spring 的依赖
<!--
Subject 用户
SecurityManager 管理所有用户
Realm 连接数据库

<!--shiro整合spring的包-->
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>

编写 ShiroConfig 配置类
@Configuration
public class ShiroConfig {
//3. shiroFilterFactoryBean
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("getDefaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager) {
ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
// 设置安全管理器
bean.setSecurityManager(defaultWebSecurityManager);
return bean;
}
//2. DefaultWebSecurityManager
@Bean
public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm) {
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
// 关联userRealm
securityManager.setRealm(userRealm);
return securityManager;
}
//1. 创建realm对象,需要自定义类
@Bean
public UserRealm userRealm() {
return new UserRealm();
}
}
这里有个细节注意:UserRealm 被注册bean,默认名字是 userRealm,因此在上面的方法参数中我们用注解@Qualifier(“userRealm”)来进行诸如,其实和使用 @Autowired 是一样的
编写一个自定义类 UserRealm
//自定义的UserRealm
public class UserRealm extends AuthorizingRealm {
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行了=>授权doGetAuthorizationInfo");
return null;
}
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
System.out.println("执行了=>认证doGetAuthorizationInfo");
return null;
}
}
在ShiroConfig中的getShiroFilterFactoryBean方法中添加如下配置
Map<String, String> filterMap = new LinkedHashMap<>();
filterMap.put("/user/add","authc");
filterMap.put("/user/update","authc");
bean.setFilterChainDefinitionMap(filterMap);
点击首页的add或者update之后
添加拦截成功页面,登录页面login.html
shiro没有security那样的默认登录页,需要我们自定义
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>登录页面</title>
</head>
<body>
<h1>登录</h1>
<hr>
<form action="">
<p>用户名:<input type="text" name="username"></p>
<p>密码:<input type="text" name="password"></p>
<p>密码:<input type="submit"></p>
</form>
</body>
</html>
在MyConfig中添加
@RequestMapping("/toLogin")
public String toLogin() {
return "login";
}
在ShiroConfig
中的getShiroFilterFactoryBean
方法中添加如下配置
//设置登录的请求
bean.setLoginUrl("/toLogin");
测试页面是否可以拦截成功
ShiroConfig
主要用于登录拦截配置。
UserRealm
主要用于用户的认证,授权操作,这两个类相互联动,实现功能
@RequestMapping("/login")
public String login(String username, String password, Model model) {
//获取一个用户
Subject subject = SecurityUtils.getSubject();
// 封装用户的登录数据
UsernamePasswordToken token = new UsernamePasswordToken(username, password);
try {
subject.login(token);//执行登录的方法,如果没有异常就说明ok了
return "index";
} catch (UnknownAccountException e) {
//用户名不存在
model.addAttribute("msg","用户名错误");
return "login"
