Shiro簡(jiǎn)介 Apache Shiro是一個(gè)強(qiáng)大且易用的Java安全框架,執(zhí)行身份驗(yàn)證、授權(quán)、密碼和會(huì)話管理 三個(gè)核心組件：Subject, SecurityManager 和 Realms Subject代表了當(dāng)前用戶的安全操作 SecurityManager管理所有用戶的安全操作，是Shiro框架的核心，Shiro通過(guò)SecurityManager來(lái)管理內(nèi)部組件實(shí)例，并通過(guò)它來(lái)提供安全管理的各種服務(wù)。 Realm充當(dāng)了Shiro與應(yīng)用安全數(shù)據(jù)間的“橋梁”或者“連接器”。也就是說(shuō)，當(dāng)對(duì)用戶執(zhí)行認(rèn)證（登錄）和授權(quán)（訪問(wèn)控制）驗(yàn)證時(shí)，Shiro會(huì)從應(yīng)用配置的Realm中查找用戶及其權(quán)限信息。 Realm實(shí)質(zhì)上是一個(gè)安全相關(guān)的DAO：它封裝了數(shù)據(jù)源的連接細(xì)節(jié)，并在需要時(shí)將相關(guān)數(shù)據(jù)提供給Shiro。當(dāng)配置Shiro時(shí)，你必須至少指定一個(gè)Realm，用于認(rèn)證和（或）授權(quán)。配置多個(gè)Realm是可以的，但是至少需要一個(gè)。 Shiro快速入門(mén)

編寫(xiě)shiro的配置類ShiroConfig.java

package com.example.config;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;import java.util.LinkedHashMap;import java.util.Map;@Configurationpublic class ShiroConfig { //3.

編寫(xiě)UserRealm.java

package com.example.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 { @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {System.out.println('授權(quán)');return null; } @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {System.out.println('認(rèn)證');return null; }}

編寫(xiě)controller測(cè)試環(huán)境是否搭建好

package com.example.controller;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class MyController { @RequestMapping({'/','/index'}) public String index(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'; }}

實(shí)現(xiàn)登錄攔截

在ShiroConfig.java文件中添加攔截

Map<String,String> filterMap = new LinkedHashMap<>();//對(duì)/user/*下的文件只有擁有authc權(quán)限的才能訪問(wèn)filterMap.put('/user/*','authc');//將Map存放到ShiroFilterFactoryBean中factoryBean.setFilterChainDefinitionMap(filterMap);

這樣，代碼跑起來(lái)，你點(diǎn)擊add或者update就會(huì)出現(xiàn)404錯(cuò)誤，這時(shí)候，我們?cè)倮^續(xù)添加，讓它跳轉(zhuǎn)到我們自定義的登錄頁(yè)

添加登錄攔截到登錄頁(yè)

//需進(jìn)行權(quán)限認(rèn)證時(shí)跳轉(zhuǎn)到toLoginfactoryBean.setLoginUrl('/toLogin');//權(quán)限認(rèn)證失敗時(shí)跳轉(zhuǎn)到unauthorizedfactoryBean.setUnauthorizedUrl('/unauthorized');

login.html

<!DOCTYPE html><html lang='en'><head> <meta charset='UTF-8'> <title>登錄</title></head><body><form action=''> 用戶名:<input type='text' name='username'><br> 密碼:<input type='text' name='password'><br> <input type='submit'></form></body></html>

視圖跳轉(zhuǎn)添加一個(gè)login頁(yè)面跳轉(zhuǎn)

@RequestMapping('/toLogin') public String login(){return 'login'; }

上面，我們已經(jīng)成功攔截了，現(xiàn)在我們來(lái)實(shí)現(xiàn)用戶認(rèn)證

首先，我們需要一個(gè)登錄頁(yè)面

login.html

<!DOCTYPE html><html lang='en' xmlns:th='http://www.w3.org/1999/xhtml'><head> <meta charset='UTF-8'> <title>登錄</title></head><body><p th:text='${msg}' style='color: red'></p><form th:action='@{/login}'> 用戶名:<input type='text' name='username'><br> 密碼:<input type='text' name='password'><br> <input type='submit'></form></body></html>

其次，去controller編寫(xiě)跳轉(zhuǎn)到登錄頁(yè)面

@RequestMapping('/login') public String login(String username,String password,Model model){//獲得當(dāng)前的用戶Subject subject = SecurityUtils.getSubject();//封裝用戶數(shù)據(jù)UsernamePasswordToken taken = new UsernamePasswordToken(username,password);try{//執(zhí)行登陸操作，沒(méi)有發(fā)生異常就說(shuō)明登陸成功 subject.login(taken); return 'index';}catch (UnknownAccountException e){ model.addAttribute('msg','用戶名錯(cuò)誤'); return 'login';}catch (IncorrectCredentialsException e){ model.addAttribute('msg','密碼錯(cuò)誤'); return 'login';} }

最后去UserRealm.java配置認(rèn)證

//認(rèn)證 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {System.out.println('認(rèn)證');String name = 'root';String password = '123456';UsernamePasswordToken userToken = (UsernamePasswordToken) authenticationToken;if (!userToken.getUsername().equals(name)){ return null;//拋出異常 用戶名錯(cuò)誤那個(gè)異常}//密碼認(rèn)證，shiro自己做return new SimpleAuthenticationInfo('',password,''); }

自定義一個(gè)未授權(quán)跳轉(zhuǎn)頁(yè)面

在ShiroConfig.java文件設(shè)置未授權(quán)時(shí)跳轉(zhuǎn)到unauthorized頁(yè)面，加入這行代碼：factoryBean.setUnauthorizedUrl('/unauthorized'); 2. 去Mycontroller寫(xiě)跳轉(zhuǎn)未授權(quán)頁(yè)面

@RequestMapping('/unauthorized') @ResponseBody//懶得寫(xiě)界面，返回一個(gè)字符串 public String unauthorized(){return '沒(méi)有授權(quán)，無(wú)法訪問(wèn)'; }

運(yùn)行效果：

從數(shù)據(jù)庫(kù)中接受用戶的權(quán)限，進(jìn)行判斷

在數(shù)據(jù)庫(kù)中添加一個(gè)屬性perms，相應(yīng)的實(shí)體類也要修改

修改UserRealm.java

package com.example.config;import com.example.pojo.User;import com.example.service.UserService;import org.apache.shiro.SecurityUtils;import org.apache.shiro.authc.*;import org.apache.shiro.authz.AuthorizationInfo;import org.apache.shiro.authz.SimpleAuthorizationInfo;import org.apache.shiro.realm.AuthorizingRealm;import org.apache.shiro.subject.PrincipalCollection;import org.apache.shiro.subject.Subject;import org.springframework.beans.factory.annotation.Autowired;public class UserRealm extends AuthorizingRealm { @Autowired UserService userService; //授權(quán) @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {System.out.println('授權(quán)');SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();//沒(méi)有使用數(shù)據(jù)庫(kù)，直接自己設(shè)置的用戶權(quán)限，給每個(gè)人都設(shè)置了，現(xiàn)實(shí)中要從數(shù)據(jù)庫(kù)中取//info.addStringPermission('user:add');//從數(shù)據(jù)庫(kù)中得到權(quán)限信息//獲得當(dāng)前登錄的對(duì)象Subject subject = SecurityUtils.getSubject();//拿到User對(duì)象，通過(guò)getPrincipal()獲得User currentUser = (User) subject.getPrincipal();//設(shè)置當(dāng)前用戶的權(quán)限info.addStringPermission(currentUser.getPerms());return info; } //認(rèn)證 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {System.out.println('認(rèn)證');UsernamePasswordToken userToken = (UsernamePasswordToken) authenticationToken;//連接真實(shí)的數(shù)據(jù)庫(kù)User user = userService.getUserByName(userToken.getUsername());if (user==null){ return null;//拋出異常 用戶名錯(cuò)誤那個(gè)異常}//密碼認(rèn)證，shiro自己做return new SimpleAuthenticationInfo(user,user.getPwd(),''); }}

有了授權(quán)后，就又出現(xiàn)了一個(gè)問(wèn)題，我們是不是要讓用戶沒(méi)有權(quán)限的東西，就看不見(jiàn)呢？這時(shí)候，就出現(xiàn)了Shiro-thymeleaf整合

Shiro-thymeleaf整合

導(dǎo)入整合的依賴

<!-- https://mvnrepository.com/artifact/com.github.theborakompanioni/thymeleaf-extras-shiro --><dependency> <groupId>com.github.theborakompanioni</groupId> <artifactId>thymeleaf-extras-shiro</artifactId> <version>2.0.0</version></dependency>

在ShiroConfig整合ShiroDialect

//整合ShiroDialect： 用來(lái)整合 shiro thymeleaf @Bean public ShiroDialect getShiroDialect(){return new ShiroDialect(); }

修改index頁(yè)面

<html lang='en' xmlns:th='http://www.thymeleaf.org' xmlns:shiro='http://www.thymeleaf.org/thymeleaf-extras-shiro'><!-- 三個(gè)命名空間xmlns:th='http://www.thymeleaf.org'xmlns:sec='http://www.thymeleaf.org/extras/spring-security'xmlns:shiro='http://www.thymeleaf.org/thymeleaf-extras-shiro'--><head> <meta charset='UTF-8'> <title>首頁(yè)</title></head><body><h1>首頁(yè)</h1><p th:text='${msg}'></p><!--判斷是否有用戶登錄，如果有就不顯示登錄按鈕--><div th:if='${session.loginUser==null}'> <a th:href='http://www.piao2010.com/bcjs/@{/toLogin}' rel='external nofollow' >登錄</a></div><div shiro:hasPermission='user:add'> <a th:href='http://www.piao2010.com/bcjs/@{/user/add}' rel='external nofollow' rel='external nofollow' rel='external nofollow' >add</a></div><div shiro:hasPermission='user:update'> <a th:href='http://www.piao2010.com/bcjs/@{/user/update}' rel='external nofollow' rel='external nofollow' rel='external nofollow' >update</a></div></body></html>

判斷是否有用戶登錄

//這個(gè)是整合shiro和thymeleaf用到的，讓登錄按鈕消失的判斷Subject subject = SecurityUtils.getSubject();Session session = subject.getSession();session.setAttribute('loginUser', user);

測(cè)試
