​ SysUser.java

package com.qf.domain;import lombok.Data;import java.io.Serializable;import java.util.Date;/** * Created by 54110 on 2019-07-05. */@Datapublic class SysUser implements Serializable { private int userId;//用戶id private String loginName;//登錄名 private String password;// private Integer state; private Date createTime; private String realname;}

UserController.java

package com.qf.controller;import com.qf.service.SysUserService;import org.apache.shiro.SecurityUtils;import org.apache.shiro.authc.AuthenticationException;import org.apache.shiro.authc.UsernamePasswordToken;import org.apache.shiro.subject.Subject;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RequestParam;import java.util.Map;/** * Created by 54110 on 2019-07-05. */@Controllerpublic class UserController { @Autowired private SysUserService userService; // 登錄頁(view)展示 @RequestMapping('/login') public String showlogin(){ return 'login'; } /** * 登錄處理 * @param map 用戶登錄表單數(shù)據(jù) * @return 邏輯視圖 */ @RequestMapping(value='dealLogin' ,method= RequestMethod.POST) public String dealLogin(@RequestParam Map<String,Object> map){ System.out.println( map.values().toString()); try { Subject subject = SecurityUtils.getSubject();//從安全管理器中獲取主體對(duì)象 UsernamePasswordToken token = new UsernamePasswordToken();//構(gòu)建令牌對(duì)象 token.setUsername(map.get('name').toString());//賦身份信息 token.setPassword(map.get('password').toString().toCharArray());//賦憑證信息 subject.login(token);//使用主體的login方法判定用戶的權(quán)限 if(subject.isAuthenticated()){ // 已登陸 // 用戶信息及權(quán)限信息的存儲(chǔ)（session|| redis） return 'main'; } } catch (AuthenticationException e) { e.printStackTrace(); System.out.println('登錄失敗'); } return 'login'; } // 登錄且擁有user： @RequestMapping('/one') public String showCaseOne(){ return 'one'; } @RequestMapping('/two') public String showCaseTwo(){ return 'two'; } // 權(quán)限不足時(shí)，響應(yīng)的頁面 @RequestMapping('/unauth') public String showPermission(){ return 'unauth'; } // 用戶注銷操作 @RequestMapping('/logout') public String logout(){ Subject subject = SecurityUtils.getSubject(); subject.logout();//登出 return 'redirect:login'; }}4.6 關(guān)于shiro的開發(fā)

a、自定義安全策略

MyShiroRealm.java

package com.qf.shiro;import com.qf.domain.SysPermission;import com.qf.domain.SysUser;import com.qf.service.SysPermissionService;import com.qf.service.SysUserService;import org.apache.shiro.SecurityUtils;import org.apache.shiro.authc.AuthenticationException;import org.apache.shiro.authc.AuthenticationInfo;import org.apache.shiro.authc.AuthenticationToken;import org.apache.shiro.authc.SimpleAuthenticationInfo;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;import java.util.Collection;import java.util.HashSet;import java.util.List;/** * Created by 54110 on 2019-07-05. */public class MyShiroRealm extends AuthorizingRealm { @Autowired private SysUserService sysUserServiceImpl; @Autowired private SysPermissionService sysPermissionServiceImpl; private String username; // 系統(tǒng)授權(quán) @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { Subject subject = SecurityUtils.getSubject();//獲取主體對(duì)象 String username =(String ) subject.getPrincipal();//獲取用戶身份信息 List<SysPermission> permissions = sysPermissionService.queryPermissionsByLoginName(username);//根據(jù)用戶名獲取用戶的權(quán)限信息// 權(quán)限去重 Collection<String > perms = new HashSet<>(); for (SysPermission perm: permissions ) { perms.add(perm.getPermName()); } SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo(); simpleAuthorizationInfo.addStringPermissions(perms);//授權(quán) return simpleAuthorizationInfo; } //用戶認(rèn)證 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { String username = (String) token.getPrincipal();//獲取用戶信息 //根據(jù)用戶信息查詢數(shù)據(jù)庫獲取后端的用戶身份，轉(zhuǎn)交給securityManager判定 SysUser user1 = sysUserService.queryUserByLoginName(username);//從數(shù)據(jù)庫直接取 System.out.println(user1); if(user1!=null) { SimpleAuthenticationInfo simpleAuthenticationInfo = new SimpleAuthenticationInfo(user1.getLoginName(), user1.getPassword(), getName()); return simpleAuthenticationInfo; } return null; }}

b、自定義Shiro配置管理

ShiroConfig.java

package com.qf.config;import com.qf.shiro.MyShiroRealm;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.HashMap;import java.util.Map;/** * Created by 54110 on 2019-07-05. */@Configurationpublic class ShiroConfig { @Bean public ShiroFilterFactoryBean shiroFilterFactoryBean(@Qualifier('defaultWebSecurityManager') DefaultWebSecurityManager defaultWebSecurityManager){ ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean(); shiroFilterFactoryBean.setSecurityManager(defaultWebSecurityManager); Map<String ,String> map = new HashMap<>(); map.put('/main','authc'); //必須登錄才可訪問 map.put('/one','perms[user_edit]');//只有特定權(quán)限（“user_edit”）的用戶登錄后才可訪問 map.put('/two','perms[user_forbidden]');//只有特定權(quán)限（“user_forbidden”）的用戶登錄后才可訪問 shiroFilterFactoryBean.setLoginUrl('/login');//設(shè)置登錄頁（匿名） shiroFilterFactoryBean.setUnauthorizedUrl('/unauth');//權(quán)限不足的錯(cuò)誤提示頁 shiroFilterFactoryBean.setFilterChainDefinitionMap(map);//裝配攔截策略 return shiroFilterFactoryBean; } // 配置安全管理器（注入Realm對(duì)象） @Bean(name='defaultWebSecurityManager') public DefaultWebSecurityManager defaultWebSecurityManager(@Qualifier('myShiroRealm') MyShiroRealm myShiroRealm){ DefaultWebSecurityManager defaultWebSecurityManager = new DefaultWebSecurityManager(); defaultWebSecurityManager.setRealm(myShiroRealm); return defaultWebSecurityManager; } @Bean(name='myShiroRealm') //使用該注解是的Realm對(duì)象由spring容器管理 public MyShiroRealm myShiroRealm(){ MyShiroRealm shiroRealm = new MyShiroRealm(); return shiroRealm; }}五、功能測(cè)試

​ 地址欄輸入http://localhost:8080/login

​ 使用用戶：admin密碼：admin登錄，登錄成功后顯示頁面如下：

​ 因?yàn)閍dmin2用戶擁有case one功能的操作權(quán)限，所以當(dāng)鼠標(biāo)單擊case one鏈接時(shí)，顯示如下成功訪問頁面

[外鏈圖片轉(zhuǎn)存失敗,源站可能有防盜鏈機(jī)制,建議將圖片保存下來直接上傳(img-Co1rUWJi-1604249108150)(img/shiro05.png)]

因?yàn)閍dmin2沒有case two訪問權(quán)限，當(dāng)用戶單擊case two時(shí)，會(huì)顯示無權(quán)限訪問的頁面：

當(dāng)單擊logout鏈接時(shí)，系統(tǒng)重回登錄頁。此時(shí)使用用戶test2密碼test2再次登錄。因test2用戶無case one權(quán)限，有case two權(quán)限，所以當(dāng)test2用戶單擊case two時(shí)會(huì)顯示如下頁面：

[外鏈圖片轉(zhuǎn)存失敗,源站可能有防盜鏈機(jī)制,建議將圖片保存下來直接上傳(img-AWZrOeGj-1604249108151)(img/shiro07.png)]

六、啟動(dòng)shiro注解模式6.1、在ShiroConfig.java中注釋掉原先使用路徑過濾的權(quán)限攔截語句：

//只有特定權(quán)限（“user_edit”）的用戶登錄后才可訪問// map.put('/one','perms[user_edit]');//只有特定權(quán)限（“user_forbidden”）的用戶登錄后才可訪問// map.put('/two','perms[user_forbidden]');6.2、修改ShiroConfig.java類代碼添加如下內(nèi)容：

/** * 開啟Shiro注解(如@RequiresRoles,@RequiresPermissions), * 需借助SpringAOP掃描使用Shiro注解的類,并在必要時(shí)進(jìn)行安全邏輯驗(yàn)證 * 配置以下兩個(gè)bean(DefaultAdvisorAutoProxyCreator和AuthorizationAttributeSourceAdvisor) */ @Bean public DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator(){ DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator(); advisorAutoProxyCreator.setProxyTargetClass(true); return advisorAutoProxyCreator; } /** * 開啟aop注解支持 */ @Bean public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(DefaultWebSecurityManager defaultWebSecurityManager) { AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor(); authorizationAttributeSourceAdvisor.setSecurityManager(defaultWebSecurityManager); return authorizationAttributeSourceAdvisor; }6.3、修改UserController.java控制器接口代碼：

// 登錄且擁有user： @RequiresPermissions(value={'user_edit'}) @RequestMapping('/one') public String showCaseOne(){ return 'one'; } @RequiresPermissions(value={'user_forbidden'}) @RequestMapping('/two') public String showCaseTwo(){ return 'two'; }6.4、測(cè)試

此事有權(quán)限訪問的也頁面正常，但未授權(quán)的頁面，無法進(jìn)入提示頁，顯示如下：

[外鏈圖片轉(zhuǎn)存失敗,源站可能有防盜鏈機(jī)制,建議將圖片保存下來直接上傳(img-pM9lRu2Z-1604249108152)(img/shiro08.png)]

​ 后臺(tái)亦拋出org.apache.shiro.authz.AuthorizationException異常：

[外鏈圖片轉(zhuǎn)存失敗,源站可能有防盜鏈機(jī)制,建議將圖片保存下來直接上傳(img-k8KTUuoi-1604249108152)(img/shiro09.png)]

6.5、此時(shí)使用aop攔截拋出的異常

package com.jeffrey.exception;import org.apache.shiro.authz.UnauthorizedException;import org.springframework.web.bind.annotation.ControllerAdvice;import org.springframework.web.bind.annotation.ExceptionHandler;import javax.servlet.http.HttpServletRequest;/** * Created by jeffrey on 2019/4/8. */@ControllerAdvicepublic class ExceptionController { @ExceptionHandler(value = UnauthorizedException.class)//處理訪問方法時(shí)權(quán)限不足問題 public String defaultErrorHandler(HttpServletRequest req, Exception e) { return 'unauth'; }}七、shiro密碼的MD5加密處理 7.1.密碼的加密

在數(shù)據(jù)表中存的密碼不應(yīng)該是12345，而應(yīng)該是12345加密之后的字符串，而且還要求這個(gè)加密算法是不可逆的，即由加密后的字符串不能反推回來原來的密碼，如果能反推回來那這個(gè)加密是沒有意義的。

著名的加密算法，比如 MD5，SHA1

7.2.MD5加密

1). 如何把一個(gè)字符串加密為MD5

2). 使用MD5加密算法后，前臺(tái)用戶輸入的字符串如何使用MD5加密，需要做的是將當(dāng)前的Realm 的credentialsMatcher屬性，替換為Md5CredentialsMatcher 由于Md5CredentialsMatcher已經(jīng)過期了，推薦使用HashedCredentialsMatcher 并設(shè)置加密算法即可。

7.3.使用MD5加密

1). 修改ShiroConfig.java文件添加如下內(nèi)容；

/** * 密碼校驗(yàn)規(guī)則HashedCredentialsMatcher * 這個(gè)類是為了對(duì)密碼進(jìn)行編碼的 , * 防止密碼在數(shù)據(jù)庫里明碼保存 , 當(dāng)然在登陸認(rèn)證的時(shí)候 , * 這個(gè)類也負(fù)責(zé)對(duì)form里輸入的密碼進(jìn)行編碼 * 處理認(rèn)證匹配處理器：如果自定義需要實(shí)現(xiàn)繼承HashedCredentialsMatcher */ @Bean('hashedCredentialsMatcher') public HashedCredentialsMatcher hashedCredentialsMatcher() { HashedCredentialsMatcher credentialsMatcher = new HashedCredentialsMatcher(); //指定加密方式為MD5 credentialsMatcher.setHashAlgorithmName('MD5'); //加密次數(shù) credentialsMatcher.setHashIterations(1024); credentialsMatcher.setStoredCredentialsHexEncoded(true); return credentialsMatcher; } @Bean('myShiroRealm') public MyShiroRealm myShiroRealm(@Qualifier('hashedCredentialsMatcher') HashedCredentialsMatcher matcher) { MyShiroRealm authRealm = new MyShiroRealm(); authRealm.setAuthorizationCachingEnabled(false); authRealm.setCredentialsMatcher(matcher); return authRealm; }

​ 2).修改MyRealm.java的認(rèn)證邏輯如下：

//用戶認(rèn)證 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { String username = (String) token.getPrincipal();//獲取用戶信息 SysUser user1 = sysUserService.queryUserByLoginName(username);//從數(shù)據(jù)庫直接取 System.out.println(user1); if(user1!=null) { //當(dāng)前realm對(duì)象的name String realmName = getName(); //鹽值 ByteSource credentialsSalt = ByteSource.Util.bytes(username); //封裝用戶信息，構(gòu)建AuthenticationInfo對(duì)象并返回 AuthenticationInfo authcInfo = new SimpleAuthenticationInfo(username, user1.getPassword(), credentialsSalt, realmName); return authcInfo; } return null; }

​ 3). 通過 new SimpleHash(hashAlgorithmName, credentials, salt, hashIterations); 我們可以得到'12345'經(jīng)過MD5 加密1024后的字符串；

package com.jeffrey;import org.apache.shiro.crypto.hash.SimpleHash;import org.apache.shiro.util.ByteSource;/** * Created by jeffrey on 2019/4/8. */public class MD5Salt { public static void main(String[] args){ String hashAlgorithName = 'MD5';//加密算法 String password = '12345';//登陸時(shí)的密碼 int hashIterations =1024;//加密次數(shù) ByteSource credentialsSalt = ByteSource.Util.bytes('admin2');//使用登錄名做為salt SimpleHash simpleHash = new SimpleHash(hashAlgorithName, password, credentialsSalt, hashIterations); System.out.println('ok '+simpleHash); }}

​ 使用密文替換數(shù)據(jù)庫中的明文密碼；

7.4 測(cè)試 略。。。。7.5 后記 為什么使用 MD5 鹽值加密: 希望即使兩個(gè)原始密碼相同，加密得到的兩個(gè)字符串也不同。

為什么使用 MD5 鹽值加密:希望即使兩個(gè)原始密碼相同，加密得到的兩個(gè)字符串也不同。如何做到:1). 在 doGetAuthenticationInfo 方法返回值創(chuàng)建 SimpleAuthenticationInfo 對(duì)象的時(shí)候, 需要使用SimpleAuthenticationInfo(principal, credentials, credentialsSalt, realmName) 構(gòu)造器2). 使用 ByteSource.Util.bytes() 來計(jì)算鹽值.3). 鹽值需要唯一: 一般使用隨機(jī)字符串或 user id4). 使用 new SimpleHash(hashAlgorithmName, credentials, salt, hashIterations); 來計(jì)算鹽值加密后的密碼的值.
