3.3 创建项目包结构

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-NNuns5Pt-1604249108145)(img/shiro02.png)]

3.4 配置初始化文件application.yml

#配置服务端口号
server:
 port: 8080
#配置数据源
spring:
 datasource:
 type: com.alibaba.druid.pool.DruidDataSource
 driver-class-name: com.mysql.jdbc.Driver
 url: jdbc:mysql://localhost:3306/my_shiro?useUnicode=true&characterEncoding=utf-8
 username: root
 password: 59852369
#配置mybatis
mybatis:
 mapper-locations: classpath:mapper/*.xml
 type-aliases-package: com.qf.domain.pojo

四、程序设计开发

4.1 实体类开发

​ SysUser.java

package com.qf.domain;

import lombok.Data;

import java.io.Serializable;
import java.util.Date;
/**
 * Created by 54110 on 2019-07-05.
 */
@Data
public class SysUser implements Serializable {
 private int userId;//用户id
 private String loginName;//登录名
 private String password;//
 private Integer state;
 private Date createTime;
 private String realname;

}

SysPermission.java

package com.qf.domain;

import lombok.Data;

import java.io.Serializable;

/**
 * Created by 54110 on 2019-07-05.
 */
@Data
public class SysPermission implements Serializable {
 private int permId;
 private String permName;//权限名称
 private String permUrl;//权限操作地址(路径)
 private String menuName;//菜单名
 private String menuLevel;//菜单级别(11:一级;12:二级。。。)
 private String menuCode;//菜单编码(每级两位数字)
 private int ifValid;
 private String parentCode;
}

4.2 数据访问层接口开发

SysUserMapper.java

package com.qf.mapper;

import com.qf.domain.SysUser;
import org.apache.ibatis.annotations.Mapper;

/**
 * Created by 54110 on 2019-07-05.
 */
@Mapper
public interface SysUserMapper {
 public SysUser findUserByUsername(String username);
}

SysPermissionMapper

package com.qf.mapper;

import com.qf.domain.SysPermission;
import org.apache.ibatis.annotations.Mapper;

import java.util.List;

/**
 * Created by 54110 on 2019-07-05.
 */
@Mapper
public interface SysPermissionMapper {
 //	根据用户登录名查询其所拥有的权限
 public List<SysPermission> findPermissionsByLoginName(String loginName);
}

4.3 Mybatis映射开发

SysUsersMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
  PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.qf.mapper.SysUserMapper">
 <resultMap type="com.qf.domain.SysUser" id="userMap">
  <id column="USERID" property="userid" />
  <result column="LOGIN_NAME" property="loginName" />
  <result column="PASSWORD" property="password" />
  <result column="STATE" property="state" />
  <result column="CREATE_TIME" property="createTime" />
  <result column="REALNAME" property="realname" />
 </resultMap>

 <sql id="tbusers_columns">
  PASSWORD,LOGIN_NAME,CREATE_TIME,REALNAME,STATE
 </sql>
 <!--根据用户名查询对象 -->
 <select id="findUserByUsername" parameterType="string" resultMap="userMap">
  SELECT
  <include refid="tbusers_columns"></include>
  FROM
  TB_SYS_USER US
  WHERE
  US.LOGIN_NAME = #{name}
 </select>
</mapper>

SysPermissionMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
  PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.qf.mapper.SysPermissionMapper">
 <resultMap type="com.qf.domain.SysPermission" id="permMap">
  <id column="PERMISSION_ID" property="permId" />
  <result column="PER_NAME" property="permName" />
  <result column="MENU_URL" property="permUrl" />
  <result column="MENU_NAME" property="menuName" />
  <result column="MENU_TYPE" property="menuLevel" />
  <result column="MENU_CODE" property="menuCode" />
  <result column="PARENT_CODE" property="parentCode" />
  <result column="IF_ViLID" property="ifValid" />

 </resultMap>

 <select id="findPermissionsByLoginName" parameterType="string" resultMap="permMap">

  SELECT
  p.*
  FROM
  TB_SYS_USER us ,
  TB_USER_ROLE ur,
  TB_SYS_ROLE r,
  TB_ROLE_PERMISSION rp,
  TB_SYS_PERMISSION p
  WHERE
  us.USERID = ur.USER_ID AND ur.ROLE_ID = r.ROLE_ID
  AND r.ROLE_ID = rp.ROLE_ID AND rp.PERMISSION_ID = p.PERMISSION_ID
  AND trim(us.LOGIN_NAME) = #{loginName}
  ORDER BY p.MENU_CODE

 </select>
</mapper>

4.4 业务层开发

SysUsersServiceImpl.java

package com.qf.service.impl;

import com.qf.domain.SysUser;
import com.qf.mapper.SysUserMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * Created by 54110 on 2019-07-05.
 */
@Service
public class SysUsersServiceImpl {

  @Autowired
  private SysUserMapper userMapper;
  
  public SysUser queryUserByLoginName(String loginName) {

   SysUser tbUsers = userMapper.findUserByUsername(loginName);
   return tbUsers;
  }

}

​SysPermissionServiceImpl.java

package com.qf.service.impl;

import com.qf.domain.SysPermission;
import com.qf.mapper.SysPermissionMapper;
import com.qf.service.SysPermissionService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * Created by 54110 on 2019-07-05.
 */
@Service
public class SysPermissionServiceImpl implements SysPermissionService {

 @Autowired
 private SysPermissionMapper permMapper;
 @Override
 public List<SysPermission> queryPermissionsByLoginName(String loginName) {
  List<SysPermission> list = permMapper.findPermissionsByLoginName(loginName);
  return list;
 }

}

4.5 控制层接口开发

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.
 */
@Controller
public class UserController {
 @Autowired
 private SysUserService userService;
 // 登录页(view)展示
 @RequestMapping("/login")
 public String showlogin(){
  return "login";
 }

 /**
  * 登录处理
  * @param map 用户登录表单数据
  * @return 逻辑视图
  */
 @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();//从安全管理器中获取主体对象
   UsernamePasswordToken token = new UsernamePasswordToken();//构建令牌对象
   token.setUsername(map.get("name").toString());//赋身份信息
   token.setPassword(map.get("password").toString().toCharArray());//赋凭证信息
   subject.login(token);//使用主体的login方法判定用户的权限
   if(subject.isAuthenticated()){
    //  已登陆
    //  用户信息及权限信息的存储(session|| redis)
    return "main";
   }
  } catch (AuthenticationException e) {
   e.printStackTrace();
   System.out.println("登录失败");
  }
  return "login";
 }
 // 登录且拥有user:
 @RequestMapping("/one")
 public String showCaseOne(){
  return "one";
 }
 @RequestMapping("/two")
 public String showCaseTwo(){
  return "two";
 }
 // 权限不足时,响应的页面
 @RequestMapping("/unauth")
 public String showPermission(){
  return "unauth";
 }
 // 用户注销操作
 @RequestMapping("/logout")
 public String logout(){
  Subject subject = SecurityUtils.getSubject();
  subject.logout();//登出
  return "redirect:login";
 }
}

4.6 关于shiro的开发

a、自定义安全策略

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;

 // 系统授权
 @Override
 protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
  Subject subject = SecurityUtils.getSubject();//获取主体对象
  String username =(String ) subject.getPrincipal();//获取用户身份信息
  List<SysPermission> permissions = sysPermissionService.queryPermissionsByLoginName(username);//根据用户名获取用户的权限信息
//  权限去重
  Collection<String > perms = new HashSet<>();
  for (SysPermission perm: permissions ) {
   perms.add(perm.getPermName());
  }
  SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
  simpleAuthorizationInfo.addStringPermissions(perms);//授权
  return simpleAuthorizationInfo;
 }
 //用户认证
 @Override
 protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
  String username = (String) token.getPrincipal();//获取用户信息

  //根据用户信息查询数据库获取后端的用户身份,转交给securityManager判定
  SysUser user1 = sysUserService.queryUserByLoginName(username);//从数据库直接取
  System.out.println(user1);
  if(user1!=null) {
   SimpleAuthenticationInfo simpleAuthenticationInfo = new SimpleAuthenticationInfo(user1.getLoginName(), user1.getPassword(), getName());
   return simpleAuthenticationInfo;
  }
  return null;
 }
}

b、自定义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.
 */
@Configuration
public 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"); //必须登录才可访问
  map.put("/one","perms[user_edit]");//只有特定权限(“user_edit”)的用户登录后才可访问
  map.put("/two","perms[user_forbidden]");//只有特定权限(“user_forbidden”)的用户登录后才可访问
  shiroFilterFactoryBean.setLoginUrl("/login");//设置登录页(匿名)
  shiroFilterFactoryBean.setUnauthorizedUrl("/unauth");//权限不足的错误提示页
  shiroFilterFactoryBean.setFilterChainDefinitionMap(map);//装配拦截策略
  return shiroFilterFactoryBean;
 }
 // 配置安全管理器(注入Realm对象)
 @Bean(name="defaultWebSecurityManager")
 public DefaultWebSecurityManager defaultWebSecurityManager(@Qualifier("myShiroRealm") MyShiroRealm myShiroRealm){
  DefaultWebSecurityManager defaultWebSecurityManager = new DefaultWebSecurityManager();
  defaultWebSecurityManager.setRealm(myShiroRealm);
  return defaultWebSecurityManager;
 }

 @Bean(name="myShiroRealm") //使用该注解是的Realm对象由spring容器管理
 public MyShiroRealm myShiroRealm(){
  MyShiroRealm shiroRealm = new MyShiroRealm();
  return shiroRealm;
 }
}

五、功能测试

​ 地址栏输入http://localhost:8080/login

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-BdyHhsoT-1604249108147)(img\shiro03.png)]

​ 使用用户:admin密码:admin登录,登录成功后显示页面如下:

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-LdoaSOGM-1604249108149)(img/shiro04.png)]

​ 因为admin2用户拥有case one功能的操作权限,所以当鼠标单击case one链接时,显示如下成功访问页面

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-Co1rUWJi-1604249108150)(img/shiro05.png)]

因为admin2没有case two访问权限,当用户单击case two时,会显示无权限访问的页面:

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-geha4PCi-1604249108150)(img/shiro06.png)]

当单击logout链接时,系统重回登录页。此时使用用户test2密码test2再次登录。因test2用户无case one权限,有case two权限,所以当test2用户单击case two时会显示如下页面:

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-AWZrOeGj-1604249108151)(img/shiro07.png)]

六、启动shiro注解模式

6.1、在ShiroConfig.java中注释掉原先使用路径过滤的权限拦截语句:

//只有特定权限(“user_edit”)的用户登录后才可访问
// map.put("/one","perms[user_edit]");
//只有特定权限(“user_forbidden”)的用户登录后才可访问
// map.put("/two","perms[user_forbidden]");

6.2、修改ShiroConfig.java类代码添加如下内容:

/**
  * 开启Shiro注解(如@RequiresRoles,@RequiresPermissions),
  * 需借助SpringAOP扫描使用Shiro注解的类,并在必要时进行安全逻辑验证
  * 配置以下两个bean(DefaultAdvisorAutoProxyCreator和AuthorizationAttributeSourceAdvisor)
  */
 @Bean
 public DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator(){
  DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator();
  advisorAutoProxyCreator.setProxyTargetClass(true);
  return advisorAutoProxyCreator;
 }
 /**
  * 开启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控制器接口代码:

// 登录且拥有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、测试

此事有权限访问的也页面正常,但未授权的页面,无法进入提示页,显示如下:

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-pM9lRu2Z-1604249108152)(img/shiro08.png)]

​ 后台亦抛出org.apache.shiro.authz.AuthorizationException异常:

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-k8KTUuoi-1604249108152)(img/shiro09.png)]

6.5、此时使用aop拦截抛出的异常

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.
 */
@ControllerAdvice
public class ExceptionController {

 @ExceptionHandler(value = UnauthorizedException.class)//处理访问方法时权限不足问题
 public String defaultErrorHandler(HttpServletRequest req, Exception e) {
  return "unauth";
 }
}

七、shiro密码的MD5加密处理

 7.1.密码的加密

在数据表中存的密码不应该是12345,而应该是12345加密之后的字符串,而且还要求这个加密算法是不可逆的,即由加密后的字符串不能反推回来原来的密码,如果能反推回来那这个加密是没有意义的。

著名的加密算法,比如 MD5,SHA1

7.2.MD5加密

1). 如何把一个字符串加密为MD5

2). 使用MD5加密算法后,前台用户输入的字符串如何使用MD5加密,需要做的是将当前的Realm 的credentialsMatcher属性,替换为Md5CredentialsMatcher 由于Md5CredentialsMatcher已经过期了,推荐使用HashedCredentialsMatcher 并设置加密算法即可。

7.3.使用MD5加密

1). 修改ShiroConfig.java文件添加如下内容;

 /**
  * 密码校验规则HashedCredentialsMatcher
  * 这个类是为了对密码进行编码的 ,
  * 防止密码在数据库里明码保存 , 当然在登陆认证的时候 ,
  * 这个类也负责对form里输入的密码进行编码
  * 处理认证匹配处理器:如果自定义需要实现继承HashedCredentialsMatcher
  */
 @Bean("hashedCredentialsMatcher")
 public HashedCredentialsMatcher hashedCredentialsMatcher() {
  HashedCredentialsMatcher credentialsMatcher = new HashedCredentialsMatcher();
  //指定加密方式为MD5
  credentialsMatcher.setHashAlgorithmName("MD5");
  //加密次数
  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的认证逻辑如下:

//用户认证
 @Override
 protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
  String username = (String) token.getPrincipal();//获取用户信息

  SysUser user1 = sysUserService.queryUserByLoginName(username);//从数据库直接取
  System.out.println(user1);
  if(user1!=null) {
   //当前realm对象的name
   String realmName = getName();
   //盐值
   ByteSource credentialsSalt = ByteSource.Util.bytes(username);
   //封装用户信息,构建AuthenticationInfo对象并返回
   AuthenticationInfo authcInfo = new SimpleAuthenticationInfo(username, user1.getPassword(), credentialsSalt, realmName);
   return authcInfo;

  }
  return null;
 }

​ 3). 通过 new SimpleHash(hashAlgorithmName, credentials, salt, hashIterations); 我们可以得到"12345"经过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";//登陆时的密码
  int hashIterations =1024;//加密次数
  ByteSource credentialsSalt = ByteSource.Util.bytes("admin2");//使用登录名做为salt
  SimpleHash simpleHash = new SimpleHash(hashAlgorithName, password, credentialsSalt, hashIterations);
  System.out.println("ok "+simpleHash);
 }

}

​ 使用密文替换数据库中的明文密码;

7.4 测试 略。。。。

7.5 后记 为什么使用 MD5 盐值加密: 希望即使两个原始密码相同,加密得到的两个字符串也不同。

为什么使用 MD5 盐值加密:
希望即使两个原始密码相同,加密得到的两个字符串也不同。
如何做到:
1). 在 doGetAuthenticationInfo 方法返回值创建 SimpleAuthenticationInfo 对象的时候, 需要使用SimpleAuthenticationInfo(principal, credentials, credentialsSalt, realmName) 构造器
2). 使用 ByteSource.Util.bytes() 来计算盐值.
3). 盐值需要唯一: 一般使用随机字符串或 user id
4). 使用 new SimpleHash(hashAlgorithmName, credentials, salt, hashIterations); 来计算盐值加密后的密码的值.
