1.1shiro的作用

认证、授权、加密、会话管理、Web集成、缓存

1.2shiro的名词

#FormatImgID_0#

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 管理,验证某个人已经登录的人是否拥有某些权限

Session Management:会话管理,即用户登录后就是一次会话,在没有退出之前所有的信息都是在会话中。。

Cryptography:加密,保护数据的安全性,密码加密

Web Support:Web支持,可以非常容易的集成到web环境

Caching:缓存,比如用户登录之后,他的用户信息,权限不必每次去查

Concurrency:shiro支持多线程应用兵法验证,即如果在一个线程中开启另外一个线程,权限会自动传递过去

Testing:提供测试支持

Run AS:允许一个用户假装另一个用户(如果他们允许)的身份进行访问

Remember Me:记住我,这是一个常见的功能,即一次登录后,下次再来的话就不用登录了

记住一点,Shiro不会去维护用户、维护权限:这些需要我们自己去设计/提供,然后通过相应的接口注入给Shiro即可!

1.3shiro的架构

#FormatImgID_1#

Subject,Subject其实代表的就是当前正在执行操作的用户,只不过因为“User”一般指代人,但是一个“Subject”可以是人,也可以是任何的第三方系统,服务账号等任何其他正在和当前系统交互的第三方软件系统。

所有的Subject实例都被绑定到一个SecurityManager,如果你和一个Subject交互,所有的交互动作都会被转换成Subject与SecurityManager的交互。

SecurityManager。SecurityManager是Shiro的核心,他主要用于协调Shiro内部各种安全组件,不过我们一般不用太关心SecurityManager,对于应用程序开发者来说,主要还是使用Subject的API来处理各种安全验证逻辑。

Realm,这是用于连接Shiro和客户系统的用户数据的桥梁。一旦Shiro真正需要访问各种安全相关的数据(比如使用用户账户来做用户身份验证以及权限验证)时,他总是通过调用系统配置的各种Realm来读取数据。

2.SpringBoot集成shiro的步骤

2.1添加maven依赖

org.apache.shiro

shiro-core

1.4.0

org.apache.shiro

shiro-web

1.4.0

org.apache.shiro

shiro-ehcache

1.4.0

org.apache.shiro

shiro-spring

1.4.0

com.github.theborakompanioni

thymeleaf-extras-shiro

2.0.0

2.2新建缓存文件

ehcache-shiro.xml

timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="false"

diskPersistent="false" diskExpiryThreadIntervalSeconds="120"

memoryStoreEvictionPolicy="LRU"/>

maxElementsInMemory="10000" overflowToDisk="false" timeToIdleSeconds="0"

timeToLiveSeconds="0" statistics="true"/>

2.3重要的shiro配置类

不需要完全记住,只需要修改其中的一小部分

import at.pollux.thymeleaf.shiro.dialect.ShiroDialect;

import org.apache.shiro.spring.LifecycleBeanPostProcessor;

import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;

import org.apache.shiro.spring.web.ShiroFilterFactoryBean;

import org.apache.shiro.web.mgt.CookieRememberMeManager;

import org.apache.shiro.web.mgt.DefaultWebSecurityManager;

// 过滤链定义,从上向下顺序执行,一般将 /**放在最为下边

//

filterChainDefinitionMap.put("/**", "authc");

//配置记住我或认证通过可以访问的地址

filterChainDefinitionMap.put("/index", "user");

// filterChainDefinitionMap.put("/", "user");

System.out.println("Shiro拦截器工厂类注入成功");

shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);

return shiroFilterFactoryBean;

}

4.核心的授权认证类

import com.example.echart.entity.Permission;

import com.example.echart.entity.Role;

import com.example.echart.entity.User;

import com.example.echart.mapper.UserRoleMapper;

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.session.Session;

import org.apache.shiro.session.mgt.eis.SessionDAO;

import org.apache.shiro.subject.PrincipalCollection;

import org.apache.shiro.subject.support.DefaultSubjectContext;

import org.apache.shiro.web.session.mgt.DefaultWebSessionManager;

import org.springframework.beans.factory.annotation.Autowired;

import java.util.ArrayList;

import java.util.Collection;

import java.util.List;

/**

* @ Author :Zgq

* @ Date :Created in 18:19 2019/6/11

* @ Description:Shiro中最主要的代码,核心代码,用户认证授权处

* @ Modified By:

* @Version: $

*/

public class ShiroRealm extends AuthorizingRealm {

@Autowired

private SessionDAO sessionDAO;

@Autowired

private UserRoleMapper userRoleMapper;

@Override

protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection auth) {

//授权

String username = (String)auth.getPrimaryPrincipal();

System.out.println("进入到授权Realm中:"+username);

List dbroleList = userRoleMapper.selectRoleList(username);

List roleList=new ArrayList();

for(Role r:dbroleList){

roleList.add(r.getCode());

}

List dbpermissions = userRoleMapper.selectPermissionList(username);

List permissionList=new ArrayList();

for(Permission p:dbpermissions){

permissionList.add(p.getPermission());

}

// roleList.add("ADMIN");

// roleList.add("USER");

// List permissionList=new ArrayList();

// permissionList.add("ADMIN:USER:UPDATA");

// permissionList.add("ADMIN:USER:DELETE");

SimpleAuthorizationInfo simpleAuthorizationInfo=new SimpleAuthorizationInfo();

simpleAuthorizationInfo.addRoles(roleList);

simpleAuthorizationInfo.addStringPermissions(permissionList);

return simpleAuthorizationInfo;

}

@Override

protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken auth) throws AuthenticationException {

//认证

String username = (String)auth.getPrincipal();

System.out.println("进入到认证Realm中:"+username);

//在认证之前判断当前登录用户,只允许一个账号登录

Collection sessions = sessionDAO.getActiveSessions();

for (Session session : sessions){

String loginedUsername = String.valueOf(session.getAttribute(DefaultSubjectContext.PRINCIPALS_SESSION_KEY));

if(username.equals(loginedUsername)){

session.setTimeout(0);

break;

}

}

//通过username在数据库中查询用户,判断密码

User dbuser = userRoleMapper.selectByUserName(username);

//通过用户名在数据库中拿到,判断用户名和密码对不对

if(dbuser!=null){

SimpleAuthenticationInfo authInfo = new SimpleAuthenticationInfo(username, dbuser.getPwd(), "userRealm");

return authInfo;

}

return null;

}

}

5.登录的Controller类,LoginController

import org.apache.shiro.SecurityUtils;

import org.apache.shiro.authc.UsernamePasswordToken;

import org.apache.shiro.crypto.hash.Md5Hash;

import org.apache.shiro.subject.Subject;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import java.util.Map;

/**

* @ Author :Zgq

* @ Date :Created in 10:30 2019/6/12

* @ Description:登录层方法

* @ Modified By:

* @Version: $

*/

@Controller

public class LoginController {

//登录页面

@RequestMapping(value = {"/login"})

public String login(Map map) {

map.put("msg","请登录");

return "/shiro/login-page";

}

//登录成功页面

@RequestMapping(value = {"/index"})

public String index(Map map) {

map.put("msg","登录成功");

//获取用户信息

Subject subject = SecurityUtils.getSubject();

String username = (String)subject.getPrincipal();

map.put("username",username);

return "/shiro/index";

}

//登录请求

@RequestMapping(value = {"/userLogin"})

public String userLogin(String username, String pwd,boolean rememberMe, Map map)

{无锡人流医院 http://xmobile.wxbhnk120.com/

Subject subject = SecurityUtils.getSubject();

//根据自己盐加密的方式,放入密码

String encodePwd = new Md5Hash(pwd, username).toString();

UsernamePasswordToken auth = new UsernamePasswordToken(username, encodePwd,rememberMe);

try {

subject.login(auth);

return "redirect:/index";

}catch (Exception e){

e.printStackTrace();

map.put("msg","账号或密码错误");

return "redirect:/login";

}

}

//退出登录

@RequestMapping(value = {"/loginOut"})

public String loginOut(Map map) {

//获取用户信息

Subject subject = SecurityUtils.getSubject();

subject.logout();

map.put("msg","退出登录");

return "redirect:/login";

}

/**

* 加密的测试

* @param args

*/

public static void main(String[] args) {

//加密

String zhouguoqing = new Md5Hash("111", "admin1").toString();

System.out.println(zhouguoqing);

}

}

6.因为是和数据库直接对接的,所以我也新建了一个UserRoleMapper接口,返回数据

import com.example.echart.entity.Permission;

import com.example.echart.entity.Role;

import com.example.echart.entity.User;

import org.apache.ibatis.annotations.Mapper;

import org.apache.ibatis.annotations.Select;

import org.springframework.stereotype.Component;

import java.util.List;

@Mapper

@Component

public interface UserRoleMapper {

/**

* 通过登录名查询信息

* @param username

* @return

* @throws Exception

*/

@Select("select * from t_user where username=#{username} limit 1")

User selectByUserName(String username);

/**

* 通过用户名查询用户角色信息

* @param username

* @return

* @throws Exception

*/

@Select("select * from t_user u,t_role r,t_user_role ur where u.username=#{username} and ur.userId=u.id and ur.roleId=r.id")

List selectRoleList(String username);

/**

* 通过用户名查找用户权限

* @param username

* @return

*/

@Select("select * from t_permission p \n" +

"where p.id in(\n" +

"\tselect permissionId from t_role_permission rp \n" +

"\twhere rp.roleId in (\n" +

"\t\t\tselect ur.roleId from t_user_role ur where userId in(\n" +

"\t\t\tselect u.id from t_user u where u.username=#{username}\n" +

"\t\t\t)\n" +

"\t)\n" +

")")

List selectPermissionList(String username);

}

7.前台页面thymeleaf的展示

xmlns:shiro="http://www.w3.org/1999/xhtml">

你好:

ADMIN角色

USER角色

SUPERMAN角色

UPDATA权限

DELETE权限

INSERT权限

SELECT权限

3.完成的效果

#FormatImgID_3#

用不同用户登录之后会自动获取登录用户的角色和权限信息
