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"/>

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
