SpringBoot中关于Shiro权限管理的整合使用

 shiro是一个轻量级的安全框架,包含用户认证用户授权

分析shiro的核心API:

Subject:用户主体(把操作交给SecurityManager)

SecurityManager:安全管理器(管理Reaml)

Reaml:shiro连接数据的桥梁

 

 

Shiro的配置类:
 创建ShiroFilterFactoryBean;

 创建DefaultWebSecurityManager;

  创建Reaml(继承AuthorizingReaml);

 

Shiro内置过滤器,可以实现权限相关的拦截器:

 常用的过滤器:

anno:无需认证(登陆)可以访问

authc:必须认证才能访问

user:如果使用rememberMe的功能可以直接访问

perms:该资源必须得到资源权限可以访问

role:该资源必须得到角色权限才能访问

 

 

在整合Shiro的时候,我们先要确定一下我们的步骤:

1.加入Shiro的依赖包,实现自己的Realm类(通过继承AuthorizingRealm类);

2.实现Shiro的配置类

3.实现前端的登录界面以及Controller类

 

第一步:

在pom.xml中加入依赖包

<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring</artifactId>
    <version>1.4.0</version>
 </dependency>

实现Realm类

package ariky.shiro.realm;
 
import java.util.HashSet;
import java.util.Set;
 
import javax.servlet.http.HttpServletRequest;
 
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.IncorrectCredentialsException;
import org.apache.shiro.authc.LockedAccountException;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authc.UsernamePasswordToken;
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.util.ByteSource;
import org.apache.shiro.web.subject.WebSubject;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
 
/**
* @ClassName:
* @Description: Realm的配置
* @author fuweilian
* @date 2018-5-12 上午11:36:41
 */
public class MyShiroRealm extends AuthorizingRealm {
    //slf4j记录日志,可以不使用
    private Logger logger = LoggerFactory.getLogger(MyShiroRealm.class);
 
    /**
     * 设置授权信息
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        logger.info("开始授权(doGetAuthorizationInfo)");
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        HttpServletRequest request = (HttpServletRequest) ((WebSubject) SecurityUtils
                .getSubject()).getServletRequest();//这个可以用来获取在登录的时候提交的其他额外的参数信息
        String username = (String) principals.getPrimaryPrincipal();//这里是写的demo,后面在实际项目中药通过这个登录的账号去获取用户的角色和权限,这里直接是写死的
        //受理权限
        //角色
        Set<String> roles = new HashSet<String>();
        roles.add("role1");
        authorizationInfo.setRoles(roles);
        //权限
        Set<String> permissions = new HashSet<String>();
        permissions.add("user:list");
        //permissions.add("user:add");
        authorizationInfo.setStringPermissions(permissions);
        return authorizationInfo;
    }
 
    /**
     * 设置认证信息
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(
            AuthenticationToken authenticationToken) throws AuthenticationException {
        logger.info("开始认证(doGetAuthenticationInfo)");
        //UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken;
        HttpServletRequest request = (HttpServletRequest) ((WebSubject) SecurityUtils
                .getSubject()).getServletRequest();
        UsernamePasswordToken token = new UsernamePasswordToken (request.getParameter("userName"),request.getParameter("password"));
        //获取用户输入的账号
        String userName = (String)token.getPrincipal();
        //通过userName去数据库中匹配用户信息,通过查询用户的情况做下面的处理
        //这里暂时就直接写死,根据登录用户账号的情况做处理
        logger.info("账号:"+userName);
        if("passwordError".equals(userName)){//密码错误
            throw new IncorrectCredentialsException(); 
        }else if("lockAccount".equals(userName)){// 用户锁定
            throw new LockedAccountException(); 
        }else{
            SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(
                    userName, //用户名
                    "123456", //密码,写死
                    ByteSource.Util.bytes(userName+"salt"),//salt=username+salt
                    getName()  //realm name
            );
            return authenticationInfo;
        }
    }
    
}

第二步 实现Shiro的配置类:

package ariky.shiro.configuration;
 
import java.util.LinkedHashMap;
import java.util.Map;
 
import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 
import ariky.shiro.realm.MyShiroRealm;
 
/**
* @ClassName: ShiroConfiguration 
* @Description: shiro的配置类 
* @author fuweilian
* @date 2018-5-12 上午11:05:09
 */
@Configuration
public class ShiroConfiguration {
    private static Logger logger = LoggerFactory.getLogger(ShiroConfiguration.class);
    @Bean(name = "shiroFilter")
    public ShiroFilterFactoryBean shiroFilter(SecurityManager securityManager){
        logger.info("进入shiroFilter......");
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        //设置不需要拦截的路径
        Map<String,String> filterChainDefinitionMap = new LinkedHashMap<String, String>();
        //按顺序依次判断
        filterChainDefinitionMap.put("/static/**", "anon");
        //配置退出 过滤器,其中的具体的退出代码Shiro已经替我们实现了
        filterChainDefinitionMap.put("/logout", "logout");
        //<!-- authc:所有url都必须认证通过才可以访问; anon:所有url都都可以匿名访问-->
        /************************************初始化所有的权限信息开始******************************************/
        //这里,如果以后再项目中使用的话,直接从数据库中查询
        filterChainDefinitionMap.put("/user/list", "authc,perms[user:list]");
        //filterChainDefinitionMap.put("/user/add", "authc,perms[user:add]");
        /***************************************初始化所有的权限信息开始结束*********************************************/
        filterChainDefinitionMap.put("/**", "authc");
        // 如果不设置默认会自动寻找Web工程根目录下的"/login.jsp"页面
        shiroFilterFactoryBean.setLoginUrl("/login");
        // 登录成功后要跳转的链接
        shiroFilterFactoryBean.setSuccessUrl("/index");
        //未授权界面
        shiroFilterFactoryBean.setUnauthorizedUrl("/error/403");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
        return shiroFilterFactoryBean;
    }
    
    @Bean
    public MyShiroRealm myShiroRealm(){
         MyShiroRealm myShiroRealm = new MyShiroRealm();
         //后面这里可以设置缓存的机制
         return myShiroRealm;
    } 
    
    @Bean
    public SecurityManager securityManager(){
        DefaultWebSecurityManager securityManager =  new DefaultWebSecurityManager();
        securityManager.setRealm(myShiroRealm());
        return securityManager;
    }
    
    
    @Bean
    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {
        AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
        authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
        return authorizationAttributeSourceAdvisor;
    }
    
}

第三步:实现Controoler类,这里写俩个类,一个是登录信息的LoginController处理类,一个是测试权限用的UserController

1.LoginController.java

package ariky.controller;
 
import java.util.Map;
 
import javax.servlet.http.HttpServletRequest;
 
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.IncorrectCredentialsException;
import org.apache.shiro.authc.LockedAccountException;
import org.apache.shiro.authc.UnknownAccountException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
 
/**
* @ClassName: LoginController 
* @Description: 登录控制的controller
* @author fuweilian
* @date 2018-5-12 下午01:15:46
 */
@RequestMapping
@Controller
public class LoginController {
    private Logger logger = LoggerFactory.getLogger(LoginController.class);
    
    @RequestMapping(value="/login",method=RequestMethod.GET)
    public String getLogin(){
        logger.info("进入login页面");
        return "login";
    }
    
    @RequestMapping(value="/login",method=RequestMethod.POST)
    public String doLogin(HttpServletRequest req,Map<String, Object> model){
        logger.info("进入登录处理");
        String exceptionClassName = (String) req.getAttribute("shiroLoginFailure");
        logger.info("exceptionClassName:"+exceptionClassName);
        String error = null;
        if (UnknownAccountException.class.getName().equals(exceptionClassName)) {
            error = "用户名/密码错误";
        } else if (IncorrectCredentialsException.class.getName().equals(exceptionClassName)) {
            error = "用户名/密码错误";
        }else if(LockedAccountException.class.getName().equals(exceptionClassName)){ 
            error = "用户已锁定或已删除";
        }else if (exceptionClassName != null) {
            error = "其他错误:" + exceptionClassName;
        }
        if(SecurityUtils.getSubject().isAuthenticated()){//没有错误,但是已经登录了,就直接跳转到welcom页面
            model.put("name", req.getParameter("userName"));
            return "index";
        }else{//有错误的
            model.put("error", error);
            return "login";
        }
    }
    @RequestMapping("/index")
    public String index(){
        return "index";
    }
}

2.UserController.java

package ariky.controller;
 
import java.util.ArrayList;
import java.util.List;
 
import org.apache.shiro.authz.annotation.RequiresPermissions;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
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.ResponseBody;
 
/**
* @ClassName: UserController 
* @Description: 用户处理Controller
* @author fuweilian
* @date 2018-5-12 下午03:11:06
 */
@Controller
@RequestMapping("/user")
public class UserController {
    Logger logger = LoggerFactory.getLogger(UserController.class);
    @RequiresPermissions("user:list")//这个是配置是否有该权限的,如果是按上面的写法,这个是有权限的
    @RequestMapping(value="/list",method=RequestMethod.GET)
    public String getList(){
        logger.info("进入用户列表");
        return "user/list";
    }
    @RequiresPermissions(value={"user:add"})//这个是没有权限的
    @RequestMapping(value="/add",method=RequestMethod.GET)
    public String getAdd(){
        logger.info("进入新增用户界面");
        return "user/add";
    }
    
}

前端界面:有5个界面 (login.jsp,index.jsp,list.jsp,add.jsp,403.jsp)

目录结构为:

1.login.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Login</title>
</head>
 
<body>
    <h1>登录页面----${error}</h1>
    <form:form action="${pageContext.request.contextPath }/login"
         method="post">
        用户名:<input type="text" name="userName">
        <br />
        密码:<input type="passwordParam" name="password"/>
        <input type="submit" value="提交"/>
    </form:form>
</body>
</html>

2.index.jsp

<%@ page language="java" pageEncoding="UTF-8"%>
 <%@taglib prefix="shiro" uri="http://shiro.apache.org/tags" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>第一个例子</title>
<script src="${pageContext.request.contextPath }/webjars/jquery/2.1.4/jquery.js"></script>
<script src="${pageContext.request.contextPath }/webjarslocator/jquery/jquery.js"></script>
</head>
 
<body>
    <h1>${name}:你好,欢迎访问该网页</h1>
        <shiro:hasPermission name="user:list"><!-- 这个a标签是可以看见的 -->
            <a href="${pageContext.request.contextPath }/user/list" target="_blank">跳转到用户列表(有权限)</a>
        </shiro:hasPermission>
    <br/>
        <shiro:hasPermission name="user:add"><!-- 这个a标签是看不见的 -->
            <a href="${pageContext.request.contextPath }/user/add" target="_blank">跳转到新增用户列表(无权限)</a>
        </shiro:hasPermission>
</body>
</html>

3.list.jsp和add.jsp以及403.jsp都差不多一样,这里就写一个,这里只是demo所用,在实际项目中,要以实际项目为准

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>userList</title>
</head>
 
<body>
    <h1>用户列表信息</h1>
</body>
</html>

上面就是全部代码了,如果启动成功,进入login登录界面就可以测试一下shiro的权限认证了。上面的代码都是写死的,如果想要实现动态的权限管理和用户的权限管理的话,还要做一些其他处理,用户的动态权限这个只要在自己的ShiroRealm类里面授权的时候做一下查询数据库,动态的授权和角色就行。关于动态的权限管理的话,下面的方式可以实现,在修改完权限数据后,更新一下shiro里面的配置就行,具体看下面的代码,这里是demo,不是实际项目,在实际项目中最好不要把逻辑写在Controller里面

package ariky.shiro.controller;
 
import java.util.LinkedHashMap;

@RequestMapping("permssion")
public class PermssionController {
    
     @Autowired
     ShiroFilterFactoryBean shiroFilterFactoryBean;
     
     /**

      */
    @RequestMapping("/updatePermssion")
    @ResponseBody
    public Object updatePermssion(){
        synchronized (shiroFilterFactoryBean){
            AbstractShiroFilter shiroFilter = null;
            try {
                shiroFilter = (AbstractShiroFilter) shiroFilterFactoryBean
                        .getObject();
                PathMatchingFilterChainResolver filterChainResolver = (PathMatchingFilterChainResolver) shiroFilter
                    .getFilterChainResolver();
                DefaultFilterChainManager manager = (DefaultFilterChainManager) filterChainResolver
                    .getFilterChainManager();
                // 清空老的权限控制
                manager.getFilterChains().clear();
                shiroFilterFactoryBean.getFilterChainDefinitionMap().clear();
                //后面这个可以直接从数据库里面获取
                Map<String,String> filterChainDefinitionMap = new LinkedHashMap<String, String>();

                /***************************************初始化所有的权限信息开始结束*********************************************/
                filterChainDefinitionMap.put("/**", "authc");

                //未授权界面
                shiroFilterFactoryBean.setUnauthorizedUrl("/error/403");
                shiroFilterFactoryBean
                    .setFilterChainDefinitionMap(filterChainDefinitionMap);
                // 重新构建生成
                Map<String, String> chains = shiroFilterFactoryBean
                        .getFilterChainDefinitionMap();
                for (Map.Entry<String, String> entry : chains.entrySet()) {
                    String url = entry.getKey();
                    String chainDefinition = entry.getValue().trim()
                            .replace(" ", "");

            } catch (Exception e) {
                throw new RuntimeException(
                        "更新shiro权限出现错误!");
            }
        }
