spring整合shiro权限管理与数据库设计

其他 2018-08-27 11:01:26 阅读次数: 0

之前的文章中我们完成了基础框架的搭建，现在基本上所有的后台系统都逃不过权限管理这一块，这算是一个刚需了。现在我们来集成shiro来达到颗粒化权限管理，也就是从连接菜单到页面功能按钮，都进行权限都验证，从前端按钮的显示隐藏，到后台具体功能方法的权限验证。

首先要先设计好我们的数据库，先来看一张比较粗糙的数据库设计图：


具体的数据库设计代码，请查看：https://git.oschina.net/gzsjd/task/blob/master/sql/task.sql?dir=0&filepath=sql

下面我们开始根据之前的框架集成shiro

首先在pom.xml添加shiro的支持，先在properties中声明一下要倒入的版本：

<properties>
	<shiro.version>1.3.2</shiro.version>
	<commons-logging.version>1.2</commons-logging.version>
</properties>
然后在是dependency的添加： 

<!-- shiro权限 -->
		<dependency>
			<groupId>org.apache.shiro</groupId>
			<artifactId>shiro-all</artifactId>
			<version>${shiro.version}</version>
		</dependency>
		
		<!-- commons-logging -->
		<dependency>
		    <groupId>commons-logging</groupId>
		    <artifactId>commons-logging</artifactId>
		    <version>${commons-logging.version}</version>
		</dependency>
下面是shiro的配置跟spring配置放在同级目录spring-shiro.xml： 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:util="http://www.springframework.org/schema/util"
       xmlns:aop="http://www.springframework.org/schema/aop"

上面的

/static/** = anon，/login.jsp = anon...这些等于anon的就是默认不做权限验证的，我们的登录，注册，静态资源等，不需要权限验证。

权限缓存的配置（如果不用缓存的话，每次请求都要去访问数据库查询权限）ehcache-shiro.xml： 

<?xml version="1.0" encoding="UTF-8"?>
<ehcache name="shirocache">

    <diskStore path="java.io.tmpdir/yfkj-shiro-ehcache"/>
	
	<!-- 默认缓存 -->
	<defaultCache maxElementsInMemory="1000" eternal="false"
		overflowToDisk="true" timeToIdleSeconds="300" timeToLiveSeconds="180"
		diskPersistent="false" diskExpiryThreadIntervalSeconds="120" />
	
    <!-- 登录记录缓存 -->
    <cache name="passwordRetryCache"
           maxEntriesLocalHeap="2000"
           eternal="false"
           timeToIdleSeconds="3600"
           timeToLiveSeconds="0"
           overflowToDisk="false"
           statistics="true">
    </cache>

	<!-- 授权缓存 -->
    <cache name="authorizationCache"
           maxEntriesLocalHeap="2000"
           eternal="false"
           timeToIdleSeconds="3600"
           timeToLiveSeconds="0"
           overflowToDisk="false"
           statistics="true">
    </cache>

	<!-- 认证缓存 -->
    <cache name="authenticationCache"
           maxEntriesLocalHeap="2000"
           eternal="false"
           timeToIdleSeconds="3600"
           timeToLiveSeconds="0"
           overflowToDisk="false"
           statistics="true">
    </cache>

    <cache name="shiro-activeSessionCache"
           maxEntriesLocalHeap="2000"
           eternal="false"
           timeToIdleSeconds="3600"
           timeToLiveSeconds="0"
           overflowToDisk="false"
           statistics="true">
    </cache>
    
    <cache name="shiro-kickout-session"
           maxEntriesLocalHeap="2000"
           eternal="false"
           timeToIdleSeconds="3600"
           timeToLiveSeconds="0"
           overflowToDisk="false"
           statistics="true">
    </cache>

</ehcache>
自定义用户过滤类SysUserFilter： 

import yfkj.gz.task.service.ISysUserService;

import org.apache.shiro.web.filter.PathMatchingFilter;

import javax.annotation.Resource;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

/**
 * 自定义用户过滤器
 * @author 胡汉三
 *
 */
public class SysUserFilter extends PathMatchingFilter {
	
	@Resource
	private ISysUserService sysUserService;

    @Override
    protected boolean onPreHandle(ServletRequest request, ServletResponse response, Object mappedValue) throws Exception {
        //可以参考http://jinnianshilongnian.iteye.com/blog/2025656
    	return true;
    }
}
权限认证类ShiroSecurityRealm： 

import javax.annotation.Resource;

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.authc.UsernamePasswordToken;
import org.apache.shiro.authc.credential.Sha256CredentialsMatcher;
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.springframework.stereotype.Component;

import yfkj.gz.task.dao.ISysUserDao;
import yfkj.gz.task.entity.SysRole;
import yfkj.gz.task.entity.SysUser;
import yfkj.gz.task.service.ISysUserService;

/**
 * 权限认证
 * @author 胡汉三
 * @date   2017年1月19日 上午10:52:17
 */
@SuppressWarnings("deprecation")
@Component
public class ShiroSecurityRealm extends AuthorizingRealm {
	
	@Resource
    private ISysUserService userService;

	@Resource
	private ISysUserDao sysUserDao;

	public ShiroSecurityRealm() {
		setName("ShiroSecurityRealm"); // This name must match the name in the SysUser class's getPrincipals() method
		setCredentialsMatcher(new Sha256CredentialsMatcher());
	}

	/**
	 * 登录认证
	 */
	protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authcToken) throws AuthenticationException {
		UsernamePasswordToken token = (UsernamePasswordToken) authcToken;
		SysUser user = userService.getByProerties(new String[]{"loginAccount"}, new String[]{token.getUsername()},null);
		if (user != null) {
			return new SimpleAuthenticationInfo(user.getUserId(), user.getLoginPass(), getName());
		} else {
			return null;
		}
	}


	/**
	 * 权限认证
	 */
	protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
		Long userId = (Long) principals.fromRealm(getName()).iterator().next();
		SysUser user = userService.get(userId);
		if (user != null) {
			SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
			for (SysRole role : user.getRoles()) {
				info.addRole(role.getRoleKey());
				info.addStringPermissions(role.getPermissions());
			}
			return info;
		} else {
			return null;
		}
	}

}
在web.xml加入： 

<!-- 加载spring配置文件 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring.xml,classpath:spring-hibernate.xml,classpath:spring-shiro.xml</param-value>
	</context-param>
	
	<!-- shiro权限过滤器 -->
	<filter>
		<filter-name>shiroFilter</filter-name>
		<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
		<init-param>
			<param-name>targetFilterLifecycle</param-name>
			<param-value>true</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>shiroFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
在登录方法中加上权限的登录(构造方法参数：登录账号，登录密码，记住我)： 

//存入session
		Subject subject = SecurityUtils.getSubject();
		//记得传入明文密码
		subject.login(new UsernamePasswordToken(userInfo.getLoginAccount(), user.getLoginPass(), rememberMe));
完整的登录方法： 

/**
	 * 用户登录
	 * @param response
	 * @param user
	 * @throws IOException
	 */
	@RequestMapping(value = "/login", method = { RequestMethod.POST, RequestMethod.GET })
	public void login(SysUser user,boolean rememberMe) throws IOException{
		//用户登录
		SysUser userInfo = userService.getByProerties(new String[]{"loginAccount"}, new String[]{user.getLoginAccount()},null);
		if(userInfo==null){
			result.setMessage("用户名错误");
			super.writeJSON(result);
			return;
		}
		if(!userInfo.getLoginPass().equals(new Sha256Hash(user.getLoginPass()).toHex())){
			result.setMessage("密码错误");
			super.writeJSON(result);
			return;
		}
		//存入session
		Subject subject = SecurityUtils.getSubject();
		//记得传入明文密码
		subject.login(new UsernamePasswordToken(userInfo.getLoginAccount(), user.getLoginPass(), rememberMe));
		session.setAttribute(USER_SESSION, userInfo);
		result.setMessage("登录成功");
		result.setSuccess(true);
		super.writeJSON(result);
	}
数据库也设计好啦，该整合的也整合了，怎么来实现呢，这里先说一点点，详细的等下一篇说：

jsp页面引入page指令：

<%@ taglib prefix="shiro" uri="http://shiro.apache.org/tags" %>
在要做验证的按钮上加上shiro标签的判断： 

<shiro:hasPermission name="${ROLE_KEY}:role:role_add">
					<button id="btn_add" type="button" class="btn btn-default">
						<span class="glyphicon glyphicon-plus" aria-hidden="true"></span>新增
					</button>
					</shiro:hasPermission>
${ROLE_KEY}:role:role_add的意思就是：

${ROLE_KEY}角色

role是指菜单(页面)

role_add指的功能

联合起来就是，当前角色在role菜单(页面)中有没有role_add新增的功能，如果有就会显示，没有就不显示这个按钮啦。

在后台方法中验证：

在对应的方法中加入代码：

Subject subject = SecurityUtils.getSubject();
subject.checkPermission(getCurrentRoleKey()+":role:role_add");
如果没有通过checkPermission，则会直接返回错误，不执行下面的代码啦。


实体Base类BaseEntity：

/**
