Spring整合Shiro做权限控制模块详细案例分析
1.引入Shiro的Maven依赖
<!-- Spring 整合Shiro需要的依赖 -->
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-core</artifactId>
<version>1.2.1</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-web</artifactId>
<version>1.2.1</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-ehcache</artifactId>
<version>1.2.1</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.2.1</version>
</dependency>
<!-- 除此之外还有一些东西也不可少spring, spring-mvc, ibatis等 spring.3.1.2 spring-mvc.3.1.2
ibatis.2.3.4 cglib.2.2 -->
2.web.xml中配置
<!-- 配置shiro的核心拦截器 -->
<filter>
<filter-name>shiroFilter</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
3. 编写自己的UserRealm类继承自Realm，主要实现认证和授权的管理操作
package com.jay.demo.shiro;import java.util.HashSet;import java.util.Iterator;import java.util.Set;import org.apache.shiro.authc.AuthenticationException;import org.apache.shiro.authc.AuthenticationInfo;import org.apache.shiro.authc.AuthenticationToken;import org.apache.shiro.authc.LockedAccountException;import org.apache.shiro.authc.SimpleAuthenticationInfo;import org.apache.shiro.authc.UnknownAccountException;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.beans.factory.annotation.Autowired;import com.jay.demo.bean.Permission;import com.jay.demo.bean.Role;import com.jay.demo.bean.User;import com.jay.demo.service.UserService;
public class UserRealm extends AuthorizingRealm{
@Autowired
private UserService userService; /**
* 授权操作
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {// String username = (String) getAvailablePrincipal(principals);
String username = (String) principals.getPrimaryPrincipal();
Set<Role> roleSet = userService.findUserByUsername(username).getRoleSet(); //角色名的集合
Set<String> roles = new HashSet<String>(); //权限名的集合
Set<String> permissions = new HashSet<String>();
Iterator<Role> it = roleSet.iterator(); while(it.hasNext()){
roles.add(it.next().getName()); for(Permission per:it.next().getPermissionSet()){
permissions.add(per.getName());
}
}
SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
authorizationInfo.addRoles(roles);
authorizationInfo.addStringPermissions(permissions);
return authorizationInfo;
} /**
* 身份验证操作
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo( AuthenticationToken token) throws AuthenticationException {
String username = (String) token.getPrincipal(); User user = userService.findUserByUsername(username);
if(user==null){ //木有找到用户
throw new UnknownAccountException("没有找到该账号");
} /* if(Boolean.TRUE.equals(user.getLocked())) {
throw new LockedAccountException(); //帐号锁定
} */
/**
* 交给AuthenticatingRealm使用CredentialsMatcher进行密码匹配，如果觉得人家的不好可以在此判断或自定义实现
*/
SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(),getName());
return info;
}
@Override
public String getName() { return getClass().getName();
}
}
4.在Spring的applicationContext.xml中进行Shiro的相关配置
1、添加shiroFilter定义
Xml代码
-
<!-- Shiro Filter -->
-
< bean id = "shiroFilter" class = "org.apache.shiro.spring.web.ShiroFilterFactoryBean" >
-
< property name = "securityManager" ref = "securityManager" />
-
< property name = "loginUrl" value = "/login" />
-
< property name = "successUrl" value = "/user/list" />
-
< property name = "unauthorizedUrl" value = "/login" />
-
< property name = "filterChainDefinitions" >
-
< value >
-
/ login = anon
-
/user/** = authc
-
/role/edit/* = perms[role:edit]
-
/role/ save = perms [role:edit]
-
/role/ list = perms [role:view]
-
/** = authc
-
</ value >
-
</ property >
-
</ bean >
2、添加securityManager定义
Xml代码
-
< bean id = "securityManager" class = "org.apache.shiro.web.mgt.DefaultWebSecurityManager" >
-
< property name = "realm" ref = "myRealm" />
-
</ bean >
3、添加realm定义
Xml代码
-
< bean id = " myRealm" class = "com.jay.demo.shiro.
UserRealm<span class="attribute-value" style="font-size: 1em; font-family: Monaco, 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', Consolas, 'Courier New', monospace; background-color: rgb(250, 250, 250);">"</span><span style="color: black; font-size: 1em; font-family: Monaco, 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', Consolas, 'Courier New', monospace; background-color: rgb(250, 250, 250);"> </span><span class="tag" style="font-size: 1em; font-family: Monaco, 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', Consolas, 'Courier New', monospace; color: rgb(0, 102, 153); font-weight: bold; background-color: rgb(250, 250, 250);">/></span><span style="color: black; font-size: 1em; font-family: Monaco, 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', Consolas, 'Courier New', monospace; background-color: rgb(250, 250, 250);"> </span>
4、配置EhCache
< bean id = "cacheManager" class = "org.apache.shiro.cache.ehcache.EhCacheManager" />
5、 保证实现了Shiro内部lifecycle函数的bean执行
<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>
特别注意：
如果使用Shiro相关的注解，需要在springmvc-servlet.xml中配置一下信息
<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor"/><bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
<property name="securityManager" ref="securityManager"/></bean>
备注：Shiro权限管理的过滤器解释：
默认过滤器(10个)
anon -- org.apache.shiro.web.filter.authc.AnonymousFilterauthc -- org.apache.shiro.web.filter.authc.FormAuthenticationFilterauthcBasic -- org.apache.shiro.web.filter.authc.BasicHttpAuthenticationFilterperms -- org.apache.shiro.web.filter.authz.PermissionsAuthorizationFilterport -- org.apache.shiro.web.filter.authz.PortFilterrest -- org.apache.shiro.web.filter.authz.HttpMethodPermissionFilterroles -- org.apache.shiro.web.filter.authz.RolesAuthorizationFilterssl -- org.apache.shiro.web.filter.authz.SslFilteruser -- org.apache.shiro.web.filter.authc.UserFilterlogout -- org.apache.shiro.web.filter.authc.LogoutFilteranon:例子/admins/**=anon 没有参数，表示可以匿名使用。
authc:例如/admins/user/**=authc表示需要认证(登录)才能使用，没有参数 roles：例子/admins/user/**=roles[admin],参数可以写多个，多个时必须加上引号，并且参数之间用逗号分割，当有多个参数时，例如admins/user/**=roles["admin,guest"],每个参数通过才算通过，相当于hasAllRoles()方法。 perms：例子/admins/user/**=perms[user:add:*],参数可以写多个，多个时必须加上引号，并且参数之间用逗号分割，例如/admins/user/**=perms["user:add:*,user:modify:*"]，当有多个参数时必须每个参数都通过才通过，想当于isPermitedAll()方法。 rest：例子/admins/user/**=rest[user],根据请求的方法，相当于/admins/user/**=perms[user:method] ,其中method为post，get，delete等。 port：例子/admins/user/**=port[8081],当请求的url的端口不是8081是跳转到schemal://serverName:8081?queryString,其中schmal是协议http或https等，serverName是你访问的host,8081是url配置里port的端口，queryString是你访问的url里的？后面的参数。 authcBasic：例如/admins/user/**=authcBasic没有参数表示httpBasic认证 ssl:例子/admins/user/**=ssl没有参数，表示安全的url请求，协议为https user:例如/admins/user/**=user没有参数表示必须存在用户，当登入操作时不做检查
