shiro是一款java安全框架、简单而且可以满足实际的工作需要
第一步、导入maven依赖
<!-- shiro -->
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-core</artifactId>
<version>${org.apache.shiro.version}</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-web</artifactId>
<version>${org.apache.shiro.version}</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>${org.apache.shiro.version}</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-ehcache</artifactId>
<version>${org.apache.shiro.version}</version>
</dependency>
第二步、在项目中定义shiro的过滤器（shiro的实现主要是通过filter实现）
<!-- Shiro Security filter -->
<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>
<dispatcher>REQUEST</dispatcher>
</filter-mapping>
第三步、创建一个Realm
public class UserRealm extends AuthorizingRealm {
@Autowired
private UserBiz biz;
//验证用户信息，认证的实现
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
String userno = (String) authenticationToken.getPrincipal();
String password = new String((char[]) authenticationToken.getCredentials());
Result<RcUser> result = biz.login(userno, password);
if (result.isStatus()) {
Session session = SecurityUtils.getSubject().getSession();
session.setAttribute(Constants.Token.RONCOO, userno);
RcUser user = result.getResultData();
return new SimpleAuthenticationInfo(user.getUserNo(), user.getPassword(), getName());
}
return null;
}
//验证用户的权限，实现认证
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
String userno = (String) principals.getPrimaryPrincipal();
Result<RcUser> result = biz.queryByUserNo(userno);
if(result.isStatus()){
Result<List<RcRole>> resultRole = biz.queryRoles(result.getResultData().getId());
if(resultRole.isStatus()){
//获取角色
HashSet<String> roles = new HashSet<String>();
for (RcRole rcRole : resultRole.getResultData()) {
roles.add(rcRole.getRoleValue());
}
System.out.println("角色："+roles);
authorizationInfo.setRoles(roles);
//获取权限
Result<List<RcPermission>> resultPermission = biz.queryPermissions(resultRole.getResultData());
if(resultPermission.isStatus()){
HashSet<String> permissions = new HashSet<String>();
for (RcPermission rcPermission : resultPermission.getResultData()) {
permissions.add(rcPermission.getPermissionsValue());
}
System.out.println("权限："+permissions);
authorizationInfo.setStringPermissions(permissions);
}
}
}
return authorizationInfo;
}
}
第四步、添加shiro配置
1、shiro缓存
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>
<ehcache updateCheck="false" name="shiroCache">
<!-- http://ehcache.org/ehcache.xml -->
<defaultCache
maxElementsInMemory="10000"
eternal="false"
timeToIdleSeconds="120"
timeToLiveSeconds="120"
overflowToDisk="false"
diskPersistent="false"
diskExpiryThreadIntervalSeconds="120"
/>
</ehcache>
2、在spring的core配置文件中配置shiro
<description>Shiro安全配置</description>
<bean id="userRealm" class="com.roncoo.adminlte.controller.realm.UserRealm" />
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="realm" ref="userRealm" />
<property name="cacheManager" ref="shiroEhcacheManager" />
</bean>
<!-- Shiro 过滤器 -->
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
<!-- Shiro的核心安全接口,这个属性是必须的 -->
<property name="securityManager" ref="securityManager" />
<!-- 身份认证失败，则跳转到登录页面的配置 -->
<property name="loginUrl" value="/login" />
<property name="successUrl" value="/certification" />
<property name="unauthorizedUrl" value="/error" />
<!-- Shiro连接约束配置,即过滤链的定义 -->
<property name="filterChainDefinitions">
<value>
/login = authc
/exit = anon
/admin/security/list=authcBasic,perms[admin:read]
/admin/security/save=authcBasic,perms[admin:insert]
/admin/security/update=authcBasic,perms[admin:update]
/admin/security/delete=authcBasic,perms[admin:delete]
</value>
</property>
</bean>
<!-- 用户授权信息Cache, 采用EhCache -->
<bean id="shiroEhcacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager">
<property name="cacheManagerConfigFile" value="classpath:ehcache/ehcache-shiro.xml" />
</bean>
<!-- 保证实现了Shiro内部lifecycle函数的bean执行 -->
<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor" />
<!-- AOP式方法级权限检查 -->
<bean
class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"
depends-on="lifecycleBeanPostProcessor">
<property name="proxyTargetClass" value="true" />
</bean>
<bean
class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
<property name="securityManager" ref="securityManager" />
</bean>
第五步、shiro退出登录的实现
第一种方式
/**
* 退出登陆操作
*/
@RequestMapping(value = "/exit", method = RequestMethod.GET)
public String exit(RedirectAttributes redirectAttributes, HttpSession session) {
session.removeAttribute(Constants.Token.RONCOO);
SecurityUtils.getSubject().logout();
redirectAttributes.addFlashAttribute("msg", "您已经安全退出");
return redirect("/login");
}
第二种方式：在shiroFilter的约束配置中配置
<!-- Shiro连接约束配置,即过滤链的定义 -->
<property name="filterChainDefinitions">
<value>
/exit = logout
</value>
</property>
