基于spring框架的apache shiro简单集成

    添加时间:2013-7-11 点击量:

    关于项目标安然保护,我一向想找一个简单设备就能达到目标的办法,自从接触了shiro,这个目标总算杀青了,以下连络我应用shiro的经验,谈谈斗劲简便地集成该功能。


    起首我们先懂得一下shiro是什么。


    apache shiro 是一个功能强大易于应用Java安然框架,为开辟人员供给一个直观而周全的解决规划认证,授权加密会话经管


    其实遵守我小我的懂得,就是个过滤器,遵守设备(或者注解)的规矩进行权限验证。


    我的项目基于maven经管依附jar包,起首把apache shiro相干须要用到的jar引入:



    <!-- shiro -->
    
    <dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-web</artifactId>
    <version>1.2.1</version>
    </dependency>
    <dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring</artifactId>
    <version>1.2.1</version>
    </dependency>

    <dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-ehcache</artifactId>
    <version>1.2.1</version>
    </dependency>


    此中shiro-web和shiro-spring必须,若是要缓存权限的话,就引入shiro-ehcache,后边会具体说道shiro-ehcache的应用。


    看一下login.action里是如何实现用户登录写入的,获取用户表单信息以及查询数据库验证就不说了,直接上关键代码:



    
    
    //验证用户信息掉队行token写入,这里为了简单,我把用户的id和姓名作为token的username和password

    UsernamePasswordToken token
    = new UsernamePasswordToken(m.getId()
    .toString(), m.getUsername());
    Subject subject1
    = SecurityUtils.getSubject();
    subject1.login(token);
    subject1.getSession();



    既然是个过滤器,那我们就看一下这个过滤器的写法:



    package com.airfey.tech.nuo.action.shiro.filter;
    

    import java.io.IOException;
    import java.security.Principal;

    import javax.annotation.Resource;
    import javax.servlet.Filter;
    import javax.servlet.FilterChain;
    import javax.servlet.FilterConfig;
    import javax.servlet.ServletException;
    import javax.servlet.ServletRequest;
    import javax.servlet.ServletResponse;
    import javax.servlet.http.Cookie;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;

    import org.apache.shiro.SecurityUtils;
    import org.apache.shiro.authc.UsernamePasswordToken;
    import org.apache.shiro.subject.Subject;

    import com.airfey.tech.nuo.common.security.MD5;
    import com.airfey.tech.nuo.core.domain.Manager;
    import com.airfey.tech.nuo.core.service.ManagerService;

    public class shiroFilter implements Filter {
    //经管员用户service
    @Resource
    private ManagerService managerService;

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {

    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response,
    FilterChain chain)
    throws IOException, ServletException {

    Subject subjects
    = SecurityUtils.getSubject();

    HttpServletRequest requestHttp
    = (HttpServletRequest) request;
    HttpServletResponse responseHttp
    = (HttpServletResponse) response;

    Principal principal
    = requestHttp.getUserPrincipal();
    ifnull != principal) {
    //principal.getName()里保存的是用户的id,就是上边登录处token里的信息
    System.out.println(principal.getName());
    Manager m
    = managerService.findOne(Long.parseLong(principal
    .getName()));
    ifnull != m && 1 == m.getAudit()) {
    UsernamePasswordToken token
    = new UsernamePasswordToken(
    m.getId(), m.getId());//作为例子,这里我只是把用户id放进了token,你可以批改成其它错杂点的信息
    Subject subject1
    = SecurityUtils.getSubject();
    subject1.login(token);
    subject1.getSession();
    }
    else {
    if (subjects != null) {
    subjects.logout();
    }
    }
    }


    chain.doFilter(requestHttp, responseHttp);

    }

    @Override
    public void destroy() {

    }

    }


    至此,可以说登录和过滤器已经完成了。然后就进行web.xml和spring文件以及权限验证的实现。


    1、在web.xml里参加shiro的过滤器设备:



    <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>


    此过滤器要位于所有过滤器的前面。


     2、权限验证代码实现,我们写一个realm类集成shiro的AuthorizingRealm



    package com.airfey.tech.nuo.action.shiro.realm;
    

    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.authz.AuthorizationException;
    import org.apache.shiro.authz.AuthorizationInfo;
    import org.apache.shiro.authz.SimpleAuthorizationInfo;
    import org.apache.shiro.cache.Cache;
    import org.apache.shiro.realm.AuthorizingRealm;
    import org.apache.shiro.subject.PrincipalCollection;
    import org.apache.shiro.subject.SimplePrincipalCollection;

    public class ShiroRealm extends AuthorizingRealm {

    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(
    PrincipalCollection principals) {
    if (principals == null) {
    throw new AuthorizationException(
    PrincipalCollection method argument cannot be null.);
    }
    String username
    = (String) getAvailablePrincipal(principals);
    System.out.println(------------------- + username);//输出的其实是用户id

    SimpleAuthorizationInfo info
    = new SimpleAuthorizationInfo();
    // 增长默认角色
    info.addRole(ROLE_USER);
    /以下可以从数据库获取用户的角色以及权限信息,获取到的信息添参加info即可,具体获取数据库的代码我就省略了/
    // // 增长自定义角色
    // if (null != userInfo.getRoleList()) {
    // for (RoleInfo roleInfo : userInfo.getRoleList()) {
    // if (null != roleInfo.getName()
    // && !.equals(roleInfo.getName())) {
    // info.addRole(roleInfo.getName());
    // }
    // }
    // }
    // if (null != userInfo.getModuleInfo()) {
    // for (ModuleInfo moduleInfo : userInfo.getModuleInfo()) {
    // if (null != moduleInfo.getGuid()
    // && !.equals(moduleInfo.getGuid())) {
    // info.addStringPermission(moduleInfo.getGuid());
    // }
    // }
    // }

    return info;

    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(
    AuthenticationToken authcToken)
    throws AuthenticationException {
    UsernamePasswordToken token
    = (UsernamePasswordToken) authcToken;
    String userName
    = token.getUsername();
    if (userName != null && !.equals(userName)) {

    return new SimpleAuthenticationInfo(token.getPrincipal(),
    token.getPassword(), token.getUsername());
    }
    return null;
    }

    /
    清空用户接洽关系权限认证,待下次应用时从头加载。

    @param principal
    /
    public void clearCachedAuthorizationInfo(String principal) {
    SimplePrincipalCollection principals
    = new SimplePrincipalCollection(
    principal, getName());
    clearCachedAuthorizationInfo(principals);
    }

    /
    清空所有接洽关系认证
    /
    public void clearAllCachedAuthorizationInfo() {
    Cache
    <Object, AuthorizationInfo> cache = getAuthorizationCache();
    if (cache != null) {
    for (Object key : cache.keys()) {
    cache.remove(key);
    }
    }
    }
    }


    3、applicationContext.xml的设备 (这里只保存了shiro相干的信息)



    <?xml version=1.0 encoding=UTF-8?>
    
    <beans xmlns=http://www.springframework.org/schema/beans
    xmlns:aop
    =http://www.springframework.org/schema/aop xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance
    xmlns:context
    =http://www.springframework.org/schema/context xmlns:tx=http://www.springframework.org/schema/tx
    xsi:schemaLocation
    =http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.0.xsd>

    <bean id=shiroFilter class=org.apache.shiro.spring.web.ShiroFilterFactoryBean>
    <property name=securityManager ref=securityManager />
    <property name=successUrl value=/manage/index.do />
    <property name=loginUrl value=/manage/login.do />
    <property name=unauthorizedUrl value=/manage/401.html />
    <property name=filters>
    <map>
    <entry key=authc value-ref=shiro></entry>
    </map>
    </property>
    <property name=filterChainDefinitions>
    <value>
    /manage/admin.html = authc,perms[shiro_admin:view]
    /manage/user.html=authc,perms[shiro_user:view]

    /manage/login.do=anon
    /manage/401.html=anon
    /manage/js/=anon
    /manage/img/=anon
    /manage/kindeditor/=anon
    /manage/=authc,roles[ROLE_USER]
    /=anon
    </value>
    </property>
    </bean>
    <bean id=shiro class=com.airfey.tech.nuo.action.shiro.filter.shiroFilter>

    </bean>
    <bean id=shiroRealm class=com.airfey.tech.nuo.action.shiro.realm.ShiroRealm />
    <bean id=securityManager class=org.apache.shiro.web.mgt.DefaultWebSecurityManager>
    <property name=realm ref=shiroRealm />
    <property name=cacheManager ref=shiroEhcacheManager />
    </bean>

    <!-- 用户授权信息Cache, 采取EhCache,须要的话就设备上此信息 -->
    <bean id=shiroEhcacheManager class=org.apache.shiro.cache.ehcache.EhCacheManager>
    <property name=cacheManagerConfigFile value=classpath:ehcache-shiro.xml />
    </bean>

    <bean id=lifecycleBeanPostProcessor class=org.apache.shiro.spring.LifecycleBeanPostProcessor />
    <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>


    </beans>


    验证规矩里如下让静态文件比如js img 目次设备上anon


    /manage/admin.html = authc,perms[shiro_admin:view]


    /manage/user.html=authc,perms[shiro_user:view]


    /manage/login.do=anon


    /manage/401.html=anon


    /manage/js/=anon


    /manage/img/=anon


    /manage/kindeditor/=anon


    /manage/=authc,roles[ROLE_USER]


    /=anon
