Apache Shiro是java的一个安全框架。目前,使用Apache Shiro的人越来越多,因为它相当简单,对比SPRing Security,可能没有Spring Security做的功能强大,但是在实际工作时可能并不需要那么复杂的东西,所以使用小而简单的Shiro就足够了。
因为我总结的是使用SpringMVC和Apache Shiro整合,注重的是整合和使用,至于基础,我这里就不细说了.按照惯例,既然是需要创建项目,那么我们首先需要JAR包,Apache shiro的架包除了除了基本的以外,我们还需要shiro-web和shiro-spring的的架包,下面是所需要的所有shiro架包,至于其他的架包,像缓存的架包,Spring和SpringMVC的架包还是和我们以前使用的架包一样的。
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-core</artifactId>
<version>1.2.3</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-ehcache</artifactId>
<version>1.2.3</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-web</artifactId>
<version>1.2.3</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.2.3</version>
</dependency>
所有的架包都搞清楚了以后,我们就可以开始正式搭建了,在myeclise中创建一个maven项目,将需要的架包信息依赖全部放入。下面就分步骤来创建
1.首先创建spring的配置文件,位置都在在resource中,配置文件是spring-context.xml,创建Apache Shiro的配置文件,名字是spring-context-shiro.xml,还有一个配置文件是springmvc的,配置文件是spring-mvc,这样起名是有原因的,因为这样我们就可以在web.xml中设置配置文件的时候,直接使用通配符了:
<!--配置spring容器的路径--><context-param><param-name>contextConfigLocation</param-name><param-value>classpath*:/spring-context-*.xml</param-value></context-param><!--对spring开始监听--><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener>
这样就可以扫描到两个配置文件了,又不会扫描到我们的spring-mvc.xml了,
2除了在web.xml中设置这个以外,我们还需要设置spring-mvc的位置:
<!--MVC Servlet
设置springmvc的Servlet--><servlet><servlet-name>springServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springmvc.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>springServlet</servlet-name><url-pattern>/</url-pattern></servlet-mapping>
3.在web.xml中配置shiroFilter:
<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>
注意,这个shiroFilter名称,后面的配置还需要使用到,所以要注意咯。
4,因为shiro的session是自己实现的,所以我们还需要一个缓存框架,所以在spring的配置文件一定要注意配置哦,
<!--缓存--><beanid="cacheManager"class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"><propertyname="configLocation"value="classpath:${ehcache.file}"></property></bean>
spring的其他的配置,该怎样还是这样,我们的重点是配置spring-context-shiro.xml:先把配置的贴出来,然后讲一下这几个配置的意义:

ecurityManager:是shiro最重要的一个对象,授权和验证都是由它来做的,下面就一一的来讲他的依赖类,
一:realm:域,Shiro从从Realm获取安全数据(如用户、角色、权限),就是说SecurityManager要验证用户身份,那么它需要从Realm获取相应的用户进行比较以确定用户身份是否合法;也需要从Realm得到用户相应的角色/权限进行验证用户是否能进行操作;可以把Realm看成DataSource,即安全数据源。下对于源代码,我就不细细的研究了,下面是我重写的realm,:
packagecom.yonyou.hotusm.module.sys.security;importjava.io.Serializable;importorg.apache.shiro.authc.AuthenticationException;importorg.apache.shiro.authc.AuthenticationInfo;importorg.apache.shiro.authc.AuthenticationToken;importorg.apache.shiro.authc.SimpleAuthenticationInfo;importorg.apache.shiro.authc.UsernamePassWordToken;importorg.apache.shiro.authz.AuthorizationInfo;importorg.apache.shiro.authz.SimpleAuthorizationInfo;importorg.apache.shiro.authz.UnauthenticatedException;importorg.apache.shiro.realm.AuthorizingRealm;importorg.apache.shiro.subject.PrincipalCollection;importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.stereotype.Service;importcom.yonyou.hotusm.module.sys.dao.UserDao;importcom.yonyou.hotusm.module.sys.entity.User;importcom.yonyou.hotusm.module.sys.util.UserUtils;
@ServicepublicclassSystemAuthorizingRealmextendsAuthorizingRealm{
@AutowiredprivateUserDao userDao;
@OverrideprotectedAuthorizationInfo doGetAuthorizationInfo(
PrincipalCollection principals) {
SimpleAuthorizationInfo info=newSimpleAuthorizationInfo();
info.addStringPermission("sys:manager");
info.addStringPermission("user");
System.out.println("开始授权");returninfo;
}
@OverrideprotectedAuthenticationInfo doGetAuthenticationInfo(
AuthenticationToken token)throwsAuthenticationException {
UsernamePasswordToken upToken=(UsernamePasswordToken) token;
String username=upToken.getUsername();
String password=newString(upToken.getPassword());
User user=newUser();
user.setLoginName(username);
user=userDao.get(user);
System.out.println("===========");if(user!=null){if(user.getPassword().equals(password)){returnnewSimpleAuthenticationInfo(username,password,getName());
}
}thrownewUnauthenticatedException();
}publicstaticclassPrincipalimplementsSerializable {privatestaticfinallongserialVersionUID = 1L;privateString id;//编号privateString loginName;//登录名privateString name;//姓名publicPrincipal(User user) {this.id =user.getId();this.loginName =user.getLoginName();this.name =user.getName();
}publicString getId() {returnid;
}publicString getLoginName() {returnloginName;
}publicString getName() {returnname;
}/*** 获取SESSIONID*/publicString getSessionid() {try{return(String) UserUtils.getSession().getId();
}catch(Exception e) {return"";
}
}
@OverridepublicString toString() {returnid;
}
}
}
看的出来,其中最重要的是doGetAuthorizationInfo和doGetAuthenticationInfo,这两个方法,doGetAuthorizationInfo是对当前的用户进行授权的,至于授权的时期,就是当用户需要验证的时候,我这里只是简单的写死了,但是在实际项目开发中,我们一般会将权限存放在数据表中,所以真实情况是先到数据库中查出一个集合,然后迭代授权,
doGetAuthenticationInfo对于的是对用户验证,这里我们就需要从数据库中根据用户查出用户,根据用户情况,抛出不用的异常。
下面就是讲解sessionManager,因为Shiro有自己的一套session体系,有sessionManager就不奇怪了,sessionManager主要职责是管理session的创建和删除,特别提一下,sessionManager对session的操作,其实只是调用了sessionDAO,然再加上自己的一些操作,所以,我们可以看到sessionManager的bean还依赖sessionDAO,下面是自己实现的sessionManager:

看代码就明白,其实就是对session的操作,
还有就是sessionDAO了,这个sessionDAO才是真正对session操作的bean:

}
,看sessionDAO还有一个idGen依赖bean,指的是id的生成策略,这个bean也是自己定义的,但是需要继承SessionIdGenerator,其中就有public Serializable generateId(Session session),返回的就是session的id,至于shiroCacheManager我们前面已经讲过了,就是session的缓存,我们使用的底层是cacheManager.
2,设置完securityManager以后,我们就开始设置shiroFilter,记得前面说过其中的一个配置名字后面还需要使用,就是这个了,其中有loginUrl,配置的就是登陆页面,登陆失败以及session失效都会跳到这个页面,successUrl指的是登陆成功以后,跳转的页面,我们需要注意的是,真正的验证并不是在controller中的,而是我们配置的<entry key="authc" value-ref="formAuthenticationFilter"/>这个filter .既然说到filter 那么就详细的讲一下这个filter怎么配置,我们看到在
<propertyname="filterChainDefinitions"><refbean="shiroFilterChainDefinitions"/></property>
配置了一连串的字符串,这个其实也很好看出来,这些就是制定特定的url进行拦截的,而这些拦截就是使用filter的,而filter就是在
<propertyname="filters"><map><entrykey="cas"value-ref="casFilter"/><entrykey="authc"value-ref="formAuthenticationFilter"/><entrykey="outdate"value-ref="sessionOutDateFilter"/></map></property>
配置,配置了以后,我们就能在filterChainDefinitions使用这个key了,shiro提供了一部分的filter:

anon: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
当然,我们自己也可以自定义的。像<entry key="outdate" value-ref="sessionOutDateFilter"/>,就是自己定义的,最底层就是过滤器,下面是我实现的一个filter:
packagecom.thinkgem.jeesite.common.security.shiro.session;importjava.io.PrintWriter;importjavax.servlet.ServletRequest;importjavax.servlet.ServletResponse;importjavax.servlet.http.HttpServletRequest;importjavax.servlet.http.HttpServletResponse;importorg.apache.shiro.web.servlet.AdviceFilter;importcom.thinkgem.jeesite.modules.sys.security.SystemAuthorizingRealm.Principal;importcom.thinkgem.jeesite.modules.sys.utils.UserUtils;/***

Principal principal=UserUtils.getPrincipal();
HttpServletRequest req=(HttpServletRequest) request;
String uri=req.getRequestURI();if(uri.endsWith(frontUrl)|loginUrl.equals(uri)|(principal!=null&&!principal.isMobileLogin())){returntrue;
}try{
issueRedirect(request,response,redirectUrl);
}catch(Exception e) {
e.printStackTrace();
}returnfalse;
}protectedvoidissueRedirect(ServletRequest request, ServletResponse response, String redirectUrl)throwsException
{
String url="<a href="+redirectUrl+" target=\"_blank\" onclick=\"custom_close()\">重新连接<a/> ";
HttpServletResponse resp=(HttpServletResponse) response;
HttpServletRequest req=(HttpServletRequest) request;
response.setContentType("text/html;charset=UTF-8");
PrintWriter out=resp.getWriter();
out.print("<script language='Javascript'>");
out.print("function custom_close(){" +
"self.opener=null;" +
"self.close();}");
out.print("</script>");
out.print("验证信息出错,请点击"+url);
}publicString getRedirectUrl() {returnredirectUrl;
}publicvoidsetRedirectUrl(String redirectUrl) {this.redirectUrl =redirectUrl;
}publicString getLoginUrl() {returnloginUrl;
}publicvoidsetLoginUrl(String loginUrl) {this.loginUrl =loginUrl;
}
}
3.需要注意一点是formAuthenticationFilter是登陆以后,身份验证的入口,但是只拦截POST方式的loginUrl,就是我们前面配置的那个url,成功以后会跳到我们配置的那个成功页面,一般我们都是设置一个虚拟路径,然后在controller跳转页面:
/*** 登录成功,进入管理首页*/@RequiresPermissions("user")
@RequestMapping(value= "${adminPath}")publicString index(HttpServletRequest request, HttpServletResponse response) {
Principal principal=UserUtils.getPrincipal();
List<String> str=commentService.commentList(null);//System.out.println(JsonMapper.toJsonString(str));//登录成功后,验证码计算器清零isValidateCodeLogin(principal.getLoginName(),false,true);if(logger.isDebugEnabled()){
logger.debug("show index, active session size: {}", sessionDAO.getActiveSessions(false).size());
}//如果已登录,再次访问主页,则退出原账号。if(Global.TRUE.equals(Global.getConfig("notAllowRefreshIndex"))){
String logined= CookieUtils.getCookie(request, "LOGINED");if(org.apache.commons.lang3.StringUtils.isBlank(logined) || "false".equals(logined)){
CookieUtils.setCookie(response,"LOGINED", "true");
}elseif(org.apache.commons.lang3.StringUtils.equals(logined, "true")){
UserUtils.getSubject().logout();return"redirect:" + adminPath + "/login";
}
}/return"modules/sys/sysIndex";
}
下面是authc对应的那个filter的代码,
@ServicepublicclassFormAuthenticationFilterextendsorg.apache.shiro.web.filter.authc.FormAuthenticationFilter {publicstaticfinalString DEFAULT_CAPTCHA_PARAM = "validateCode";publicstaticfinalString DEFAULT_MOBILE_PARAM = "mobileLogin";publicstaticfinalString DEFAULT_MESSAGE_PARAM = "message";privateString captchaParam =DEFAULT_CAPTCHA_PARAM;privateString mobileLoginParam =DEFAULT_MOBILE_PARAM;privateString messageParam =DEFAULT_MESSAGE_PARAM;
