shiro+cas微服务化笔记

1.SpringBoot配置

有如下两个配置文件：ShiroBaseConfig.java

importlombok.extern.log4j.Log4j;
importorg.apache.shiro.cache.CacheManager;
importorg.apache.shiro.cache.MemoryConstrainedCacheManager;
importorg.apache.shiro.cas.CasFilter;
importorg.apache.shiro.codec.Base64;
importorg.apache.shiro.session.mgt.eis.MemorySessionDAO;
importorg.apache.shiro.web.mgt.CookieRememberMeManager;
importorg.apache.shiro.web.servlet.SimpleCookie;
importorg.springframework.beans.factory.annotation.Value;
importorg.springframework.context.annotation.Bean;
importorg.springframework.context.annotation.Configuration;

/**
*
*Description:shiro权限管理模块conf
*
*@authorDean.Hwang
*@date17/5/18
*/
@Configuration
@Log4j
publicclassShiroBaseConfiguration{
@Value("${cas.server.url.prefix}")
privateStringcasPrefix;
@Value("${cas.service}")
privateStringcasService;

/**
*会话Cookie模板
*
*@return
*/
@Bean
publicSimpleCookiesessionIdCookie(){
SimpleCookiesimpleCookie=newSimpleCookie("sid");
simpleCookie.setHttpOnly(true);
simpleCookie.setMaxAge(1800000);
returnsimpleCookie;
}

/**
*会话Cookie模板
*
*@return
*/
@Bean
publicSimpleCookierememberCookie(){
SimpleCookiesimpleCookie=newSimpleCookie("rememberMe");
simpleCookie.setHttpOnly(true);
simpleCookie.setMaxAge(2592000);//30天
returnsimpleCookie;
}

/**
*rememberMe管理器
*
*@return
*/
@Bean
publicCookieRememberMeManagerrememberMeManager(SimpleCookierememberCookie){
CookieRememberMeManagercookieRememberMeManager=newCookieRememberMeManager();
cookieRememberMeManager.setCipherKey(Base64.decode(""));//rememberMecookie加密的密钥建议每个项目都不一样默认AES算法密钥长度（128256512位）
cookieRememberMeManager.setCookie(rememberCookie);
returncookieRememberMeManager;
}

/**
*会话DAO
*
*@return
*/
@Bean
publicMemorySessionDAOsessionDAO(){
returnnewMemorySessionDAO();
}


@Bean
publicCacheManagershiroCacheManager(){
returnnewMemoryConstrainedCacheManager();
}

@Bean
publicKryCasRealmcasRealm(CacheManagershiroCacheManager){
returnnewKryCasRealm(casPrefix,casService,shiroCacheManager);
}

@Bean
publicCasFiltercasFilter(){
CasFiltercasFilter=newCasFilter();
casFilter.setEnabled(true);
casFilter.setName("casFilter");
casFilter.setFailureUrl("/authority/casFailure");
returncasFilter;
}


}

下面ShiroManagerConfiguration.java文件

importorg.apache.shiro.cache.CacheManager;
importorg.apache.shiro.cas.CasFilter;
importorg.apache.shiro.cas.CasSubjectFactory;
importorg.apache.shiro.spring.web.ShiroFilterFactoryBean;
importorg.apache.shiro.web.filter.authc.LogoutFilter;
importorg.apache.shiro.web.mgt.CookieRememberMeManager;
importorg.apache.shiro.web.mgt.DefaultWebSecurityManager;
importorg.apache.shiro.web.session.mgt.ServletContainerSessionManager;
importorg.springframework.beans.factory.annotation.Autowired;
importorg.springframework.beans.factory.annotation.Value;
importorg.springframework.beans.factory.config.MethodInvokingFactoryBean;
importorg.springframework.boot.autoconfigure.AutoConfigureAfter;
importorg.springframework.context.annotation.Bean;
importorg.springframework.context.annotation.Configuration;

importjavax.servlet.Filter;
importjava.util.HashMap;
importjava.util.Map;

/**

@Configuration
@AutoConfigureAfter(
{ShiroBaseConfiguration.class}
)
publicclassShiroManagerConfiguration{
@Autowired
privateKryCasRealmkryCasRealm;
@Autowired
privateCacheManagershiroCacheManager;
@Autowired
privateCookieRememberMeManagerrememberMeManager;
@Value("${cas.server.login.url}")
privateStringloginUrl;
@Value("${cas.client.url.prefix}")
privateStringurlPrefix;
@Autowired
privateCasFiltercasFilter;
@Value("${cas.server.logout.url}")
privateStringlogoutUrl;
@Value("${cas.client.index.url}")
privateStringindexUrl;

@Bean
publicDefaultWebSecurityManagersecurityManager(){
DefaultWebSecurityManagersecurityManager=newDefaultWebSecurityManager();
securityManager.setRealm(kryCasRealm);
securityManager.setSessionManager(newServletContainerSessionManager());
securityManager.setCacheManager(shiroCacheManager);
securityManager.setRememberMeManager(rememberMeManager);
securityManager.setSubjectFactory(newCasSubjectFactory());
returnsecurityManager;
}

/**
*相当于调用SecurityUtils.setSecurityManager(securityManager)
*
*@paramsecurityManager
*@return
*/
@Bean
publicMethodInvokingFactoryBeanmethodInvokingFactoryBean(DefaultWebSecurityManagersecurityManager){
MethodInvokingFactoryBeanbean=newMethodInvokingFactoryBean();
bean.setStaticMethod("org.apache.shiro.SecurityUtils.setSecurityManager");
bean.setArguments(newObject[]{securityManager});
returnbean;
}

@Bean
publicShiroFilterFactoryBeanshiroFilter(DefaultWebSecurityManagersecurityManager){
ShiroFilterFactoryBeanfactoryBean=newShiroFilterFactoryBean();
factoryBean.setSecurityManager(securityManager);
factoryBean.setLoginUrl(loginUrl+serviceStr+urlPrefix+"/cas");
factoryBean.setSuccessUrl("../mind/index.do");
factoryBean.setUnauthorizedUrl("/unauthorized.jsp");
MapfilterMap=newHashMap<>();
filterMap.put("cas",casFilter);
filterMap.put("user",portalUserFilter);
//只能在这里初始化LogoutFilter，不然会被springboot注册到/*
PortalLogoutFilterlogoutFilter=newPortalLogoutFilter();
logoutFilter.setRedirectUrl(logoutUrl+serviceStr+indexUrl);
filterMap.put("logout",logoutFilter);
factoryBean.setFilters(filterMap);
Mapfilters=newHashMap<>();
filters.put("/casFailure.jsp","anon");
filters.put("/js/**","anon");
filters.put("/themes/**","anon");
filters.put("/3rdOauth/**","anon");
filters.put("/cas","cas");
filters.put("/logout","logout");
filters.put("/**","user");
factoryBean.setFilterChainDefinitionMap(filters);
returnfactoryBean;}
}

2.UserFilter的改造

2.1改造的原因：

因为，我们现在新的服务器架构是前后端完全分离的。但是，shiro是不支持完全的前后端分离。所以导致了单点登录完成以后会跳转至接口，而不是目标页面。同时，由于历史原因，我们的cas验证服务器与业务服务器不是同一个域。如果，需要在服务器端进行重定向就必须要通过跨域，考虑到跨域会有风险。所以，我也将sso服务器登录重定向进行了重构。做成了返回json，前端在接收到json自己进行登录页跳转。

具体的实现代码如下:

protectedvoidsaveRequestAndRedirectToLogin(ServletRequestrequest,ServletResponseresponse)throwsIOException{
Sessionsession=SecurityUtils.getSubject().getSession();
if(session!=null){
SavedRequestsavedRequest=newPortalSavedRequest(WebUtils.toHttp(request));//重写的SavedRequest，具体处理由不同的业务需求自定
session.setAttribute(SAVED_REQUEST_KEY,savedRequest);

}
PrintWriterout=null;
try{
ResultVO
