本文執行個體為大家分享了Shiro Cas微服務化及前後端完全分離，供大家參考，具體内容如下
shiro+cas微服務化筆記
1.Spring Boot 配置
有如下兩個配置檔案：ShiroBaseConfig.java
import lombok.extern.log4j.Log4j;
import org.apache.shiro.cache.CacheManager;
import org.apache.shiro.cache.MemoryConstrainedCacheManager;
import org.apache.shiro.cas.CasFilter;
import org.apache.shiro.codec.Base64;
import org.apache.shiro.session.mgt.eis.MemorySessionDAO;
import org.apache.shiro.web.mgt.CookieRememberMeManager;
import org.apache.shiro.web.servlet.SimpleCookie;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
@Log4j
public class ShiroBaseConfiguration {
@Value("${cas.server.url.prefix}")
private String casPrefix;
@Value("${cas.service}")
private String casService;
@Bean
public SimpleCookie sessionIdCookie() {
SimpleCookie simpleCookie = new SimpleCookie("sid");
simpleCookie.setHttpOnly(true);
simpleCookie.setMaxAge(1800000);
return simpleCookie;
}
@Bean
public SimpleCookie rememberCookie() {
SimpleCookie simpleCookie = new SimpleCookie("rememberMe");
simpleCookie.setHttpOnly(true);
simpleCookie.setMaxAge(2592000);//30天
return simpleCookie;
}
@Bean
public CookieRememberMeManager rememberMeManager(SimpleCookie rememberCookie) {
CookieRememberMeManager cookieRememberMeManager = new CookieRememberMeManager();
cookieRememberMeManager.setCipherKey(Base64.decode(""));// rememberMe cookie加密的密鑰 建議每個項目都不一樣 預設AES算法 密鑰長度(128 256 512 位)
cookieRememberMeManager.setCookie(rememberCookie);
return cookieRememberMeManager;
}
@Bean
public MemorySessionDAO sessionDAO() {
return new MemorySessionDAO();
}
@Bean
public CacheManager shiroCacheManager() {
return new MemoryConstrainedCacheManager();
}
@Bean
public KryCasRealm casRealm(CacheManager shiroCacheManager) {
return new KryCasRealm(casPrefix, casService, shiroCacheManager);
}
@Bean
public CasFilter casFilter() {
CasFilter casFilter = new CasFilter();
casFilter.setEnabled(true);
casFilter.setName("casFilter");
casFilter.setFailureUrl("/authority/casFailure");
return casFilter;
}
}
下面ShiroManagerConfiguration.java 檔案
import org.apache.shiro.cache.CacheManager;
import org.apache.shiro.cas.CasFilter;
import org.apache.shiro.cas.CasSubjectFactory;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.filter.authc.LogoutFilter;
import org.apache.shiro.web.mgt.CookieRememberMeManager;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.apache.shiro.web.session.mgt.ServletContainerSessionManager;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.beans.factory.config.MethodInvokingFactoryBean;
import org.springframework.boot.autoconfigure.AutoConfigureAfter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import javax.servlet.Filter;
import java.util.HashMap;
import java.util.Map;
@Configuration
@AutoConfigureAfter(
{ShiroBaseConfiguration.class}
)
public class ShiroManagerConfiguration {
@Autowired
private KryCasRealm kryCasRealm;
@Autowired
private CacheManager shiroCacheManager;
@Autowired
private CookieRememberMeManager rememberMeManager;
@Value("${cas.server.login.url}")
private String loginUrl;
@Value("${cas.client.url.prefix}")
private String urlPrefix;
@Autowired
private CasFilter casFilter;
@Value("${cas.server.logout.url}")
private String logoutUrl;
@Value("${cas.client.index.url}")
private String indexUrl;
@Bean
public DefaultWebSecurityManager securityManager() {
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
securityManager.setRealm(kryCasRealm);
securityManager.setSessionManager(new ServletContainerSessionManager());
securityManager.setCacheManager(shiroCacheManager);
securityManager.setRememberMeManager(rememberMeManager);
securityManager.setSubjectFactory(new CasSubjectFactory());
return securityManager;
}
@Bean
public MethodInvokingFactoryBean methodInvokingFactoryBean(DefaultWebSecurityManager securityManager) {
MethodInvokingFactoryBean bean = new MethodInvokingFactoryBean();
bean.setStaticMethod("org.apache.shiro.SecurityUtils.setSecurityManager");
bean.setArguments(new Object[]{securityManager});
return bean;
}
@Bean
public ShiroFilterFactoryBean shiroFilter(DefaultWebSecurityManager securityManager) {
ShiroFilterFactoryBean factoryBean = new ShiroFilterFactoryBean();
factoryBean.setSecurityManager(securityManager);
factoryBean.setLoginUrl(loginUrl + serviceStr + urlPrefix + "/cas");
factoryBean.setSuccessUrl("../mind/index.do");
factoryBean.setUnauthorizedUrl("/unauthorized.jsp");
Map filterMap = new HashMap<>();
filterMap.put("cas", casFilter);
filterMap.put("user", portalUserFilter);
//隻能在這裡初始化LogoutFilter，不然會被spring boot注冊到
public class PortalCasFilter extends CasFilter {
@Override
protected void issueSuccessRedirect(ServletRequest request, ServletResponse response) throws Exception {
String successUrl = ((ShiroHttpServletRequest) request).getHeader("page-url");//前端頁面在請求的時候在header中帶上請求這個接口的url。這樣便将登入成功後需要跳轉的位址綁定到了對應的Subject對象中。以便于在登入以後跳轉到這個頁面
if (StringUtil.isBlank(successUrl)) {
WebUtils.redirectToSavedRequest(request, response, getSuccessUrl());
} else {
WebUtils.redirectToSavedRequest(request, response, successUrl);
}
}
}
#4.使用者安全的退出
後期發現直接依靠原有的logout會發生session未登出的情況。是以重寫了LogoutFilter。登出的時候直接調用配置的URL即可
public class PortalLogoutFilter extends AdviceFilter {
private static final Logger log = LoggerFactory.getLogger(LogoutFilter.class);
public static final String DEFAULT_REDIRECT_URL = "/";
private String redirectUrl = DEFAULT_REDIRECT_URL;
@Override
protected boolean preHandle(ServletRequest request, ServletResponse response) throws Exception {
Subject subject = getSubject(request, response);
String redirectUrl = getRedirectUrl(request, response, subject);
//try/catch added for SHIRO-298:
try {
subject.logout();
Session session = subject.getSession();
session.stop();
} catch (SessionException ise) {
log.debug("Encountered session exception during logout. This can generally safely be ignored.", ise);
}
issueRedirect(request, response, redirectUrl);
return false;
}
}
以上就是本文的全部内容，希望對大家的學習有所幫助，也希望大家多多支援我們。
