前言：
此时朋友们对“easyui menubutton”大致比较讲究，看官们都想要学习一些“easyui menubutton”的相关知识。那么小编也在网络上网罗了一些对于“easyui menubutton””的相关知识，希望小伙伴们能喜欢，兄弟们一起来了解一下吧！shiro集成spring使用cas单点登录配置
（一）shiro单点登录
配置的主要目的在于将登录页面改为${cas.server}?service=${cas.client}/login的形式，service后面为本地的回调地址。在cas服务器端登录成功后，会生成ticket返回给客户端，客户端的shiro使用ticket最为凭据保存起来。
shiro配置单点登陆后，在注销时原始的cas-client只能删除HttpSession，不能删除shiro的Session，因此未使用shiro的session管理器。
如果想启用shiro的Session管理器，可以参考Shiro & CAS 实现单点登录。
原有的CasRealm在AuthenticationInfo中只保存了用户名作为principal，MyCasRealm中重写了此方法，改为保存用户信息类。
需要在pom增加依赖，shiro-cas会通过依赖传递自动增加cas-client-core-3.2.1的依赖。

2、cas.properties
cas.server=
cas.client=
3、自定义Realm实现
主要修改了CasRealm的doGetAuthenticationInfo()方法，CasRealm默认只保存了username，本系统改为保存ShiroUser对象。
public class MyCasRealm extends CasRealm {
Logger logger = LoggerFactory.getLogger(MyCasRealm.class);
@Autowired
private UcsUserService ucsUserService;
@Autowired
private UcsRoleService ucsRoleService;
@Autowired
private UcsPermissionService ucsPermissionService;
@Value("${domain}")
private String domain;
/**
* 授权查询回调函数, 进行鉴权但缓存中无用户的授权信息时调用.
*
* @see org.apache.shiro.realm.AuthorizingRealm#doGetAuthorizationInfo(org.apache.shiro.subject.PrincipalCollection)
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
ShiroUser shiroUser = (ShiroUser) principals.getPrimaryPrincipal();
UcsUser ucsUser = ucsUserService.selectByUsername(shiroUser.loginName);
//把principals放session中 key=userId value=principals
SecurityUtils.getSubject().getSession().setAttribute(String.valueOf(ucsUser.getId()),SecurityUtils.getSubject().getPrincipals());
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
//赋予角色
List<UcsRole> ucsRoles = ucsRoleService.selectByUser(ucsUser.getId());
if (!CheckEmptyUtil.isEmpty(ucsRoles)){
for(UcsRole ucsRole:ucsRoles){
info.addRole(ucsRole.getId());
}
}
//赋予权限
// List<UcsPermission> ucsPermissions = ucsPermissionService.selectByUser(ucsUser.getId(), domain);
if (!CheckEmptyUtil.isEmpty(shiroUser.getMenus())){
for(EasyUIMenu permission:shiroUser.getMenus()){
if(UcsBaseConstant.PermissionType.BUTTON.equals(permission.getType()))
info.addStringPermission(permission.getUrl());
}
}
return info;
}
/**

*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
CasToken casToken = (CasToken) token;
if (token == null) {
return null;
}
String ticket = (String)casToken.getCredentials();

}
TicketValidator ticketValidator = ensureTicketValidator();
try {
// contact CAS server to validate service ticket

logger.debug("Validate ticket : {} in CAS server : {} to retrieve user : {}", new Object[]{
ticket, getCasServerUrlPrefix(), username

Map<String, Object> attributes = casPrincipal.getAttributes();
// refresh authentication token (user id + remember me)

String rememberMeStringValue = (String)attributes.get(rememberMeAttributeName);
boolean isRemembered = rememberMeStringValue != null && Boolean.parseBoolean(rememberMeStringValue);
if (isRemembered) {
casToken.setRememberMe(true);
}
// create simple authentication info
// 根据用户名获取账号信息
UcsUser ucsUser = ucsUserService.selectByUsername(username);
List<UcsPermission> ucsPermissions = null;
if (ucsUser != null) {
ucsPermissions = ucsPermissionService.selectByUser(ucsUser.getId(), domain);
} else {
throw new UnknownAccountException();//登录失败
}
//给菜单排序
List<EasyUIMenu> menus = toEasyUIMenu(ucsPermissions);
if(!CheckEmptyUtil.isEmpty(menus)){
Collections.sort(menus);
}
ShiroUser shiroUser = new ShiroUser(ucsUser.getId(), ucsUser.getUsername(), ucsUser.getName(), menus);
return new SimpleAuthenticationInfo(shiroUser, ticket, getName());
} catch (TicketValidationException e) {
throw new CasAuthenticationException("Unable to validate ticket [" + ticket + "]", e);
}
}
private List<EasyUIMenu> toEasyUIMenu(List<UcsPermission> ucsPermissions){
List<EasyUIMenu> menus = new ArrayList<EasyUIMenu>(0);
for (UcsPermission ucsPermission : ucsPermissions) {
menus.add(toEasyUIMenu(ucsPermission));
}
return menus;
}
private EasyUIMenu toEasyUIMenu(UcsPermission ucsPermission){

（二）cas登出
在任意一个子系统登出后，cas服务器会向所有发过登录请求的子系统发送一个登出请求，使所有子系统的HttpSession失效。如果使用了shiro的session管理器，需要修改cas客户端代码，在移除HttpSession的时候也移除shiro的Session。
1、web.xml
web.xml中需要加入cas的SingleSignOutFilter实现单点登出功能，该过滤器需要放在shiroFilter之前，spring字符集过滤器之后。在实际使用时发现，SingleSignOutFilter如果放在了spring字符集过滤器之前，数据在传输过程中就会出现乱码。
<!-- 用于单点退出，该过滤器用于实现单点登出功能，可选配置。-->
<listener>
<listener-class>org.jasig.cas.client.session.SingleSignOutHttpSessionListener</listener-class>
</listener>
<!-- 该过滤器用于实现单点登出功能，可选配置。 -->
<filter>
<filter-name>CAS Single Sign Out Filter</filter-name>
<filter-class>org.jasig.cas.client.session.SingleSignOutFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>CAS Single Sign Out Filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

2、登出请求
登出只需要将当前页面跳转到cas服务器的logout页面即可实现登出。如果需要登出后跳转页面，可以加入service参数，并参考第一部分中第四节进行配置。
子系统使用的方法是在后台拼装好登出链接，发送给前台页面，前台页面接受使用el表达式接收。具体实现需要根据每个子系统的不同来自行实现。
@Value("${cas.server}")
private String cas_server;
@Value("${cas.client}")
private String cas_client;
@RequestMapping(value = "/index")
public String index(Model model){
StringBuilder logoutUrl = new StringBuilder();
logoutUrl.append(cas_server);
logoutUrl.append("/logout?service=");
logoutUrl.append(cas_client);
model.addAttribute("logoutUrl", logoutUrl.toString());
return "system/index";
}

前台页面：
<script>
var logoutUrl = '${logoutUrl}';
</script>

缓存配置（可选）
我使用的ehcache作为shiro的缓存，也可以使用其他的。
spring-cache.xml
