session失效时间
在Tomcat上,session的默认有效时间是30分钟。也可以通过配置文件修改session的有效时间。
1)修改web.xml

|
<!-- 设置session失效,单位分 -->
<session-config>
<session-timeout> 1 </session-timeout>
</session-config>
|
2).yml文件
1
2
|
server.session.cookie.http-only= #是否开启HttpOnly
server.session.timeout = #会话超时(秒)
|
使用过滤器获取session进行身份验证(未全部测试,慎用)
1)新建Filter

细心的读者会发现我用了AuthenticationUtil,这是为了将读写用户身份认证信息的功能分离而设计的工具类 2)AuthenticationUtil类

import org.apache.shiro.web.session.HttpServletSession;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
public class AuthenticationUtil {
private SessionKeyConfigProperties configProperties;
public AuthenticationUtil(SessionKeyConfigProperties configProperties) {
this .configProperties = configProperties;
}
/**
* 从session中获取用户的身份类型
* @param session
* @return 身份类型
*/
public UserTypeEnum getUserAuthentication(HttpSession session){
//获取session中的用户信息记录
Object userType = session.getAttribute(configProperties.getUserTypeKey());
//获取session中记录的用户类型
if (userType != null && userType instanceof UserTypeEnum) {
return (UserTypeEnum)userType;
}
return null ;
}
/**
* 将用户的身份写入session中
* @param session
* @param userType
*/
public void setUserAuthentication(HttpSession session,UserTypeEnum userType){
session.setAttribute(configProperties.getUserTypeKey(),userType);
}
}
|
3)配置文件SessiionKeyConfig.properties
user_type_key = userTypeKey
4)配置读取文件SessionKeyConfigProperties.class
