###                              springboot设置session监听器 ###

1.添加session管理器

package com.sinosoft.session.server;
    
    import java.util.HashMap;
    import javax.servlet.http.HttpSession;
    
    /**
     * Created by  lijunming
     * on  date 2018-09-20
     * session管理器
     * time 20:01
     */
    public class MySessionContext {
        private static HashMap mymap = new HashMap();
    
        public static synchronized void AddSession(HttpSession session) {
            if (session != null) {
                mymap.put(session.getId(), session);
            }
        }
    
        public static synchronized void DelSession(HttpSession session) {
            if (session != null) {
                mymap.remove(session.getId());
            }
        }
    
        public static synchronized HttpSession getSession(String session_id) {
            if (session_id == null)
                return null;
            return (HttpSession) mymap.get(session_id);
        }
    
    }

2.添加session监听器

package com.sinosoft.session.server;
    
    import org.springframework.stereotype.Component;
    
    import javax.servlet.http.HttpSession;
    import javax.servlet.http.HttpSessionEvent;
    import javax.servlet.http.HttpSessionListener;
    
    /**
     * Created by  lijunming
     * on  date 2018-09-20
     * session监听器
     * time 20:02
     */
    @Component
    public class MySessionListener implements HttpSessionListener {
        @Override
        public void sessionCreated(HttpSessionEvent httpSessionEvent) {
            System.out.println("session正在創建");
            MySessionContext.AddSession(httpSessionEvent.getSession());
        }
    
        @Override
        public void sessionDestroyed(HttpSessionEvent httpSessionEvent) {
            HttpSession session = httpSessionEvent.getSession();
            System.out.println("session注銷中");
            MySessionContext.DelSession(session);
        }
    }

3.登录的时候设置session超时时间

package com.ocrweb.controller;
    
    import com.etop.common.pojo.ResponseResult;
    import com.etop.common.util.IpAddrUtil;
    import com.ocrweb.entity.SysModel;
    import com.ocrweb.entity.SysUser;
    import com.ocrweb.pojo.SessionKey;
    import com.ocrweb.service.SysModelService;
    import com.ocrweb.service.SysUserService;
    import com.ocrweb.sso.AgentThreadLocal;
    import com.ocrweb.sso.CurrentUser;
    import com.ocrweb.vo.UserVo;
    import org.apache.shiro.SecurityUtils;
    import org.apache.shiro.authc.UsernamePasswordToken;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.util.StringUtils;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    import org.springframework.web.servlet.ModelAndView;
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpSession;
    import java.util.List;
    
    /**
     * 不需要权限既能访问的接口
     */
    @Controller
    public class ExportController {
    
     
        /**
         * 登录页
         */
        @GetMapping("/login")
        public String toUserLogin() {
            return "user/login";
        }
    
    
    
        /**
         * 登录
         */
        @ResponseBody
        @RequestMapping(value = "toLogin.do", produces = "application/json")
        public ResponseResult login(String loginName, String password,HttpSession session) {
            if(StringUtils.isEmpty(loginName) || StringUtils.isEmpty(password)){
                return new ResponseResult(false,"参数丢失!");
            }
            ResponseResult requestResult = sysUserService.findByLoginNameAndPassword(loginName, password);
            if (requestResult.isSuccess()) {
                //session的实效时间,单位为秒
                session.setMaxInactiveInterval(1800);
            }
            return requestResult;
        }
    
    
    
    }
