我有一个java spring mvc webapp，它构建一个状态表，使ajax调用每3秒更新一次ping状态，每5分钟更新一次性能/健康状态。它工作正常，但唯一的事情是我添加了spring安全性，每当第二个用户从另一个页面登录时，它会重置两个视图而不是仅构建新视图。如何使其成为每个新用户会话都有自己的更新视图而不影响其他打开的浏览器会话？
这是我的jsp页面：
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@page session="true" %>
<html>
<head>
<title>Site Connector</title>
<link rel="stylesheet" type="text/css" href="pages/styles/main.css">
<link rel="colorSchemeMapping" href="pages/styles/colorschememapping.xml">
<script type="text/javascript" src="pages/scripts/jquery-1.11.2.min.js"></script>
<script type="text/javascript">
function updateReachability() {
$.ajax({
url: 'updatePing',
type: 'GET',
success: function(data) {
$('#site').html(data);
}
});
}
function updateStatus() {
$.ajax({
url: 'updateStatus',
type: 'GET',
success: function(data) {
$('#site').html(data);
}
});
}
document.addEventListener('DOMContentLoaded', function() {
updateStatus();
setInterval(updateStatus, 300000);
setInterval(updateReachability, 3000);
}, false);
</script>
</head>

这是我的控制器类：
@Controller
public class SiteController {
private static final Logger logger = Logger.getLogger(SiteController.class.getName());
private static String osName = System.getProperty("os.name");
private SiteManager manager = new SiteManager();
private SiteStatus site = new SiteStatus();
private ModelAndView model = new ModelAndView("SiteConnectorPage");
private boolean checkPing = true;
//method to run on initialization to build site list table from file
@RequestMapping("/connector")
public ModelAndView init() {
System.out.println("Connector method called");
//call method to create the list of error codes to search for
try
{
if(osName.matches("^.*Windows.*$"))
{
//change file location to C:/SVP/hub-connector/site-list/SiteList.csv
site = manager.buildSiteStatus("C:/p4_dominer/SiteConnector/SiteList.csv", site);
//set the ping status and URL's for each hub
if(!site.getHubs().isEmpty())
{
//set URL's for each hub and determines their reachability status
manager.buildURL(site.getHubs(), true);
}
else
{
logger.error("Site List is empty, please check contents of input file");//throw empty list exception
}
}

{
site = manager.buildSiteStatus("/home/engineering/SVP/site-connector/site-list/SiteList.csv", site);
if(!site.getHubs().isEmpty())
{

manager.buildURL(site.getHubs(), false);
}
else
{
logger.error("Site List is empty, please check contents of input file");//throw empty list exception
}
}
}
catch (IOException e)
{
logger.error(e.getMessage());
}
model.addObject("site", site);
return model;
}
//method to update ping status
@RequestMapping(value = "/updatePing", method = RequestMethod.GET)

}
else

//set URL's for each hub and determines their reachability status
manager.buildURL(site.getHubs(), false);
}
}
catch (IOException e)
{
logger.error(e.getMessage());
}
}
return model;
}
@RequestMapping(value="/customLogin", method = RequestMethod.GET)
public ModelAndView loginPage(@RequestParam(value="error", required=false) String error,
@RequestParam(value="logout", required=false) String logout)
{
ModelAndView loginModel = new ModelAndView("customLogin");
if(error != null) {
loginModel.addObject("error", "Login was unsuccessful, Please Try Again.");
}
if(logout != null) {
loginModel.addObject("msg", "You've been logged out successfully.");
}
return loginModel;
}
@RequestMapping(value="/updateStatus", method = RequestMethod.GET)
public ModelAndView updateStatus()
{
System.out.println("updateStatus method called");
//set checkPing to false so updatePingStatus method doesn't update model concurrentlly which was causing the table to flash
checkPing = false;
if(osName.matches("^.*Windows.*$"))
{
/*test code */long startTime = System.nanoTime();
manager.getStatusData(site.getHubs(), site.getDeviceErrors(), true);
/*test code */long endTime = System.nanoTime();
/*test code */long duration = (endTime - startTime) / 1000000;
/*test code*/logger.info("updateStatus took " + duration + " ms");
}
else
{
manager.getStatusData(site.getHubs(), site.getDeviceErrors(), false);
}
checkPing = true;
return model;
}
}

答案 0 :(得分：0)
经过大量的谷歌搜索后，终于想出了答案。我在会话控制器类中添加了会话，以便每个客户端请求都更新自己的会话对象，而不会影响其他打开的浏览器。
@RequestMapping("/connector")
public ModelAndView init(HttpServletRequest request) {
SiteManager manager = new SiteManager();
ModelAndView model = new ModelAndView("SiteConnectorPage");
SiteStatus siteStatus = new SiteStatus();
//create session if one doesn't exist
HttpSession session = request.getSession(true);
System.out.println("Connector method called");
try
{
if(osName.matches("^.*Windows.*$"))
{
siteStatus = manager.buildSiteStatus("C:/SICK/Site Connector/SiteList.csv");
//set the ping status and URL's for each hub
if(!siteStatus.getHubs().isEmpty())
{
//set URL's for each hub and determines their reachability status
manager.buildURL(siteStatus.getHubs(), true);
}
else
{
logger.error("Site List is empty, please check contents of input file");//throw empty list exception
}
}
else //path to Linux location
{
siteStatus = manager.buildSiteStatus("/home/engineering/SVP/site-connector/site-list/SiteList.csv");
if(!siteStatus.getHubs().isEmpty())
{
//set URL's for each hub and determines their reachability status
manager.buildURL(siteStatus.getHubs(), false);
}
else
{
logger.error("Site List is empty, please check contents of input file");//throw empty list exception
}
}
}
catch (IOException e)
{
logger.error(e.getMessage());
}
session.setAttribute("site", siteStatus);
model.addObject("site", siteStatus);
return model;
}
