session过期 点击跳转到登陆页
自己总结的:
package cn.com.**.**.personalCenter.filter;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
public class SessionFilter implements Filter{
private static final int NOT_VALID = -1;
@Override
public void init(FilterConfig filterConfig) throws ServletException {
// TODO Auto-generated method stub
}
@Override
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
HttpServletRequest httpRequest = (HttpServletRequest) request;
httpRequest.setCharacterEncoding("UTF-8");
HttpSession session = httpRequest.getSession();
String oneOfLoginUrl = "http://localhost:8020/ecenter/views/ecenterClub/loginRegisterNew/newloginClub.jsp";
String requestURI = httpRequest.getRequestURI();
// String path = url.substring(url.lastIndexOf("/"));
// boolean isLogin = requestURI.indexOf("login.jsp") != NOT_VALID || requestURI.indexOf("newloginClub.jsp") != NOT_VALID;//这个对loginRegisterNew中的文件会失效
boolean isLogin = requestURI.indexOf("login") != NOT_VALID;//这样不会过滤部分样式和js文件就能正常显示了
//超时处理,ajax请求超时设置超时状态,页面请求超时则返回提示并重定向
// if((path.indexOf(".jsp") != -1) && (session.getAttribute("entryId") == null) && (path.equals("/login.jsp") == false)){
if(!isLogin && (session.getAttribute("entryId") == null || "".equals(session.getAttribute("entryId")))){
//判断是否为ajax请求
// if(httpRequest.getHeader("x-requested-with") != null && httpRequest.getHeader("x-requested-with").equalsIgnoreCase("XMLHttpRequest")){
// httpResponse.addHeader("sessionStatus", "timeOut");
// httpResponse.addHeader("loginPath", oneOfLoginUrl);
// } else {
String str = "";
response.setContentType("text/html;charset=UTF-8");//解决中文乱码
try{
//response到请求页
PrintWriter writer = response.getWriter();
writer.write(str);
writer.flush();
writer.close();
} catch (Exception e){
e.printStackTrace();
}
// }
} else {
chain.doFilter(request, response);
}
}
@Override
public void destroy() {
// TODO Auto-generated method stub
}
}
如果登陆页没有除缓存最好在
response.setContentType(
"text/html;charset=UTF-8"
);
// 解决中文乱码
后边加上
response.setHeader("Pragma","No-cache");
response.setHeader("Cache-Control","no-cache");
response.setHeader("Cache-Control", "no-store");
response.setDateHeader("Expires",0);实际项目:
