1，Ajax默认是不支持重定向的，只局部刷新数据，不跳转页面。
2，后台代码处理：
@RequestMapping("/updateCurrentUser")
public String updateCurrentUser(HttpServletRequest request, HttpServletResponse response, String type){
JsonObject json = new JsonObject();
String url = "";
if(type.equals("ADMIN_USER")){
Object s_user1 = request.getSession().getAttribute(Global.SESSION_ADMIN);
request.getSession().setAttribute("currentUser",s_user1);
request.getSession().setAttribute(Global.USER_ROLE,"ADMIN_USER");
url = "/jsp/console/backstageHome.jsp";
}
if(type.equals("MEDIATORS")){
Object s_user2 = request.getSession().getAttribute(Global.SESSION_MEDIATOR);
request.getSession().setAttribute("currentUser",s_user2);
request.getSession().setAttribute(Global.USER_ROLE,"MEDIATORS");
url = "/case/listMe";
}
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort()+request.getContextPath();
//如果request.getHeader("X-Requested-With") 返回的是"XMLHttpRequest"说明就是ajax请求，需要特殊处理
if("XMLHttpRequest".equals(request.getHeader("X-Requested-With"))){
//告诉ajax我是重定向
response.setHeader("REDIRECT", "REDIRECT");
//告诉ajax我重定向的路径
response.setHeader("CONTENTPATH", basePath+url);
response.setStatus(HttpServletResponse.SC_FORBIDDEN);
}
return null;
}
3.前端代码处理：
var jqxhr;
//设置ajax请求完成后运行的函数,
$.ajaxSetup({
complete:function(){
if("REDIRECT" == jqxhr.getResponseHeader("REDIRECT")){ //若HEADER中含有REDIRECT说明后端想重定向，
var win = window;
while(win != win.top){
win = win.top;
}
win.location.href = jqxhr.getResponseHeader("CONTENTPATH");//将后端重定向的地址取出来,使用win.location.href去实现重定向的要求
}
}
}); function updateCurrentUser(type){
//debugger;
jqxhr = $.ajax({
type: "GET",
async: true,
url: "../../center/updateCurrentUser?type="+type,
dataType: "json",
success: function(data){ },
error:function(err){ }
});
}
