spring-mvc ajax请求未显示重定向页面
在我的Spring MVC应用程序中,我想使用AJAX
index.jsp
在final.jsp
页面之间重定向我的页面。但是,当我单击Redirect
Page应用程序中的按钮时,未显示重定向页面(final.jsp)。我已经使用Java代码System.out.println("inside
/redirect");并System.out.println("inside
/finalPage");在Java代码内部检查了是否在服务器上接收到AJAX GET请求,并且仅inside
/redirect在打印该消息,这意味着/finalPage
未在调用AJAX
GET请求。而且,我的浏览器的控制台没有显示任何错误。因此,请告诉我们,问题可能出在哪里,问题出在哪里?我在下面发布了完整的代码:
package com.tutorialspoint;import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class WebController {
@RequestMapping(value = "/index", method = RequestMethod.GET)
public String index() {
return "index";
}
@RequestMapping(value = "/redirect", method = RequestMethod.GET)
public String redirect() {
System.out.println("inside /redirect");
return "redirect:/finalPage";
}
@RequestMapping(value = "/finalPage", method = RequestMethod.GET)
public String finalPage() {
System.out.println("inside /finalPage");
return "final";
}
}

回答:
您的浏览器未遵循重定向,因为您使用的是Ajax来访问控制器的重定向方法。您有两种选择:
完全不要使用ajax,让您的浏览器自然地响应重定向状态。
function redFun() {
window.location = "/HelloWeb/redirect";
}
查找对XmlHttpRequest的HTTP 302响应,并将window.location更改为响应中Location头的值:
function redFun() {
$.ajax({
type: "GET",
url: "/HelloWeb/redirect"
}).fail(function (jqXHR, status, err) {
if (jqXHR.status === 302) {
window.location = jqXHR.getResponseHeader('Location');
}
});
}
