Spring Controller redirect to another page
提问by user1386375
Hey I got the following problem. This is the content of the jspx file:
嘿，我遇到了以下问题。这是jspx文件的内容：
function postSMTH() {
$.ajax({
type: "POST",
url: document.getElementById("urltxt").value,
data: parameters,
});
}
<input type="hidden" value="${pageContext.request.contextPath}/foo/foo2/foodat" name="urltxt" id="urltxt"/>
<div class="foodat"><a href="javascript:postSMTH();"><spring:message code="foo_foo2_foodat_text" text="FOODAT"/></a></div>
So if I push the submit button, the postSMTHfunction is called and the ajax object is paste to the Controller which look like this:
因此，如果我按下提交按钮，postSMTH则会调用该函数并将 ajax 对象粘贴到控制器，如下所示：
@Controller
@RequestMapping(value="/foo")
public class FooController {
..............
@RequestMapping(value="/foo2", method=RequestMethod.POST)
public String homePOST(HttpServletRequest request) {
........
}
@RequestMapping(value="/foo2", method=RequestMethod.GET)
public String homeGET(HttpServletRequest request) {
........
}
@RequestMapping(value="/foo2/foodat", method=RequestMethod.POST)
public String doTHAT(HttpServletRequest request) {
// check authorization
Map fooMap = request.getParameterMap();
// do something in the Database, depending on the paramMap
return "redirect:/foo/foo1";
}
}
Everything is working fine regarding the Database, but the Problem is, that the redirect at the end DOESN'T work. It just stays at the page foo2.
关于数据库一切正常，但问题是，最后的重定向不起作用。它只停留在 foo2 页面。
I'm new to Spring, maybe its a little mistake somewhere. I just cant make it out by myself.
我是 Spring 的新手，也许在某个地方有点错误。只是我自己弄不出来。
Would be nice if someone would have some hint. Thanks
如果有人有一些提示，那就太好了。谢谢

You are making asynchronous form submission using jquery ajax call. So, after your request is completed you need to change the document location using javascript. E.g., something like this:
您正在使用 jquery ajax 调用进行异步表单提交。因此，在您的请求完成后，您需要使用 javascript 更改文档位置。例如，这样的事情：
$.ajax({
type: "POST",
url: document.getElementById("urltxt").value,
data: parameters,
complete: function() {
window.location.replace(...);
}
});

It's not redirecting because you are submitting via ajax. You'll need to handle the redirect yourself. Perhaps this very popular question will help. How to manage a redirect request after a jQuery Ajax call
这不是重定向，因为您是通过 ajax 提交的。您需要自己处理重定向。也许这个非常受欢迎的问题会有所帮助。如何在 jQuery Ajax 调用后管理重定向请求
