如何在异步Servlet中重定向？

Question

According to this document , I understand a Request could be dispatch forward to another servlet in one Asynchronous Servlet which also makes container to call complete() and trigger another Servlet or JSP automatically.

But, what if I want to redirect the page under async Servlet? Should I call complete() and response.redirect("") both? do we have any example of redirection?

Thanks.

在这种情况下，您可以执行以下操作：使用response.getWriter.write（jsonObject）向客户端（浏览器）提供特定的json响应，并在JavaScript中编写用于更改位置的代码，即location.assign（“ / newPage”）。
