我在这个论坛上寻找解决方案，但没有找到适合我的问题的解决方案。
我有一个非常简单的代码
一个jsp页面
<html>
<body>
<jsp:include page="/servletName"/>
</body>
</html>
和一个servlet
@WebServlet("/servletName")
public class reindirizzaController extends HttpServlet {
private static final long serialVersionUID = 1L;
public reindirizzaController() {
super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String redirectURL = "http://www.google.it";
response.sendRedirect(redirectURL);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
}
}
没有重定向。我被困在 jsp 页面中，没有收到任何错误。我还尝试在响应后添加 return;。
最佳答案
因为您是通过Include 调用servlet，所以它不会让您重定向。它只是忽略。
来自 include() 的文档
includes the content of a resource (servlet, JSP page, HTML file) in the response. In essence, this method enables programmatic server-side includes.
The ServletResponse object has its path elements and parameters remain unchanged from the caller's. The included servlet cannot change the response status code or set headers; any attempt to make a change is ignored.
