我正在使用这样的注释：
@WebServlet("/Document/*")
并使用sendRedirect
response.sendRedirect("Document/manpreet121FECF23A-D4D2-E411-BEC4-FCDD55FFFFFF");
我在一个看起来像这样的servlet中这样做：
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
String file = request.getParameter("nameoffile");
System.out.println(file);
String completefileName = file + request.getParameter("select1");
System.out.println(completefileName);
String emailid = request.getParameter("mailofmod");
System.out.println(emailid );
String ConcatUrl = Authentication.CreateFile(emailid, completefileName);
System.out.println("url " + ConcatUrl);
//String a = "SDJGR4WNVFKN";
String FinalURL = "Document/" + ConcatUrl;
System.out.println(FinalURL);
String path = request.getContextPath();
System.out.println("path " + path);
System.out.println("before redirect"+ path +"/" + FinalURL );
response.sendRedirect( path +"/" + FinalURL);
}
}
然而，它不起作用，我得到一个例外：
javax.servlet.ServletException: AS-WEB-CORE-00089
我该如何解决这个问题？
javax.servlet.ServletException: AS-WEB-CORE-00089

答案 0 :(得分：1)
使用sendRedirect时，您会向客户端（通常是浏览器）发送一个响应，其中包含应获取的URL。如果URL没有主机部分，则假定使用相同的主机，如果它不以/开头，则会将其添加到当前页面的URL中。
在您的情况下，您应该尝试在网址前加/（除非您有强的理由不这样做）在上下文路径前面加上：
contextPath = request.getContextPath();
response.sendRedirect(contextPath + "/Document/manpreet121FECF23A-D4D2-E411-BEC4-FCDD55FFFFFF");
如果仍无效，请直接在浏览器的地址栏中输入网址：
http://host.do.main/appname/Document/manpreet121FECF23A-D4D2-E411-BEC4-FCDD55FFFFFF"
并确保它有效。
如果有效，但重定向仍无效，请使用wireshark等工具监视发送给客户的实际响应，并在编辑中报告您的问题。
堆栈跟踪显示问题实际上完全不同（我仍然将上述答案作为参考）。根据它，您应该在Document.java方法的doGet第35行调用forward，其中servlet尝试转发给自己。这导致了一个无限循环，似乎被servlet容器检测为一个过于嵌套的请求调度。
