The following editor will bring you an article about ajax request background in javawebservlet(example). The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor and take a look.

No more nonsense, just go to the code

public class DZFP_jdbc extends HttpServlet{
  private static final long serialVersionUID = 1L;

  public static Connection conn; 
  public static ResultSet rs = null ;  
  public static PreparedStatement ps = null ;
  private static String url = "jdbc:oracle:thin:@192.168.100.11:1111:CRM";
  private static String name = "name";
  private static String pwd = "pwd";

  protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    /*PreparedStatement ps;
    ResultSet rs = null;*/
    response.setCharacterEncoding("utf-8");
    request.setCharacterEncoding("utf-8");
    response.setHeader("content-type", "text/html;charset=UTF-8");

    PrintWriter out = response.getWriter();

    ***********

    out.print("{\"errorno\":[{\"list\":error}]}");
  }
}


$.ajax({ 
  type: "post", 
  url: "DZFP_jdbc", 
  dataType: "text", 

    data : {
      taxcode : taxcode,
      mobilenum : mobilenum
  },
  timeout : 50000,

    success: function (data) { 
  var jsonobjs = eval("(" + data + ")");
  var list = jsonobjs.errorno[0].list;


    }, 
  error: function() {
      alert("网络异常，请稍后重试");

  } 
});

<servlet>
