废话不多说，直接上代码

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");

  } 
});
