Servlet接收数组

要在ajax什么加个$.ajaxSettings.traditional=true;才可以传数组

  var goods=["11","11"];
    $.ajaxSettings.traditional=true;
    $.post("postObject",{goods:goods},function (data) {

    });

Servlet通过getParameterValues方法接收

@WebServlet(name = "PostObjectServlet",urlPatterns = {"/postObject"})
public class PostObjectServlet extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String[] str=request.getParameterValues("goods");
        System.out.println(str);
        System.out.println(str.length);
        for(String string: str){
            System.out.println(string);
        }
    }

Servlet接收对象

  var foods=[{name:"cool",age:1},{name:"cool",age:1}]

    $.ajaxSettings.traditional=true;
    $.post("postObject",{foods:foods},function (data) {

    });

暂时没有实现接收
