如何将Date request.getParameter转换为字符串？

Question

所以这是我的servlet代码。我试着将用户输入添加到mysql。 AddEventsServlet.java：

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub
    //doGet(request, response);
    String title = request.getParameter("title");
    String eventDesc= request.getParameter("eventDesc");
    <!--Here is my problem, it can't compile cuz Date StartTime and EndTime and Double budget is wrong -->

    Date StartTime= request.getParameter("StartTime");
    Date EndTime= request.getParameter("EndTime");

    Double Budget= request.getParameter("Budget");
}

我在某处看到request.getParameter仅用于String，那么如何将其转换为String？请帮助：）

Answer 1

这会将字符串转换为日期格式

String StartTimeStr = request.getParameter("StartTime");
String EndTimeStr = request.getParameter("EndTime");

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");

Date StartTime = dateFormat.parse(StartTimeStr);
Date EndTime = dateFormat.parse(EndTimeStr);
