我在我的 java 类 DetailsForm 中设置 planValue 的值。我需要在 jsp 中获取该属性值。我将如何得到它？我在 jsp 中使用与 java 中的 planValue 相同的名称。

谢谢

使用类似这样的 Servlet 代码：

protected void doGet(HttpServletRequest request,
                HttpServletResponse response) throws ServletException, IOException         {
        performTask(request, response);
    }

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

public void performTask(HttpServletRequest request,
        HttpServletResponse response) throws ServletException, IOException {               //create your object
            DetailsForm detailsForm = new DetailsForm();
            //set planValue
            detailsForm.setPlanValue("some plan value");
            //set your object as attribute and use forward
    request.setAttribute("detailsForm", detailsForm);
            //relative path to your JSP
    request.getRequestDispatcher("/pages/some.jsp").forward(request,
            response);

}

还有你的 some.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<html>
<head>
<title>
Some JSP
</title>
<head>
<body>
${detailsForm.plainValue}
</body>
</html>

并且您需要在 DetailsForm 类中为 plainValue 提供 getter 方法。
