在Struts 2中从JSP调用Java方法 [英] Calling Java method from JSP in Struts 2

问题描述

我想调用Java方法，该方法将向我返回数组列表，并且希望将该数组列表添加到JSP的下拉列表中.当用户从下拉列表中选择一个值时，该值将存储在变量类型中

I want to call Java method which returns me the array list and I want to add that array list to the drop-down list in JSP. When user select one value from the drop-down list that value is stored in the variable type

<form action="Config.action" method="post">
<table width="600" height="34" align="center" border="1" bgcolor="#CCCCCC"><br>
<%     
    Config c = new Config();
    ArrayList<String> names = c.populate();
    out.print("<table>  <tr><select>");

    for (String s : names) 
    {
        out.print("<option value="+s+">"+s+"</option>");
    }    
%>    
</select></table>

推荐答案

使用动作属性获取/设置名称

Use action properties to get/set the names

private String name;
//getter and setter

public ArrayList<String> getNames(){
  Config c = new Config();
  return c.populate();
}

JSP:

<form action="Config.action" method="post">
<table width="600" height="34" align="center" border="1" bgcolor="#CCCCCC"><br>
<s:select name="name" list="names"/>
</table>
</form>
