action中没有执行execute()与prepare()方法
pagingaction.java
package com.action;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts2.interceptor.ServletRequestAware;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.Preparable;
import java.util.*;
public class pagingAction extends ActionSupport implements Preparable
{
private static int firstPage = 1; //第一页
public void setFirstPage(int firstPage)
{
this.firstPage = 1;
}
public int getFirstPage()
{
return firstPage;
}
@Override
public String execute() throws Exception
{
setFirstPage(int 3);
return "success";
}
@Override
public void prepare() throws Exception
{
setFirstPage(int 2);
}
}

</tr>
</table>
</s:form>
</body>
</html>
用的是eclipse 开发
然后直接运行paging.jsp页面 得到的:<s:property value="firstPage"/> 的值是空值
为什么 pagingaction.java 中的
@Override
public String execute() throws Exception
{
setFirstPage(int 3);
return "success";
}
@Override
public void prepare() throws Exception
{
setFirstPage(int 2);
}
这两段代码没有执行呢
