双硬盘下Ubuntu 16.04与Win10双系统的安装之前写过一个双系统安装过程，今天再次整理的原因是想重点强调双硬盘的区别。标红的一定要注意看，那就是我自己一步一步踏出来的坑啊... 基础步骤就不再重复，重点讲区别，需要看详细步骤的童鞋（或者你只有一个硬盘）请看我上一篇博客https://blog.csdn.net/weixin_40308540/article/details/80157444 区别：双硬盘和单硬盘的区别是什么呢？... 阅读详情

晕，怎么就发出去了？？

Action改为：
Collection col = user.userList();
httpServletRequest.setAttribute("list", col);
return actionMapping.findForward("success");

jsp：

<logic:iterate id="userListAction" name="list" scope="request" type="com.jansky.weboa.entity.userActionForm">
<tr>
<td> <bean:write name="userListAction" property="user_id"/></td>
<td> <bean:write name="userListAction" property="user_name"/></td>
<td> <bean:write name="userListAction" property="user_pwd"/></td>
</tr>
</logic:iterate>

Action如下：
package com.jansky.weboa.Action;

import com.jansky.weboa.entity.*;
import org.apache.struts.action.*;
import javax.servlet.http.*;
import java.sql.Connection;
import java.sql.SQLException;
import java.util.Collection;
import com.jansky.weboa.db.connPool;
import com.jansky.weboa.db.userDAO;
public class userListAction extends Action {
private connPool pool;
public ActionForward execute(ActionMapping actionMapping, ActionForm actionForm, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) {
// userActionForm userActionForm = (userActionForm) actionForm;
// throw new java.lang.UnsupportedOperationException("Method perform() not yet implemented.");
Connection con=null;
con = pool.connPool();
userDAO user = new userDAO(con);
Collection col = user.userList();
httpServletRequest.setAttribute("userActionForm", col);
return actionMapping.findForward("success");

}

}
ActionForm如下:

package com.jansky.weboa.entity;
/**
*Title:实体建模
*Description：定义表user中列项的属性
*Time:2004-9-15
*Company:jansky
*Author:黄晓华
*version1.0
*/
import org.apache.struts.action.*;
import javax.servlet.http.*;
import java.util.ArrayList;
public class userActionForm extends ActionForm {
private String user_id;
private String user_name;
private String user_pwd;
public String getUser_id() {
return user_id;
}
public void setUser_id(String user_id) {
this.user_id = user_id;
}
public String getUser_name() {
return user_name;
}
public void setUser_name(String user_name) {
this.user_name = user_name;
}
public String getUser_pwd() {
return user_pwd;
}
public void setUser_pwd(String user_pwd) {
this.user_pwd = user_pwd;
}
public ActionErrors validate(ActionMapping actionMapping, HttpServletRequest httpServletRequest) {
/**@todo: finish this method, this is just the skeleton.*/
return null;
}
public void reset(ActionMapping actionMapping, HttpServletRequest httpServletRequest) {
}
}

你的ACTION中的VO传回的值要与你的JSP页面中的LOGIC中的NAME值一样，你才能正确的取到值
