MemberStruts

package com.iconfluence.struts;

public class MemberStruts extends ActionSupport{

MemberInfoDao

package com.iconfluence.dao;

import java.sql.Connection;

			rs = stmt.executeQuery(ssql);
			while (rs.next()) {

				minfo.setId(rs.getInt("id"));
				minfo.setMembername(rs.getString("membername"));
				minfo.setJoindate(Common.formatDate(rs.getDate("joindate"), "yyyy-MM-dd"));
				minfo.setSurplus(rs.getFloat("surplus"));
				list.add(minfo);
			}
		}finally {

				stmt.close();
			}
			if(conn != null){
				conn.close();

	}	
	public List<MemberInfo> getList(){
		return list;
	}

MemberInfo

/**

package com.iconfluence.entity;

/**

public class MemberInfo{
	
	private Integer id;
	private String membername;
	private String joindate;
	private float surplus;		
	
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}	
	public String getMembername() {
		return membername;
	}
	public void setMembername(String membername) {
		this.membername = membername;
	}
	public String getJoindate() {
		return joindate;
	}
	public void setJoindate(String joindate) {
		this.joindate = joindate;
	}
	public float getSurplus() {
		return surplus;
	}
	public void setSurplus(float surplus) {
		this.surplus = surplus;
	}	
}

    <package name="com.iconfluence.struts"  extends="struts-default">

            <result>consumequery.jsp</result>
        </action>
    </package>
</struts>

然后我想在提到到的consumequery.jsp页面中把member.getList()赋值给一个List对象应该怎么赋值?

自己顶下

放到form中或者Session中
JSP使用跌代标签获得
如果我说的你不懂请看书

package com.iconfluence.struts;

import com.iconfluence.dao.MemberInfoDao;
import com.opensymphony.xwork2.ActionSupport;

public class MemberStruts extends ActionSupport{

private MemberInfoDao member = new MemberInfoDao();

public MemberInfoDao getMember() {
return member;
}
public void setMember(MemberInfoDao member) {
this.member = member;
}
public String execute(){
String ssql = "select * from tb_memberinfo";
try {
member.setList(ssql);
} catch (Exception e) {
e.printStackTrace();
}
return SUCCESS;
}
}
改成:
package com.iconfluence.struts;

import com.iconfluence.dao.MemberInfoDao;
import com.opensymphony.xwork2.ActionSupport;

public class MemberStruts extends ActionSupport{

private MemberInfoDao member = new MemberInfoDao();
private List list = new ArrayList();

public MemberInfoDao getMember() {
return member;
}
public void setMember(MemberInfoDao member) {
this.member = member;
}
public List getList() {
return list;
}
public void setList(List list) {
this.list = list;
}
public String execute(){
String ssql = "select * from tb_memberinfo";
try {
list = member.setList(ssql);
} catch (Exception e) {
e.printStackTrace();
}
return SUCCESS;
}
}

把list放入session 或request中，然后再在consumequery.jsp中使用内置对象获得该list，不就可以了嘛

[/Quote]

我用的是struts 您说的是Servlet中的setAttribute方法

[sugar8763]

这有什么不同吗，struts中的action不也是servlet吗，都可以用setAttribute呀

[robyjeffding]

用struts也一样的啊，返回一个ActionForward对象，
里面不也是接收一个响应和请求的参数吗？(response和request)
只是你用mapping.findForward()时，一定要设为转发，此时
request.setAttribute("list",member.getList());
转发到相应页面，就可以提取list了

搞定了

<s:iterator value="member.list">
<tr>
<td><s:property value="getId()"/></td>
<td><s:property value="getMembername()"/></td>
<td><s:property value="getJoindate()"/></td>
<td><s:property value="getSurplus()"/></td>
<td><input /></td>
</tr>
</s:iterator>

真服了 这都不会
