在jsp页面中给List赋值
MemberStruts

Java code

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;    }}

MemberInfoDao

Java code

package com.iconfluence.dao;import java.sql.Connection;import java.sql.PreparedStatement;import java.sql.ResultSet;import java.sql.Statement;import java.util.ArrayList;import java.util.List;import src.Common;import com.iconfluence.entity.MemberInfo;    public void setList(String ssql) throws Exception {        list = new ArrayList<MemberInfo>();        Connection conn = ConnectionUtils.getConnection();        Statement stmt = null;        ResultSet rs = null;        try {            stmt = conn.createStatement();            rs = stmt.executeQuery(ssql);            while (rs.next()) {                MemberInfo minfo = new MemberInfo();                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 {            if (rs != null){                rs.close();            }            if(stmt != null){                stmt.close();            }            if(conn != null){                conn.close();            }        }    }        public List<MemberInfo> getList(){        return list;    }

MemberInfo

Java code

/** *  */package com.iconfluence.entity;/** * @author Jiessie * */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;    }    }

XML code

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"    "http://struts.apache.org/dtds/struts-2.0.dtd">    <struts>    <package name="com.iconfluence.struts"  extends="struts-default">        <action name="he" class="com.iconfluence.struts.MemberStruts">            <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?

[解决办法]
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


[解决办法]
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;
}
}
[解决办法]
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

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
