Spring框架，如何返回数据给视图(jsp文件)

第一步 准备返回给视图的数据

package com.cwebs.samples;  

import java.util.LinkedHashMap;
import java.util.List;
import java.util.Map;  

import javax.portlet.ActionResponse;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;  

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.portlet.ModelAndView;  

import com.cwebs.common.CMySQL;
import com.cwebs.common.ConnectionInfo;  

@Controller
@RequestMapping("VIEW")
public class QueryBySQLViewController {
    public ConnectionInfo ci = new ConnectionInfo(
            "jdbc:mysql://localhost:3366/test", "root", "root");      

    @RequestMapping
    public ModelAndView renderEditView(RenderRequest request,
            RenderResponse response) throws Exception {
        List<Map<String,String>> list=null;
        try {
            //step1:test open&close
            CMySQL db = new CMySQL(ci.connStr, ci.usr, ci.pwd);  

            //step2:test query with return
            list=db.executeQuery("select * from babywatch");
            db.testResult(list);          

        }catch(Exception ex)
        {
            ex.printStackTrace();
        }  

        final Map<String, Object> model = new LinkedHashMap<String, Object>();
        model.put("resultList", list);
        model.put("title", "测试表格");  

        return new ModelAndView("SQLQueryResult", model);
    }
}

　　第二步 在视图中显示

<%@page contentType="text/html;charset=utf-8" pageEncoding="utf-8"%>
<%@ include file="/WEB-INF/jsp/include.jsp" %>  

<!-- View Mode -->  

<h2>${title}</h2>  

<c:choose>
    <c:when test="${empty resultList}">
        <p>没有记录</p>
    </c:when>
    <c:otherwise>
        <table>
         <tr>
          <th>ID</th><th>名字</th><th>发布日期</th>
         </tr>
        <c:forEach var="result" items="${resultList}">
         <tr>
          <td>${result.BABYWATCH_ID}</td>
          <td>${result.BABYWATCH_NAME}</td>
          <td>${result.BABYWATCH_PUBLISHDATE}</td>
         </tr>
        </c:forEach>
        </table>
    </c:otherwise>
</c:choose>  

<h2>Portlet URLs</h2>
<ul>
    <li><a href="<portlet:renderURL portletMode="view" />">View Mode</a>
    <li><a href="<portlet:renderURL portletMode="edit" />">Edit Mode</a>
    <li><a href="<portlet:renderURL portletMode="help" />">Help Mode</a>
    <li><a href="<portlet:renderURL windowState="normal" />">Normal State</a>
    <li><a href="<portlet:renderURL windowState="maximized" />">Maximized State</a>
    <li><a href="<portlet:renderURL windowState="minimized" />">Minimized State</a>
</ul>

　　上例在视图中显示了一个简单的表格。
