0x1：前言
前面搭建struts就不说了，大家都能成功完成。
0x2：Model
这里我们需要一个Model类来接收
<span style="font-size:10px;font-weight: normal;">package com.model;
public class BlogContent {
private int id;
private String title;
private String content;
public BlogContent(int id, String title, String content) {
super();
this.id = id;
this.title = title;
this.content = content;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
}</span><span style="color:#ff6666;font-size:18px;">
</span>

0x3：Action处理control
首先创建一个Action类，用来处理我们的请求。由于是测试，写的代码比较乱，大家将就看下。
package com.wzw;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts2.ServletActionContext;
import com.model.BlogContent;
import com.opensymphony.xwork2.ActionSupport;
import com.wzw.db.dbUtil;
public class BlogContentAction extends ActionSupport{
/**
*
*/
private static final long serialVersionUID = 7223376836405887303L;
@Override
public String execute() throws Exception {
// TODO 自动生成的方法存根
List<BlogContent> BlogContentlist=new ArrayList<BlogContent>();
String sql="select * from content";
dbUtil dbutil=new dbUtil();
Connection con=dbutil.getCon();
PreparedStatement pstmt= con.prepareStatement(sql);
ResultSet rs=pstmt.executeQuery();
while(rs.next())
{
int id=rs.getInt("id");
String title=rs.getString("title");
String content=rs.getString("content");
BlogContent temp=new BlogContent(id,title,content);
BlogContentlist.add(temp);
}
HttpServletRequest request = ServletActionContext.getRequest();
request.setAttribute("bloglist", BlogContentlist);
return SUCCESS;
}
}
PS:由于我之前用的这张表，字段分别是id主键，title 和content，用来测试。
0x4 映射
配置struts.xml文件。增加我们的映射。
<action name="BlogContent" class="com.wzw.BlogContentAction" >
<result name="success">/1.jsp</result>
<interceptor-ref name="defaultStack"></interceptor-ref>
</action>
访问以后跳转到1.jsp上去。
0x5 显示层 View
编写1.jsp来遍历我们request中存放的数据，代码如下
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<s:iterator value="#request.bloglist" id="mycontent" status="status">
<s:property value="#mycontent.id"/><br>
<s:property value="#mycontent.title"/><br>
<s:property value="#mycontent.content"/><br><hr>
</s:iterator>
</body>
</html>
0x6 result
访问我们的映射地址
http://localhost:8080/struts//BlogContent
结果如下
1
这是测试标题1
这是测试标题内容1。
2
Nothing is as sweet as you
Nothing is as sweet as you.....
