目标：使用strust对数据库表格进行增删改查

需要的jar包依赖

由于重点在体现strust的使用，所以很多东西就用之前的，（例如之前的前端页面，帮助类，自定义标签）

a.实体类：

clz

package com.csf.entity;

public class Clz {
	private int cid;
	private String cname;
	private String cteacher;
	private String pic;
	public int getCid() {
		return cid;
	}
	public void setCid(int cid) {
		this.cid = cid;
	}
	public String getCname() {
		return cname;
	}
	public void setCname(String cname) {
		this.cname = cname;
	}
	public String getCteacher() {
		return cteacher;
	}
	public void setCteacher(String cteacher) {
		this.cteacher = cteacher;
	}
	public String getPic() {
		return pic;
	}
	public void setPic(String pic) {
		this.pic = pic;
	}
	public Clz() {
		// TODO Auto-generated constructor stub
	}
	public Clz(int cid, String cname, String cteacher, String pic) {
		super();
		this.cid = cid;
		this.cname = cname;
		this.cteacher = cteacher;
		this.pic = pic;
	}
	@Override
	public String toString() {
		return "Clz [cid=" + cid + ", cname=" + cname + ", cteacher=" + cteacher + ", pic=" + pic + "]";
	}
	
}

b.先写web层，根据需求写，这里继承baseDao (在上一篇博客中有，所以省略了)

package com.csf.web;

import com.csf.dao.ClzDao;
import com.csf.entity.Clz;
import com.zking.util.baseAction;
import com.zking.util.PageBean;

public class ClzAction extends baseAction{
	private Clz clz=new Clz();
	private ClzDao clzDao=new ClzDao();
	
	

	public String list() throws Exception {
	PageBean pageBean=new PageBean();
	pageBean.setRequest(req);
	this.result=this.clzDao.list(clz, pageBean);
	this.req.setAttribute("result", result);
	this.req.setAttribute("pageBean", pageBean);
		return LIST;
	}
	

	public String toEdit() throws Exception {
		int cid = clz.getCid();
		if(cid!=0) {
			this.result=this.clzDao.list(clz,null).get(0);
			this.req.setAttribute("result", result);
		}
		return TOEDIT;
	}
	

	public String add() throws Exception {
	this.clzDao.add(clz);
		return TOLIST;
	}
	
	
	public String del() throws Exception {
		this.clzDao.del(clz);
		return TOLIST;
	}
	
	
	public String edit() throws Exception {
		this.clzDao.edit(clz);
		return TOLIST;
	}
	
	
	@Override
	public Clz getModel() {
		// TODO Auto-generated method stub
		return clz;
	}

}

c.再配置到strust-sy.xml中：

		
		
			/clzList.jsp
			/clzEdit.jsp
			/clz_list
		

	

d.编写前端页面，clzList：

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>
<%@ taglib uri="http://jsp.veryedu.cn" prefix="z"%>	
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>	








.page-item input {
	padding: 0;
	width: 40px;
	height: 100%;
	text-align: center;
	margin: 0 6px;
}

.page-item input, .page-item b {
	line-height: 38px;
	float: left;
	font-weight: 400;
}

.page-item.go-input {
	margin: 0 10px;
}

${b.cid }
				
${b.cname}
				
${b.cteacher }

					修改
					删除
				
			
			
		
	
	
	

 clzEdit:

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>








id:

title:

cteacher:

展示数据页面：

 增加页面：

 修改页面：

 删除比较简单，不做演示

strust与mvc框架用法相似不同的在与配置文件和web层的方法使用
