第一个struts2 程序

环境: tomact7/jdk1.6/eclipse Indigo

今天开始看<<Struts 2 Design and Programming: A Tutorial>> by Budi Kurniawan,

由于公司不能下载，只能使用struts-2.2.1了。当我把所有的jar包copy到lib目录下启动tomact时(使用tomact6),竞然报错，找了一下，是少了这个包: javassist-3.11.0.GA.jar,找了个，再启动，还是报错，原来是没有写spring listener，删除了struts2包里所有的spring相关的包和所有的plugin相关包，启动ok.
以下为本书46页的第一个struts2小程序，运行ok!

核心中有如下几个文件,
Product.java:

package business.action;
import java.io.Serializable;;

public class Product implements Serializable{
	private String productName;
	private String description;
	private String price;
	
	public String getProductName() {
		return productName;
	}
	public void setProductName(String productName) {
		this.productName = productName;
	}
	public String getDescription() {
		return description;
	}
	public void setDescription(String description) {
		this.description = description;
	}
	public String getPrice() {
		return price;
	}
	public void setPrice(String price) {
		this.price = price;
	}
	
	public String execute(){
		return "success";
	}
}

product.jsp:

<html>
<head>
<title>Add Product Form</title>
</head>
<body>
	<div id="global" align="center">
		<h3>add a product</h3>
		<form method="post" action="Product_save.action">
			<table>
			<tr>
				<td>Product Name:</td>
				<td><input type="text" name="productName"/></td>
			</tr>
			<tr>
				<td>Description:</td>
				<td><input type="text" name="description"/></td>
			</tr>
			<tr>
				<td>Price:</td>
				<td><input type="text" name="price"/></td>
			</tr>							
			<tr>
				<td><input type="reset"/></td>
				<td><input type="submit" value="Add Product"/></td>
			</tr>							
			</table>
		</form>
	</div>
</body>
</html>

details.jsp:

<html>
<head>
<title>Save Product</title>
</head>
<body>
	<div id="global" align="center">
		<h4>The product has been saved.</h4>
		<p>
		       <h5>Details:</h5>
			product Names :${productName}<br/>
			Description :${description}<br/>
			Price :${price}<br/> 
			
		</p>
	</div>
</body>
</html>

struts.xml:

	</package>
</struts>

无关jar包太多，文件有点大，不过，总算跑起来了。
