Apache CXF Spring SOAP Handler example

1. 環境說明

jdk 1.6.0-29

apache cxf 2.7.7

2. 新建web project，並添加apache cxf/lib目錄下所需jar，軟件目錄如下：

3. 程序代碼

Book.java

package com.unei.bean;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "Book")

	private int bookId;
	private String bookISBNnumber;
	private String bookName;
	private double price;
	private String author;

	public double getPrice() {
		return price;
	}

	public void setPrice(double price) {
		this.price = price;
	}

	public int getBookId() {
		return bookId;
	}

	public void setBookId(int bookId) {
		this.bookId = bookId;
	}

	public String getBookISBNnumber() {
