百度java生成xml，有一大推的文章，主要的生成方式一種使用Dom4J ,還有一種使用Jdk自帶註解類！
下麵主要整理我註解類的使用，（可以參考這篇文章Dom4J生成xml和包含CDATA問題）和xml中CDATA 問題的解決方法！
1:要生成的xml原始文件！

<?xml version="1.0" encoding="utf-8"?>

2：xml對應的model類！
(1):FanLiProductInofMsg.java

import java.util.List;

import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlElementWrapper;
import javax.xml.bind.annotation.XmlRootElement;

/**
 * 
 * @author aflyun
 * @date 2016.06.12
 *
 */
@XmlRootElement(name="item")
public class FanLiProductInofMsg {

    @XmlAttribute
    private String version;
    
    @XmlElement
    private String id;
    
    @XmlElement
    private String title;
    
    @XmlElement
    private String category;
    
    @XmlElement
    private String url;//Pc商品的url
    
    @XmlElement(name="url_wap")
    private String urlWap;//Wap商品的url  url_wap
    
    @XmlElement
    private String price;
    
    @XmlElement(name="promotion_price")
    private String promotionPrice;//promotion_price
    
    @XmlElement(name="wap_price")
    private String wapPrice;//wap_price
    
    @XmlElementWrapper(name="sub_item_ids")
    @XmlElement(name="sub_item_id")
    private List<String> subItemIds;//sub_item_ids
    
    @XmlElement
    private String detail;//detail
    
    @XmlElement
    private String status;//status
    
    
    @XmlElementWrapper(name="pic_main")
    @XmlElement(name="img")
    private List<Img> mainImg;//pic_main

    @XmlElementWrapper(name="pic_extra")
    @XmlElement(name="img")
    private List<Img> extraImg;//pic_extra

    
    public void setVersion(String version) {
        this.version = version;
    }

    public void setId(String id) {
        this.id = id;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public void setCategory(String category) {
        this.category = category;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    public void setUrlWap(String urlWap) {
        this.urlWap = urlWap;
    }

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

    public void setPromotionPrice(String promotionPrice) {
        this.promotionPrice = promotionPrice;
    }

    public void setWapPrice(String wapPrice) {
        this.wapPrice = wapPrice;
    }

    public void setSubItemIds(List<String> subItemIds) {
        this.subItemIds = subItemIds;
    }

    public void setDetail(String detail) {
        this.detail = detail;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    public void setMainImg(List<Img> mainImg) {
        this.mainImg = mainImg;
    }

    public void setExtraImg(List<Img> extraImg) {
        this.extraImg = extraImg;
    }

}

(2):Img .java

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
/**
 * 
 * @author aflyun
 * @date 2016.06.12
 *
 */
@XmlRootElement
public class Img {
    
    @XmlElement(name="url")
    private String url;
    
    @XmlElement(name="size")
    private String size;

    public void setUrl(String url) {
        this.url = url;
    }

    public void setSize(String size) {
        this.size = size;
    }
    
    
}

3：生成過程，已經CDATA問題處理！

package com.dufy.test.xml;


import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileWriter;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.List;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.transform.sax.SAXResult;

import org.apache.xml.serialize.OutputFormat;
import org.apache.xml.serialize.XMLSerializer;
import org.junit.Test;

import com.kuyu.b2b2c.product.fanli.vo.FanLiProductInofMsg;
import com.kuyu.b2b2c.product.fanli.vo.Img;

public class JuintXmlTest {

    private static Marshaller marshal;
    
    @Test
    public void testXml() throws Exception {
        List<String> list = new ArrayList<String>();
        list.add("11_11_11");
        list.add("22_22_22");
        list.add("33_33_33");
        List<Img> imgList = new ArrayList<Img>();
        Img img = null;
        for (int i = 0; i < 2; i++) {
            img = new Img();
            img.setUrl("-" + i + "-");
            img.setSize("40×40");
            imgList.add(img);
        }
        
        FanLiProductInofMsg fps = new FanLiProductInofMsg();
        fps.setVersion("1.0");
        fps.setId("110");
        fps.setTitle("4K 高清");
        fps.setCategory("電視>4K>高清");
        fps.setUrl("http://baidu.com");
        fps.setUrlWap("http://baidu.wap.com");
        fps.setPrice("100");
        fps.setPromotionPrice("111");
        fps.setWapPrice("113");
        fps.setSubItemIds(list);
        fps.setDetail("wwwwwwwwwwwwwwwwwwwwwww");
        fps.setStatus("1");
        fps.setMainImg(imgList);
        fps.setExtraImg(imgList);
        
         PrintWriter pw = new PrintWriter(new File("D:/test.xml"));
         String ojbectToXmlWithCDATA = ojbectToXmlWithCDATA(FanLiProductInofMsg.class, fps);
         System.out.println(ojbectToXmlWithCDATA);
         pw.println(ojbectToXmlWithCDATA);
         pw.close();
        
        
        
    }
     public static String ojbectToXmlWithCDATA(Class clazz, Object obj) throws Exception {  
      
            JAXBContext context = JAXBContext.newInstance(clazz);  
            // configure an OutputFormat to handle CDATA
            OutputFormat of = new OutputFormat();
            of.setCDataElements(
                  new String[] { "^title", //  
                                 "^category",
                                 "^url",
                                 "^url_wap",
                                 "^detail"
                                 }); //  

            // set any other options you'd like
            of.setPreserveSpace(true);
            of.setIndenting(true);
            // create the serializer
            ByteArrayOutputStream op = new ByteArrayOutputStream();  
            XMLSerializer serializer = new XMLSerializer(op, of);  
            SAXResult result = new SAXResult(serializer.asContentHandler());  
            Marshaller mar = context.createMarshaller(); 
            mar.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);  
            mar.marshal(obj, result);  
            
            return op.toString("utf-8");  
        }  

}

setCDataElements 這裡面你標註需CDATA 的欄位！

上面的這個例子可以直接拷貝運行，網上還一些其他的方法生成xml和CDATA，如果你有好的方法，歡迎分享給我，謝謝！
