java注解生成xml和包含CDATA问题

百度java生成xml，有一大推的文章，主要的生成方式一种使用Dom4J ,还有一种使用Jdk自带注解类！
下面主要整理我注解类的使用，（可以参考这篇文章Dom4J生成xml和包含CDATA问题）和xml中CDATA 问题的解决方法！
1:要生成的xml原始文件！

 
<item> 
  <id>35399645973id>   
  <title> title>  
 <category>保湿>洗护]]>category>
  <url> url> 
  <url_wap> url_wap>   
  <price>310price>   
  <promotion_price>93.8promotion_price> 
<wap_price>85wap_price> 
<sub_item_ids>
        <sub_item_id>35399645973_1sub_item_id>
        <sub_item_id>35399645973_2sub_item_id>
        <sub_item_id>35399645973_3sub_item_id>
        ……
sub_item_ids>
  <detail> detail> 
  <status>1<status>
    <pic_main> 
    <img>  
      <url> url> 
      <size>400x400size> 
    img> 
  pic_main> 
  <pic_extra> 
    <img> 
      <url> url> 
      <size>400x400size>  
    img>   
    <img> 
      <url> url> 
      <size>400x400size>  
    img>   
  pic_extra >   
item> 

2：xml对应的model类！
(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 subItemIds;//sub_item_ids

    @XmlElement
    private String detail;//detail

    @XmlElement
    private String status;//status


    @XmlElementWrapper(name="pic_main")
    @XmlElement(name="img")
    private List mainImg;//pic_main

    @XmlElementWrapper(name="pic_extra")
    @XmlElement(name="img")
    private List 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 subItemIds) {
        this.subItemIds = subItemIds;
    }

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

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

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

    public void setExtraImg(List 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：生成过程，已经CDATA问题处理！

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 list = new ArrayList();
        list.add("11_11_11");
        list.add("22_22_22");
        list.add("33_33_33");
        List imgList = new ArrayList();
        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("电视>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 这里面你标注需CDATA 的字段！

上面的这个例子可以直接拷贝运行，网上还一些其他的方法生成xml和CDATA，如果你有好的方法，欢迎分享给我，谢谢！
