如何使用JAXB构建映射XML结构的Java对象?
使用jaxb构建与xml结构相映射的java对象
如何利用jaxb框架构建java对象,以映射如下xml结构:
<speak><voice name="zh-cn-yunxineural">我是 <break time="1000ms"></break>张三 </voice><voice name="zh-cn-xiaoxiaoneural">他是 <break time="100ms"></break>李四 </voice></speak>
代码实现
基于提供的xml结构,可以设计以下java对象模型:
@data @xmlaccessortype(xmlaccesstype.field) @xmlrootelement(name = "voice") public class voicexbj { @xmlattribute private string name; @xmlmixed @xmlelementref(type = breakxbj.class) private list<object> content; } @data @xmlaccessortype(xmlaccesstype.field) @xmlrootelement(name = "break") public class breakxbj { @xmlattribute private string time; }</object>
在主类中,可以创建这些对象的实例并将其编组为一个表示整个xml结构的speakxbj对象:
voicexbj voice = new voicexbj(); voice.setname("yunxi"); breakxbj breakxbj = new breakxbj(); breakxbj.settime("1000ms"); list<object> breaklist = new arraylist(); breaklist.add("我是"); breaklist.add(breakxbj); breaklist.add("张三"); voice.setcontent(breaklist); list<voicexbj> voicelist = new arraylist(); voicelist.add(voice); voicexbj voice1 = new voicexbj(); voice1.setname("xiaomeng"); breakxbj breakxbj1 = new breakxbj(); breakxbj1.settime("100ms"); list<object> breaklist1 = new arraylist(); breaklist1.add("他是"); breaklist1.add(breakxbj1); breaklist1.add("李四"); voice1.setcontent(breaklist1); voicelist.add(voice1); speakxbj xbj = new speakxbj(); xbj.setvoice(voicelist); string xml = xmlutil.converttoxml(xbj);</object></voicexbj></object>
其中,xmlutil类提供了将对象转换为xml字符串的实用方法。
输出结果
最终,生成的xml字符串与原始结构完全一致:
<?xml version="1.0" encoding="GBK" standalone="yes"?><speak version="1.0" xmlns="http://www.w3.org/2001/10/synthesis" xmlns:mstts="http://www.w3.org/2001/mstts" xmlns:emo="http://www.w3.org/2009/10/emotionml" xml:lang="zh-CN"><voice name="Yunxi">我是 <break time="1000ms"></break>张三</voice><voice name="Xiaomeng">他是 <break time="100ms"></break>李四</voice></speak>
