尽量少使用jaxb 进行xml与对象互换

尽量少使用jaxb 进行xml与对象互换

问题不少，这个好处在于方便，不用管他们之间的顺序。

 

xjc 命令 xjc aa.xsd -p com.aa -d work -b ff.xml

 

<jaxb:bindings

           xmlns:xsd="http://www.w3.org/2001/XMLSchema"

           xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"

           jaxb:extensionBindingPrefixes="inheritance"

           version="2.1">

  <jaxb:bindings

       schemaLocation="c:/a.xsd"

        node="/xsd:schema/xsd:element[@name='root_tagname']"

       <jaxb:class name="RootClassName" />

</jaxb:bingdings>

</jaxb:bindings>

 

write:

JAXBContext context = JAXBContent.newInstance(bean.getClass().getPackage().getName),Thread.currentThread().getContextClassLoader());

Marshaller marshaller = context.createMarshaller();

marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT,true);

marshaller.setProperty(Marshaller.JAXB_ENCODING,"UTF-8");

marshaller.setProperty(Marshaller.JAXB_FRAGMENT,false);

marshaller.marshal(bean,new File(filePath));

 

 

============================

read:

JAXBContext context = JAXBContent.newInstance(bean.getClass().getPackage().getName),Thread.currentThread().getContextClassLoader());

Unmarshaller unmarshaller = context.createUnmarshaller();

Object obj = unmarshaller.unmarshal(new File(filePath));

 

对于生成的JAXBElement对象实际过程中可将此对象替换为具体的类型的对象(String,Long,Boolean等)方便界面编辑保存。
