java xml 多个根元素_java – 如何仅使用根元素解析XML

您正在寻找@XmlValue注释.

我的课

package forum13626828;

import javax.xml.bind.annotation.*;

@XmlRootElement(name = "element")

public class MyClass{

protected String elementValue;

@XmlValue

public String getElementValue() {

return elementValue;

}

public void setElementValue(String el) {

this.elementValue = el;

}

}

演示

package forum13626828;

import java.io.StringReader;

import javax.xml.bind.*;

public class Demo {

public static void main(String[] args) throws Exception {

JAXBContext jc = JAXBContext.newInstance(MyClass.class);

Unmarshaller unmarshaller = jc.createUnmarshaller();

StringReader xml = new StringReader("data");

MyClass myClass = (MyClass) unmarshaller.unmarshal(xml);

Marshaller marshaller = jc.createMarshaller();

marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

marshaller.marshal(myClass, System.out);

}

}
