使用JaxB解析类层次结构 [英] Parsing class hierarchy using JaxB
本文介绍了使用JaxB解析类层次结构的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有类层次结构
interface Intf {}
Class A implements Intf{}
Class B implements Intf{}
现在我在<$ c以上使用$ c> A类和 B类
用jpB的elp读取两个不同的XML文件。任何人都可以建议我如何配置和使用JaxB中的上述结构?
Now I am using above Class A
and Class B
to read two diffrent XML files with the elp of JaxB. Can any one suggest me how to configure and use structure like above in JaxB?
推荐答案
对于您的用例,界面不如果你想将 A
和 B
映射到不同的XML结构,你可以继续这样做,我下面将举例说明。
For your use case the interface doesn't factor in. If you want to map A
and B
to different XML structures you can go ahead and do so, I'll demonstrate below with an example.
JAVA模型
IntF
IntF
public interface IntF {
public String getFoo();
public void setFoo(String foo);
}
A
A
import javax.xml.bind.annotation.*;
@XmlRootElement
public class A implements IntF {
private String foo;
@Override
@XmlElement(name="renamed-foo")
public String getFoo() {
return foo;
}
@Override
public void setFoo(String foo) {
this.foo = foo;
}
}
B
B
import javax.xml.bind.annotation.*;
@XmlRootElement
public class B implements IntF {
private String foo;
@Override
@XmlAttribute
public String getFoo() {
return foo;
}
@Override
public void setFoo(String foo) {
this.foo = foo;
}
}
DEMO CODE
演示
Demo
import javax.xml.bind.*;
public class Demo {
public static void main(String[] args) throws Exception {
JAXBContext jc = JAXBContext.newInstance(A.class, B.class);
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
A a = new A();
a.setFoo("Hello World");
marshaller.marshal(a, System.out);
B b = new B();
b.setFoo("Hello World");
marshaller.marshal(b, System.out);
}
}
输出
Output
<?xml version="1.0" encoding="UTF-8"?>
<a>
<renamed-foo>Hello World</renamed-foo>
</a>
<?xml version="1.0" encoding="UTF-8"?>
<b foo="Hello World"/>
