JAXB主要用来实现对象和XML之间的序列化和反序列化，关于JAXB的介绍就不多说了，网上一搜一大把，这里主要总结下基本使用方法和一些注意事项
首先定义两个示例类ClassA,ClassB,用于后续的示例演示
复制代码
package cn.lzrabbit;
public class ClassA {
private int classAId;
private String classAName;
private ClassB classB;
public int getClassAId() {
return classAId;
}
public void setClassAId(int classAId) {
this.classAId = classAId;
}
public String getClassAName() {
return classAName;
}
public void setClassAName(String classAName) {
this.classAName = classAName;
}
public ClassB getClassB() {
return classB;
}
public void setClassB(ClassB classB) {
this.classB = classB;
}
}
复制代码
package cn.lzrabbit;
public class ClassB {
private int classBId;
private String classBName;
public int getClassBId() {
return classBId;
}
public void setClassBId(int classBId) {
this.classBId = classBId;
}
public String getClassBName() {
return classBName;
}
public void setClassBName(String classBName) {
this.classBName = classBName;
}
}

用于序列化的XmlUtil
package cn.lzrabbit;
import java.io.StringReader;
import java.io.StringWriter;
import javax.xml.bind.*;
public class XmlUtil {
public static String toXML(Object obj) {
try {
JAXBContext context = JAXBContext.newInstance(obj.getClass());
Marshaller marshaller = context.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");// //编码格式
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);// 是否格式化生成的xml串
marshaller.setProperty(Marshaller.JAXB_FRAGMENT, false);// 是否省略xm头声明信息
StringWriter writer = new StringWriter();
marshaller.marshal(obj, writer);
return writer.toString();
} catch (Exception e) {
throw new RuntimeException(e);
}
}
