项目为了进行xml与java bean的互转，参考了各位网友的推荐，最后选型为JAXB，闲暇之余整理了一下笔记。废话不多说，上代码
当然JDK至少是1.6的啊，好处是再不需要其他的包
这里构造一个persion对象，很简单，先来看第一个简单的例子，进入到JAXB的世界
Java代码
package cn.uyunsky.blog.xml.demo1;
import java.io.StringReader;
import java.io.StringWriter;
import java.util.Date;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;
import javax.xml.bind.Unmarshaller;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlRootElement;
/**
*
先来个简单的
*/
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class Persion {
private Integer userid;
private String username;
private Date birthday;
public Integer getUserid() {
return userid;
}
public void setUserid(Integer userid) {
this.userid = userid;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
@Override
public String toString() {
StringBuilder builder = new StringBuilder();
builder.append("Persion [userid=");
builder.append(userid);
builder.append(", username=");
builder.append(username);
builder.append(", birthday=");
builder.append(birthday);
builder.append("]");
return builder.toString();
}
public static void main(String[] args) {
try {
JAXBContext jaxbContext = JAXBContext.newInstance(Persion.class);
Persion persion = new Persion();
persion.setUserid(112);
persion.setUsername("就不告诉你");
persion.setBirthday(new Date());
Marshaller marshaller = jaxbContext.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
StringWriter writer = new StringWriter();
marshaller.marshal(persion, writer);
String xml = writer.getBuffer().toString();
System.out.println(xml);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
Object bean = unmarshaller.unmarshal(new StringReader(xml));
System.out.println(bean);
} catch (JAXBException e) {
e.printStackTrace();
}
}
}
执行结果
Xml代码
< xml version="1.0" encoding="UTF-8" standalone="yes" >
Persion [userid=112, username=就不告诉你, birthday=Wed Sep 28 11:06:29 CST 2011]
下来我们再深入些，看看其他情况下的处理，请看下节
