实体对象转化xml

将实体对象User转换成Xml格式。

实体类User

package com.example.webservice.demo.service.server;import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;/*** &＃64;author LiHaitao* &＃64;description User:* &＃64;date 2020/1/6 17:51**/&＃64;XmlRootElement(name &＃61; "user")
&＃64;XmlType(propOrder &＃61; { "name", "age" }) // 定义xml节点的顺序,属性必须在这
public class User {public User(){}public User(String name, String age) {this.name &＃61; name;this.age &＃61; age;}private String name;private String age;&＃64;XmlElement(name &＃61; "name")public String getName() {return name;}public void setName(String name) {this.name &＃61; name;}&＃64;XmlElement(name &＃61; "age")public String getAge() {return age;}public void setAge(String age) {this.age &＃61; age;}
}

工具类

package com.example.webservice.demo.service.server;import lombok.extern.slf4j.Slf4j;import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;
import java.io.StringWriter;/**
* &＃64;Description:
* &＃64;Author: Lihaitao
* &＃64;Date: 2020/1/7 17:22
* &＃64;UpdateUser:
* &＃64;UpdateRemark:
*/
&＃64;Slf4j
public class JaxResultUtil {private static JAXBContext context &＃61; null;private static Marshaller marshaller &＃61; null;static {try {context &＃61; JAXBContext.newInstance(User.class);marshaller &＃61; context.createMarshaller();marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");} catch (JAXBException e) {log.error("JaxResultUtil init exception", e);}}public static <T> String objToXmlString(T obj) throws JAXBException {StringWriter writer &＃61; new StringWriter();marshaller.marshal(obj, writer);return writer.toString();}}


使用

User lihaitao &＃61;new User("lihaitao","18");System.out.println(JaxResultUtil.objToXmlString(lihaitao));
