输出为：

<?xml version="1.0" encoding="GBK" standalone="yes"?>
<personInfo>
    <Name>wangning</Name>
    <Gender>1</Gender>
    <Horoscopy>20180509</Horoscopy>
    <Territory>beijing</Territory>
    <CertType>sfz</CertType>
    <CertId>123456780987654</CertId>
</personInfo>


    <Name>wangning</Name>
    <Gender>1</Gender>
    <Horoscopy>20180509</Horoscopy>
    <Territory>beijing</Territory>
    <CertType>sfz</CertType>
    <CertId>123456780987654</CertId>

另外注意实体类中的字段需要使用

@XmlRootElement进行标注生成xml的节点

实体类：

import java.util.Arrays;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

/**

 * @author fdwdz
 *
 */
@XmlAccessorType(value=XmlAccessType.FIELD) 
@XmlRootElement
public class PersonInfo {
	/**
	 * 主索引UID
	 */
	@XmlElement
	private String UID;
	/**
	 * 姓名、称呼
	 */
	@XmlElement
	private String Name;
	/**
	 * 性别
	 */
	@XmlElement
	private String Gender;
	/**
	 * 出生日期
	 */
	@XmlElement
	private String Horoscopy;
	/**
	 * 出生地省级行政区
	 */
	@XmlElement
	private String Territory;
	/**
	 * 出生地语言标识
	 */
	@XmlElement
	private String Idiom;
	/**

	@XmlElement

	/**

	@XmlElement

	/**

	@XmlElement

	/**

	@XmlElement
	private String CertType;
	/**
