dom4j java对象和xml互相转化

本文主要是介绍dom4j java对象和xml互相转化，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

首先导入dom4j（maven）<dependency><groupId>dom4j</groupId><artifactId>dom4j</artifactId><version>1.6.1</version>
</dependency>代码测试实体BankDatapublic class BankData {
private String id;// 主键
private String bizTime; // 时间
private String idcarrier; // 标识
private String organCode; // 组织编码
private String cardType; // 类型
public BankData() {
}/**
* 
* @param id
* @param bizTime
* @param idcarrier
* @param organCode
* @param cardType
*/
public BankData(String id, String bizTime, String idcarrier,
String organCode, String cardType) {
super();
this.id = id;
this.bizTime = bizTime;
this.idcarrier = idcarrier;
this.organCode = organCode;
this.cardType = cardType;
}public String getId() {
return id;
}public void setId(String id) {
this.id = id;
}public String getBizTime() {
return bizTime;
}public void setBizTime(String time) {
this.bizTime=time;
}public String getIdcarrier() {
return idcarrier;
}public void setIdcarrier(String idcarrier) {
this.idcarrier = idcarrier;
}public String getOrganCode() {
return organCode;
}public void setOrganCode(String organCode) {
this.organCode = organCode;
}public String getCardType() {
return cardType;
}public void setCardType(String cardType) {
this.cardType = cardType;
}public String toJSON() {
return "{\"id\":\"" + id + "\",\"bizTime\":\"" + bizTime
+ "\",\"idcarrier\":\"" + idcarrier + "\",\"organCode\":\""
+ organCode + "\",\"cardType\":\"" + cardType + "\"}";
}@Override
public String toString() {
return "BankData [id=" + id + ", bizTime=" + bizTime + ", idcarrier="
+ idcarrier + ", organCode=" + organCode + ", cardType="
+ cardType + "]";
