jaxb实现java对象与xml之间转换_JAXB实现xml与对象互相转换

不需要引入任何外部jar包，JAXB自jdk1.5就已被集成，jdk1.7已升级为JAXB2。

2.利用trang.jar自动生成对应的javabean，trang.jar下载地址：https://download.csdn.net/download/shenszy/10673076，生成的javabean需更改注解并修改package-info.java文件。也可手写javabean。修改后对象及package-info.java文件见下方代码：

Root.java

@XmlRootElement(name = "root")

@XmlAccessorType(XmlAccessType.NONE)

public class Root {

@XmlElement(name = "MsgHeader")

private MsgHeader MsgHeader;

@XmlElement(name = "MsgBody")

private MsgBody MsgBody;

//get,set省略……

}

MsgHeader.java

@XmlRootElement(name = "MsgHeader")

@XmlAccessorType(XmlAccessType.NONE)

public class MsgHeader {

@XmlElement(name = "SndDt")

private String sndDt;

@XmlElement(name = "MsgTp")

private String msgTp;

@XmlElement(name = "IssrId")

private String issrId;

@XmlElement(name = "Drctn")

private String drctn;

@XmlElement(name = "SignSN")

private String signSn;

@XmlElement(name = "NcrptnSN")

private String ncrptnSN;

@XmlElement(name = "DgtlEnvlp")

private String dgtlEnvlp;

//get,set省略……

}

MsgBody.java

@XmlRootElement(name = "MsgBody")

@XmlAccessorType(XmlAccessType.NONE)

public class MsgBody {

@XmlElement(name = "PyerInf")

private PyerInf pyerInf;//付款方信息

@XmlElement(name = "PyerTrxTrmNo")

private String pyerTrxTrmNo;//收付标识，1：付款方，2-收款方

@XmlElement(name = "PyeeInf")

private PyeeInf pyeeInf;//收款方信息

@XmlElement(name = "ResfdtInf")

private ResfdtInf resfdtInf;//备付金信息

@XmlElement(name = "TrxInf")

private TrxInf trxInf;//交易信息

@XmlElement(name = "OrdrInf")

private OrdrInf ordrInf;//订单信息

@XmlElement(name = "BatchId")

private String batchId;//交易批次号

@XmlElement(name = "TrxDevcInf")

private String trxDevcInf;//交易设备信息

//get,set省略……

}

PyerInf.java  ResfdtInf.java  TrxInf.java  OrdrInf.java注解与MsgHeader.java注解一样

PyeeInf.java

@XmlRootElement(name = "PyeeInf")

@XmlAccessorType(XmlAccessType.NONE)

public class PyeeInf {

@XmlElement(name = "PyeeAcctIssrId")

private String pyeeAcctIssrId;

@XmlElement(name = "PyeeAcctId")

private String pyeeAcctId;

@XmlElement(name = "PyeeAcctNm")

private String pyeeAcctNm;

@XmlElement(name = "PyeeAcctTp")

private ListpyeeAcctTp;//有多个同字段数据

@XmlElement(name = "PyerTrxTrmTp")

private String pyeeTrxTrmTp;

@XmlElement(name = "PyerTrxTrmNo")

private String pyeeTrxTrmNo;

//get,set省略……

}

package-info.java  对命名空间及前缀进行处理

@XmlSchema(

namespace = "urn:iso:std:iso:20022:tech:xsd:pacs.008.001.02",

elementFormDefault = XmlNsForm.QUALIFIED,

xmlns = {

@XmlNs(namespaceURI = "urn:iso:std:iso:20022:tech:xsd:pacs.008.001.02", prefix = "")

}

)

package com.example.webflux02.domain;

import javax.xml.bind.annotation.XmlNs;

import javax.xml.bind.annotation.XmlNsForm;

import javax.xml.bind.annotation.XmlSchema;

3.xml与对象互相转换

xml报文转对象

/**

* 解析xml报文，转化为对象

* @param string xml报文

* @return 对象

*/

@PostMapping(value = "/message", consumes = "application/xml")

public Root xmlToBean(@RequestBody String string) {

Root rootInfo=new Root();

try {

JAXBContext jaxbContext = JAXBContext.newInstance(Root.class);

Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();

rootInf=(Root)unmarshaller.unmarshal(new StringReader(string));

} catch (JAXBException e) {

e.printStackTrace();

}

return rootInf;

}

xml文件转对象

/**

* 解析xml文件，转化为对象

* @param string 文件路径

* @return

*/

@PostMapping(value = "/xmlByFile")

public Root xmlToBeanByFile(@RequestBody String string) {

Root rootInf=new Root();

File file=new File(string);

try {

JAXBContext jaxbContext = JAXBContext.newInstance(Root.class);

Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();

rootInf = (Root) unmarshaller.unmarshal(file);

} catch (JAXBException e) {

e.printStackTrace();

}

return rootInf;

}

对象转xml文件和xml报文   默认报文头与要生成的报文头不相符，因此去掉

/**

* 将对象转化为xml文件及xml报文

* @param rootInf

* @return

*/

@PostMapping("/beanToXml")

public String beanToXml(@RequestBody RootInf rootInf) {

String result = "";

try {

JAXBContext jaxbContext = JAXBContext.newInstance(RootInf.class);

Marshaller marshaller = jaxbContext.createMarshaller();

marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);//格式化输出

marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");//编码格式

marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true);//去掉默认报文头

StringWriter writer = new StringWriter();

writer.write("");//重写报文头

writer.write("\n");

marshaller.marshal(rootInf, writer);

result = writer.toString();

//写入到xml文件中

BufferedWriter bufferedWriter=new BufferedWriter(new FileWriter(new File("要写入的xml文件位置")));

bufferedWriter.write(result);

bufferedWriter.close();

} catch (JAXBException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

return result;

}
