利用xstream將對象轉換成xml格式字符串

//封裝請求的參數到實體類中
 PWBRequest pwbRequest = new PWBRequest();
 Header header = new Header();
 header.setRequestTime(DateConverter.getDate(new Date()));
 header.setApplication("Send");
 pwbRequest.setHeader(header);

 pwbRequest.setTransactionName("POS");

 IdentityInfo identityInfo = new IdentityInfo();
 identityInfo.setCorpCode("TES");
 identityInfo.setUserName("admin");
 pwbRequest.setIdentityInfo(identityInfo);

 PosTradeTime posTradeTime = new PosTradeTime();
// posTradeTime.setBeginTime(sucTimeMapper.findSucTimeById(1));
// posTradeTime.setEndTime(DateConverter.getDateTime(new Date()));
 posTradeTime.setBeginTime("2018-11-30 11:53:04");
 posTradeTime.setEndTime("2018-11-30 18:53:04");
 pwbRequest.setPosTradeTime(posTradeTime);

 XStream xStream = XStreamUtil.getxStream();
 xStream.alias("PWBRequest", PWBRequest.class);
 xStream.alias("PWBResponse", PWBResponse.class);
 xStream.alias("identityInfo", IdentityInfo.class);
 xStream.alias("header", Header.class);
 xStream.alias("posTradeTime", PosTradeTime.class);
 xStream.alias("posTradeData",PosTradeData.class);
 //轉換成xml格式的字符串,反過來用formXML()
 String xmlMsg = xStream.toXML(pwbRequest);

xmlMsg成如下xml格式:

<PWBRequest>

<transactionName>POS</transactionName>

<header>

<application>Send</application>

<requestTime>2018-10-20</requestTime>

</header>

<identityInfo>

<corpCode>TES</corpCode>

<userName>admin</userName>

</identityInfo>

<posTradeTime>

<beginTime>2018-11-29 18:53:04</ beginTime >

<endTime>2018-11-30 18:53:04</ endTime>

</ posTradeTime>

</PWBRequest>
