以maven项目为例：
首先在pom.xml中配置依赖
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
生成报文类文件的方法
public static void main(String[] args) {
String str=”SerialNumber,ProjectNo,RepaymentType,AccountType,BankID,BankAccountName,BankAccountNumber,”
+ "BankProvince,BankCity,IdentificationType,IdentificationNumber,PaymentAccountName,PaymentAccountNumber,Amount,Remark";
String\[\] strs=str.split(",");
String con="";
for (int i = 0; i < strs.length; i++) {
con+=" @XStreamAlias(""+strs\[i\]+"")
“;
con+=” private String “+strs[i].substring(0,1).toLowerCase()+strs[i].substring(1)+”;
“;
con+=”
“;
}
System.out.println(con);
}
基础类BeanToXml, XmlToBean
package com.xstreamdemo.base;
import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.io.xml.DomDriver;
public class BaseStream {
public String toXml(){
XStream xStream = new XStream();
xStream.autodetectAnnotations(true);
xStream.aliasSystemAttribute(null, "class"); // important remove class attribute
String str = xStream.toXML(this);
//********* 去每行缩进，根据不同的报文可选 *********/
str=str.trim();
str=str.replaceAll(" {1,}<", "<");
str=str.replaceAll("
“, “
“);
//************************************************/
return str;
}
public String toXml(boolean withHead){
if(withHead){
StringBuffer buf=new StringBuffer();
buf.append("<?xml version="1.0" encoding="UTF-8" standalone="no"?>");
buf.append("
“);
buf.append(toXml());
return buf.toString();
}else{
return toXml();
}
}
@SuppressWarnings("unchecked")
public static <T> T fromXml(String str, Class<T> cls){
XStream stream = new XStream(new DomDriver());
stream.processAnnotations(cls);
return (T)stream.fromXML(str );
}
}
巧用继承：
package com.xstreamdemo.base;
import com.thoughtworks.xstream.annotations.XStreamAlias;
import com.thoughtworks.xstream.annotations.XStreamAsAttribute;
@XStreamAlias(“Request”)
public class BaseRequest extends BaseStream {
@XStreamAlias(“version”)
@XStreamAsAttribute
private String version;
@XStreamAlias("Head")
private RequestHead head;
public String getVersion() {
return version;
}
public void setVersion(String version) {
this.version = version;
}
public RequestHead getHead() {
return head;
}
public void setHead(RequestHead head) {
this.head = head;
}
}
package com.xstreamdemo.base;
import com.thoughtworks.xstream.annotations.XStreamAlias;
import com.thoughtworks.xstream.annotations.XStreamAsAttribute;
@XStreamAlias(“Request”)
public class Request extends BaseStream {
@XStreamAlias(“version”)
@XStreamAsAttribute
private String version;
@XStreamAlias("Head")
private Head head;
@XStreamAlias("Body")
private BaseBody body;
public String getVersion() {
return version;
}
public void setVersion(String version) {
this.version = version;
}
public Head getHead() {
return head;
}
public void setHead(Head head) {
this.head = head;
}
public BaseBody getBody() {
return body;
}
public void setBody(BaseBody body) {
this.body = body;
}
}
BaseBody.java是一个空类，里面啥也没有，
然后其他的报文体继承这个类就好。
最后组装报文：
Request req = new Request();
req.setVersion(“2.1”);
RequestHead head = new RequestHead();
head.setTxCode(“4271”);
head.setInstitutionID(institutionID);
Body4271 body = new Body4271();
body.setPaymentAccountNumber(this.paymentNo);
body.setAgreementNo( NetUtil.getRandStr(32));
body.setAgreementType(“60”); // 60自动投资；20自动扣款
body.setPageUrl(pageUrl);
req.setHead(head);
req.setBody(body);
String str = req.toXml(true);
System.out.println(str);
String\[\] ps=NetUtil.getMessageAndSignature(str);
String message=ps\[0\];
String signature=ps\[1\];
但是接收报文时，不能在报文类中用父类：
package com.xstreamdemo.response;
import com.thoughtworks.xstream.annotations.XStreamAlias;
import com.xstreamdemo.base.ResponseHead;
@XStreamAlias(“Response”)
public class Response4232 {
@XStreamAlias(“Head”)
private ResponseHead responseHead;
public ResponseHead getResponseHead() {
return responseHead;
}
public void setResponseHead(ResponseHead responseHead) {
this.responseHead = responseHead;
}
@XStreamAlias("Body")
private ResBody4232 baseBody;
public ResBody4232 getBaseBody() {
return baseBody;
}
public void setBaseBody(ResBody4232 baseBody) {
this.baseBody = baseBody;
}
}
Body必须指定明确的类。
