XML文件格式可以根据不同的接口要求对toSendData()方法进行修改
也可以把xml报文头和报文数据单独的写成模型类：
XML编码模型类（二）：
报文头模型：
public class XMLHeadmodel {
private String HeadName1;
private String HeadName2;
private String HeadName3;
public XMLHeadmodel() {
super();
public XMLHeadmodel(String headName1, String headName2, String headName3) {
super();
HeadName1 = headName1;
HeadName2 = headName2;
HeadName3 = headName3;
public String getHeadName1() {
return HeadName1;
public void setHeadName1(String headName1) {
HeadName1 = headName1;
public String getHeadName2() {
return HeadName2;
public void setHeadName2(String headName2) {
HeadName2 = headName2;
public String getHeadName3() {
return HeadName3;
public void setHeadName3(String headName3) {
HeadName3 = headName3;
报文数据模型：
public class XMLRootmodel {
private String RootName1;
private String RootName2;
private String RootName3;
public XMLRootmodel() {
super();
public XMLRootmodel(String rootName1, String rootName2, String rootName3) {
super();
RootName1 = rootName1;
RootName2 = rootName2;
RootName3 = rootName3;
public String getRootName1() {
return RootName1;
public void setRootName1(String RootName1) {
RootName1 = RootName1;
public String getRootName2() {
return RootName2;
public void setRootName2(String RootName2) {
RootName2 = RootName2;
public String getRootName3() {
return RootName3;
public void setRootName3(String RootName3) {
RootName3 = RootName3;
xml模型类：
import java.lang.reflect.Field;
import java.nio.charset.Charset;
import java.util.HashMap;
import java.util.Map;
import java.util.Map.Entry;
public class XMLEncodeModel2 {
private XMLHeadmodel heads = null;//XML报文头
private XMLRootmodel roots = null;//XML报文数据
public void setHeads(XMLHeadmodel heads) {
this.heads = heads;
public void setRoots(XMLRootmodel roots) {
this.roots = roots;
public XMLHeadmodel getHeads() {
return heads;
public XMLRootmodel getRoots() {
return roots;
/** 产生模型对应的XML数据
* @param charset 编码
* @return
* @throws IllegalAccessException
* @throws IllegalArgumentException
public String toSendData(Charset charset) throws IllegalArgumentException, IllegalAccessException{
StringBuilder builder = new StringBuilder();
builder.append("<?xml version=\"1.0\" encoding=\"").append(charset.displayName()).append("\"?>");
builder.append("<DATA>");
builder.append("<HEAD>");
Class<?> headsclz = heads.getClass();
Field[] headsfields = headsclz.getDeclaredFields();
for (Field field : headsfields) {
field.setAccessible(true);
if(field.get(heads)!=null){
builder.append("<").append(field.getName()).append(">");
builder.append((String) field.get(heads));
builder.append("</").append(field.getName()).append(">");
}else {
System.out.println("XML报文头字段："+ field.getName() + " 为空");
builder.append("</HEAD>");
builder.append("<ROOT>");
Class<?> rootsclz = roots.getClass();
Field[] rootsfields = rootsclz.getDeclaredFields();
for (Field field : rootsfields) {
field.setAccessible(true);
if(field.get(roots)!=null){
builder.append("<").append(field.getName()).append(">");
builder.append((String) field.get(roots));
builder.append("</").append(field.getName()).append(">");
}else {
System.out.println("XML报文数据字段："+ field.getName() + " 为空");
builder.append("</ROOT>");
builder.append("</DATA>");
return builder.toString();
public static void main(String[] args) throws IllegalArgumentException, IllegalAccessException {
XMLEncodeModel2 model = new XMLEncodeModel2();
XMLHeadmodel heads = new XMLHeadmodel("headvalue1","headvalue2","headvalue3");//报文头
XMLRootmodel roots = new XMLRootmodel("rootvalue1","rootvalue2","rootvalue3");//报文数据
model.setHeads(heads);
model.setRoots(roots);
String xmlString = model.toSendData(Charset.forName("GBK"));
System.out.println(xmlString);
结果整理后和上面第一个测试一样
<?xml version="1.0" encoding="GBK"?>
<HeadName1>headvalue1</HeadName1>
<HeadName2>headvalue2</HeadName2>
<HeadName3>headvalue3</HeadName3>
</HEAD>
<RootName1>rootvalue1</RootName1>
<RootName2>rootvalue2</RootName2>
<RootName3>rootvalue3</RootName3>
</ROOT>
</DATA>
public static void main(String[] args) throws ParserConfigurationException, IOException, SAXException, DocumentException {
String str = "<?xml version=\"1.0\" encoding=\"GBK\" ?> \n" +
" <response>\n" +
代码如下（示例）：
StringBuffer str = new StringBuffer();
str.append("<?xml version=“1.0” encoding=“utf-8”?> ");
str.append("<request>");
str.append("<name>");// 内容开始标签

报文头：<?xml version="1.0" encoding="utf-8"?>
<?xml ?>：报文头格式，报文头内容放在xml和?符号中间

encoding="utf-8"：声明用xml传输数据时候用的字符编码（字符集）

XML文件结构和基本语法4.1.1 XML文件结构一个XML文件通常包含文件头和文件体两大部分1. 文件头XML文件头由XML声明与DTD文件类型声明组成。其中DTD文件类型声明是可以缺少的，关于DTD声明将在后续的内容中介绍，而XML声明是必须要有的，以使文件符合XML的标准规格。在前面的Flowers.xml文件中的第
