1.xml报文转json

//接收xml报文转json
//orgmsg xml二进制数组,transcode 接口名称,每一个接口一个取值规则,secuno 发起方id
//接收xml报文
Sting message = new String(orgmsg,"GB18030");
//定义map接收转换后的报文
Map<String,String> json = new HashMap<>();
try{
	//根据接口获取解包配置
	//BaseXpathConf 存放xml报文路径 对应的jsonkey配置;
	BaseXpathConf xpathConf = confs.get(transcode);
	if(xpathConf == null){
		//抛出异常
	}
	//文本对象接收xml报文
	Document doc = DocumentHelper.parseText(message);
	//循环xpathConf ,解包配置unpack,转为json对象
	//例如,unpach放的key:xml标签路径,value:jsonkey
	Map<String,String> unpackConf = xpathConf.getUnpachConf();
	//循环解包
	for(Map.Entry<String,String> conf:unpachConf.entrySet){
		String value = getValueByRequest(doc,conf.getKey);
		if(value != null){
			json.put(conf.getValue(),value);
		}
	}
	

}


private String getValueByRequest(Document doc,String key){
	final List list = doc.selectNodes(key);
	if(list == null){
		return null;
	}
	//集合中只有一个值 的处理方案
	if(list.size() ==1){
		if(list.get(0) instanceof Node){
			return ((Node)list.get(0)).getText();
		}else if(list.get(0) instanceof String){
			return list.get(0).toString();
		}
	}
	//集合中存在多个值的处理方案
	List<String> res = new ArrayList<>();
	Object item = null;
	for(int i=-0;i<list.size();i++){
		item = list.get(i);
		if(list.get(0) instanceof Node){
			res.add(((Node)item).getText());
		}else if(list.get(0) instanceof String){
			res.add(item.toString());
		}
	}
	return JSON.toJSONString(res);

}

2.json转xml

//根据交易吗获取解包配置
//BaseXpathConf 存放xml报文路径对应的jsonkey,
//例如:加包:pach("xml路径","josnkey");
BaseXpathConf xpathConf = confs.get(transcode);
if(xpathConf == null){
	//抛出异常
}
//创建文本对象
Document doc = DocumentHelper.createDocument();
//获取xml报文模板,xml报文路径和jsonkey的对应关系;
Map<String,String> packConf = xpath.getPackConf();
for(Map.Entry<String,String> conf:packConf.entrySet()){
	//从json对象中,根据pack配置的jsonkey,获取属性值
	Object value = json.get(conf.getValue());
	if(value != null){
		DocumentHelper.makeElement(doc,conf.getkey()).setText(value.toString());

	}else{
		DocumentHelper.makeElement(doc,conf.getkey()).setText(“”);
	}

}

//xml报文转二进制数组
byte[] messageBytes = doc.getRootElement().asXML().getByte("UTF-8");
byte[] mesTextBytes = new String(messageBytes,"UTF-8").getBytes("GB18030");

//拼接xml报文头标签,属性,例如:<SMTF len = "11" seq = "1">
int len =12+mesTextBytes.length;
//开始组装
StringBUilder sh =new StringBuilder("<SMIF len =\"">");
sh.append(String.format("%05d",len));
sh.append("\" seq = \"1"");
sh.append("\">");
//拼接xml报文体
sh.append(new String(mesTextBytes,"gbk") );
sh.append("</SMIF>");

return sb.toString().getBytes("gbk");

额外补充,配置的xml模板,以及$参数动态匹配的方式

import java.io.StringWriter;
import java.util.Map;

import freemarker.cache.StringTemplateLoader;
import freemarker.template.Configuration;
import freemarker.template.Template;
	//参数:
	Map dataMap = new HashMap();
	String name = DATABLOCK.SERVERPARAM.NAME;
	String detail = DATABLOCK.SERVERPARAM.DETAIL;
	dataMap.put("Name",name);
	dataMap.put("Detail",detail);
	
	//获取模板
	String templateContent = DATABLOCK.SERVER_RETURN_PARAM.DATA.TEMPLAGE;

//调用方法
	Tempt tempt = new Tempt();
	String result = tempt.getText(dataMap,templateContent);
	//上述字符串就可以通过转成map

//封装方法
public class Tempt{
  public String getText(Map dataMap, String templateContent){
  	 String restring = "";
	try {
		//模板配置
		 Configuration cfg = new Configuration();
		 //字符串模板加载器
		 StringTemplateLoader stringLoader = new StringTemplateLoader();
		 stringLoader.putTemplate("templateName", templateContent);
		 cfg.setTemplateLoader(stringLoader);
	    //获取模板
	Template template = cfg.getTemplate("templateName", "utf-8");
		//模板解析输出
		StringWriter writer = new StringWriter();
		//执行模板解析处理
		template.process(dataMap, writer);
		//输出结果
		restring=writer.toString();
		writer.close();
		System.out.println(restring);
		return restring;
		} catch (Exception e) {
		e.printStackTrace();
		}
		return restring;
  }
}
