PO JAVA MAPPING

1 , PO Java Mapping 相关包，可以从 PO NWA 直接获取，方便本地测试

2，直接实现接口  AbstractTransformation

以下为XML转JSON格式，无外层节点，直接为数据内容部分。

package com.demo.edi;

import java.io.InputStream;
import java.io.OutputStream;

import org.dom4j.document;
import org.dom4j.io.SAXReader;

import com.sap.aii.mapping.api.AbstractTransformation;
import com.sap.aii.mapping.api.DynamicConfiguration;
import com.sap.aii.mapping.api.DynamicConfigurationKey;
import com.sap.aii.mapping.api.StreamTransformationConstants;
import com.sap.aii.mapping.api.StreamTransformationException;
import com.sap.aii.mapping.api.TransformationInput;
import com.sap.aii.mapping.api.TransformationOutput;

import net.sf.json.JSON;
import net.sf.json.JSONObject;
import net.sf.json.xml.XMLSerializer;

public class LEDIBean extends AbstractTransformation {

	public LEDIBean() {
	}
	
	private static final DynamicConfigurationKey MESSAGE_ID = DynamicConfigurationKey
			.create("http://sap.com/xi/XI/System/REST", "msgid");
	
	public void transform(TransformationInput in, TransformationOutput out) throws StreamTransformationException {
		InputStream inputStream;
		OutputStream outputStream;
		inputStream = null;
		outputStream = null;

		String res = "";
		
		DynamicConfiguration conf = in.getDynamicConfiguration();
		conf.put(MESSAGE_ID, StreamTransformationConstants.MESSAGE_ID);

		try {
			SAXReader reader = new SAXReader();
			inputStream = in.getInputPayload().getInputStream();
			document document = reader.read(inputStream);
			res = xml2json(document.asXML());
			JSonObject json = JSONObject.fromObject(res);
			res = json.getString("goodsReceipts");
			out.getOutputHeader().setContentType("text/plain; charset=UTF-8");
			outputStream = out.getOutputPayload().getOutputStream();
			outputStream.write(res.getBytes("UTF-8"));
			outputStream.flush();
		}catch(Exception e){
			e.printStackTrace();
		}
	}
	
	public static String xml2json(String xml) {

		String jsonStr = "";

		XMLSerializer xmlSerializer = new XMLSerializer();
		xmlSerializer.setSkipWhitespace(true);
		xmlSerializer.setSkipNamespaces(true);
		JSON json = xmlSerializer.read(xml);
		jsonStr = json.toString(0);
		System.out.println(jsonStr);
		return jsonStr;
	}
	
}

3，发布为jar( 或者直接打包为 ZIP压缩包 ），导入PO ESR，即可使用JAVA MAPPING。
