java处理edi的测试类

以下是一个使用Java处理EDI文件的示例代码：

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.List;

import org.milyn.edi.unedifact.d96a.D96AInterchangeFactory;
import org.milyn.edi.unedifact.d96a.INVOic;
import org.milyn.smooks.edi.unedifact.model.UNEdifactInterchange;
import org.milyn.smooks.edi.unedifact.model.UNEdifactMessage;

public class EdiTest {

    public static void main(String[] args) throws IOException {
        File ediFile = new File("path/to/edi/file");

        // Create the EDI interchange factory.
        D96AInterchangeFactory factory = D96AInterchangeFactory.getInstance();

        // Read the EDI file.
        FileInputStream fis = new FileInputStream(ediFile);
        UNEdifactInterchange interchange = factory.fromUNEdifact(fis);

        // Process the INVOic message.
        if(interchange.getMessages() != null && !interchange.getMessages().isEmpty()){
            UNEdifactMessage message = interchange.getMessages().get(0);
            if(message.getMessageHeader().getMessageType().equals("INVOIC")){
                INVOic invoice = (INVOic) message.getMessage();
                List<INVOic.SG1Group> sg1Groups = invoice.getSG1Group();
                // Process the SG1 groups.
                // ...
            }
        }

        fis.close();
    }

}

这里使用了Milyn EDI处理框架来解析EDI文件，你可以根据自己的需要选择其他框架或者自行编写解析代码。
