从java对象准备edi数据

我是edi数据的新手。我正在使用smooks api读取edi数据，并能够将其解析为java对象。我想将java对象转换为edi数据，因为我没有得到太多信息。下面是我试图从edi文件读取并创建java对象的示例-

customOrder.edi - COR*130*PINGPONG02*You got it to work*1230
---------------
POJO -
------
    public class CustomOrder implements Serializable{
    private int number;
    private String sender;
    private String message;
    private int price;
    // setter and getter
    }
custom-order-mapping.xml -

    <?xml version="1.0" encoding="UTF-8"?><medi:edimap xmlns:medi="http://www.milyn.org/schema/edi-message-mapping-1.3.xsd">

    <medi:delimiters segment="&#10;" field="*" component="^" sub-component="~" />

    <medi:segments xmltag="CustomOrder">
        <medi:segment segcode="COR" xmltag="co">
            <medi:field xmltag="number" />
            <medi:field xmltag="sender" />
            <medi:field xmltag="message" />
            <medi:field xmltag="price" />
        </medi:segment>
    </medi:segments>
</medi:edimap>

        CustomOrder custOrder = (CustomOrder) result.getBean("customer");
        // Need to get to edi data from java object custOrder
       // Please help me - this part of code

我想从java对象准备edi数据。如果除了Smooks之外还有其他api/框架也能做到这一点，那对我来说没问题。请让我知道，谢谢。

我搜索了它，从Smooks论坛了解到，要从java对象准备edi数据，我们必须使用Edifact java编译器（EJC）。 上面的示例是从edi数据准备java对象。 Pojo类必须实现

ediwriteable

并重写

write

方法-

public class CustomOrder implements Serializable, EDIWritable{
private int number;
private IntegerDecoder numberDecoder;
private String sender;
private String message;
private int price;
private IntegerDecoder priceDecoder;
public CustomOrder() {
    numberDecoder = new IntegerDecoder();
    priceDecoder = new IntegerDecoder();
}
public int getNumber() {
    return number;
}
public void setNumber(int number) {
    this.number = number;
}
public void setSender(String sender) {
    this.sender = sender;
}
public String getSender() {
    return sender;
}
public String getMessage() {
    return message;
}
public void setMessage(String message) {
    this.message = message;
}
public int getPrice() {
    return price;
}
public void setPrice(int price) {
    this.price = price;
}
public  void write(Writer writer, Delimiters delimiters) throws IOException {
    // TODO Auto-generated method stub
     Writer nodeWriter = writer;

        if(number != 0) {
            nodeWriter.write(delimiters.escape(numberDecoder.encode(number)));
        }
        nodeWriter.write(delimiters.getField());

        if(sender != null) {
            nodeWriter.write(delimiters.escape(sender.toString()));
        }
        nodeWriter.write(delimiters.getField());

        if(message != null) {
            nodeWriter.write(delimiters.escape(message.toString()));
        }
        nodeWriter.write(delimiters.getField());
        if(price != 0) {
            nodeWriter.write(delimiters.escape(priceDecoder.encode(price)));
        }
        //nodeWriter.write(delimiters.getField());

        writer.write(delimiters.getSegmentDelimiter());
        writer.flush();

}
}

接下来，我们要准备pojo类的工厂-

public class CustomOrder implements Serializable, EDIWritable{
private int number;
private IntegerDecoder numberDecoder;
private String sender;
private String message;
private int price;
private IntegerDecoder priceDecoder;
public CustomOrder() {
    numberDecoder = new IntegerDecoder();
    priceDecoder = new IntegerDecoder();
}
public int getNumber() {
    return number;
}
public void setNumber(int number) {
    this.number = number;
}
public void setSender(String sender) {
    this.sender = sender;
}
public String getSender() {
    return sender;
}
public String getMessage() {
    return message;
}
public void setMessage(String message) {
    this.message = message;
}
public int getPrice() {
    return price;
}
public void setPrice(int price) {
    this.price = price;
}
public  void write(Writer writer, Delimiters delimiters) throws IOException {
    // TODO Auto-generated method stub
     Writer nodeWriter = writer;

        if(number != 0) {
            nodeWriter.write(delimiters.escape(numberDecoder.encode(number)));
        }
        nodeWriter.write(delimiters.getField());

        if(sender != null) {
            nodeWriter.write(delimiters.escape(sender.toString()));
        }
        nodeWriter.write(delimiters.getField());

        if(message != null) {
            nodeWriter.write(delimiters.escape(message.toString()));
        }
        nodeWriter.write(delimiters.getField());
        if(price != 0) {
            nodeWriter.write(delimiters.escape(priceDecoder.encode(price)));
        }
        //nodeWriter.write(delimiters.getField());

        writer.write(delimiters.getSegmentDelimiter());
        writer.flush();

}
}

客户订单工厂 一旦CustomOrder对象就绪，如上面的Main类所示。我们必须使用此对象转换为edi数据格式。这是完整的主类-

Main class
----------
Main smooksMain = new Main();
ExecutionContext executionContext = smooksMain.smooks.createExecutionContext();
org.milyn.payload.JavaResult result = smooksMain.runSmooksTransform(executionContext);
CustomOrder custOrder = (CustomOrder) result.getBean("customer");
// Prepare edi data from java object custOrder
CustomOrderFactory customOrderFactory = CustomOrderFactory.getInstance();
OutputStream os = new FileOutputStream("createdEDIFile.edi");
customOrderFactory.toEDI(custOrder, new OutputStreamWriter(os));    
System.out.println("Edi file is created from java object");

就这样。希望能有帮助。谢谢
