edi to java

最近需要对接 东方国际  edi 报文

下面，就简单描述一下过程。

首先，放上参考资料：都很有帮助

参考链接：

1 有嵌套对象的例子，而且很有帮助

https://blog.csdn.net/yzjdt/article/details/28589493 

2 smooks example ：

https://github.com/smooks/smooks-examples

一，项目结构

 

1 MainDongFang是测试类

2 model.modelEDI.dongfang 是 java bean

3 resources.testDongFang 存放

①  input-message.edi 测试edi数据 

②  smooks-config.xml 配置文件

③  edi-to-java-order-mapping.xml 映射文件

二，引入smooks

    <dependency>
      <groupId>org.milyn</groupId>
      <artifactId>milyn-smooks-all</artifactId>
      <version>1.7.0</version>
    </dependency>

三，

1 数据 input-message.edi

这里为了简洁，我只映射  00,03,47  的字段

2 配置smooks-config.xml 

jb:wiring ：代表引用类型

jb:value ：代表基本类型

3 edi-to-java-order-mapping.xml

---- medi:description  

segment：换行符

field：字段分隔符

component：根据某一列的分隔符再次分割。

escape：转义符  

----medi:segment

segcode：行指令

xmltag：我看下来，是smooks-config.xml 中的createOnElement

truncatable ： 可空（注意segment和field都要加！）

----medi:segmentGroup  代表循环

maxOccurs ： 最大循环次数，-1代表多个。

minOccurs：最小循环次数，0代表可能没有。

----medi:segment segcode=99

这个是海关要求，需要一个总行数。可以没有对应实体。

四，实体类

1，DongFangOrder

 
@Data
public class DongFangOrder {
    private HEAD_00 head_00;
    private BL_03 bl_03;
    private List<CARGO_DESCRIPTION_47> cargo_description_47s;
 
}

2，Head_00

@Data
public class HEAD_00 {
    private String messageType;     //报文类型
    private String fileDescription; //文件说明
 
    private String fileFunction;    //文件功能
 
    private String sendCode;        //发送方代码
    private String receiverCode;    //接收方代码
    private Date fileCreateTime;    //文件建立时间
 
}

3，BL_03

@Data
public class BL_03 {
    private String typeOfBLFrom;        //提单类型
    private String placeOfBLIssueCode;  //提单签发地代码
    private String placeOfBLIssue;      //提单签发地
    private String dateOfIssue;         //签发日期
    private Integer numberOfOriginalBL; //正本提单份数
    private String prepaidAt;           //预付地点
    private String payableAt;           //到付地点
 
}

4，Cargo_Description_47

@Data
public class CARGO_DESCRIPTION_47 {
    private String cargoDescription;    //货物描述
 
}

五，测试

直接调用 smooks的example中例子就可以了。

 
package com.kintech.webEDI;
 
import org.milyn.Smooks;
import org.milyn.SmooksException;
import org.milyn.container.ExecutionContext;
import org.milyn.event.report.HtmlReportGenerator;
import org.milyn.io.StreamUtils;
import org.milyn.payload.JavaResult;
import org.xml.sax.SAXException;
 
import javax.xml.transform.stream.StreamSource;
import java.io.*;
 
/**
 * Simple example main class.
 *
 * @author <a href="mailto:tom.fennelly@gmail.com">tom.fennelly@gmail.com</a>
 */
public class MainDongFang {
 
    private static byte[] messageIn = readInputMessage();
 
    private final Smooks smooks;
 
    protected MainDongFang() throws IOException, SAXException {
        // Instantiate Smooks with the config...
        smooks = new Smooks("testDongFang/smooks-config.xml");
    }
 
protected JavaResult runSmooksTransform(ExecutionContext executionContext) throws IOException, SAXException, SmooksException {
        try {
            //java bean
            JavaResult javaResult = new JavaResult();
            smooks.filterSource(new StreamSource(new ByteArrayInputStream(messageIn)), javaResult);
            //xml
//            StringResult result=new StringResult();
//            smooks.filterSource(new StreamSource(new ByteArrayInputStream(messageIn)), result);
//            System.out.println(result.getResult());
 
            return javaResult;
        } finally {
            smooks.close();
        }
    }
 
    public static void main(String[] args) throws IOException, SAXException, SmooksException {
        System.out.println("

==============Message In==============");
        System.out.println(new String(messageIn));
        System.out.println("======================================
");
 
        pause("The EDI input stream can be seen above.  Press 'enter' to see how this stream is transformed into an Order Object graph...");
 
        MainDongFang smooksMain = new MainDongFang();
        ExecutionContext executionContext = smooksMain.smooks.createExecutionContext();
        JavaResult result = smooksMain.runSmooksTransform(executionContext);
 
 
        System.out.println("
==============EDI as Java Object Graph=============");
        System.out.println(result.getBean("order"));
        System.out.println("======================================

");
 
        pause("And that's it!  Press 'enter' to finish...");
    }
 
    private static byte[] readInputMessage() {
        try {
            return StreamUtils.readStream(Main.class.getResourceAsStream("../../../testDongFang/input-message.edi"));
        } catch (IOException e) {
            e.printStackTrace();
            return "<no-message/>".getBytes();
        }
    }
 
    private static void pause(String message) {
        try {
            BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
            System.out.print("> " + message);
            in.readLine();
        } catch (IOException e) {
        }
        System.out.println("
");
    }
 
    public JavaResult runSmooksTransform() throws IOException, SAXException {
        ExecutionContext executionContext = smooks.createExecutionContext();
        return runSmooksTransform(executionContext);
    }
}

需要注意的是：runSmooksTransform 方法中，使用了工厂模式，

底层会通过 TransformFactory工厂接收你传入的  JavaResult / StringResult等等，来产生不同的结果。

JavaResult返回java bean

StringResult 返回 xml String

其他类型，暂时我没有研究。

 

六，结果
