edi - 吸烟问题

Question

我目前正在评估 smooks (www.smooks.org)。它看起来就像我们需要的，但我在使用一个简单的示例时遇到了问题。

我有一个 ant 脚本，它为我下载了所有依赖项，包括 EDIFACT 消息的映射和绑定(bind) jar。

我正在尝试使用他们的 EJC 将简单的 EDIFACT APERAK 消息转换为 Java(我正在使用 JavaSE 进行这个小测试)。转换失败，异常是某些 block 不是预期的(见下文)。所以我想知道我是否缺少某些配置(注意日志输出中的前几行)。

有人使用过 Smooks 的 EJC 吗？我如何才能获得有关它提示的线路的更多信息？

所以这是代码:

    D00BInterchangeFactory factory = D00BInterchangeFactory.getInstance();
    File file = new File("aperak.edi");
    BufferedInputStream ediSource = new BufferedInputStream(new FileInputStream(file));
    StreamResult xmlStream = new StreamResult();
    StringWriter xmlWriter = new StringWriter();
    xmlStream.setWriter(xmlWriter);
    UNEdifactInterchange interchange = factory.fromUNEdifact(ediSource);
    //System.err.println("MEssage "+xmlWriter.toString());
    if(interchange instanceof UNEdifactInterchange41){
        UNEdifactInterchange41 interchange41 = (UNEdifactInterchange41)interchange;
        for(UNEdifactMessage41 message: interchange41.getMessages()){
        Object messageObj = message.getMessage();
            System.err.println("Ref Num "+message.getMessageHeader().getMessageRefNum());
        if(messageObj instanceof Aperak){
            Aperak aperak = (Aperak)message.getMessage();
            System.err.println("Aperak "+aperak);
            }
        }
    }

当我运行它时，我得到了这个异常

实际的 EDIFACT 消息相当简单:

UNA:+.? '
UNB+UNOC:3+IMP+XXX+20110902:1024+44090560'
UNH+440905601+APERAK:D:00B:UN:IMP10'

当我删除前导 UNA 和 UNB 片段时，它会出现此异常:([APERAK][D:00B:UN]。必须至少有 1 个片段 [BGM] 实例)。有一段BGM所以我不确定它为什么会提示。

更新:当我从消息中删除回车时

UNH+440905601+APERAK:D:00B:UN:IMP10'BGM+313++9+RE'RFF+ACW:XXXXXXXXX1109020'DTM+182:201109021018:203'

它工作正常。但是我如何让 smoks 接受回车符和空格以及两个主要的 UNA/UNB 段？我可能跳过了 smooks 通常会做的消息处理的某些部分。

更新 2:发现支持 UNA/UNB 段(我的错误)，但我仍然遇到回车问题。Renat 建议在 EDIParser 上使用“ignoreNewLines”选项。我试过了，但似乎没有什么不同。我也尝试用这个配置 smooks:

<?xml version="1.0" encoding="UTF-8"?>
    <smooks-resource-list 
    xmlns="http://www.milyn.org/xsd/smooks-1.1.xsd" 
    xmlns:edi="http://www.milyn.org/xsd/smooks/edi-1.4.xsd">
        <edi:reader mappingModel="/org/milyn/smooks/edi/xsd14/edi-to-xml-mapping.xml" ignoreNewLines="true" />
    </smooks-resource-list>

再次失败。

我感觉 D00AInterchangeFactory(或您使用的每个版本)以不同方式配置其 EDIParser，忽略 ignoreNewLines。

有没有办法获取 InterchangeFactory 正在使用的 EDIParser？

Answer 1

您需要在 EDIParser 上添加启用“忽略新行”开关。您有多种方法可以做到这一点，例如您可以使用 XMLReader#setFeature()

http://download.oracle.com/javase/1.5.0/docs/api/org/xml/sax/XMLReader.html#setFeature(java.lang.String,%20boolean )

或直接通过 EDIParser 方法调用。在此处查看示例
