我目前正在评估 smooks (www.smooks.org)。它看起来就像我们需要的一样,但我在让一个简单的例子工作时遇到了问题。
我有一个 ant 脚本,它可以下载我所有的依赖项,包括 EDIFACT 消息的映射和绑定 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,但出现了一些不期望出现的块(见下文)。所以我想知道我是否缺少一些配置(注意日志输出中的前几行)。
有人与 Smooks 的 EJC 合作过吗?我怎样才能获得有关它抱怨的线路的更多信息?
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:

当我删除前导 UNA 和 UNB 片段时,它会出现以下异常:([APERAK][D:00B:UN]。必须至少有 1 个片段 [BGM] 实例)。有一个 BGM 部分,所以我不确定它为什么抱怨。
Caused by: org.milyn.edisax.EDIParseException: EDI message processing failed [APERAK][D:00B:UN]. Must be a minimum of 1 instances of segment [BGM]. Currently at segment number 2.

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 smooks 接受回车和空格以及两个主要的 UNA/UNB 段?我可能跳过了消息处理 smooks 通常做的某些部分。
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。我已经尝试过了,但似乎没有什么不同。我也试过用这个来配置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>
再次没有成功。
我觉得 D00AInterchangeFactory (或您使用的每个版本)以不同方式配置其 EDIParser 并且忽略了 ignoreNewLines 。
有没有办法获得 InterchangeFactory 正在使用的 EDIParser?
