受Smooks EDI writer中提出的解决方案的启发，我有以下 Java 代码：

// Creates minimal EDI message with one field populated
EdifactV3D98AMEDPID edi = new EdifactV3D98AMEDPID();
UNBInterchangeHeader header = new UNBInterchangeHeader();
UNBInterchangeHeader.S002SenderIdentification s002SenderIdentification = new UNBInterchangeHeader.S002SenderIdentification();
s002SenderIdentification.setE0004SenderIdentification("TEST");
header.setS002SenderIdentification(s002SenderIdentification);
edi.setUNBInterchangeHeader(header);

Smooks smooks = new Smooks("edi-output-smooks-config.xml");

// Sets up access to exports specified in Smooks config
ExecutionContext executionContext = smooks.createExecutionContext();
Exports exports = Exports.getExports(smooks.getApplicationContext());
Result[] results = exports.createResults();

smooks.filterSource(executionContext, new JavaSource(edi), results);

List<Object> objects = Exports.extractResults(results, exports);
JavaResult.ResultMap map = (JavaResult.ResultMap) objects.get(0);

D98AInterchangeFactory factory = D98AInterchangeFactory.getInstance();
UNEdifactInterchange41 unEdifactInterchange = (UNEdifactInterchange41) map.get("unEdifactInterchange");

// Should output EDI message as String, but StringWriter is empty
StringWriter ediOutStream = new StringWriter();
factory.toUNEdifact(unEdifactInterchange, ediOutStream);

...使用以下 Smooks 配置：

<?xml version="1.0" encoding="UTF-8"?>
<smooks-resource-list xmlns="http://www.milyn.org/xsd/smooks-1.1.xsd"
                  xmlns:core="http://www.milyn.org/xsd/smooks/smooks-core-1.4.xsd">

    <!-- Imports D98A Edifact binding found in Maven dependency -->
    <import file="/org/milyn/edi/unedifact/d98a/message-bindingconfig.xml" />
    <import file="/org/milyn/smooks/edi/unedifact/model/r41/bindings/unedifact-interchange.xml" />

    <!-- Configures Result object for accessing EDI output -->
    <core:exports>
        <core:result type="org.milyn.payload.JavaResult"/>
    </core:exports>

</smooks-resource-list>

StringWriter 返回一个空字符串，而我曾希望/期望 Java 对象为 EDI 字符串。

有什么建议或指示吗？

我没有找到 EdifactV3D98AMEDPID、UNBInterchangeHeade 类。但我做了一个类似的测试：

UNEdifactInterchange41 edi = new UNEdifactInterchange41();
UNB41 header = new UNB41();
header.setSender(null);
Party sender = new Party();
sender.setInternalId("TEST");
header.setSender(sender);
edi.setInterchangeHeader(header);

Smooks smooks = new Smooks("edi-output-smooks-config.xml");

ExecutionContext executionContext = smooks.createExecutionContext();
Exports exports = Exports.getExports(smooks.getApplicationContext());
Result[] results = exports.createResults();

smooks.filterSource(executionContext, new JavaSource(edi), results);

List<Object> objects = Exports.extractResults(results, exports);
JavaResult.ResultMap map = (JavaResult.ResultMap) objects.get(0);

D98AInterchangeFactory factory = D98AInterchangeFactory.getInstance();
UNEdifactInterchange41 u = (UNEdifactInterchange41) map.get("unEdifactInterchange");

// Should output EDI message as String, but StringWriter is empty
StringWriter ediOutStream1 = new StringWriter();
factory.toUNEdifact(u, ediOutStream1);

我得到了相同的结果，最后是一个空字符串。

但我认为问题在于您对烟雾的使用。我只将 smooks 与 Apache Camel 一起使用，所以我不知道这是否是在 smooks 中进行转换的正确方法，但我认为在这种情况下你不必调用 smook，你的输入是一个对象 EDI，你想要以 EDI 格式打印您的对象。

你唯一需要做的就是：

UNEdifactInterchange41 edi = new UNEdifactInterchange41();
UNB41 header = new UNB41();
header.setSender(null);
Party sender = new Party();
sender.setInternalId("TEST");
header.setSender(sender);
edi.setInterchangeHeader(header);

D98AInterchangeFactory factory = D98AInterchangeFactory.getInstance();

StringWriter ediOutStream1 = new StringWriter();
factory.toUNEdifact(edi, ediOutStream1);

我已经测试过了，你得到了这个：

UNB++::TEST'

我希望这可以帮助你
