在与 smooks bean 绑定和 CSV 映射进行了一些斗争之后，我设法解析了一个带有空值的特定 CSV，如本问题所示。不知何故，由于 xml 配置文件验证，我在创建 smooks 实例时遇到了一些奇怪的错误（预期不同的 xml 文档结构，因此它抛出“预期 blahblah/abstract-resource-config”的东西）。所以我更新到 smooks 1.5，基本上它停止过滤输入数据。¿¿我应该改变什么才能使它从messagePath路径获取CSV并使用给定的配置过滤它？
代码块是这样的
protected List runSmooksTransform(int intType) throws IOException, SAXException, SmooksException {
Smooks smooks = null;
try {
switch (intType) {
case 0:
// Header
smooks = new Smooks("smooks-config_enc.xml");
break;
case 1:
// Detail list
smooks = SmooksFactoryServicio.getInstance().getSmooksDetalle();
break;
default:
LogServicio.doLog("[CSVParserServicio, runSmooksTransform] Tipo de archivo a procesar no reconocido.", LogServicio.CErrorLvl);
return null;
}
JavaResult javaResult = new JavaResult();
File f = new File(messagePath);
InputStream is = new FileInputStream(messagePath);
StreamSource ss = new StreamSource( is );
smooks.filterSource(ss, javaResult); //tried with file and inputstream to streamsource...
LogServicio.doLog("[CSVParserServicio, runSmooksTransform] Finaliza procesamiento archivo"+ messagePath , LogServicio.CInfoLvl);
return (List) javaResult.getBean("movimientoList");
} catch (Exception e) {
LogServicio.doLog("[CSVParserServicio, runSmooksTransform] Excepción procesando archivo: " + e.getMessage(), LogServicio.CErrorLvl);
e.printStackTrace();
} finally {
smooks.close();
}
return null;
}
