我试图将 xml 文件解析为 flatefile。除了最后,一切都很好。在调试模式下,无限循环的原因是 org.springframework.batch.item.xml.StaxEventItemRe ader.class 中的 moveCursorToNextFragment(reader) 方法。
在这部分方法中更精确
while (reader.peek() != null && !reader.peek().isStartElement()) {
reader.nextEvent();
}
似乎这些条件不足以识别文件的结尾。我用这段代码替换这部分代码以确保文档测试结束
while (reader.peek() != null && !reader.peek().isStartElement() && !reader.peek().isEndDocument()) {
reader.nextEvent();
}
if (reader.peek() == null || reader.peek().isEndDocument()) {
return false;
}
在我的上下文文件和 INSEE xmlfile 的链接下方:http://lei-france.insee.fr/Telechargement.do我 总是拿完整的文件。
这是我的上下文文件
