我以前工作的小程序现在失败了。我正在使用 Log4J，什么都没有改变，但是它似乎是为JDK 1.3 日志配置的。（搜索 META-INF/services）有什么可以改变的，或者我如何覆盖现在的内容？谢谢你。

奇怪的是，它正在发出 Log4J 语句直到一行JSONSerializer.toJSON(JSONData00); 然后在公共/日志对象上出错。我正在使用 json-lib-2.4-jdk15.jar。这是对公地/日志记录的要求吗？我该如何停止它，因为它需要不存在且我无法创建的路径。有什么帮助吗？

解决了。它需要具有这两个名称/值行的 commons-logging.properties

org.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogger
log4j.configuration=log4j.properties

此外，反常的是 beanutils，特别是 Dynabean。我对此没有明确的方法调用，我相信我可以重构它以消除它。HTH。
