它还包含属性文件，我们在其中定义记录器详细信息，如日志文件的路径和文件名以及logger初始化，如log4j.category.com.xxx.common.util.SDKUtil = debug，XLogger 这里我们使用在类路径中初始化的Log4.jar api。
非常感谢任何帮助。
谢谢， Himachandra。
答案 0 :(得分：0)
如果您查看org.apache.logging.log4j.util.ProviderUtil.validVersion（ProviderUtil.java:142）的代码，则它看起来像是Log4J中的错误：
private static boolean validVersion(final String version) {
for (final String v : COMPATIBLE_API_VERSIONS) {
if (version.startsWith(v)) {
return true;
}
}
return false;
}
在该库中，if (version.startsWith(v))应该为if (v.startsWith(version))，因为版本可以为空，但v绝不能为空。
请尝试使用没有此错误的较新版本的log4j。
我没有在版本中看到此问题：
我在版本中看到了这个问题：
更改版本对我来说是一个快速修复。但是，它不能解决根本的根本原因。对我来说，我认为junit-log4j-jmockit之间的某种奇怪的交互作用使版本为null。如果我以其他顺序运行测试，那么我没有问题。
