战争被部署到Tomcat 8.5.27。在此部署期间，实体类会动态添加到类路径上的import tensorlow

文件中。
然后，要求Hibernate 5.1.2加载包含那些实体类的持久性单元。它们被添加到persistence.xml实例中。这是部署日志的摘录，其中显示了此类加载器的转储：
java.net.FactoryURLClassLoader请注意，上述所有操作似乎都是由[INFO] [talledLocalContainer] 15-Feb-2019 15:03:46.722 INFOS [localhost-startStop-1] org.apache.catalina.core.ApplicationContext.log ** SEARCHING: generated.com.company.Baz

线程执行的。
稍后，当请求到达Web应用程序时，处理该请求的线程（localhost-startStop-1请参见下面的日志）无法找到http-nio-8080-exec-6下的类。这是此线程类加载器的转储的摘录：
generated.com.company以下是用于生成转储的代码：

为什么private static void dumpLoadedClasses() {
try {
ClassLoader myCL = Thread.currentThread().getContextClassLoader();
StringBuilder sb = new StringBuilder();
while (myCL != null) {
sb.append("ClassLoader: " + myCL);
for (Iterator<Class<?>> iter = list(myCL); iter.hasNext();) {
sb.append("\n\t" + iter.next());
}
myCL = myCL.getParent();
}
log.info(sb.toString());
} catch (Exception e) {
log.warn("", e);
}
}
没有http-nio-8080-exec-6作为上下文类加载器？
答案 0 :(得分：0)
考虑使用ClassLoader.getParent（），也许他们有共同的祖先
