java - tomcat 日志不显示 com.sun.jersey.api.core.ScanningResourceConfig.logClasses 找到根资源类

Question

我正在将 war 部署到两个 instances(containers) 中，其中部署了相同的 tomcat image。当我在第一个实例中部署 war 时，它显示以下 log 并且工作正常

25-Jan-2018 11:06:29.523 INFO [localhost-startStop-2]

application archive [/usr/local/tomcat/webapps/sat-metrics.war] has finished in [9,964] ms

但是当我尝试将相同的 war(sat-metrics.war) 上传到另一个容器时，我得到以下日志并且它不起作用

25-Jan-2018 11:05:38.056 INFO [localhost-startStop-3] com.sun.jersey.api.core.PackagesResourceConfig.init Scanning for root resource and provider classes in the packages:

我发现的区别是在第一个 container 日志中它能够找到“根类”，但在第二个 container 日志中没有 root classes信息。

可能是什么问题，我该如何解决

Answer 1

我找到了问题所在，WEB-INF/lib 文件夹中有两个版本的 Jersey JAR 文件。消除冲突后，它起作用了。
