Question

我正在将战争部署到两个instances(containers)，同时部署了tomcat image ..当我在第一个实例中部署战争时，它显示以下log并且工作正常

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

resource and provider classes in the packages:

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

但是当我尝试将同一个战争（sat-metrics.war）上传到另一个容器时，我得到以下日志并且它无法正常工作

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:

我发现差异在第一个container日志中，它能够找到根类＆＃39;但在第二个container日志中没有root classes信息。

问题可能是什么，我该如何解决？

Answer 1

我能够找到问题，在 WEB-INF / lib 文件夹中有 Jersey JAR文件的两个版本。消除冲突后，它起作用了。

tomcat日志未显示com.sun.jersey.api.core.ScanningResourceConfig.logClasses找到的根资源类
