Java Spring Hibernate application runs on local, but not in aws's ecs docker

问题描述:

Dear Java & Docker Masters,

Have you encounter issue that pulls out your hair? Try this:

I have a Java Spring Hibernate web application that able to run successfully on my local that build via Gradle. IT is compile using Oracle JDK 1.8.0_101. It runs under Tomcat 7.0.72 (and tomcat runs Open on JDK 1.8.0_102). It runs the war perfectly well. Why do I have such different jdk version? because i want to mimic the dev server below.

My Dev server is a docker under aws ecs, with only one container image. And this container image uses the tomcat:7.0.72-jre8 image base. The same war application that is running inside the container throws the following error:

Error creating bean with name 'agencyRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not an managed type: class com.mnetmobile.data.entities.Agency

I drag that war file, and runs on my local, and it works like a champ. All JDK versions are the same, tomcat version are the same. the only thing different, is a windows 7 laptop, vs an ubuntu linux and runs docker. (All the path different is N/A because there are all relative path)

Any idea which hole i might have missed?

网友答案:

Somehow there must be some difference in the configuration of the two Tomcat servers. Since the Java version, the Tomcat version, and the war file are all the same; there must be some difference in the Tomcat configuration, either in the Tomcat lib folder, or the context.xml or server.xml or someplace.
