使用Spring应用程序将Liquibase嵌入罐中

Question

我试图在uberjar中嵌入带有liquibase的纯Spring(不是Spring Boot)应用程序时遇到了一个特定的错误.一旦SpringLiquibase bean被初始化,它就开始寻找我不理解的东西:

WARNING 7/16/15 3:22 PM: liquibase: No Liquibase-Packages entry found in MANIFEST.MF. Using fallback of entire 'liquibase' package
WARNING 7/16/15 3:28 PM: liquibase: Error initializing SpringLiquibase

WARNING 7/16/15 3:28 PM: liquibase: Error initializing SpringLiquibase
java.io.FileNotFoundException: ServletContext resource [/liquibase] cannot be resolved to URL because it does not exist
(stacktrace again)

我知道MANIFEST.MF中的Liquibase-Package条目,并使用shade插件填充它(虽然我不知道它有什么用途)并使用shade插件,但它没有产生任何影响.什么是liquibase寻找,我该如何克服这些错误？

根据这个问题，如果您创建一个 src/main/webapp 文件夹，这个问题就会得到解决：

顺便说一句，根本原因是不存在 src/main/webapp 文件夹。作为解决方法，您可以在 @WebAppConfiguration 中创建一个指向 classpath: 实际存在的文件夹的值或设置一个值。
