这样子,运行以下命令即可生成两种方式的jar包了。

mvn clean package -Dmaven.test.skip=true

-rw-r--r-- 1 sky sky  11M  6月  1 12:27 wbsdk-listener-1.0.0.jar

其中wbsdk-listener-1.0.0.jar是一个可独立运行的jar包,即直接执行以下命令:

java -jar wbsdk-listener-1.0.0.jar

即可运行。可以copy到任何一台装有Java环境的服务器上运行。

original-wbsdk-listener-1.0.0.jar则只是项目的文件,它还会依赖lib目录下的jar包文件。这样子将项目和依赖文件分开打包,好处是部署的时候,如果不更新依赖,就只需要更新项目文件即可(比如快点,不然每次上传几十MB的文件到服务器~~~)
