我使用maven程序集插件创建了一个胖罐。以下是隐藏了一些敏感细节的pom文件： -

我可以从eclipse运行代码，但是我需要部署一个胖jar，我在封装阶段在maven中创建了它。

然而，当我尝试使用以下方式运行jar时： - 

java -jar target/labs-engine-0.0.1-SNAPSHOT-jar-with-dependencies.jar

它给出了以下例外： - 

Exception in thread "main" java.sql.SQLException: No suitable driver found for jdbc:mysql://X-Y-Z.com:3306/labs_staging

现在创造胖罐时我缺少什么？请注意： -

  1. mysql-connector包含在pom.xml中。
  2. 我能够在Eclipse中运行
  3. com.mysql.jdbc包存在于创建的fat jar中。

    4. 修改 输出mvn clean install

尝试下一个修补程序。

使用下一个内容添加到项目资源O(logN)文件中：

META-INF/services/java.sql.Driver
构建之后

确保com.mysql.jdbc.Driver com.mysql.fabric.jdbc.FabricMySQLDriver 文件（它是普通的zip文件，将其重命名为内部）包含具有正确内容的文件。

这不是最好的解决方案，但如果它有帮助我们可以找到一个。
