我有一个maven项目，它在本地运行良好（在spring工具套件中，右键单击project=>runas=>spring boot app）。
我们专门使用c3p0依赖项来创建oracle数据源：

<dependency>
        <groupId>c3p0</groupId>
        <artifactId>c3p0</artifactId>
        <version>0.9.1.2</version>
    </dependency>

然而，这个应用程序是打算安装在美国焊接学会和它的失败。一旦这个应用程序部署到aws上，我就会得到这些错误（我们没有使用任何线程或类似的称为timer-1的线程）：

有什么问题吗？我不知道是否需要完整的pom.xml或assembly.xml来找出发生了什么。
