Webapp无法在具有mysql-connector-java依赖性的Tomcat上部署WAR

Question

我正在尝试将mysql-connector-java作为依赖项包括在内，以连接到我的数据库。但是，每当我尝试将其作为依赖项包括时，Web应用程序都将无法部署（我知道事实是正是这种特定的依赖关系导致了失败，因为没有该依赖项的情况下，WebApp部署就很好了）。

我从Spring Initializr获得了这个pom.xml，所以我不知道是什么原因造成的。这是我的pom.xml：

我已经尝试过：

        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <scope>provided</scope>
    </dependency>

和

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <scope>provided test</scope>
    </dependency>

，还包括最新版本的标签。他们都不工作。

固定！由于我忘记创建架构，数据库无法连接。不是由依赖项本身引起的！
