我正在创建一个基本的API来发送数独谜题,我在运行API时遇到了麻烦。这是我第一次尝试自己使用Spring,我遵循了与教程相同的步骤,但它一直崩溃。
这是日志。

我的应用程序属性如下,我更改了用户名和密码,但我确信我有正确的。

我真的不知道如何阅读这些错误代码,所以我复制粘贴他们,并试图找到任何东西,但似乎没有工作。
我是不是漏掉了什么?

从您的日志“Failed to load driver class org.postgresql.Driver from HikariConfig class classloader jdk.internal.loader.ClassLoaders$AppClassLoader@1d44bcfa”
看起来你的类路径上没有驱动jar

kq4fsx7k

kq4fsx7k2#

我在您的Maven pom.xml中没有看到Postgres JDBC驱动程序。我建议添加它,除非我错过了:

<!-- https://mvnrepository.com/artifact/org.postgresql/postgresql -->
<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>42.6.0</version>
</dependency>

我回去看到你有驱动程序,但没有版本。我不知道你为什么要创建scope runtime。我会改变的确保在创建包之后在包中看到JAR。
