我该如何解决？

Answer 1

我发现您的项目在我的末端运行良好，您可能会尝试在末端完成一些工作。

尝试更改为spring.datasource.driverClassName=com.mysql.jdbc.Driver
从主要班级中删除@ComponentScan()，然后仅将@SpringBootApplication留在那里。

@SpringBootApplication 公共类TrialApplication {
```
public static void main(String[] args) {
    SpringApplication.run(TrialApplication.class, args);
}
```
}
按项目清理项目->重建/清理或运行命令mvn clean install或删除.m2/repository或重新导入项目或重新启动IDE /系统可能会有所帮助。
