我该如何解决?

推荐答案

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.

I found your project to be running fine at my end, few things you might try to work at your end.

  1. 尝试更改为spring.datasource.driverClassName=com.mysql.jdbc.Driver

从主类中移除@ComponentScan()，然后将@SpringBootApplication留在此处.

Remove @ComponentScan() from main class and just leave @SpringBootApplication there.

    @SpringBootApplication
    public class TrialApplication{    
        public static void main(String[] args) {
            SpringApplication.run(TrialApplication.class, args);
        }       
    }

  1. 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.
  1. Clean your project by project-->rebuild/clean or run command mvn clean install or removing .m2/repository or re-import project or restarting IDE/system might help.
