Springboot启动时报错 If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.

产生这个错误的原因是springboot的自动配置，如果你没有配置DataSource就会导致下图这个错误

解决方案1

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)//排除自动配置
public class ErukaServerMain {
    public static void main(String[] args) {
        SpringApplication.run(ErukaServerMain.class,args);
    }
}

如果以上方法不行那就，将pom文件带有数据库相关的删除，例如：jdbc、mysql-connect等等
