springBoot 采坑 报错找不到数据库连接

springBoot 报错找不到数据库连接

报错记录

---

APPLICATION FAILED TO START

---

Description:

Failed to auto-configure a DataSource: ‘spring.datasource.url’ is not specified and no embedded datasource could be auto-configured.

Reason: Failed to determine a suitable driver class

Action:

Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

错误原因：

当前springBoot项目引入数据库连接jar包，但是没有配置数据连接属性。

解决办法：

1.如果不需要连接数据库，将连接数据库的jar删除，重新启动即可。
2.如果父项目带的，本项目不用，排除即可

@SpringBootApplication(exclude = { 
		DataSourceAutoConfiguration.class,
		DataSourceTransactionManagerAutoConfiguration.class,
		HibernateJpaAutoConfiguration.class })
public class AppXxlSso {

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

}
