1.报错信息: conditions above or defining a bean of type 'javax.sql.DataSource' in your configuration.
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class}) //@SpringBootApplication这个是在springboot初始化的时候,创建的那个主类,在main方法上生命的,
//加入exclude = {DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class}就好了;意思是不让关于数据源的配置进行自动配置
