SpringBoot_不连接数据库启动

在META-INF/spring.factories 文件中会注册很多自动配置类,其中就包含数据源的自动配置.

org.springframework.boot.autoconfigure.EnableAutoConfiguration=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration

我们如果不连接数据库启动,需要在启动类中增加配置

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

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
public class FirstProjectApplication {
    public static void main(String[] args) {
        SpringApplication.run(FirstProjectApplication.class, args);
    }
}
