在springboot启动报错：No qualifying bean of type 'javax.sql.DataSource' available: expected at lea

1.

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

　　这种情况 会报错 

No qualifying bean of type ‘javax.sql.DataSource‘ available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

2.

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

　　这种情况会报错：Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).

 

 

正确的应该是：

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