1.如查看数据库的连接池信息
@RunWith(SpringRunner.class) @SpringBootTest public class RobotsApplicationTests { @Autowired DataSource dataSource; @Test public void test(){ System.out.println(dataSource.getClass()); } }
2.或者继承CommandLineRunner接口
CommandLineRunner:表示在项目启动后执行的功能,需要只需的内容写在其run()方法中,如:
@SpringBootApplication @EnableScheduling @ComponentScan(basePackages={"com.cmit.hall.plat","com.cmit.hall.pub"}) @ServletComponentScan(value= {"com.cmit.hall.pub.interceptor","com.cmit.hall.plat.config","com.cmit.hall.pub.session"}) @EnableRedisHttpSession(maxInactiveIntervalInSeconds=1800) public class PlatApp implements CommandLineRunner { @Autowired DataSource dataSource; public static void main(String[] args) { SpringApplication.run(PlatApp.class, args); } @Override public void run(String... args) throws Exception { System.out.println(">>>>>>>>>>>>>>>服务启动执行,执行加载数据等操作<<<<<<<<<<<<<"); System.out.println("DATASOURCE = " + dataSource); } }
