SpringBoot启动的时候不去校验数据库连接配置是否正确

 1 @Component
 2 public class ApplicationContextHelper implements ApplicationContextAware {
 3 
 4     private static ApplicationContext context;
 5 
 6     @Override
 7     public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
 8         try {
 9             context = applicationContext;
10             // ===== 在项目初始化bean后检验数据库连接是否
11             DataSource dataSource = (DataSource) context.getBean("dataSource");
12             dataSource.getConnection();
13         } catch (Exception e) {
14             e.printStackTrace();
15             // ===== 当检测数据库连接失败时, 停止项目启动
16             System.exit(-1);
17         }
18     }

20     public ApplicationContext getApplicationContext() {
21         return context;
22     }
