前言
springboot打成可执行jar包，提供了容器环境。怎么样回调一次性任务（非定时任务） CommandLineRunner、ApplicationRunner 接口是在容器启动成功后的最后一步回调（类似开机自启动）。
1：CommandLineRunner方案
@Order(1) //控制顺序
@Component
public class PrintSuccessRunner implements CommandLineRunner {
@Override
public void run(String... args) throws Exception {
System.out.println("PrintSuccessRunner:i am call back~");
}
}
@Order(2)
@Component
public class PrintStartRunner implements CommandLineRunner {
@Override
public void run(String... args) throws Exception {
System.out.println("PrintStartRunner:i am call back~");
}
}
2: ApplicationRunner方案
@Component
public class MyApplicationRunner implements ApplicationRunner{
@Override
public void run(ApplicationArguments args) throws Exception {
System.out.println("===MyApplicationRunner==="+ Arrays.asList(args.getSourceArgs()));
System.out.println("===getOptionNames========"+args.getOptionNames());
System.out.println("===getOptionValues======="+args.getOptionValues("foo"));
System.out.println("==getOptionValues========"+args.getOptionValues("developer.name"));
}
}
还没搞明白，打了包之后如何传参 -_-
