我是靠谱客的博主热心毛衣，这篇文章主要介绍SpringBoot的ApplicationRunner和CommandLineRunner，现在分享给大家，希望可以做个参考。

如果你需要在你的SpringBoot启动完成之后实现一些功能，那么可以通过创建class实现ApplicationRunner和CommandLineRunner来完成：

@Component
public class ApplicationRunnerTest implements ApplicationRunner {
@Override
public void run(ApplicationArguments args) throws Exception {
System.out.println("========>> ApplicationRunner.run");
for (String sourceArg : args.getSourceArgs()) {
System.out.println(sourceArg);
}
for (String optionName : args.getOptionNames()) {
System.out.println(optionName + " = " + args.getOptionValues(optionName));
}
System.out.println("========>> End");
}
}
