SpringBoot CommandLine如何自定义启动逻辑

要自定义SpringBoot CommandLine的启动逻辑，可以通过实现CommandLineRunner接口或ApplicationRunner接口来实现。

实现CommandLineRunner接口：

import org.springframework.boot.CommandLineRunner;import org.springframework.stereotype.Component;@Componentpublic class CustomCommandLineRunner implements CommandLineRunner {    @Override    public void run(String... args) throws Exception {        // 在这里编写自定义的启动逻辑        System.out.println("Custom command line runner is running...");    }}

实现ApplicationRunner接口：

import org.springframework.boot.ApplicationArguments;import org.springframework.boot.ApplicationRunner;import org.springframework.stereotype.Component;@Componentpublic class CustomApplicationRunner implements ApplicationRunner {    @Override    public void run(ApplicationArguments args) throws Exception {        // 在这里编写自定义的启动逻辑        System.out.println("Custom application runner is running...");    }}

这样，在SpringBoot应用启动时，会自动执行实现了CommandLineRunner或ApplicationRunner接口的类中的run方法，从而实现自定义的启动逻辑。
