我想测试CommandLineRunner，但我无法让它工作。我只有2个类：

1. FrameworktestApplication.java
   软件包com.caido.框架测试;

import org.springframework.boot.SpringApplication;
 import org.springframework.boot.autoconfigure.SpringBootApplication;

 @SpringBootApplication
 public class FrameworktestApplication  {
     public static void main(String[] args) {
         System.out.println("Start run");
         SpringApplication.run(FrameworktestApplication.class, args);
     }

 }

1.命令行运行程序测试：
软件包com.caido.框架测试;

import org.springframework.boot.CommandLineRunner;

 public class CommandLineRunnerTest implements CommandLineRunner {
     @Override
     public void run(String... strings) throws Exception {
         System.err.println("Start CommandLineRunner");
     }
 }

当我运行应用程序时，我在屏幕上看不到“Start CommandLineRunner”。这是完整的输出：

--- exec-maven-plugin:3.0.0:exec (default-cli) @ frameworktest ---
Start run
