是否可以先启动myapp-1，myapp-2然后休眠 30 秒，然后再启动myapp-3？

尝试过这个docker-compose.yml但没有运气。

version: '3'
services:
  myapp-1:
    container_name: myapp-1
    image: myapp:latest
    restart: always
  myapp-2:
    container_name: myapp-2
    image: myapp:latest
    restart: always
  test-sleep:
    image: busybox
    command: ["/bin/sleep", "30"]
    depends_on:
      - "myapp-1"
      - "myapp-2"
  myapp-3:
    container_name: myapp-3
    image: myapp:latest
    restart: always
    depends_on:
      - "test-sleep"

我有一个简单的课程

public class Pet {
    private String petName;
    private int petAge;

    public Pet() {
    }

    public Pet(String petName, int petAge) {
        this.petName = petName;
        this.petAge = petAge;
    }
}

当我试图找到参数时,我得到两个零.我仍然无法找出原因.有什么建议吗？

        Constructor[] constructors = Pet.class.getDeclaredConstructors();
        for (Constructor c : constructors) {
            System.out.println(c.getTypeParameters().length);
        }
