我们可以如下写法在boot项目启动时获取端口号

8
9
10
11
12

import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.core.env.Environment;
@Slf4j
@SpringBootApplication
public class SimpleScaffoldApplication {
public static void main(String[] args) {
ConfigurableApplicationContext context = SpringApplication.run(SimpleScaffoldApplication.class, args);
Environment environment = context.getBean(Environment.class);
log.info("端口号：{}", environment.getProperty("server.port"));
}
}

获取到端口号后我们可以存储起来供其他地方使用
