本文介绍了如何在Spring Boot应用中通过ApplicationConfig配置多个端口，包括设置服务器端口、自定义连接器并根据请求端口号返回不同响应。

步骤：

1.在配置文件添加

#端口设置
server.port=8088
server.additionalPorts: 8089,8090

2.编写ApplicationConfig.class类

import org.apache.catalina.connector.Connector;
import org.springframework.boot.web.embedded.tomcat.*;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.ArrayList;
import java.util.List;

@Configuration
public class ApplicationConfig {

@Value("${server.additionalPorts}")
private String additionalPorts;

@Bean
public TomcatServletWebServerFactory servletContainer() {
TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();
Connector[] additionalConnectors = this.additionalConnector();
if (additionalConnectors != null && additionalConnectors.length > 0) {
tomcat.addAdditionalTomcatConnectors(additionalConnectors);
}
return tomcat;
}

private Connector[] additionalConnector() {
if (this.additionalPorts==null) {
return null;
}
String[] ports = this.additionalPorts.split(",");
List<Connector> result = new ArrayList<>();
for (String port : ports) {
Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
connector.setScheme("http");
connector.setPort(Integer.valueOf(port));
result.add(connector);
}
return result.toArray(new Connector[] {});
}
}

3.启动类添加注解

@Import({ApplicationConfig.class})

4.启动项目，可监听多个端口

5.控制器根据端口号做响应设置

例：
import javax.servlet.http.HttpServletRequest;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RequestMapping("/")
@RestController
public class PayController {

   //-----------------------测试----------------------------
   @RequestMapping("/a")
   public String a(HttpServletRequest request) {
       int port=request.getServerPort();
       if(port==8088) {
           return "b";
       }
       if(port==8089) {
           return "c";
       }
       if(port==8090) {
           return "d";
       }
       return "a";
   }
}
