在静态方法中获取properties /yml 配置文件中的信息

custom:
  socket:
    max-content-length: 2147483647
    connect-timeout-millis: 3000
    proxy-port: 8088
    client-thread-num: 2
    event-thread-num: 4
    server-ip: 10.218.51.214
    server-port: 8090

@Component    //加此注解
public class ProxyConfig {
 public  static Integer proxyPort; //
 
 //添加set方法 不能是static方法不然获取为null
  @Value("${custom.socket.proxy-port}")
    public  void setProxyPort(Integer proxyPort) {
        ProxyConfig.proxyPort = proxyPort;
    }

public static IntegergetProxyPort(){
   
       return ProxyConfig.proxyPort;
}
