连接到 KNX IP 路由器的异常 - 无效参数

如何解决连接到 KNX IP 路由器的异常 - 无效参数

我正在使用 Calimero 库尝试连接到我的 KNX 系统。不断出现的堆栈跟踪是这样的：

有些东西是“无效的论点”，但我不明白可能是什么问题。下面的代码是我使用的：它基于 Springboot，我通过 application.yaml 配置连接。这些值（在本例中只有一个）被映射到 KnxProperties 对象中，我进一步使用它来设置 KNXNetworkLinx bean。

application.yaml

knx:
  connection:
    remoteAddress: 10.0.1.223

@Configuration
@ConfigurationProperties(prefix = "knx")
@Getter @Setter
public class KnxProperties {

    private Connection connection;

    @Configuration
    @Getter @Setter
    public static class Connection {

        private String remoteAddress;
        
        private Integer remotePort = 3671;
        
        private String localAddress = null;
        
        private Integer localPort = 0;
        
    }
    
}
