如何调试spring-framework类中的特定语句？

Question

我希望spring只记录以下代码行：

this.logger.debug("New connection " + this.getConnectionId());

因此，我在application.properties中添加了以下配置：logging.level.org.springframework.integration.ip.tcp.connection.TcpNioConnection=DEBUG

这可以很好地工作，但当然它会记录该类中的所有logger.debug()语句。

问:是否可以只记录所需的语句？

解决了监听套接字事件的问题：

@Component
public class SocketListener {
    private final Logger LOGGER = LoggerFactory.getLogger(this.getClass());

    @EventListener
    public void onTcpConnectionOpenEvent(TcpConnectionOpenEvent event) {
        LOGGER.info("new con " + event.getConnectionId());
    }

    @EventListener
    public void onTcpConnectionCloseEvent(TcpConnectionCloseEvent event) {
        LOGGER.info("con closed " + event.getConnectionId());
    }

    @EventListener
    public void onTcpConnectionOpenEvent(TcpConnectionExceptionEvent event) {
        LOGGER. error("con error " + event.getConnectionId());
    }
}
