#### 一、现象说明 ####

最近在调试 RabbitMQ 程序的时候，日志里如下错误：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
    SLF4J: Defaulting to no-operation (NOP) logger implementation
    SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

RabbitMQ 发送消息\_程序代码如下：

package com.miracle.luna.rabbitmq;
    
    import com.rabbitmq.client.Channel;
    import com.rabbitmq.client.Connection;
    import com.rabbitmq.client.ConnectionFactory;
    
    import java.nio.charset.StandardCharsets;
    
    /**
     * @author Miracle Luna
     * @date 2021/10/19
     */
    public class SendMQ {
        
        private final static String QUEUE_NAME = "hello";
    
        public static void main(String[] args) throws Exception{
        
            ConnectionFactory factory = new ConnectionFactory();
            factory.setHost("localhost");
            factory.setPort(5672);
            factory.setUsername("guest");
            factory.setPassword("guest");
    
            final Connection connection = factory.newConnection();
            final Channel channel = connection.createChannel();
            channel.queueDeclare(QUEUE_NAME, false, false, false, null);
    
            String message = "Hello, RabbitMQ!";
            channel.basicPublish("", QUEUE_NAME, null, message.getBytes(StandardCharsets.UTF_8));
            System.out.println("Send '" + message + "'");
    
            channel.close();
            connection.close();
        }
    }

#### 二、解决方案 ####

在pom文件中增加 **slf4j-simple** 的依赖，并 **Reload project**，如下：

<dependency>
       <groupId>org.slf4j</groupId>
       <artifactId>slf4j-simple</artifactId>
       <version>1.7.32</version>
       <scope>compile</scope>
    </dependency>

> （注意本地调试的时候，pom引用里 scope的值是“compile”，而非“test”！！！）

再次运行程序，就不会有报错日志了，效果如下：
