Lombok cooperates with @slf4j and logback to realize logging

Lombok coordination @Slf4j、Logback Implement logging

Development process , Need to use lombok, But sometimes it is not used SpringBoot frame , Therefore, the log is not automatically imported Jar, Need to be on your own maven Introduction in .

<dependency>
   <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.20</version>
</dependency>

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.32</version>
</dependency>

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-core</artifactId>
    <version>1.2.6</version>
</dependency>

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.2.6</version>
</dependency>

Introduce the above jar package , And in resources Create below logback.xml

<?xml version="1.0" encoding="UTF-8" ?>
<configuration>
　　　<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
　　　　　 <encoder>
　　　　　　　　　<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
　　　　　 </encoder>
　　　</appender>

　　　<root level="DEBUG">
　　　　　　<appender-ref ref="CONSOLE" />
　　　</root>
</configuration>

Can be introduced in the class @Slf4j

test

package com.plf.agent;

import lombok.extern.slf4j.Slf4j;

/**
 * @author panlf
 * @date 2021/11/10
 */
@Slf4j
public class HelloWorld {
    public static void main(String[] args) {
        log.info("Hello World");
    }
}

// result 
//2021-11-10 16:16:09.092 [main] INFO  com.plf.agent.HelloWorld - Hello World
