SpringBoot2.X中lagback详细配置及使用

一、前言

Spring Boot默认集成了Logback，可以开箱即用，非常方便。因为spring-boot-starter-logging是Logback的日志实现，而Spring Boot启动项spring-boot-starter又依赖了spring-boot-starter-logging，所以Spring Boot就默认集成了Logback.

二、自定义日志配置

1.约束

日志服务在ApplicationContext创建前就初始化了，所以通过设置属性和传统的配置XML文件，可以对日志进行管理和控制。只需要在src/main/resources下，创建好约定名称的XML文件，即可完成对日志系统的设置，不同的日志系统有不同的约定名称。

日志系统	配置文件名称
logback	logback-spring.xml, logback-spring.groovy, logback.xml, 或者 logback.groovy
log4j2	log4j2-spring.xml 或者 log4j2.xml

Spring Boot官方建议使用“-spring”的命名规则，进行日志配置，如：logback-spring.xml而不是logback.xml。

2.自定义

在配置文件中指定即可

# 日志
logging:
  config: classpath:log/logback-dev.xml

三、详细配置

    <contextName>logbackcontextName>
    
    
    <property name="log.path" value="/home/huitian/fgap/logs" />

    <conversionRule conversionWord="wEx" converterClass="org.springframework.boot.logging.logback.ExtendedWhitespaceThrowableProxyConverter" />
    
    <property name="CONSOLE_LOG_PATTERN" value="${CONSOLE_LOG_PATTERN:-%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(:){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}}"/>

四、使用

1. 类方式

package com.dingwen.lir.controller;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

/**
 * log 测试
 *
 * @author dingwen
 * 2021.05.07 11:01
 */
public class LogController {
     
    private final Logger logger = LoggerFactory.getLogger(this.getClass());

    public void test() {
     
        int index = 0;
        logger.info("index={}", index);
    }
}

2.注解方式

需要安装lombok 插件

package com.dingwen.lir.controller;

import lombok.extern.slf4j.Slf4j;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

/**
 * log 测试
 *
 * @author dingwen
 * 2021.05.07 11:01
 */
@Slf4j
public class LogController {
     
    public void test() {
     
        int index = 0;
        log.info("index={}", index);
    }
}

五、Mybatis log 插件

可以直接根据参数拼接出可以直接执行的SQL语句，方便排错。
