前言

网关层作为我们程序的主入口，有着至关重要的作用，下面我们通过自定义Logback配置增强网关层的日志输出，为我们的网关提供更加详细和更加细化的日志输出。

大家有没有好奇过一件事，为什么我们的Spring Boot项目新建完，日志组件就能刷刷地打印呢？这是因为Spring Boot帮助我们集成了Logback并定义了默认的logger和appender，接下来我们来进行详细的解析。

一、内置配置

1. 关联依赖

spring-boot-starter-web>spring-boot-starter>spring-boot-starter-logging>logback-classic>logback-core

2. 内置配置

base.xml：定义了基本配置和引入其他配置文件
defaults.xml：定义了彩色日志，日志变量和日志logger
console-appender.xml：定义了控制台输出appender
file-appender.xml：定义了文件输出appender

二、自定义配置

我们自定义配置生效后，Spring Boot内置配置就不再生效，大家要知道这点
设计思路：

• debug.log(存储debug及高级别日志)
• info.log(存储info及高级别日志)
• error.log(存储error及高级别日志)

1. 日志级别

我们只关注三个常用的:DEBUG、INFO、ERROR即可

TRACE<DEBUG<INFO<WARN<ERROR<FATAL

2. 彩色日志

颜色

• blue
• cyan
• green
• magenta
• red
• yellow

样式

• bold（粗体）
• faint（淡色）
• highlight（高亮）

3. 自定义配置

<?xml version="1.0" encoding="UTF-8"?>
<configuration><!-- 引入Spring Boot的默认logback配置 --><property name="CONSOLE_PATTERN" value="${CONSOLE_LOG_PATTERN:-%clr(%d{${LOG_DATEFORMAT_PATTERN:-yyyy-MM-dd HH:mm:ss.SSS}}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(%applicationName[%15.15t]){faint} %clr(${LOG_CORRELATION_PATTERN:-}){faint}%clr(%-40.40logger{39}:%L) %clr(:){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}}"/><property name="FILE_PATTERN" value="${FILE_LOG_PATTERN:-%d{${LOG_DATEFORMAT_PATTERN:-yyyy-MM-dd HH:mm:ss.SSS}} ${LOG_LEVEL_PATTERN:-%5p} ${PID:- } %applicationName[%t] ${LOG_CORRELATION_PATTERN:-}%-40.40logger{39}:%L : %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}}"/><include resource="org/springframework/boot/logging/logback/defaults.xml"/><!-- 自定义控制台输出模板 --><property name="LOG_HOME" value="../logs/gateway/"/><property name="LOG_FILE" value="gateway"/><property name="LOGBACK_ROLLINGPOLICY_CLEAN_HISTORY_ON_START" value="false"/><property name="LOGBACK_ROLLINGPOLICY_MAX_FILE_SIZE" value="10MB"/><property name="LOGBACK_ROLLINGPOLICY_TOTAL_SIZE_CAP" value="0"/><property name="LOGBACK_ROLLINGPOLICY_MAX_HISTORY" value="7"/><appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender"><filter class="ch.qos.logback.classic.filter.ThresholdFilter"><level>${CONSOLE_LOG_THRESHOLD}</level></filter><encoder><pattern>${CONSOLE_PATTERN}</pattern><charset>${CONSOLE_LOG_CHARSET}</charset></encoder></appender><appender name="DEBUG_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"><filter class="ch.qos.logback.classic.filter.ThresholdFilter"><level>DEBUG</level></filter><encoder><pattern>${FILE_PATTERN}</pattern><charset>${FILE_LOG_CHARSET}</charset></encoder><file>${LOG_HOME}${LOG_FILE}_debug.log</file><!--大小和时间基于滚动策略--><rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy"><fileNamePattern>${LOG_HOME}${LOG_FILE}_debug.%d{yyyy-MM-dd}.%i.gz</fileNamePattern><cleanHistoryOnStart>${LOGBACK_ROLLINGPOLICY_CLEAN_HISTORY_ON_START:-false}</cleanHistoryOnStart><maxFileSize>${LOGBACK_ROLLINGPOLICY_MAX_FILE_SIZE:-10MB}</maxFileSize><totalSizeCap>${LOGBACK_ROLLINGPOLICY_TOTAL_SIZE_CAP:-0}</totalSizeCap><maxHistory>${LOGBACK_ROLLINGPOLICY_MAX_HISTORY:-7}</maxHistory></rollingPolicy></appender><appender name="INFO_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"><filter class="ch.qos.logback.classic.filter.ThresholdFilter"><level>INFO</level></filter><encoder><pattern>${FILE_PATTERN}</pattern><charset>${FILE_LOG_CHARSET}</charset></encoder><file>${LOG_HOME}${LOG_FILE}_info.log</file><!--大小和时间基于滚动策略--><rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy"><fileNamePattern>${LOG_HOME}${LOG_FILE}_info.%d{yyyy-MM-dd}.%i.gz</fileNamePattern><cleanHistoryOnStart>${LOGBACK_ROLLINGPOLICY_CLEAN_HISTORY_ON_START:-false}</cleanHistoryOnStart><maxFileSize>${LOGBACK_ROLLINGPOLICY_MAX_FILE_SIZE:-10MB}</maxFileSize><totalSizeCap>${LOGBACK_ROLLINGPOLICY_TOTAL_SIZE_CAP:-0}</totalSizeCap><maxHistory>${LOGBACK_ROLLINGPOLICY_MAX_HISTORY:-7}</maxHistory></rollingPolicy></appender><appender name="ERROR_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"><filter class="ch.qos.logback.classic.filter.ThresholdFilter"><level>ERROR</level></filter><encoder><pattern>${FILE_PATTERN}</pattern><charset>${FILE_LOG_CHARSET}</charset></encoder><file>${LOG_HOME}${LOG_FILE}_error.log</file><!--大小和时间基于滚动策略--><rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy"><fileNamePattern>${LOG_HOME}${LOG_FILE}_error.%d{yyyy-MM-dd}.%i.gz</fileNamePattern><cleanHistoryOnStart>${LOGBACK_ROLLINGPOLICY_CLEAN_HISTORY_ON_START:-false}</cleanHistoryOnStart><maxFileSize>${LOGBACK_ROLLINGPOLICY_MAX_FILE_SIZE:-10MB}</maxFileSize><totalSizeCap>${LOGBACK_ROLLINGPOLICY_TOTAL_SIZE_CAP:-0}</totalSizeCap><maxHistory>${LOGBACK_ROLLINGPOLICY_MAX_HISTORY:-7}</maxHistory></rollingPolicy></appender><!-- 设置特定包的日志级别 --><logger name="org.springframework" level="INFO"/><logger name="org.hibernate" level="INFO"/><logger name="com.alibaba" level="INFO"/><logger name="io.netty" level="INFO"/><logger name="reactor.netty" level="INFO"/><!-- Root Logger --><root level="DEBUG"><appender-ref ref="CONSOLE"/><appender-ref ref="DEBUG_FILE"/><appender-ref ref="INFO_FILE"/><appender-ref ref="ERROR_FILE"/></root>
</configuration>

4. 增加打印语句

package org.example.gateway.config;import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;/*** Create by zjg on 2024/8/3*/
@Component
public class GatewayApplicationAware implements ApplicationContextAware {Logger logger = LoggerFactory.getLogger(GatewayApplicationAware.class);@Overridepublic void setApplicationContext(ApplicationContext applicationContext) throws BeansException {logger.debug("Debug log message");logger.info("Info log message");logger.error("Error log message");}
}

5. 效果展示

有了详细的日志文件记录，我们就再也不怕程序报错了，加油，奥利给！
