网关层作为我们程序的主入口#xff0c;有着至关重要的作用#xff0c;下面我们通过自定义Logback配置增强网关层的日志输出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-webspring-boot-starterspring-boot-starter-logginglogback-classiclogback-core2. 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
TRACEDEBUGINFOWARNERRORFATAL2. 彩色日志

3. 自定义配置
?xml version1.0 encodingUTF-8?

/configuration4. 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);}
}

回到顶部 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
