logback自定义日志文件

一、自定义文件路径

1、application.yml

添加配置

spring:
  application:
    name: test
    
logging:
  config:
    path: logs/${spring.application.name}

2、logback-spring.xml

添加配置

<springProperty scop="Context" name="LOG_PATH" source="logging.config.path" defaultValue=""/>
<property name="log.path" value="${LOG_PATH}" />

<appender name="debug" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${log.path}/debug.log</file>
		...
</appender>

二、自定义日志输出格式

要求dubug日志文件中日志格式为：
Date:yyyy-MM-dd HH:mm:ss level:级别 thread:线程ID host:主机标示 client:客户端标示 url:请求url type1:自定义类型1 type2:自定义类型2 type3:自定义类型3 msg:自定义消息

1、ApplicationConfig.java

import ch.qos.logback.classic.helpers.MDCInsertingServletFilter;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;

import javax.servlet.Filter;
import java.util.ArrayList;
import java.util.List;

@Component
public class ApplicationConfig {
    @Bean
    public FilterRegistrationBean filterRegistrationBean() {
        FilterRegistrationBean registrationBean = new FilterRegistrationBean();
        Filter actionFilter = new MDCInsertingServletFilter();
        registrationBean.setFilter(actionFilter);
        List<String> urlPatterns = new ArrayList<>();
        urlPatterns.add("/*");
        registrationBean.setUrlPatterns(urlPatterns);
        return registrationBean;
    }
}

2、IPLogConfig.java

• 用于获取主机IP

import ch.qos.logback.classic.pattern.ClassicConverter;
import ch.qos.logback.classic.spi.ILoggingEvent;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.net.InetAddress;
import java.net.UnknownHostException;

public class IPLogConfig extends ClassicConverter {
    private static final Logger logger = LoggerFactory.getLogger(IPLogConfig .class);
    private static String webIP;
    static {
        try {
            webIP = InetAddress.getLocalHost().getHostAddress();
        } catch (UnknownHostException e) {
            logger.error("获取日志Ip异常", e);
            webIP = null;
        }
    }

    @Override
    public String convert(ILoggingEvent event) {
        return webIP;
    }
}

3、logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false" scan="false">
    <springProperty scop="context" name="spring.application.name" source="spring.application.name" defaultValue=""/>
    <property name="log.path" value="logs/${spring.application.name}"/>

    <conversionRule conversionWord="ip" converterClass="com.cn.jf.config.IPLogConfig" />

    <!-- 彩色日志格式 11-->
    <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}}"/>

    <!-- 彩色日志依赖的渲染类 -->
