SpringBoot logback 配置文件自定义属性

添加自定义属性类

package com.cus.config;

import ch.qos.logback.core.PropertyDefinerBase;
import org.springframework.stereotype.Component;

import java.net.InetAddress;
import java.text.SimpleDateFormat;
import java.util.Date;

@Component
public class CustomProperty extends PropertyDefinerBase {

    @Override
    public String getPropertyValue() {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmssSSS");
        String str = sdf.format(new Date());
        try{
            InetAddress address = InetAddress.getLocalHost();
            str = address.getHostAddress() + "_" + str;
        }
        catch (Exception e){
            e.printStackTrace();
        }

        return str;
    }
}

在 logback.xml 中使用自定义属性

定义属性：

<define name="port" class="com.cus.config.CustomProperty" />

使用定义的属性：

${port}

<file>${LOG_HOME}/info_${port}.log</file>

    <property name="LOG_HOME" value="${LOG_FILE:-${LOG_PATH:-${LOG_TEMP:-${java.io.tmpdir:-./tmp}}/}}"/>
    <!-- 最大保存历史日志天数 -->
