spring boot 日志配置文件 获取application.yml 配置

logback

新建logback-spring.xml

    <springProperty scope="context" name="application" source="spring.application.name"/>
    <springProperty scope="context" name="project" source="dynamic.base.package"/>

source 表示的是application.yml 里面的配置key

log4j2

没有找到直接配置，只能对spring 初始化监听器的自定义实现，然后利用mdc设置参数，供日志配置文件调用

package com.nfsq.terminal.config.listener;

import org.slf4j.MDC;
import org.springframework.boot.context.event.ApplicationEnvironmentPreparedEvent;
import org.springframework.context.ApplicationListener;
import org.springframework.core.Ordered;
import org.springframework.core.env.ConfigurableEnvironment;
import org.springframework.core.env.MutablePropertySources;
import org.springframework.core.env.PropertySource;

/**
 * 自定义spring boot 监听器为log4j2 获取自定义上下文
 * 必须实现Ordered，启动顺序可以提到创建日志文件之前
 * 
 * 
 * 
 * <p>
 * ApplicationStartingEvent：           spring boot启动开始时执行的事件
 * <p>
 * ApplicationEnvironmentPreparedEvent：spring boot 对应Enviroment已经准备完毕，但此时上下文context还没有创建
 * <p>
 * ApplicationPreparedEvent:            spring boot上下文context创建完成，但此时spring中的bean是没有完全加载完成的
 * <p>
 * ApplicationFailedEvent:              spring boot启动异常时执行事件

public class MyApplicationStartedEventListener implements ApplicationListener<ApplicationEnvironmentPreparedEvent>, Ordered {


    @Override
    public void onApplicationEvent(ApplicationEnvironmentPreparedEvent event) {

        ConfigurableEnvironment configurableEnvironment = event.getEnvironment();

        MutablePropertySources mutablePropertySources = configurableEnvironment.getPropertySources();

        PropertySource<?> propertySource = mutablePropertySources.get("applicationConfigurationProperties");

        if (propertySource != null && propertySource.containsProperty("logging.runtime.root")) {

            String rootDir = (String) propertySource.getProperty("root.dir");


            String runTimeCountPath = ((String) propertySource.getProperty("logging.runtime.root")).replace("${root.dir}", rootDir);
            System.out.println("*******************************");
            System.out.println(runTimeCountPath);
            System.out.println("*******************************");
            MDC.put("runTimeCountPath", runTimeCountPath);

        }


    }

    @Override
    public int getOrder() {
        return Ordered.HIGHEST_PRECEDENCE + 10;
    }
}

然后在启动类中调用：

package com.nfsq.terminal;

import com.alibaba.dubbo.spring.boot.annotation.EnableDubboConfiguration;
import com.nfsq.terminal.config.listener.ApplicationStartedEventListener;
import com.nfsq.terminal.config.listener.MyApplicationStartedEventListener;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@EnableDubboConfiguration
public class EndeavourApplication {

    public static void main(String[] args) {

        SpringApplication app = new SpringApplication(EndeavourApplication.class);
        app.addListeners(new MyApplicationStartedEventListener());
      //app.addListeners(new ApplicationStartedEventListener());
        app.run(args);
    }
}

log4j2.yml 调用添加ctx

#    AOP监控：统计运行时间
      - name: runTimeCount
        ignoreExceptions: false
        fileName: ${ctx:runTimeCountPath}/endeavour_runTimeCount.log
        filePattern: "${ctx:runTimeCountPath}/endeavour_runTimeCount.log.%d{yyyy-MM-dd}"
        PatternLayout:
          pattern: "%date %-5level [%f:%l] %msg%n%ex"
        Policies:
          TimeBasedTriggeringPolicy:  # 按天分类
            modulate: true
            interval: 1
        DefaultRolloverStrategy:     # 文件最多100个
          max: 100
