springboot输出json格式日志
1、在pom文件中添加依赖
<dependency>
<groupId>net.logstash.logback</groupId>
<artifactId>logstash-logback-encoder</artifactId>
<version>6.2</version>
</dependency>2、创建logback-spring.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<!--
说明：
1. 文件的命名和加载顺序有关
logback.xml早于application.yml加载，logback-spring.xml晚于application.yml加载
如果logback配置需要使用application.yml中的属性，需要命名为logback-spring.xml
2. logback使用application.yml中的属性
使用springProperty才可使用application.yml中的值 可以设置默认值
