SpringBoot日志输出至Logstash

1.springboot项目pom.xml文件下添加如下配置

2.resources目录下创建logback-spring.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!--该日志将日志级别不同的log信息保存到不同的文件中 -->
<configuration>
    <include resource="org/springframework/boot/logging/logback/defaults.xml"/>

    <springProperty scope="context" name="springAppName"
                    source="spring.application.name"/>

    <!-- 日志在工程中的输出位置 -->
    <property name="LOG_FILE" value="${BUILD_FOLDER:-build}/${springAppName}"/>

    <!-- 控制台的日志输出样式 -->
    <property name="CONSOLE_LOG_PATTERN"
              value="%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(---){faint} %clr([%15.15t]){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}}"/>

    <!-- 控制台输出 -->
