这篇文章主要为大家详细介绍了SpringBoot整合ELK实现日志监控的相关知识,文中的示例代码讲解详细,感兴趣的小伙伴可以跟随小编一起学习一下

ELK 安装汇总

可参考一下安装内容，过程亲测可用。

CentOS下安装Kibana（保姆级教程）

CentOS下安装ElasticSearch7.9.2（无坑版）

Logstash 安装与部署（无坑版）

新建SpringBoot项目

pom依赖

新建或修改application.yml

这个操作随意，可以不改端口号

server:
  port: 8088

创建日志配置文件

在项目的 resources 目录下创建 logback-spring.xml 文件，也就是日志输出配置文件SpringBoot默认的使用的logback日志，必须叫这个名字！！！

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration>
<configuration>
    <include resource="org/springframework/boot/logging/logback/defaults.xml"/>
    <include resource="org/springframework/boot/logging/logback/console-appender.xml"/>
    <!--应用名称-->
    <property name="APP_NAME" value="logstash"/>
    <!--日志文件保存路径-->
    <property name="LOG_FILE_PATH" value="${LOG_FILE:-${LOG_PATH:-${LOG_TEMP:-${java.io.tmpdir:-/tmp}}}/logs}"/>
    <contextName>${APP_NAME}</contextName>
    <!--每天记录日志到文件appender-->
    <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${LOG_FILE_PATH}/${APP_NAME}-%d{yyyy-MM-dd}.log</fileNamePattern>
            <maxHistory>30</maxHistory>
        </rollingPolicy>
        <encoder>
            <pattern>${FILE_LOG_PATTERN}</pattern>
        </encoder>
    </appender>
    <!--输出到logstash的appender-->
    <appender name="LOGSTASH" class="net.logstash.logback.appender.LogstashTcpSocketAppender">
        <!--可以访问的logstash日志收集的ip和端口-->
        <destination>你的ip:端口号</destination>
        <encoder charset="UTF-8" class="net.logstash.logback.encoder.LogstashEncoder"/>
    </appender>
    <root level="INFO">
        <appender-ref ref="CONSOLE"/>
        <appender-ref ref="FILE"/>
        <appender-ref ref="LOGSTASH"/>
    </root>
</configuration>

创建一个测试类

package com.example.demo.controller;

import lombok.extern.slf4j.Slf4j;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@Slf4j
public class HelloController {
    
//    private static final Logger logger = LoggerFactory.getLogger(HelloController.class);
    
    @GetMapping("/hello")
    public String hello() {
        log.warn("HelloController执行-----log.warn");
        log.info("HelloController执行-----log.info");
        log.error("HelloController执行-----log.error");
//        logger.info("HelloController执行hello");
        return "hello";
    }
}
