ELK整合springboot(第二课)

一、创建一个springboot的项目

在这里插入图片描述
pom文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.7.13</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.tuling</groupId><artifactId>elk-demo</artifactId><version>0.0.1-SNAPSHOT</version><name>elk-demo</name><description>elk-demo</description><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><dependency><groupId>net.logstash.logback</groupId><artifactId>logstash-logback-encoder</artifactId><version>5.3</version></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

创建一个最简单的控制层，输出日志
在这里插入图片描述
修改application.properties默认配置，给这个项目起个名字

创建logback-spring.xml文件，修改destination这个改成自己的服务器地址，端口是logstash同步es的端口，可以看第一节课

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false"><!--提取配置文件中的服务名--><springProperty scope="context" name="springApplicationName" source="spring.application.name" /><property name="LOG_HOME" value="logs/demo.log" /><appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"><encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"><pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern></encoder></appender><appender name="logstash" class="net.logstash.logback.appender.LogstashTcpSocketAppender"><filter class="ch.qos.logback.classic.filter.ThresholdFilter"><level>INFO</level></filter><destination>192.168.85.200:4560</destination><encoder charset="UTF-8" class="net.logstash.logback.encoder.LoggingEventCompositeJsonEncoder"><providers><timestamp><timeZone>Asia/Shanghai</timeZone></timestamp><!--自定义日志输出格式--><pattern><pattern>{"project": "elk","level": "%level","service": "${springApplicationName:-}","pid": "${PID:-}","thread": "%thread","class": "%logger","message": "%message","stack_trace": "%exception"}</pattern></pattern></providers></encoder></appender><root level="INFO"><appender-ref ref="STDOUT" /><appender-ref ref="logstash" /></root>
</configuration>
