概述

    SpringBoot整合ELK单指将SpringBoot日志推送至Logstash以及使用教程。

日志流程

    项目输出Log日志  --> TCP推送Logstash  -->  Logstash接收日志处理  -->  输出到Elasticsearch中  -->  Kibana图形化展示

    流程图如下：

Logstash配置

TCP方式

input {
        # TCP输入，Json格式编码UTF-8
    tcp {
     port => 9400
      codec => json {
             charset => "UTF-8"
      }
    }
    stdin{}
}
filter {
}

output {
  elasticsearch {
    action => "index"
    # 这里是es的地址，多个es要写成数组的形式
    hosts  => "elasticsearch-server:9200"
    # 用于kibana过滤，可以填项目名称，按日期生成索引
    index  => "vosp-log-%{+YYYY-MM-dd}"
    # es用户名
    user => vosp
    # es密码
    password => vosp123
    # 超时时间
    timeout => 300
  }
}

SpringBoot+Log4j2

编写SpringBoot启动以及配置类

    新建配置类,

import org.slf4j.MDC;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.context.event.ApplicationEnvironmentPreparedEvent;
import org.springframework.boot.context.event.ApplicationFailedEvent;
import org.springframework.boot.context.event.ApplicationPreparedEvent;
import org.springframework.boot.context.event.ApplicationStartingEvent;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationEvent;
import org.springframework.context.event.ContextClosedEvent;
import org.springframework.context.event.GenericApplicationListener;
import org.springframework.core.Ordered;
import org.springframework.core.ResolvableType;
import org.springframework.core.env.ConfigurableEnvironment;
import org.springframework.core.env.MutablePropertySources;
import org.springframework.core.env.PropertySource;


/**

 * 启动类启动注册监听器
 */
public class Log4j2PropertiesEventListener implements GenericApplicationListener {

    public static final int DEFAULT_ORDER = Ordered.HIGHEST_PRECEDENCE + 10;

    private static Class<?>[] EVENT_TYPES = {ApplicationStartingEvent.class, ApplicationEnvironmentPreparedEvent.class,
            ApplicationPreparedEvent.class, ContextClosedEvent.class, ApplicationFailedEvent.class};

    private static Class<?>[] SOURCE_TYPES = {SpringApplication.class, ApplicationContext.class};

    @Override
    public void onApplicationEvent(ApplicationEvent event) {
        if (event instanceof ApplicationEnvironmentPreparedEvent) {
            ConfigurableEnvironment envi = ((ApplicationEnvironmentPreparedEvent) event).getEnvironment();
            MutablePropertySources mps = envi.getPropertySources();
            // 获取配置文件配置源,注意版本不同SpringBoot可能配置源名称不一样，可以DEBUG查看名称
            PropertySource<?> ps = mps.get("configurationProperties");

            if (ps != null && ps.containsProperty("log4j2.logstash.address")) {
                Object address = ps.getProperty("log4j2.logstash.address");
                if (address != null && !address.toString().trim().isEmpty()) {
                    MDC.put("log4j2.logstash.address", address.toString());
                }
            }
            // 设置log4j2日志收集logstash端口号
            if (ps != null && ps.containsProperty("log4j2.logstash.port")) {
                Object port = ps.getProperty("log4j2.logstash.port");
                if (port != null && !port.toString().trim().isEmpty()) {
                    MDC.put("log4j2.logstash.port", port.toString());
                }
            }
            // 设置log4j2日志收集logstash日志格式化表达式
            if (ps != null && ps.containsProperty("log4j2.logstash.pattern")) {
                Object pattern = ps.getProperty("log4j2.logstash.pattern");
                if (pattern != null && !pattern.toString().trim().isEmpty()) {
                    // 获取项目名
                    String appName = ps.getProperty("spring.application.name").toString();
                    // 获取项目名
                    String profile = ps.getProperty("spring.profiles.active").toString();
                    MDC.put("log4j2.logstash.pattern", pattern.toString().replace("${spring.application.name}", appName).replace("${spring.profiles.active}",profile));
                }
            }

        }
    }

    @Override
    public int getOrder() {
        return DEFAULT_ORDER;
    }

    @Override
    public boolean supportsEventType(ResolvableType resolvableType) {
        return isAssignableFrom(resolvableType.getRawClass(), EVENT_TYPES);
    }

    @Override
    public boolean supportsSourceType(Class<?> sourceType) {
        return isAssignableFrom(sourceType, SOURCE_TYPES);
    }

    private boolean isAssignableFrom(Class<?> type, Class<?>... supportedTypes) {
        if (type != null) {
            for (Class<?> supportedType : supportedTypes) {
                if (supportedType.isAssignableFrom(type)) {
                    return true;
                }
            }
        }
        return false;
    }
}

    修改SpringBoot启动类，添加监听器

    public static void main(String[] args) {
        SpringApplication application = new SpringApplication(BootK8sApplication.class);
        // 添加Log4j2配置文件监听
        Log4j2PropertiesEventListener eventListener = new Log4j2PropertiesEventListener();
        application.addListeners(eventListener);
        application.run(args);
    }       

编写配置文件

    在Yaml中写入如下参数

spring:
  application:
    # 项目名称启动时传入Log4j2作为app名称
    name: test-k8s

logging:
  # Log4j2配置文件xml地址
  config: classpath:log4j2-spring.xml
log4j2:
  logstash:
    # 自定义配置Logstash地址
    address: 124.71.9.101
    # 自定义配置Logstash端口号
    port: 9400
    # 自定义Json消息
    # {
        #   "app": "${spring.application.name}",  当前项目名称
        #   "class": "%c",                        类全限定名称
        #   "method": "%M",                       输出日志方法
        #   "traceId": "%X{traceId}",             traceId跟踪
        #   "level": "%level",                    日志级别
        #   "message": "[%thread] [%c:%L] --- %replace{%msg}{\"}{\\\"}\"  消息内容体，将"替换为转义，防止日志中输出Json导致解析异常
        #   "profile":"${spring.profiles.active}" 当前启动环境
    # }
    # Json写入至ELK中属性
    pattern: "{\"app\":\"${spring.application.name}\", \"profile\":\"${spring.profiles.active}\", \"class\":\"%c\",\"method\":\"%M\",\"traceId\":\"%X{traceId}\",\"level\": \"%level\", \"message\": \"[%thread] [%c:%L] --- %replace{%msg}{\\\"}{\\\\\\\"}\\\"}%n"

编写Log4j2-XML文件

新增traceId拦截器

    新建拦截器

import org.slf4j.MDC;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.HandlerInterceptor;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.UUID;

/**
 * @Author HuangKang
 * @Date 2021/4/23 下午2:23
 * @Summarize 请求TraceId拦截器
 */
@Component
public class RequestTraceIdInterceptor implements HandlerInterceptor {
    /**
     * 日志TRACE_ID名称常量
     */
    private static final String LOG_TRACE_ID_NAME = "traceId";

    /**
     *
     * @param request
     * @param response
     * @param handler
     * @return
     * @throws Exception
     */
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        MDC.put(LOG_TRACE_ID_NAME, UUID.randomUUID().toString().replace("-",""));
        return true;
    }

}

    新增Mvc配置拦截器

package com.kang.test.k8s.config;

import com.kang.test.k8s.interceptor.RequestTraceIdInterceptor;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

/**
 * @Author HuangKang
 * @Date 2021/4/23 下午4:00
 * @Summarize 自定义WebMvc配置
 */
@Configuration
public class CustomWebMvcConfig  implements WebMvcConfigurer {

    final RequestTraceIdInterceptor requestTraceIdInterceptor;

    @Autowired
    public CustomWebMvcConfig(RequestTraceIdInterceptor requestTraceIdInterceptor) {
        this.requestTraceIdInterceptor = requestTraceIdInterceptor;
    }

    /**
     * 添加拦截器
     * @param registry
     */
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        // 添加TraceId拦截器
        registry.addInterceptor(requestTraceIdInterceptor);
    }
}

    使用方式，新建Controller测试功能

    @RequestMapping("/")
    public Map index() throws UnknownHostException {
        Map<String, Object> map = new HashMap<>();
        InetAddress localHost = InetAddress.getLocalHost();
        String hostName = localHost.getHostName();
        String hostAddress = localHost.getHostAddress();
        map.put("主机名",hostName);
        map.put("主机地址",hostAddress);
        log.info("测试日志");
        return map;
    }

    调用接口后打印如下日志

可以查看到INFO  [3d9e051ceafe4e59bce8aa6ac2972fda] 成功打印traceId
2021-04-23 16:21:13,929 INFO  [3d9e051ceafe4e59bce8aa6ac2972fda] [http-nio-8080-exec-1] [c.k.t.k.c.TestK8sController:37] 测试日志

SpringBoot+Logback

引入依赖

    引入依赖正常即可

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>

        </dependency>

        <dependency>

            <artifactId>logstash-logback-encoder</artifactId>
            <version>6.1</version>
        </dependency>

编写配置文件

spring:
  application:
    # 项目名称启动时传入，写入ELK通过app名称进行隔离
    name: test-k8s
  profiles:
    # 启动环境，ELK隔离通过profile属性隔离dev以及prod
    active: log
server:
  port: 8080
logging:
    # 日志文件地址
  config: classpath:logback-spring.xml
  # 配置Logstash地址
  logstash:
    address: 124.71.9.101:9400

编写XML文件

    新建XML文件，重点观察ELK Json属性，可以自定义拓展,新建logback-spring.xml
