Spring Cloud 分布式应用跟踪

SpanID:阶段性ID，比如一次RPC有可能多Span
TraceID：一次RPC只有一个TraceID

整合Spring Cloud Sleuth

1.增加依赖

<!-- 整合 Spring Cloud Sleuth -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-sleuth</artifactId>
        </dependency>

Zipkin整合

新增Zipkin服务器
增加Maven依赖

   <!-- Zipkin Server 整合 -->
        <dependency>
            <groupId>io.zipkin.java</groupId>
            <artifactId>zipkin-server</artifactId>
        </dependency>

        <!-- Zipkin Server UI 整合 -->
        <dependency>
            <groupId>io.zipkin.java</groupId>
            <artifactId>zipkin-autoconfigure-ui</artifactId>
        </dependency>

激活Zipkin服务器
HTTP方式采集

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import zipkin.server.EnableZipkinServer;

/**
 * Zipkin 服务器应用
 *
 */
@SpringBootApplication
@EnableZipkinServer
public class ZipkinServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ZipkinServerApplication.class, args);
    }
}

配置Zipkin服务器

## 应用元信息
## Zipkin 服务器应用名称
spring.application.name = zipkin-server

## Zipkin 服务器服务端口
server.port = 20000

## 管理端口安全失效
management.security.enabled = false

整合Zipkin客户端
改造user-service-client
HTTP方式上报
增加Maven依赖

<!-- 整合 Spring Cloud Zipkin -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zipkin</artifactId>
        </dependency>

配置：连接zipkin服务器

## Zipkin 配置
### 配置 Zipkin 服务器
zipkin.server.host = localhost
zipkin.server.port = 20000
spring.zipkin.base-url = http://${zipkin.server.host}:${zipkin.server.port}

改造user-service-provider
增加Maven依赖

 <!-- 整合 Spring Cloud Zipkin -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zipkin</artifactId>
        </dependency>

配置：连接zipkin服务器

## Zipkin 配置
### 配置 Zipkin 服务器
zipkin.server.host = localhost
zipkin.server.port = 20000
spring.zipkin.base-url = http://${zipkin.server.host}:${zipkin.server.port}

改造zipkin服务器：使用Stream方式订阅

增加Maven依赖

 <!-- zipkin 整合 Spring Cloud Sleuth Stream  -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-sleuth-zipkin-stream</artifactId>
        </dependency>

        <!-- 整合 Spring Cloud Stream Binder Rabbit MQ -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-stream-binder-rabbit</artifactId>
        </dependency>

替换激活注解:@EnableZipkinStreamServer
Stream方式采集

package com.segumentfault.spring.cloud.lesson15.zipkin.server;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.sleuth.zipkin.stream.EnableZipkinStreamServer;

/**
 * Zipkin 服务器应用
 *
 */
@SpringBootApplication
//@EnableZipkinServer
@EnableZipkinStreamServer
public class ZipkinServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ZipkinServerApplication.class, args);
    }
}

改造user-service-client

增加Maven依赖
stream方式上报

    <!-- 整合 Spring Cloud Sleuth -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-sleuth</artifactId>
        </dependency> 
        <!-- 整合 Spring Cloud Sleuth Stream -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-sleuth-stream</artifactId>
        </dependency>
        <!-- 整合 Spring Cloud Stream Binder Rabbit MQ -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-stream-binder-rabbit</artifactId>
        </dependency>

注意要移除之前zipkin依赖
