Spring Cloud Sleuth 整合 Zipkin

偏执的太偏执、 2022-05-25 03:43 305阅读 0赞

**Spring Cloud Sleuth 是分布式服务跟踪，Zipkin可以帮助收集时间数据，解决在microservice架构下的延迟问题。**

添加 **@EnableZipkinServer**

@EnableZipkinServer
    @EnableEurekaClient
    @SpringBootApplication
    public class ServerZipkinApplication { 
    
        public static void main(String[] args) {
            SpringApplication.run(ServerZipkinApplication.class, args);
        }
    }

**zipkin server 默认将跟踪信息存储在内存中,每次重启都会丢失之前的跟踪信息,可以修改为mysql存储**

application.yml

# 修改为mysql存储:
    # 1.添加依赖 <dependency>
    # <groupId>org.springframework.boot</groupId>
    # <artifactId>spring-boot-starter-jdbc</artifactId>
    # </dependency>
    # <dependency>
    # <groupId>mysql</groupId>
    # <artifactId>mysql-connector-java</artifactId>
    # </dependency>
    # <dependency>
    # <groupId>io.zipkin.java</groupId>
    # <artifactId>zipkin-autoconfigure-storage-mysql</artifactId>
    # </dependency>
    #
    # 2.配置 spring.datasource
    # 3.配置 zipkin.storage.type=mysql
    spring:
      datasource:
    # zipkin-autoconfigure-storage-mysql 包下有 mysql.sql 脚本,程序启动时会自动根据sql脚本创建表结构
        schema: classpath:/mysql.sql
        url: jdbc:mysql://localhost:3306/qinwei?useUnicode=true&characterEncoding=utf-8
        username: root
        password: 123456
        initialize: true

application.properties

server.port=8090
    spring.application.name=server-zipkin
    eureka.client.service-url.defaultZone=http://localhost:8081/eureka-server/eureka/
    management.security.enabled=false
    #将zipkin server 存储切换为 mysql
    zipkin.storage.type=mysql

在需要跟踪的服务中添加依赖

<dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-zipkin</artifactId>
            </dependency>

**在配置文件中指定Zipkin Server的地址**

application.properties

spring.zipkin.base-url=http://localhost:8090

创建 bean

@Bean
        public RestTemplate getRestTemplate() {
            return new RestTemplate();
        }
    
        /** * sleuth 默认使用 PercentageBasedSampler 实现的抽样策略,以请求百分比的方式配置和收集跟踪信息. * 默认是0.1(表示收集10%的跟踪信息),可以配置spring.sleuth.sampler.percentage来修改. * <p> * 创建 AlwaysSampler 的bean,会覆盖默认的 PercentageBasedSampler 策略,收集全部的跟踪信息 */
        @Bean
        public AlwaysSampler defaultSampler() {
            return new AlwaysSampler();
        }
