Spring Cloud Sleuth with MySQL

问题描述

我很难找到任何合适的例子来证明我找出痕迹并将其存储在本地的 MysqL 数据库中。 我使用 zipkin 服务器来可视化我对微服务的分布式跟踪。 如果有人在最​​新版本的 gradle 中使用 Spring Cloud Sleuth，请交出可以帮助我的完美示例。

这是我的代码：

build.gradle

plugins {
    id 'org.springframework.boot' version '2.2.6.RELEASE'
    id 'io.spring.dependency-management' version '1.0.9.RELEASE'
    id 'java'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

repositories {
    mavenCentral()
}
ext {
    set('springCloudVersion',"Hoxton.SR4")
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.cloud:spring-cloud-starter-sleuth'
    implementation 'org.springframework.cloud:spring-cloud-sleuth-zipkin'

    compileOnly 'org.projectlombok:lombok'
    annotationProcessor 'org.projectlombok:lombok'
    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage',module: 'junit-vintage-engine'
    }
    implementation group: 'MysqL',name: 'mysql-connector-java',version: '8.0.16'

    // https://mvnrepository.com/artifact/io.zipkin.zipkin2/zipkin-storage-MysqL-v1
    implementation group: 'io.zipkin.zipkin2',name: 'zipkin-storage-MysqL-v1',version: '2.23.2'
    
    // https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-jdbc
    implementation group: 'org.springframework.boot',name: 'spring-boot-starter-jdbc',version: '2.5.0'

}

dependencyManagement {
    imports {
        mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
    }
}

test {
    useJUnitPlatform()
}

application.properties

server.port=8083
spring.application.name=service1
#logging.level.org.springframework.web.servlet.dispatcherServlet=DEBUG
spring.sleuth.sampler.percentage=1.0
spring.zipkin.enabled=true
spring.zipkin.base-url=http://localhost:9411/

spring.datasource.schema=classpath:MysqL.sql
spring.datasource.initialization-mode=always
spring.jpa.show-sql=true
spring.sleuth.web.enabled=true

spring.zipkin.sender.type=web

控制器类

@RestController
@Slf4j
@requiredArgsConstructor
public class SpaceShipRestController {

    private final RestTemplate restTemplate;

    @GetMapping("/service1")
    public String service1() {
        log.info("service1 start");
        String service2 = restTemplate.getForObject("http://localhost:8090/service2",String.class);
        String service3 = restTemplate.getForObject("http://localhost:9090/service3",String.class);
        log.info("call" + service2 + "and" + service3);
        return "calling service2";
    }
}

应用程序类

@SpringBootApplication
@EnableAutoConfiguration
public class DemoApplication {

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

    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }

    @Bean
    @Primary
    public MysqLStorage MysqLStorage(DataSource datasource) {
        return MysqLStorage.newBuilder().datasource(datasource).executor(Runnable::run).build();
    }
}

我已经使用 zipkin-server-2.23.2-exec jar 在端口 localhost:9411 作为默认端口启动服务器 在 cmd 上使用此命令。 java -jar zipkin-server-2.23.2-exec

我的 zipkin 已启动并且工作正常，我只是坚持将跟踪记录存储在我的 MysqL 数据库中，表正在正确创建。但是记录是空的。 我不知道为什么我认为我缺少任何配置。 我关注了 this 文章，因为他们显示在数据库中存储跟踪。 任何人都可以向我建议我要评估的地方。

解决方法

请使用 Spring Cloud Sleuth 3.1.0-SNAPSHOT（通过 2021.0.0-SNAPSHOT 火车，我们应该在 6 月 AFAIR 有 M1）。您可以在此处找到示例 https://github.com/spring-cloud-samples/spring-cloud-sleuth-samples/tree/3.1.x/data（请记住这部分 https://github.com/spring-cloud-samples/spring-cloud-sleuth-samples/blob/3.1.x/data/pom.xml#L33-L38）和文档 https://docs.spring.io/spring-cloud-sleuth/docs/3.1.0-SNAPSHOT/reference/html/integrations.html#sleuth-jdbc-integration。为了您的方便，我复制下面的代码

如果不想使用快照，则需要使用 Brave 的 p6spy 支持 https://github.com/openzipkin/brave/tree/master/instrumentation/p6spy 。请将 io.zipkin.brave:brave-instrumentation-p6spy 添加到类路径并更改项目自述文件中显示的属性
