Zipkin 與 Spring Boot 2.2 和 Hoxton Cloud

Question

我想將我的項目 Zipkin 設置更新為 Spring Boot 2.2.2.RELEASE 和 Spring Cloud Hoxton.RELEASE，但看起來簡單的 jars 更新是不夠的。

我認為舊的設置（它對 Spring Boot 2.1.5.RELEASE 和 Greenwich.SR2 工作正常）也適用於 Boot 2.2.2.RELEASE 和 Hoxton.RELEASE，但似乎我仍然錯過了一些東西。

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.2.RELEASE</version>
        <relativePath/>
    </parent>

    <properties>
        ...
        <spring-cloud.version>Hoxton.RELEASE</spring-cloud.version>
<!--        <zipkin.version>2.12.9</zipkin.version> does not work either-->
        <zipkin.version>2.11.8</zipkin.version>
        ...  
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zipkin</artifactId>
        </dependency>
        <dependency>
            <groupId>io.zipkin.java</groupId>
            <artifactId>zipkin-server</artifactId>
            <version>${zipkin.version}</version>
        </dependency>
        <dependency>
            <groupId>io.zipkin.java</groupId>
            <artifactId>zipkin-autoconfigure-ui</artifactId>
            <version>${zipkin.version}</version>
            <scope>runtime</scope>
        </dependency>
        ...
    </dependencies>

我收到以下異常（ java.lang.NoClassDefFoundError: zipkin2 /internal/Buffer$Writer ）：

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'webMvcMetricsFilter' defined in class path resource [org/springframework/boot/actuate/autoconfigure/metrics/web/servlet/We

Answer 1

是版本問題。 Zipkin 官方推薦在spring-boot 2.x之后使用zipkin-server客戶服務器。

對我來說， 2.12.9庫在spring-boot 2.1.8.RELEASE和spring-cloud Greenwich.SR6下運行良好
