带有Spring Boot 2.2和Hoxton云的Zipkin

Question

我想将我的项目Zipkin设置更新到Spring Boot 2.2.2。释放和Spring云霍克斯顿。但看起来简单的jars更新是不够的。

我认为旧的设置（它适用于Spring Boot 2.1.5. RELEASE和Greenwich. SR2）也适用于Boot 2.2.2. RELEASE和Hoxton. RELEASE，但似乎我仍然错过了一些东西。

    <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>

        <dependency>

        <dependency>

            <artifactId>zipkin-server</artifactId>
            <version>${zipkin.version}</version>
        </dependency>
        <dependency>
            <groupId>io.zipkin.java</groupId>
            <artifactId>zipkin-autoconfigure-ui</artifactId>

            <scope>runtime</scope>
        </dependency>
        ...
    </dependencies>

我得到以下异常（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

这是一个版本问题。Zipkin正式建议在spring-boot 2. x之后使用zipkin-serverinstate客户服务器。

对我来说，库在spring boot 2.1.8下运行良好。使用spring cloud Greenwich释放。SR6
