zipkin错误创建类路径资源中定义的名称为“webMvcMetricsFilter”的bean时出错

Question

当我尝试集成 zipkin 时。它引发了这个错误

Error Msg:Error starting Tomcat context. Exception: org.springframework.beans.factory.UnsatisfiedDependencyException. Message: Error creating bean with name 'webMvcMetricsFilter' defined in class path resource [org/springframework/boot/actuate/autoconfigure/metrics/web/servlet/WebMvcMetricsAutoConfiguration.class]: Unsatisfied dependency expressed through method 'webMvcMetricsFilter' parameter 0;

版本：

• Springboot 2.2.4
• SpringCloud Hoxton.SR1（侦探：2.2.1）
• 拉链2.19.9

@EnableZipkinServer
@SpringBootApplication
public class C4ZipkinApplication {

    public static void main(String[] args) {
        SpringApplication.run(C4ZipkinApplication.class, args);
    }

}

Answer 1

您的应用程序在 Tomcat 服务器中启动，但 Zipkin 使用另一台服务器，但我不知道该名称，我将此代码包含到 spring boot starter web dependency 中以忽略 tomcat 服务器

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-tomcat</artifactId>
                </exclusion>
            </exclusions>
</dependency>

这对我有用，试试吧

如果您使用配置服务器，请记住在运行微服务之前运行它。
