spring boot + netflix zuul app给java.lang.ClassNotFoundException：com.netflix.zuul.monitoring.CounterFactory

问题描述 投票：0回答：1

我正在使用spring boot + netflix zuul为我的微服务项目开发一个网关。网关连接到netflix eureka服务器并过滤请求。但是我无法启动zuul服务器

我在spring boot项目中包含了以下maven依赖项

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        <version>2.0.2.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-netflix-zuul</artifactId>
        <version>2.0.2.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>
    <dependency>
        <groupId>io.jsonwebtoken</groupId>
        <artifactId>jjwt</artifactId>
        <version>0.9.0</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
        <optional>true</optional>
    </dependency>
</dependencies>

启动spring boot应用程序时出现以下异常

使用依赖项

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
    <version>2.0.2.RELEASE</version>
</dependency>

代替

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-netflix-zuul</artifactId>
    <version>2.0.2.RELEASE</version>
</dependency>
