升级到 Spring boot 2.5.1 和 spring cloud 2020.0.3 时，Netflix zuul 和 ribbon 的 Maven 依赖性有什么区别

Question

我正在尝试将我的 spring 引导版本从 2.1.5.RELEASE 升级到 2.5.1，因此我已将 spring 云版本从 Greenwich.RELEASE 更改为2020.0.3 根据发布序列 Spring spring 云的启动兼容性。我也在我的项目中使用 spring-cloud-starter-netflix-zuul 和 spring-cloud-starter-netflix-ribbon。我面临的问题是当我构建 Maven 时，出现如下错误

[ERROR] [ERROR] Some problems were encountered while processing the POMs:
[ERROR] 'dependencies.dependency.version' for org.springframework.cloud:spring-cloud-starter-netflix-zuul:jar is missing. @ com.xx.xxx.xxx:[unknown-version], C:\Users\xx\pom.xml, line xx, column xx
[ERROR] 'dependencies.dependency.version' for org.springframework.cloud:spring-cloud-starter-netflix-ribbon:jar is missing. @ com.xx.xxx.xxxh:[unknown-version], C:\Users\xx\pom.xml, line xx, column xx

我的pom文件如下

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.5.1</version>
    </parent>
    <repositories>
    </repositories>
    <dependencyManagement>

        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
        </dependency>
...

任何人都可以帮助解决此错误，在此先感谢

Answer 1

许多以前处于维护模式的 Netflix 相关模块已 removed in Spring Cloud 2020. This includes Ribbon and Zuul which you are using. The Spring Cloud team recommend 将 Ribbon 替换为 Spring Cloud Loadbalancer 并将 Zuul 替换为 Spring Cloud Gateway。

Answer 2

spring-cloud 和 netflix-zuul 将按以下版本运行。

spring-boot-starter-parent: 2.1.3.RELEASE
java.version: 1.8
spring-cloud.version: Greenwich.RELEASE
spring-cloud-starter-netflix-zuul: 2.1.0.RELEASE
spring-cloud-starter-netflix-eureka-client: 2.1.0.RELEASE
jackson-dataformat-xml: 2.9.9
spring-cloud-starter-netflix-eureka-server: 2.1.0.RELEASE

Answer 3

Spring removed zuul after 2.4.0 so it better to use below versions for smooth excution.

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.3.RELEASE</version>
        <relativePath /> <!-- lookup parent from repository -->
    </parent>

<properties>
    <java.version>1.8</java.version>
    <spring-cloud.version>Greenwich.RELEASE</spring-cloud.version>
</properties>


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