升级到Spring Boot 2.5.1和Spring Cloud 2020.0.3时，Netflixzuul和ribbon的maven依赖性是否有任何差异？

Question

我正在尝试将我的Spring启动版本从2.1.5升级。RELEASE到2.5.1，所以我已经从格林威治更改了Spring云版本。根据Spring云的发布列车Spring Boot兼容性，RELEASE到2020.0.3。我还在我的项目中使用sping-Cloud-starter-netfex-zuul和sping-Cloud-starter-netfex-ribbon。我面临的问题是，当我构建maven时，我得到了如下错误

[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>

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

有人可以帮助解决这个错误，提前谢谢

Answer 1

Spring在2.4.0版本后删除了zuul，因此最好使用以下版本，以便顺利执行。

<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>

Answer 2

spring cloud和netflix zuul将按照以下版本运行。

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

许多之前处于维护模式的Netflix相关模块已在Spring Cloud 2020中移除。这包括你正在使用的Ribbon和Zuul。Spring Cloud团队建议用Spring Cloud Loadbalancer替换Ribbon，用Spring Cloud Gateway替换Zuul。
