将spring cloud版本从Edgware升级到Hoxton

Question

我正在将spring boot版本从1.5.9升级到2.3.5，将spring cloud版本从Edgware.SR2升级到Hoxton.SR6。

当POM与Edgware一起运行时，它包含了spring-cloud-stream-schema、spring-cloud-starter-eureka和spring-cloud-sleuth-stream，如下所示。

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-stream-schema</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-eureka</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-sleuth-stream</artifactId>
    </dependency>

升级后，maven build给出以下错误。

[INFO] Scanning for projects...
[ERROR] [ERROR] Some problems were encountered while processing the POMs:
[ERROR] 'dependencies.dependency.version' for org.springframework.cloud:spring-cloud-stream-schema:jar is missing. @ line 89, column 15
[ERROR] 'dependencies.dependency.version' for org.springframework.cloud:spring-cloud-starter-eureka:jar is missing. @ line 97, column 15
[ERROR] 'dependencies.dependency.version' for org.springframework.cloud:spring-cloud-sleuth-stream:jar is missing. @ line 109, column 15

看起来这3个jars被移出或与Hoxton.SR6中的其他jars合并。

更新后的依赖项是什么？

Answer 1

现在，在Spring Boot版本2.x中不支持这些依赖项。

在pom.xml中添加这些更新的依赖项：

       <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>
        <dependency>
         <groupId>org.springframework.cloud</groupId>
         <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-sleuth</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-stream</artifactId>
        </dependency>

</dependency>

Answer 3

您可以考虑替换这些工件，如下所示：

1. spring-cloud-stream-schema：在this commit中，随着坐标的改变，它被更改为spring-cloud-schema-registry-core。考虑使用一个instead.
2. spring-cloud-starter-eureka：此starter已被弃用并已从物料清单in this commit中删除您可以考虑切换到spring-cloud-starter-netflix-eureka-client.
3. spring-cloud-sleuth-stream：它已被弃用，不应再使用。我建议你尽量去掉它，因为它与某些目的地不兼容，或者只是添加你想要使用的版本号，直到你可以删除它为止。您使用的Spring Cloud版本的物料清单中的版本是1.3.2.RELEASE.
