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，spring cloud版本从Edgware.SR2升级到Hoxton.SR6。

POM 包括spring-cloud-stream-schema、spring-cloud-starter-eureka 和spring-cloud-sleuth-stream，如下所示，当它与Edgware 一起运行时。

    <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 报如下错误。

[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 jar 被移出或与 Hoxton.SR6 中的其他 jar 合并。

更新后的依赖项是什么？

Answer 1

Spring Boot 2.x 版现在不支持这些依赖项。

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>

注意：将云版本改为Horton.SR9

Answer 2

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-schema-registry-client</artifactId>
    <version>1.0.9.RELEASE</version>
</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>

Answer 3

您可以考虑按如下方式替换这些人工制品：

1. spring-cloud-stream-schema：在this commit 中，它已更改为spring-cloud-schema-registry-core，因为它的坐标已更改。考虑改用那个。
2. spring-cloud-starter-eureka：此启动器已弃用并已从 BOM 中删除 in this commit 您可以考虑切换到 spring-cloud-starter-netflix-eureka-client。
3. spring-cloud-sleuth-stream：已弃用，不应再使用。我建议您尝试摆脱它，因为它与某些目的地不兼容，或者只是添加您要使用的版本号，风险自负，直到您可以将其删除。您使用的 Spring Cloud 版本的 BOM 中的版本是 1.3.2.RELEASE。
