缺少工件 org.springframework.cloud:spring-cloud-starter-openfeign:jar:3.0.3-SNAPSHOT答案

【问题标题】：Missing artifact org.springframework.cloud:spring-cloud-starter-openfeign:jar:3.0.3-SNAPSHOT缺少工件 org.springframework.cloud:spring-cloud-starter-openfeign:jar:3.0.3-SNAPSHOT
【发布时间】：2021-08-13 18:23:47
【问题描述】：

我正在尝试向 pom.xml 添加“spring-cloud-starter-openfeign”依赖项

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

但我遇到了错误。

根据谷歌的一些发现，我添加了如下版本

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-openfeign</artifactId>
        <version>3.0.3</version>
</dependency>

但错误仍未解决。有人可以帮我解决这个问题吗？

下面是我的 pom.xml

我已经添加了 pom 文件。我正在尝试在我的微服务项目中的一项服务上创建一个假装客户端。由于 spring-cloud-starter-openfeign 依赖，我无法解决这个 pom。我最近在学习微服务，有人可以帮我解决这个pom文件

【解决方案1】：

您好，我终于通过添加下面的 spring-cloud-openfeign-core 解决了这个问题

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-openfeign-core</artifactId>
    <version>3.0.2</version>
</dependency>

分辨率：

我找到了这个解决方案，因为错误出现在 pom 文件的第 4 行，说 “缺少工件 org.springframework.cloud:spring-cloud-openfeign-core:jar:3.0.3-SNAPSHOT” 在为 spring-cloud-starter-openfeign 添加版本之后依赖。
表示添加 spring-cloud-starter-openfeign
后，Sping 正在搜索 openfeign-core 依赖项

所以下面更新pom.xml

【解决方案2】：

最后一个发布版本是 3.0.2 而不是 3.0.3 看这里https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-openfeign/3.0.2
