我按照 Intellij 界面创建了这个项目。我所做的唯一更改是降级 Spring Boot 版本，从 3.0.1 降级到 2.7.5

Answer 1

为了解决这个问题，我不得不降级 pom.xml 上的 Spring Cloud 版本

<properties>
        <java.version>17</java.version>
        <spring-cloud.version>2021.0.5</spring-cloud.version>
</properties>

Answer 2

就我而言，spring-boot 版本和 feign 版本不匹配。通过以下更改解决了我的问题：

<propertiessss>
    <maven.compiler.source>17</maven.compiler.source>
    <maven.compiler.target>17</maven.compiler.target>
    <java.version>17</java.version>
    <springBoot.version>2.7.9</springBoot.version>
    <version.spring.framework>5.3.22</version.spring.framework>
    <spring.cloud.openfeign.version>3.1.6</spring.cloud.openfeign.version>
</propertiessss>

Answer 3

对我来说，我不知道你必须添加

@EnableFeignClients

在@SpringBootApplication类下
