错误描述

Description:

Field FeignClient in xx required a bean of type 'org.springframework.cloud.openfeign.FeignContext' that could not be found.

The injection point has the following annotations:
	- @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Consider defining a bean of type 'org.springframework.cloud.openfeign.FeignContext' in your configuration.

原因

版本冲突。之前SpringBoot版本用的2.5.3没这个问题，升级到3.0.1之后报错[1]

因为Spring Boot 3.0.0 中的Spring.factories被移除，所以之前的版本配置失败了。

解决

在启动类之前加上
@ImportAutoConfiguration({FeignAutoConfiguration.class})

尝试再次启动报错

可能因为Feign的自动配置需要db依赖，我直接在pom中加上

        <dependency>
            <groupId>com.mysql</groupId>
            <artifactId>mysql-connector-j</artifactId>
        </dependency>

之后顺利启动
