问题：

A component required a bean of type 'com.atao.project.feign.FeignJobInfoService' that could not be found.

解决办法：

启动类中增加注解@EnableFeignClients

//@EnableFeignClients(clients = { FeignJobInfoService.class }) //方法1
@EnableFeignClients(basePackages = "com.atao.project.feign")//方法2

这时又出现了新的问题：

Unexpected exception during bean creation; nested exception is java.lang.IllegalStateException: No Feign Client for loadBalancing defined. Did you forget to include spring-cloud-starter-loadbalancer?

原因：

SpringCloud Feign在Hoxton.M2 RELEASED版本之后不再使用ribbon
而是使用spring-cloud-loadbalancer，所以在不引入spring-cloud-loadbalancer情况下会报错

解决办法：修改pom文件,增加loadbalancer

        <!-- 负载均衡-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-loadbalancer</artifactId>
            <version>3.0.3</version>
        </dependency>

ps:我这里nacos、feign版本：

				<!--openfeign-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-openfeign</artifactId>
            <version>3.0.1</version>
        </dependency>
                <!--        引入nacos依赖-->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
            <version>2021.1</version>
        </dependency>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
            <version>2021.1</version>
        </dependency>

OK,解决
