No Feign Client for loadBalancing defined. Did you forget to include spring-cloud-starter-netflix-ri

问题原因网上有好几种解决方案，我分别列在下边希望能帮到你
这个最好启动类和远程fegin都能在统一的包名下边，确保能扫描到fegin接口

错误如下：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'bizLeaveController': Unsatisfied dependency expressed through field 'bizLeaveService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'bizLeaveServiceImpl': Unsatisfied dependency expressed through field 'sysClient'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.zhby.inter.client.SysClient': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalStateException: No Feign Client for loadBalancing defined.

解决办法1

添加spring-cloud-starter-loadbalancer,排除 Nacos 的 Ribbon
原因是因为这个冲突了好像

<dependency>
	<groupId>com.alibaba.cloud</groupId>
	<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
	<exclusions>
		<exclusion>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
		</exclusion>
	</exclusions>
</dependency>
<dependency>
	<groupId>org.springframework.cloud</groupId>
	<artifactId>spring-cloud-starter-loadbalancer</artifactId>
	<version>2.2.1.RELEASE</version>
</dependency>

解决方案2

出现以下情况：少了服务引用了 加上以下即可
No Feign Client for loadBalancing defined.
Did you forget to include spring-cloud-starter-netflix-ribbon?

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>
