## 报错信息简化 ##

java.lang.IllegalStateException: Failed to load ApplicationContext 。

这种报错信息，往下找 Caused by，从这里开始看

> Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'feignTest': Unsatisfied dependency expressed through field 'itemClient'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.hmall.common.client.ItemClient' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: \{@org.springframework.beans.factory.annotation.Autowired(required=true)\}

## 错误原因 ##

因为之前的报错，在网上找解决方案，最终在@SpringBootTest后加上了类名，如下：

@SpringBootTest(classes = FeignTest.class)，导致仅扫描本类。

将注解(classes = FeignTest.class)去掉，仅保留@SpringBootTest
