SSM做单元测试的时候报错 No qualifying bean of type 'com.**.entity.**' available: expected at least 1 bean

做SSM单元测试时候出现报错

java.lang.IllegalStateException: Failed to load ApplicationContext

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

首先，检查一下配置文件：
配置文件在根目录下

检查test类上面的配置：
配置路径没有问题

检查注释扫描的配置：
注释扫描配置没有问题

检查mapper.xml配置文件：
namespace位置配置没有问题

检查注入注释添加：
entity当中的类没有加入@Component注释，导致注入失败，造成报错。




错误修改：
加上@Component注释，问题解决

注：个人遇到的一些问题已经自己找到的不成熟的解决方案，欢迎大家借鉴以及交流讨论。
