用springboot jpa 报：No property yer found for type OrderMaster错

报错代码

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerAdapter' defined in class path resource [org/springframework/boot/autoconfigure/web/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Bean instantiation via factory method failed;  nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.mvc.method.annotation. RequestMappingHandlerAdapter]: Factory method 'requestMappingHandlerAdapter' threw exception;  nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mvcConversionService' defined in class path resource [org/springframework/boot/autoconfigure/web/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Bean instantiation via factory method failed;  nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.format.support. FormattingConversionService]: Factory method 'mvcConversionService' threw exception;  nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'orderMasterDao': Invocation of init method failed;  nested exception is org.springframework.data.mapping.PropertyReferenceException: No property yer found for type OrderMaster!

 最后一行

嵌套异常是org.springframework.data.mapping.PropertyReferenceException:没有找到类型OrderMaster的属性! 

错误代码

public interface OrderMasterDao extends JpaRepository {

//    根据openID查询这个人的订单 分页
    Page findBybBuyerOpenid(String buyerOpenId, Pageable pageable);
}

 原因：方法名粗心大意写错

修改完代码

public interface OrderMasterDao extends JpaRepository {

//    根据openID查询这个人的订单 分页
    Page findByBuyerOpenid(String buyerOpenId, Pageable pageable);
}
