Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyRefer

用springboot jpa做项目测试时报错

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 'orderMasterRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property buyerOpenid found for type OrderMaster!

最主要的原因：

Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property buyerOpenid found for type OrderMaster! Did you mean 'buyer_Openid'?

问题原因：

由于springboot 中jpa默认自动将实体类中的驼峰命名转化为下划线隔开的方式进行数据库查询，将字段buyerOpenid自动转换为buyer_Openid 导致数据库找不到该字段

解决办法：
在配置文件中取消自动将驼峰命名转为下划线形式

spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
