贴上我的spring配置文件
spring.datasource.url=jdbc:mysql://localhost:3306/boot?useUnicode=true&characterEncoding=utf-8spring.datasource.username=rootspring.datasource.password=rootspring.datasoruce.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.properties.hibernate.hbm2ddl.autu=updatespring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialectspring.jpa.show-sql=true

Answer 1

Causedby:org.springframework.data.mapping.PropertyReferenceException:NopropertynamefoundfortypeUser!实体User没有定义name属性。

Answer 2

问题的实际是我在定义接口的时候直接定义了findUserNameByName，但是我user里并没有定义name这个属性，定义的是userName，把接口的名字改为findUserNameByuserName就好了
