带有JPA的Spring Boot:将@Entity移到其他包中 [英] Spring Boot w/ JPA: move @Entity to different package

问题描述

我在使用Spring-Boot和JPA的第一步时遇到了麻烦.我从使用Gradle的一个非常简单的来自Git的示例开始.

I'm having trouble with my first steps using Spring-Boot with JPA. I've started with a pretty minimalistic example from Git using Gradle.

现在简单地将Customer移至另一个程序包，比如说hello2会导致异常Caused by: java.lang.IllegalArgumentException: Not an managed type: class hello2.Customer.我尝试添加

Now simply moving Customer to another package, let's say to hello2 results in an exception Caused by: java.lang.IllegalArgumentException: Not an managed type: class hello2.Customer. I tried to add

@ComponentScan(basePackageClasses= {Customer.class}) // AND OR @EnableJpaRepositories(basePackageClasses= {Customer.class})

@ComponentScan(basePackageClasses= {Customer.class}) // AND OR @EnableJpaRepositories(basePackageClasses= {Customer.class})

到Application，但没有成功.

我在做什么错了?

推荐答案

Spring Boot中实体的位置可以使用

Location of entities in Spring Boot can be configured using @EntityScan.

默认情况下，@EnableAutoConfiguration启用实体扫描所在的包(如果它不是默认包).

By default, @EnableAutoConfiguration enables entity scanning in the package where it's placed (if it's not a default package).
