运行时报错At least one JPA metamodel must be present!有没有大神解答下

Question

<dependency>   <groupId>org.springframework.boot</groupId>   <artifactId>spring-boot-starter-data-jpa</artifactId></dependency><dependency>   <groupId>mysql</groupId>   <artifactId>mysql-connector-java</artifactId></dependency>基本都和老师的一样,一开始以为用eclipse不行,换了idea还是不行

Answer 1

楼主有没有解决啊   同问

Answer 2

还是不行,这样写直接报错了,其实好像压根就没启动到数据库

spring:

  profiles:

    active: prod

  datasource:

    driver-class-name: com.mysql.jdbc.Driver

    url: jdbc:mysql://127.0.0.1:3306/girl

    username: root

    password: mysql

  jpa:

    hibernate:

      ddl-auto: create

    show-sql: true  

我去掉jpa,删除数据库,也没报错

Answer 3

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
	<groupId>mysql</groupId>
	<artifactId>mysql-connector-java</artifactId>

树形结构的xml，你的大树没有根。
