找不到SpringBoot EntityManagerFactory

问题描述

因此，尝试使用JPA实现运行第一个sprinboot应用程序，并收到以下错误:

So, trying to run first sprinboot application with JPA implementation and got the following error :

Description:

Field personneDAO in com.example.demo.controller.PersonneController required a bean named 'entityManagerFactory' that could not be found.


Action:

Consider defining a bean named 'entityManagerFactory' in your configuration.

试图在我的仓库中添加@Repositoy，并在主仓库中添加@EnableJpaRepositories，但这无济于事...

tried to add @Repositoy on my repo, and @EnableJpaRepositories to the main, but it doesn't helps...

存储库(没什么花哨的):

the repository (nothing too fancy):

@Repository
public interface PersonneDAO extends JpaRepository<Personne, Integer>{
}

主要:

@SpringBootApplication
@EnableJpaRepositories(basePackages ="com.example.demo.repository")

public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

渐变依赖项:

dependencies {
    compile('org.springframework.boot:spring-boot-starter-web')
    providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    compile('org.apache.tomcat.embed:tomcat-embed-jasper')
    compile group: 'org.hibernate', name: 'hibernate-core', version: '5.2.16.Final'
    compile group: 'org.springframework.data', name: 'spring-data-jpa', version: '2.0.6.RELEASE'
    testCompile group: 'com.microsoft.sqlserver', name: 'mssql-jdbc', version: '6.5.1.jre9-preview'
}

有创意的人吗? :/

PS:忘记了application.properties

PS : forgot the application.properties

spring.mvc.view.prefix = /WEB-INF/
spring.mvc.view.suffix = .jsp

spring.jpa.hibernate.ddl-auto=create
spring.datasource.url=jdbc:sqlserver://localhost/DB_TEST
spring.datasource.username=sa
spring.datasource.password=Pa$$w0rd
spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver

推荐答案

在没有spring-boot-starter-data-jpa作为依赖项的情况下，JPA不会自动配置.有了依存关系，您甚至不需要@EnableJpaRepositories.

JPA will not get auto-configured without spring-boot-starter-data-jpa as a dependency. With the dependency in place, you shouldn't even need @EnableJpaRepositories.

此外，您可以删除spring-data-jpa，因为spring-boot-starter-data-jpa已经依赖于此.

Also, you may remove spring-data-jpa as spring-boot-starter-data-jpa already depends on that.
