开始构建(第一个)
spring boot应用程序,这是我的spring boot主类(

@EnableAutoConfiguration
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class,args);

我一直得到以下错误.我想要添加什么？为什么我需要添加一个名为’entityManagerFactory’的bean bean？甚至在使用弹簧靴之后是否有必要？ 如果那件事,我的回购看起来像这样 public interface RegistrationRepo extends JpaRepository<User,Long> {
User findByEmail(String email);
}
application.properties spring.datasource.url=jdbc:mysql://localhost:3306/Test spring.datasource.username=root spring.datasource.password=root spring.datasource.driver-class-name=com.mysql.jdbc.Driver spring.jpa.hibernate.ddl-auto=update server.port=8181 尝试为repo添加@Repository注释,并在主类中添加了@enableJpaRepositories注释.什么都没有帮助. 解决方法
问题不在于直接启动版本,问题在于staled hibernate jar.由于我在项目中添加了JPA支持,因此使用(??)Hibernate作为JPA实现在内部启动并尝试使用(??)这些jar.由于我的本地仓库已经损坏了hibernate-entity- * jar,这种奇怪的错误正在发生.
他们的comment in the code确认他们在内部使用了hibernate. <!-- JPA Data (We are going to use Repositories,Entities,Hibernate,etc...) -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
从我的maven本地回购中删除了完整的hibernate文件夹,现在看来还可以. （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
