NoSuchBeanDefinitionException: 没有名为“entityManagerFactory"的 bean 可用 [英] NoSuchBeanDefinitionException: No bean named 'entityManagerFactory' available
问题描述
我在构建时遇到此错误.我在这里提到了其他答案，但没有一个对我有用.
I am getting this error while building. I referred to other answers here, but none of them worked for me.
application.properties
application.properties
spring.datasource.platform=postgres
spring.datasource.url=jdbc:postgresql://localhost:5432/externalPoc
spring.datasource.username=postgres
spring.datasource.password=
spring.database.driverClassName=org.postgresql.Driver
spring.jpa.hibernate.ddl-auto=update
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.show-sql=false
hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
存储库:
@Repository
public interface CardRepository extends JpaRepository<CardRegistration, Serializable> {
Optional<Card> findByUuid(String uuid);
}
实体:
@Entity
public class Card extends AbstractBaseEntity implements Serializable {
String uuid;
String validFrom;
String validTo;
public String getValidFrom() {
return validFrom;
}
public void setValidFrom(String validFrom) {
this.validFrom = validFrom;
}
public String getValidTo() {
return validTo;
}
public void setValidTo(String validTo) {
this.validTo = validTo;
}
public String getUuid() {
return uuid;
}
public void setUuid(String uuid) {
this.uuid = uuid;
}
}

和主类(spring boot应用程序)
And main class (spring boot application)
@SpringBootApplication
@EnableJpaRepositories(basePackages = "com.start.new.project.externalPoc.model.repository")
@EntityScan(basePackages = "com.start.new.project.externalPoc.model")
public class ExternalPocApplication {
public static void main(String[] args) {
SpringApplication.run(ExternalPocApplication.class, args);
}
@Bean
public MapperFacade mapper() {
MapperFactory mapperFactory = new DefaultMapperFactory.Builder().build();
return mapperFactory.getMapperFacade();
}
}
我从 .m2 目录中删除了所有文件夹.再次运行 mvn clean install.得到了同样的错误.服务类自动装配存储库.控制器使用@RestController 注释.
I removed all the folder from .m2 directory. Ran mvn clean install again. Got the same error. The service class Autowires the repository. And controllers use @RestController annotation.
这就是确切的原因:
引起:org.springframework.beans.factory.BeanCreationException:创建名为(内部 bean)#4d3ca6c7"的 bean 时出错:无法解析设置构造函数时对 bean 'entityManagerFactory' 的引用论证；嵌套异常是org.springframework.beans.factory.NoSuchBeanDefinitionException:否名为entityManagerFactory"的 bean 可用
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#4d3ca6c7': Cannot resolve reference to bean 'entityManagerFactory' while setting constructor argument; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'entityManagerFactory' available
推荐答案
从 https://start 创建一个虚拟项目.spring.io(选择 Switch to the full version 并勾选 PostGres，例如)然后将您的类添加到该项目中.
Create a dummy project from https://start.spring.io (Choose Switch to the full version and tick PostGres, for example) and add your classes to that project afterwards.
这样你就不必担心依赖关系，默认情况下你会得到最新的.我昨天用过它，它对我来说就像一个魅力.
That way you don't have to bother about the dependencies and you would get the latest by default. I had used it yesterday and it worked like a charm for me.
