构建时出现此错误。我在这里提到了其他答案，但是没有一个对我有用。
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
仓库：
@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）
@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安装。得到了同样的错误。
服务类自动装配资源库。
控制器使用@RestController批注。
这是确切的原因：
引起原因：org.springframework.beans.factory.BeanCreationException：
创建名称为“（（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
论点嵌套异常为
org.springframework.beans.factory.NoSuchBeanDefinitionException：否
名为“ entityManagerFactory”的bean可用
最佳答案
从https://start.spring.io创建一个虚拟项目（选择Switch to the full version and tick PostGres, for example），然后将类添加到该项目中。
这样，您就不必担心依赖项，并且默认情况下您将获得最新信息。我昨天用过它，它对我来说就像一种魅力。
关于java - NoSuchBeanDefinitionException:没有可用的名为“entityManagerFactory”的bean，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/50578216/
