PhysicalNamingStrategy bean仅通过配置文件实例化 [英] PhysicalNamingStrategy bean only instantiates via config file

问题描述

我在带有Hibernate的Spring应用程序中有一个自定义命名策略:

I have a custom naming strategy in a Spring app with Hibernate:

public class MyCustomPhysicalNamingStrategy implements PhysicalNamingStrategy {

  @Override
  public Identifier toPhysicalTableName(Identifier identifier, JdbcEnvironment jdbcEnvironment) {
    return Identifier.toIdentifier("my_custom_table_name");
  }

  // ...

}

The Spring documentation says I can tell Hibernate to use it either by setting spring.jpa.hibernate.naming.physical-strategy (which works fine), or like this:

或者，如果在应用程序上下文中有ImplicitNamingStrategy或PhysicalNamingStrategy bean，则Hibernate将被自动配置为使用它们.

Alternatively, if ImplicitNamingStrategy or PhysicalNamingStrategy beans are available in the application context, Hibernate will be automatically configured to use them

我需要使用第二种方法，因为我需要将一些信息从Spring的上下文传递到我的命名策略.但是，我无法正常工作.

I need to use this second method, as I need to pass some info from Spring's context to my naming strategy. However, I can't get it to work.

我正在以下配置类中创建Bean:

I'm creating the bean in the following configuration class:

@Configuration
public class PersistenceConfiguration {
  @Bean
  public PhysicalNamingStrategy physicalNamingStrategy() {
    return new MyCustomPhysicalNamingStrategy();
  }
}

我在这里想念什么?

谢谢.

我正在使用Spring Boot/Spring JPA 1.5.9.RELEASE，它提供了Hibernate core v.5.0.12.Final和Hibernate JPA API 2.1.

I'm on Spring Boot/Spring JPA 1.5.9.RELEASE, which gives me Hibernate core v.5.0.12.Final and Hibernate JPA API 2.1.

推荐答案

似乎只有Spring Boot 2支持.

It seems that this is only supported with spring boot 2.

请参阅:该文件在Spring Boot 1.5中不存在: https://github.com/spring-projects/spring-boot/tree/v1.5.14.RELEASE/spring-boot -autoconfigure/src/main/java/org/springframework/boot/autoconfigure/orm/jpa

This file is not present in spring boot 1.5: https://github.com/spring-projects/spring-boot/tree/v1.5.14.RELEASE/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/orm/jpa

(HibernateJpaAutoConfiguration.java没有它)
