Hibernate 5.0.11 - AttributeConverter类注册了多次 [英] Hibernate 5.0.11 - AttributeConverter class registered mulitple times

问题描述

我将spring boot升级到1.4.2，并将hibernate升级到5.0.11.Final，并开始看到这个错误。不知道为什么HibernateJpaAutoConfiguration多次注册客户转换器，即使它只声明一次。

当我尝试运行bootRun时，会抛出以下异常。

任何帮助都是非常可观的。

解决方案

JPA的$ c> @EnableAutoconfiguration 是pa扫描两条路径，因为数据库配置位于子文件夹中，这是合理的。

  com.testOrg 
 
 com.testOrg.configuration 
  

org.springframework.orm。 520线上的jpa.persistenceunit.DefaultPersistenceUnitManager 会根据找到的扫描配置路径的数量多次添加转换器，
我认为其他类我们没有检查重复但转换器我们请检查它是否被注册多次，比抛出异常请参阅。 com.testOrg.configuration.MetadataBuilderImpl.java 第907行

为了解决这个问题，我将DatabaseConfiguration类从com.testOrg.configuration文件夹为main，因此只有一个类可以注册。

我希望这可以对某人有帮助。

I upgraded spring boot to 1.4.2 and hibernate to 5.0.11.Final and started seeing this error. Not sure why HibernateJpaAutoConfiguration is registering the customer converter multiple times even though it is declared only once.

Following exception is being thrown when I try to run to bootRun.

Any help would be really appreciable.

解决方案

Somehow the @EnableAutoconfiguration of JPA were passing two paths to get scanned, because the database configuration was in sub folder which makes sense.

com.testOrg

com.testOrg.configuration

org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager on line 520 is adding converters multiple times based on the number of scanned configuration paths found, I think for other classes we do not have check for duplicacy but for Converters we do have check if it gets registered multiple times than throw Exception see. com.testOrg.configuration.MetadataBuilderImpl.java line 907

To solve this, I moved my DatabaseConfiguration class out of "com.testOrg.configuration" folder to main and hence only one class to register.

I hope this might be helpful for someone.
