Ps:我不了解spring boot项目与PLAYFRAMEWORK的关系.

Ps: I do not understand how spring boot project is related to PLAYFRAMEWORK.

推荐答案

Spring Boot 1.3.5带有嵌入式Hibernate JPA提供程序(版本4.3，该功能已经可以与JPA 2.1一起使用).

Spring Boot 1.3.5 comes with embedded Hibernate JPA provider (version 4.3, that is already capable to work with JPA 2.1).

不幸的是，WAS 8.0仅支持JPA 2.0，因此您必须更改persistence.xml，

Unfortunately, WAS 8.0 supports JPA 2.0 only, so you have to change persistence.xml, so instead

<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
         http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"
         version="2.1">
 ...
 </persistence>

尝试一下:

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
    version="2.0">
...
</persistence>

此外，如果您打算使用Hibernate而不是嵌入式OpenJPA实现，则必须通过设置JVM属性 com.ibm.websphere.persistence.ApplicationsExcludedFromJpaProcessing = *

Also, if you intend to use Hibernate instead of embedded OpenJPA implementation, you have to turn OpenJPA off by setting JVM property com.ibm.websphere.persistence.ApplicationsExcludedFromJpaProcessing=*

不要忘记将类加载器策略设置为PARENT_LAST.

And don't forget to set classloader policy to PARENT_LAST.
