Spring boot eclipse maven WAS：创建名为“entityManagerFactory”的bean时出错，答案

【问题标题】：Spring boot eclipse maven WAS : Error creating bean with name 'entityManagerFactory',Spring boot eclipse maven WAS：创建名为“entityManagerFactory”的bean时出错，
【发布时间】：2016-10-26 08:22:14
【问题描述】：

我正在尝试将我的 Web 应用程序部署到 WAS8，但我收到此错误消息。请帮忙！！

我的应用程序在运行命令时工作正常：“mvn spring-boot:run”。我已经查看了许多与如何将 Spring Boot 项目部署到 WAS8 相关的网站，但我仍然无法完成这项工作。我不知道这里缺少什么。我是 websphere 的新手，我对 websphere 的配置了解不多。请帮忙！！

# Hibernate ddl auto (create, create-drop, update, validate)
spring.jpa.hibernate.ddl-auto = update

# Naming strategy
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.EJB3NamingStrategy

# Use spring.jpa.properties.* for Hibernate native properties (the prefix is

# The SQL dialect makes Hibernate generate better SQL for the chosen database
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.SQLServerDialect


com.ibm.websphere.persistence.ApplicationsExcludedFromJpaProcessing=*

Ps：不明白spring boot项目和PLAYFRAMEWORK有什么关系。

【问题讨论】：

见this question。
我不明白答案，加上我不使用PlayFramework。有没有一步一步来做到这一点？我一直在网上关注许多“解决方案”，我什至不明白（因为我不明白。如果我明白，我就不会在这里问了）。
您的 Spring Boot 版本包含 Hibernate v4.3.11，它实现了 JPA 2.1。 WAS 8 仅支持 JPA 2.0。

标签： java jpa web spring-boot websphere

【解决方案1】：

Spring Boot 1.3.5 带有嵌入式 Hibernate JPA 提供程序（4.3 版，已经能够与 JPA 2.1 一起使用）。

很遗憾，WAS 8.0 只支持 JPA 2.0，所以你必须更改 persistence.xml，所以改为

<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>

试试这个：

<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>

另外，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=* 来关闭 OpenJPA

别忘了将类加载器策略设置为 PARENT_LAST。

答案部分覆盖here。

【讨论】：

抱歉，我不明白 PARENT_LAST 是什么。我已经更改了 persistence.xml 并在我的 application.properties 中添加了“com.ibm.websphere.persistence.ApplicationsExcludedFromJpaProcessing=*”。但是，同样的错误仍在发生。为什么？？
谢谢，Magic Wand，这并不能解决我的问题，但感谢您努力展示如何正确处理。
