entityManagerFactory 未初始化

Question

我正在创建一个 portlet 以在 liferay 6.2 中加载。该 portlet 是一个 spring portlet，它有自己的数据库并使用 jpa。

我的 pom 是：

<?xml version="1.0"?>

我的 spring portlet 配置是：

我有一个抽象 class 使用泛型作为 DAO classes 的基础，我正在使用 @PersistenceContext

注入 EntityManager

public abstract class DaoImpl<T extends Serializable, K> implements Dao<T, K> {

    @PersistenceContext
    protected EntityManager em;

    private Class<T> type;
.......

当 liferay 服务器启动并尝试加载我的 portlet 时，我在初始化 EntityManagerFactory 时遇到错误

怎么了？也许我在配置中忘记了什么？

提前致谢

Answer 1

您在类路径 (2.0.Beta-20090815) 中使用带有测试版 JPA 2.0 库的 JPA2.1 提供程序 (Hibernate 5.0.6)。因此提供者尝试调用一个尚不存在的方法：Table.indexes().

使用 JPA 2.1 库。

entityManagerFactory 未初始化

entityManagerFactory not initialized

spring

hibernate-entitymanager

jpa-2.0
