我正在创建一个要在liferay 6.2中加载的portlet。 portlet是一个Spring portlet,它有自己的db并使用jpa。

我的pom是:

我对portlet的spring配置是:

<?xml version="1.0"?>

        <property name="username" value="xxxx" />
        <property name="password" value="xxx" />
    </bean>

</beans>

我有一个抽象类,使用泛型作为DAO类的基础,我使用@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

出了什么问题?也许我在配置中忘了一些东西?

答案 0 :(得分:2)

您正在使用JPA2.1提供程序(Hibernate 5.0.6)和类路径中的Beta版JPA 2.0库(2.0.Beta-20090815)。因此,提供商尝试调用尚不存在的方法:Table.indexes()

使用JPA 2.1库。
