相关疑难解决方法(0)

我正在构建一个基于Gradle的Java SE应用程序,它基于Hibernate构建,是我的首选ORM.我的计划是weld-se使用CDI注释EntityManagers在整个应用程序中进行注射.

基于HibernateUtilHibernate文档中的常见帮助程序类,我转向JPA接口并添加了@Produces注释以提供生产者方法(我还添加了一个空META-INF/beans.xml):

package dao;

import javax.enterprise.inject.Disposes;
import javax.enterprise.inject.Produces;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

public class HibernateUtil {
    private static final EntityManagerFactory emf = buildEntityManagerFactory();

    private static EntityManagerFactory buildEntityManagerFactory() {
        try {
            return Persistence.createEntityManagerFactory("persistenceUnit");
        } catch (Throwable ex) {
            System.err.println("Initial EntityManagerFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    @Produces
    public static EntityManager createEntityManager() {
        return emf.createEntityManager();
    }

    public static void closeEntityManager(@Disposes EntityManager em) {
        System.out.println("Closing EM");
        try …
