EntityCURD操作的参数和返回值

以下是netbeans根据实体自动生成的CURD模板：

/*

 */

package com.medea.order.session;

import com.medea.order.entity.Storeorder;

import java.util.List;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

/**
 *
 * @author Administrator
 */
@Stateless
public class StoreorderFacade implements StoreorderFacadeRemote {
    @PersistenceContext
    private EntityManager em;

    public void create(Storeorder storeorder) {
        em.persist(storeorder);
    }

    public void edit(Storeorder storeorder) {
        em.merge(storeorder);
    }

    public void remove(Storeorder storeorder) {
        em.remove(em.merge(storeorder));
    }

    public Storeorder find(Object id) {
        return em.find(Storeorder.class, id);
    }

    public List<Storeorder> findAll() {
        List<Storeorder> so=em.createQuery("select object(o) from Storeorder as o").getResultList();
      //  XmlUtil.writeXML(so, "aa");
        return so;
    }

   

}

可以参考一下参数和返回值，然后自己根据情况修改。
