org.apache.openjpa.lib.util.ParseException:等效属性键；openjpa.ConnectionUserName“；及；javax.persistence.jdbc.user“；指定

我对openjpa有问题，intellij idea 12我自动生成了文件“persistence.xml”和java对象，基于数据库的模型，创建一个PaginControl.java和PaginaDao.java，但要创建生成的EntityMaganerFactory

java，这就是应用程序崩溃的地方

package cl.im.ciclos.Dao;


import cl.im.ciclos.model.Pagina;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

public class PaginaDao {

    static EntityManagerFactory factory;
    static EntityManager em;

    public PaginaDao(){

        factory = Persistence.createEntityManagerFactory("sistemaPU");
        em = factory.createEntityManager(); //==>this line generates the exception.
    }

    public void savePagina(String nombre, String file){
        em.getTransaction().begin();
        Pagina pagina = new Pagina();
        pagina.setNombre(nombre);
        pagina.setNombreArchivo(file);
        em.persist(pagina);
        em.getTransaction().commit();
    }
}

那么，将META-INF文件夹更改为您指定的位置（

/resources/META-INF

），但只更改例外情况：

OpenJPA似乎没有拾取您的

persistence.xml

，因为META-INF文件夹应该位于不同的位置。它应该是这样的（

src/main/resources/META-INF

下的

persistence.xml

）：

---

@Isma90这是一个与以前不同的异常，它表明找到了persistence.xml。请显示整个堆栈跟踪。好吧，将META-INF文件夹更改为您指定的位置（

/resources/META-INF

），但只更改异常<代码>javax.el.ELException:/main.xhtml:javax.persistence.PersistenceException:sistemaPU出现显式持久性提供程序错误尝试以下发现的实现后：org.apache.openjpa.persistence.PersistenceProviderImpl from provider:org.apache.openjpa.persistence.PersistenceProviderImpl@Isma90似乎缺少依赖项，但是如果不查看堆栈跟踪的相关部分，就很难判断这一点。

异常包含：

请不要将openjpa.RuntimeUnenhancedClasses设置为受支持。查看openjpa文档以找到更好的增强策略。
