我有一个 DaoService，它在应用程序启动时被初始化。

public DaoService() {
    Map<String, String> properties = new HashMap<String, String>();
    properties.put("javax.persistence.jdbc.user", "admin");
    properties.put("javax.persistence.jdbc.password", "admin");
    factory = Persistence.createEntityManagerFactory("$objectdb/db/points.odb", properties);
    //exception!
}

但是每次它都会触发这个异常:

    javax.persistence.PersistenceException: Explicit persistence provider error(s) occurred for "$objectdb/db/points.odb" after trying the following discovered implementations: org.apache.openjpa.persistence.PersistenceProviderImpl, com.objectdb.jpa.Provider from provider: com.objectdb.jpa.Provider

我尝试过使用和不使用这个 persistence.xml

<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
 http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0">

   <persistence-unit name="my-pu">
     <description>My Persistence Unit</description>
     <provider>com.objectdb.jpa.Provider</provider>


     <class>net.heatboxes.dao.entity.UserEntity</class>
     <properties>
       <property name="javax.persistence.jdbc.url"
                 value="my.odb"/>
       <property name="javax.persistence.jdbc.user" value="admin"/>
       <property name="javax.persistence.jdbc.password" value="admin"/>
     </properties>
   </persistence-unit>

</persistence>

最佳答案

我终于明白了。我根本不应该使用任何 persistence.xml。当我不使用它时，我得到了这个错误:

HTTP Status 500 - org.apache.openjpa.persistence.ArgumentException: A JDBC Driver or DataSource class name must be specified in the ConnectionDriverName property. Available properties in configuration are "org.apache.openjpa.jdbc.conf.JDBCConfigurationImpl@fdaf18ee".

openjpa 与我的 objectdb.jar 的现有 JPA 冲突。

为了避免它，我从我的 TomEE/lib 文件夹中删除了 openjpa-asm-shaded-X.X.X.jar。

总结

仅:

Persistence.createEntityManagerFactory("$objectdb/db/painInTheAss.odb");

对于 EntityManagerFactory

仅:

objectdb-ee.jar

用于依赖项中的 objectdb 库。

只有没有:

openjpa-asm-shaded-X.X.X.jar

在 TomEE/lib

Netbeans 仍然可以为您创建 persistance.xml，这会破坏一切。如果您仍然不成功并使用 NetBeans，请清除其缓存，在 C:\Users\YOURNAME\AppData\Local\NetBeans\Cache

您可能会查看 YOURPROJECT\nbproject\project.properties 以查看您玩过的一些旧的格式错误的设置并保持原样。
