tomee - 如何使用RESOURCE_LOCAL数据源

我有一些可以使用JTA的类（ejb，webservices，mdb等）。对于某些课程，我需要RESOURCE_LOCAL（不能注入）。但是我不能得到tomee引用RESOURCE_LOCAL的jndi名称。你如何设置tomee和RESOURCE_LOCAL？我似乎无法在网上找到一个好例子，我不想在我的persistence.xml文件中输入任何用户名和密码。tomee - 如何使用RESOURCE_LOCAL数据源

tomee.xml有这样的：

<Resource id="MYDS" type="DataSource"> 
     JdbcDriver com.mysql.jdbc.Driver 
     JdbcUrl jdbc:mysql://127.0.0.1:3306/maestro 
     UserName myusername 
     Password mypassword 
     JtaManaged false 
</Resource>

persistence.xml样子：

<?xml version="1.0" encoding="UTF-8"?> 
<persistence version="2.0" 
    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_2_0.xsd"> 
    <persistence-unit name = "MYDS" transaction-type = "RESOURCE_LOCAL">  
     <provider>org.hibernate.ejb.HibernatePersistence</provider>   
      <non-jta-data-source>MYDS</non-jta-data-source> 
    </persistence-unit>   
</persistence>

我在EntityManagerFactory查找使用名称MYDS，但得到这个错误：

什么版本的TomEE是这样的？ –

7.0.1和7.0.1（最新2个版本） – user18896654353

的解决方案似乎这是（仍在验证）：（不是很intuative或文件，增加OpenEJB的：资源来JPA和JPA不起作用，删除它从RESOURCE_LOCAL和RESOURCE_LOCAL不工作）

<?xml version="1.0" encoding="UTF-8"?> 
<persistence version="2.0" 
    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_2_0.xsd"> 
    <persistence-unit name = "MYDS" transaction-type = "RESOURCE_LOCAL">  
     <provider>org.hibernate.ejb.HibernatePersistence</provider>   
      <non-jta-data-source>openejb:Resource/MYDS</non-jta-data-source> 
    </persistence-unit>   
    <persistence-unit name="MYDSJPA" transaction-type = "JTA"> 
     <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider> 
     <jta-data-source>MYDS</jta-data-source>    
     </properties> 
    </persistence-unit> 
</persistence>

谢谢！这节省了我的一天。 – npocmaka

你如何让你的持久单元？手动？

如果使用注射：

@PersistenceUnit EntityManagerFactory emf; 
@PersistenceContect EntityManager em;

TomEE解决了数据源为你从它的短名称（在tomee.xml ID），否则你需要给它充分的JNDI名称，我认为是用java：OpenEJB的/资源/ MYDS

是的，我正在注入EnityManager，这个问题似乎是JTA与RESOURCE_LOCAL（从我上面的答案）不同的jndi命名方案。我认为这是新的或错误，因为老版本的tomee我记得使用相同的jndi类型字符串 – user18896654353

JTA应该由tomee提供，非JTA可能由hibernate根据版本和配置查找，即使tomee仍然提供给提供者（hibernate忽略它，因为它调用JndiServiceImpl）。 –
