jpa - 无法获取数据源。无法在 JBoss 5.1 中使用 JPA EntityManager (EclipseLink)

标签 jpa jboss eclipselink jboss5.x

我在将 JPA (EclipseLink) 放在 JBoss Server 中时遇到了很多困难。我通常使用Tomcat，它很简单......

  • 我将 mysql-ds.xml 从/jboss-5.1.0.GA/docs/examples/jca 复制到/jboss-5.1.0.GA/servers/default/deploy/然后我配置了它。

    • mysql-ds.xml 文件:
    <?xml version="1.0" encoding="UTF-8"?>
<datasources>
  <local-tx-datasource>
    <jndi-name>EDeliveryUnit</jndi-name>
    <connection-url>jdbc:mysql://localhost:3306/edelivery_db</connection-url>
    <driver-class>com.mysql.jdbc.Driver</driver-class>
    <user-name>root</user-name>
    <password>root</password>
    <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
    <check-valid-connection-sql>SELECT * FROM systemuser</check-valid-connection-sql>
    <metadata>
       <type-mapping>mySQL</type-mapping>
    </metadata>
  </local-tx-datasource>
</datasources>
  • 然后我在我的 WebApplication 中配置了 persistence.xml。

    • 持久性.xml:
    <?xml version="1.0" encoding="UTF-8" ?>
<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"
version="2.0" xmlns="http://java.sun.com/xml/ns/persistence">
<persistence-unit name="edeliveryPU"
    transaction-type="RESOURCE_LOCAL">
    <jta-data-source>jdbc/EDeliveryUnit</jta-data-source>
    <non-jta-data-source>jdbc/EDeliveryUnit</non-jta-data-source>
    <class>pt.inov.spocs.board.server.model.entity.SystemUser</class>
    <class>pt.inov.spocs.board.server.model.entity.UserSession</class>
    <properties>
        <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
        <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/edelivery_db" />
        <property name="javax.persistence.jdbc.user" value="root" />
        <property name="javax.persistence.jdbc.password" value="root" />
        <property name="eclipselink.jdbc.batch-writing" value="JDBC" />
        <property name="eclipselink.ddl-generation" value="drop-and-create-tables" />
    </properties>
</persistence-unit>

    最后我实例化了 EntityManager:
    private EntityManagerFactory emf;
private EntityManager em;

public Controller() {
    System.out.println("Begin..");

    emf = Persistence.createEntityManagerFactory("edeliveryPU");
    em = emf.createEntityManager();

    user = em.find(SystemUser.class, new Long(1));
    System.out.println("Username: " + user.getUsername() + " | pass: "
            + user.getPassword());
}

    当我部署它时，我的 jboss 出现了这些错误:

    我尝试了很多不同的方法，但我不能让这些工作。

    任何人都可以帮助我吗？

    最佳答案

    我找到了解决方案。

    JBoss 强制我们定义一个 非 jta 数据源 如果我们不想使用事务或 jta-数据源如果你想使用它..

    无论我们是否想使用事务，问题是提供的大部分信息都建议我们用 指定这些。 jdbc/JNDI-NAME 当我们想要使用的是 java:/JNDI-NAME .

    总之，如果您想将 EclipseLink JPA 与 JBoss 而不是 Data-Source 一起使用，您需要确保指定:

  • transaction-type="RESOURCE_LOCAL"
  • <non-jta-data-source>java:/JNDI-NAME</non-jta-data-source>或 <jta-data-source>java:/JNDI-NAME</jta-data-source>

    • 这是我的persistence.xml的更正:
    <persistence-unit name="persistenceSamplePU" transaction-type="RESOURCE_LOCAL">     
     <non-jta-data-source>java:/EDeliveryUnit</non-jta-data-source>

     <!-- Entities must be specified for EclipseLink weaving -->
    <class>pt.inov.spocs.board.server.model.entity.SystemUser</class>
    <class>pt.inov.spocs.board.server.model.entity.UserSession</class>

    <properties>
        <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
        <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/edelivery_db" />
        <property name="javax.persistence.jdbc.user" value="root" />
        <property name="javax.persistence.jdbc.password" value="root" />
    </properties>
</persistence-unit>

    感谢您对@Chris 的宝贵帮助。

    关于jpa - 无法获取数据源。无法在 JBoss 5.1 中使用 JPA EntityManager (EclipseLink)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11566117/
