将 JPA (EclipseLink) 放在 JBoss 服务器中工作时，我遇到了很多困难。我通常使用Tomcat，它很简单......

  1. 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>
  1. 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 中出现了这些错误：

我尝试了许多不同的方式，但我无法让这些工作。

任何人都可以帮助我吗？

我找到了解决方案。

如果我们不想使用事务，JBoss 强制我们定义一个非 jta- data-source，如果你想使用它，则强制我们定义一个 jta-data-source。

无论哪种方式，无论我们是否要使用事务，问题是提供的大多数信息都建议我们使用jdbc/JNDI-NAME来指定这些，而我们要使用的是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>或者<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>

感谢您的宝贵帮助@Chris。

您正在指定不与数据源混合的“javax.persistence.jdbc.x”属性。您应该指定要使用的数据源或 JDBC 连接 url 等，但不能同时指定两者。您是否尝试使用 JTA？还有一个警告，说明您正在使用定义了 JTA 数据源的 transaction-type="resource-local" - 您需要为要使用的 JTA 数据源指定“JTA”事务类型，并且需要它以便它可以挂钩到 JBoss 事务管理器。数据源查找可能还需要设置目标服务器。

我知道这可能是旧的。我在 jdeveloper 12c 和 weblogic 12.x 上遇到了同样的问题，我通过省略java: from datasource name at persistence.xml 文件解决了这个问题，如下所示：from: java:/app/jdbc/data_source

到： /app/jdbc/data_source
