Question

我正在使用：

TomEE 7.0 + EclipseLink + Vaadin（+ Vaadin JPA）+ Maven

当我在Eclipse内的服务器上运行我的应用程序时，TomEE忽略persistence.xml中定义的数据库参数。即使我定义了eclipselink.target-database属性

，它也总是使用内置的HSQL数据库引擎

的persistence.xml ：

 <persistence-unit name="OFFERTER_JPA"
    transaction-type="RESOURCE_LOCAL">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    <non-jta-data-source>OFFERTER_DS</non-jta-data-source>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <properties>
        <property name="eclipselink.target-database" value="org.eclipse.persistence.platform.database.PostgreSQLPlatform"/>
        <property name="javax.persistence.jdbc.url" value="jdbc:postgresql://localhost:5432/oferter" />
        <property name="javax.persistence.jdbc.driver" value="org.postgresql.Driver" />
        <property name="javax.persistence.jdbc.user" value="oferter" />
        <property name="javax.persistence.jdbc.password" value="oferter" />
        <property name="eclipselink.logging.level" value="ALL" />
    </properties>
</persistence-unit>

控制台上的结果显示TomEE 读取参数并尝试创建连接但因此连接到HSQL 而不是PostgreSQL：

有什么奇怪的。 如果我使用Eclipse中的Export -> WAR file将应用程序导出到独立的.WAR 并在同一个TomEE实例上手动部署，它的行为正确且连接到PostgreSQL < / p>

此处描述了类似的问题：

The same problem description - no solution

Answer 1

创建/WEB-INF/resources.xml

<?xml version="1.0" encoding="UTF-8"?>
<tomee>

  <Resource id="myDS" type="DataSource">
    JdbcDriver  = org.postgresql.Driver
    JdbcUrl = jdbc:postgresql://112.216.148.236:5432/ncore
    UserName  =  xxx
    Password  = xxx
</Resource>
</tomee>

然后尝试

Eclipse中的TomEE始终使用HSQL数据库引擎而不是在persistence.xml（EclipseLink）中定义
