jpa - 错误新的缺失/不满足的依赖项 : (Cannot configure datasource)

Question

我有一个使用 JSF(Primefaces)、JPA(Hibernate) 和 EJB 的 Web 应用程序，但无法在 JBoss 上配置数据源。我收到以下错误:

2012/10/31 07:20:17,948 INFO  [org.jboss.as.connector.deployers.jdbc] (MSC service thread 1-3) JBAS010404: Deploying non-JDBC-compliant driver class com.mysql.jdbc.Driver (version 5.1)

您可以在下面看到我的 persistence.xml、stanadlone.xml 和 pom.xml。 我是否缺少 pom.xml 中的某些依赖项？

Persistence.xml

谁能告诉我我做错了什么？

Answer 1

您是否启用了 mysql 数据源？默认情况下它是禁用的。

部分配置

<datasource jndi-name="java:jboss/datasources/MysqlDS" enabled="${mysql.enabled}" use-java-context="true" pool-name="MysqlDS">

具有标志 ${mysql.enabled} 是系统属性，如果启用了 mysql，则启用数据源。

看看指南http://jaitechwriteups.blogspot.com/2011/08/deploy-java-ee-application-on-openshift.html

并搜索“使用 OpenShift Express 中可用的 MySQL 数据库”一章

向您显示您缺少配置的哪一部分。
