没有为jdbc找到合适的驱动程序：mysql：// localhost / <mydb>

标签： java mysql jpa jax-rs wildfly-10

我正在使用Jax-RS和JPA创建测试应用程序。我试图在de Jax-RS资源中实例化EntityManaget时遇到问题。

我尝试使用Wildfly 10作为Application Server，但是这个错误也发生在Glassfish 4.1.1上。

不确定它是否相关，但我使用的是Intellij和maven。由于我的目标是仅使用JavaEE规范，因此我添加了java ee api maven dependecy，以便使用Application Server库。

有人有想法吗？ 谢谢！

我试图让我的应用程序管理连接，而不是容器。

你做的与我有点不同，但我认为这仍然有用。最终，您需要注册JDBC驱动程序。在Wildfly中，我使用jboss-cli命令（位于Wildfly bin目录中）。我安装JDBC驱动程序，如：

jboss-cli.sh --connect --command="module add --name=org.postgres --resources=jdbc_driver.jar --dependencies=javax.api,javax.transaction.api"
jboss-cli.sh --connect --command='/subsystem=datasources/jdbc-driver=mysql:add(driver-name="mysql",driver-module-name="com.mysql",driver-class-name=com.mysql.jdbc.Driver)'
jboss-cli.sh --connect --command="data-source add --jndi-name=java:/jdbc/sistema_ser --name=yourPoolName --connection-url=jdbc:mysql://localhost/sistema_ser --driver-name=mysql --user-name=root --password=root"

然后，在persistence.xml中我有：

<persistence-unit name="sistema_ser" transaction-type="JTA">
    <jta-data-source>jdbc/sistema_ser</jta-data-source>

同样，最终你需要向Wildfly注册驱动程序。

答案 1 :(得分：0)

将以下内容添加到persistence.xml文件中：

<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
