Question

我正在尝试使用@DataSourceDefinition-Annotation部署数据源。

当wildfly部署jar时，它会抛出ClassNotFoundException。

我把mysql-jdbc-Driver放在deployment-directory中。我已经在standalone.xml中配置的数据源中使用了com.mysql.jdbc.Driver类。我没有在“modules \ system \ layers \ base”

下创建一个带有jdbc-driver的模块

这是带注释的类：

@Stateless
@DataSourceDefinition(name = "java:global/jdbc/testingDS",
    className = "com.mysql.jdbc.Driver",
    portNumber = 3306,
    serverName = "localhost",
    databaseName = "testing",
    user = "testing",
    password = "testing")

public class DataSourceDeployment {
  public void someMethod() { }
}

这是Exception（这是* .failed-File）：

{
    "JBAS014671: Failed services" => {"jboss.deployment.unit.\"DatasourceDeploymentTest-1.jar\".INSTALL" => "org.jboss.msc.service.StartException in service jboss.deployment.unit.\"DatasourceDeploymentTest-1.jar\".INSTALL: JBAS018733: Failed to process phase INSTALL of deployment \"DatasourceDeploymentTest-1.jar\"

    ]
}

CFNE就是应有的。

你在模块中有mysql jdbc驱动程序，但你的部署和它@DataSourceDefinition知道它。

@DataSourceDefinition使用部署类加载器加载jdbc驱动程序，但它不可用，因为它在模块中。

要解决此问题，您应该

1）通过manifest.mf / jboss-deployment-structure.xml将部署依赖项添加到mysql驱动程序模块，有关详细信息，请参阅https://docs.jboss.org/author/display/WFLY8/Class+Loading+in+WildFly

2）将jdbc驱动程序添加到war的lib目录

但我绝对会选择1）

尝试使用@DataSourceDefinition部署DataSource时ClassNotFoundException
