java无法在Jboss EAP 7.0服务器中创建oracle数据源

Question

我需要在JBOSS EAP 7.0服务器中创建一个oracle数据源

我部署了ojdbc6。使用以下命令从JBOSS管理CLI（命令行界面）获取jar

deploy <PATH_TO_ORACLE_DRIVER_JAR>

部署驱动程序后，我可以看到服务器日志，如下所示

01:25:53,338 INFO  [org.jboss.as.connector.deployers.jdbc] (MSC service thread 1-1) WFLYJCA0018: Started Driver service with driver-name = ojdbc6.jar
01:25:53,747 INFO  [org.jboss.as.server] (management-handler-thread - 6) WFLYSRV0010: Deployed "ojdbc6.jar" (runtime-name : "ojdbc6.jar")

但是当我试图从Jboss管理控制台创建oracle数据源（oracle.jdbc.driver.OracleDriver作为驱动程序类）时，我得到了以下错误

01:31:35,084 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 66) WFLYCTL0013: Operation ("add") failed - address: ([
    ("subsystem" => "datasources"),
    ("data-source" => "OracleDS")
]) - failure description: {"WFLYCTL0180: Services with missing/unavailable dependencies" => [
    "jboss.driver-demander.java:/OracleDS is missing [jboss.jdbc-driver.oracle]",
    "org.wildfly.data-source.OracleDS is missing [jboss.jdbc-driver.oracle]"
]}

      service jboss.jdbc-driver.oracle (missing) dependents: [service jboss.driver-demander.java:/OracleDS, service org.wildfly.data-source.OracleDS]

1）我可以知道是什么导致了这个问题吗？缺少什么依赖关系
2） 将JDBC驱动程序作为数据源创建的JAR部署安装是否正确

Answer 1

安装一个JDBC驱动程序作为核心模块

• 在$JBOSS_HOME/modules下创建一个目录。在本例中：“$JBOSS_HOME/modules/com/oracle/jdbc/main”

• 将JDBC驱动程序jar（ojdbc6.jar）的文件放在这个目录中

• 创建模块配置文件模块。xml:

示例Oracle JDBC驱动程序模块。xml文件

<?xml version="1.0" ?>
<module xmlns="urn:jboss:module:1.1" name="com.oracle">
    <resources>
        <resource-root path="ojdbc6.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <module name="javax.transaction.api"/>
    </dependencies>
</module>

Oracle数据源配置示例

<datasources>
  <datasource jndi-name="java:jboss/OracleDS" pool-name="OracleDS">
    <connection-url>jdbc:oracle:thin:@localhost:1521:XE</connection-url>
    <driver>oracle</driver>
    <security>
        <user-name>admin</user-name>
        <password>admin</password>
    </security>
    <validation>
        <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleValidConnectionChecker"/>
        <validate-on-match>true</validate-on-match>
        <background-validation>false</background-validation>
        <stale-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleStaleConnectionChecker"/>
        <exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.oracle.OracleExceptionSorter"/>
    </validation>
  </datasource>
  <drivers>
    <driver name="oracle" module="com.oracle">
        <xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
    </driver>
  </drivers>
</datasources>

示例管理CLI命令

此示例配置可以通过使用以下管理CLI命令来实现

1#添加Oracle JDBC驱动程序作为核心模块

模块add name=com。oracle资源=/path/to/misc/jdbc_drivers/oracle/ojdbc7。jar dependencies=javax。api，javax。交易api

2#注册Oracle JDBC驱动程序

/subsystem=datasources/jdbc driver=oracle:add（driver name=oracle，driver module name=com.oracle，driver xa datasource class name=oracle.jdbc.xa.client.oraclexadasource）

3#添加Oracle数据源

数据源add name=OracleDS jndi name=java:jboss/OracleDS driver name=oracle connection url=jdbc:oracle:thin:@localhost:1521:XE user name=admin password=admin validate on match=true background validation=false valid connection checker class name=org。jboss。jca。适配器。jdbc。扩展。神谕OracleValidConnectionChecker异常分类器类名=org。jboss。jca。适配器。jdbc。扩展。神谕OracleExceptionSorter旧连接检查器类名=org。jboss。jca。适配器。jdbc。扩展。神谕OracleStaleConnectionChecker
