未安装名为“org.mariadb.jdbc.Driver”的 JBOSS 驱动程序

问题描述

在 JBOSS7 中安装 MariaDB Java 连接器

我无法使用 MariaDB 在 JBOSS7 上部署 EJBCA 6。 我已将 EJBCA 配置为独立使用 JBOSS。 我的配置在使用默认 H2 数据库后端时有效。 我在 JBOSS standalone.xml 中配置了 mariadb Java 连接器

        <datasources>
            <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true">
                <connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1</connection-url>
                <driver>h2</driver>
                <security>
                    <user-name>sa</user-name>
                    <password>sa</password>
                </security>
            </datasource>
            <drivers>
                <driver name="h2" module="com.h2database.h2">
                    <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
                </driver>
                <driver name="mariadb" module="org.mariadb.jdbc">
                    <xa-datasource-class>org.mariadb.jdbc.MySQLDataSource</xa-datasource-class>
                </driver>
            </drivers>

            <datasource jndi-name="java:/MariaDS" pool-name="MariaDS" enabled="false">
                <connection-url>jdbc:mariadb://localhost:3306/ejbca</connection-url>
                <driver>mariadb</driver>
                <transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>
                <pool>
                    <min-pool-size>100</min-pool-size>
                    <max-pool-size>200</max-pool-size>
                </pool>
                <security>
                    <user-name>sa</user-name>
                    <password>sa</password>
                </security>
                <statement>
                    <prepared-statement-cache-size>100</prepared-statement-cache-size>
                    <share-prepared-statements/>
                </statement>
            </datasource>
        </datasources>

我已将 MariaDB Java 连接器复制到 JBOSS_HOME/modules/org/mariadb/jdbc/main/mariadb-java-client-1.1.5.jar 并像这样配置 module.xml：

    <?xml version="1.0" encoding="UTF-8"?>
    <module xmlns="urn:jboss:module:1.0" name="org.mariadb.jdbc">
      <resources>
        <resource-root path="mariadb-java-client-1.1.5.jar"/>
      </resources>
      <dependencies>
        <module name="javax.api"/>
        <module name="javax.transaction.api"/>
      </dependencies>
    </module>

MariaDB 驱动程序列在 boot.log 和 server.log 中。 它也通过 jboss-cli 列出：

    [standalone@localhost:9999 /] /subsystem=datasources:installed-drivers-list
    {
        "outcome" => "success",
        "result" => [
            {
                "driver-name" => "mariadb",
                "deployment-name" => undefined,
                "driver-module-name" => "org.mariadb.jdbc",
                "module-slot" => "main",
                "driver-datasource-class-name" => "",
                "driver-xa-datasource-class-name" =>         "org.mariadb.jdbc.MySQLDataSource",
                "driver-class-name" => "org.mariadb.jdbc.Driver",
                "driver-major-version" => 1,
                "driver-minor-version" => 1,
                "jdbc-compliant" => false
            },
            {
                "driver-name" => "h2",
                "deployment-name" => undefined,
                "driver-module-name" => "com.h2database.h2",
                "module-slot" => "main",
                "driver-datasource-class-name" => "",
                "driver-xa-datasource-class-name" => "org.h2.jdbcx.JdbcDataSource",
                "driver-class-name" => "org.h2.Driver",
                "driver-major-version" => 1,
                "driver-minor-version" => 3,
                "jdbc-compliant" => true
            }
        ]
    }

我已经像这样设置了 EJBCA database.properties：

    database.driver=org.mariadb.jdbc.Driver
    database.url=jdbc:mysql://hostname:3306/ejbca?characterEncoding=UTF
    database.name=mysql

但是，当我尝试使用 ant deploy 将 EJBCA 部署到 JBOSS 时，部署失败：

    jee:deployDSJBoss7:
         [exec] Result: 1
         [exec] Result: 1
         [echo] data-source add --name=ejbcads --driver-name="org.mariadb.jdbc.Driver" --connection-url="jdbc:mysql://ejbca-test-05.vm:3306/ejbca?characterEncoding=UTF-8" --jndi-name="java:/EjbcaDS"  --use-ccm=true --user-name="ejbca" --password="reverse" --validate-on-match=true --background-validation=false --prepared-statements-cache-size=50 --share-prepared-statements=true --min-pool-size=5 --max-pool-size=150 --pool-prefill=true --transaction-isolation=TRANSACTION_READ_COMMITTED --check-valid-connection-sql="select 1"
         [exec] JBAS010468: Driver named "org.mariadb.jdbc.Driver" is not installed.

我究竟做错了什么？

我看到一些奇怪的事情：

<datasource jndi-name="java:/MariaDS" pool-name="MariaDS" enabled="false">

enabled=false 不应该在那里或 true 像：

<datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true">

还有数据源元素和驱动程序元素也是很常见的。

对我来说，在搜索了很多东西并收集了一些零碎的东西之后，下面的工作

首先需要通过 jboss-cli 部署 Mariadb jar 文件，然后在 org/mariadb/main/ 下添加模块

<?xml version="1.0" encoding="UTF-8"?> <module xmlns="urn:jboss:module:1.1" name="org.mariadb">  <resources>   <resource-root path="mariadb-java-client-2.7.0.jar"/></resources>  <dependencies>   <module name="javax.api"/>   <module name="javax.transaction.api"/>   </dependencies> </module>

然后在 standalone.xml 中添加更改

<datasource jta="true" jndi-name="java:jboss/MariaDBDS" pool-name="MariaDBDS" enabled="true" use-ccm="false">
                <connection-url>jdbc:mariadb://localhost:3306/DbName</connection-url>
                <driver>mariadb-java-client-2.7.0.jar</driver>
                <driver-class>org.mariadb.jdbc.Driver</driver-class>
                
                <security>
                    <user-name>uname</user-name>
                    <password>pwd</password>
                </security>
                <validation>
                    <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLValidConnectionChecker"/>
                    <validate-on-match>true</validate-on-match>
                    <background-validation>false</background-validation>
                    <exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLExceptionSorter"/>
                </validation>
            </datasource>
