我正在使用Wildfly 10.起初我尝试通过CLI创建数据源.

命令部署mysql-connector-java-6.0.4.jar执行得很好.
/ subsystem = datasources：installed-drivers-list显示已安装驱动程序

{
    "driver-name" => "mysql-connector-java-6.0.4.jar",
    "deployment-name" => "mysql-connector-java-6.0.4.jar",
    "driver-module-name" => undefined,
    "module-slot" => undefined,
    "driver-datasource-class-name" => undefined,
    "driver-xa-datasource-class-name" => undefined,
    "driver-class-name" => "com.mysql.cj.jdbc.Driver",
    "driver-major-version" => 6,
    "driver-minor-version" => 0,
    "jdbc-compliant" => false
}

但数据源不是使用命令创建的

data-source add --name=zktest-datasource
--jndi-name=java:/jdbc/zktest-database --driver-name=mysql-connector-java-6.0.4.jar --connection-url=jdbc:mysql://localhost:3306/zktest --user-name=root --password=111

连接测试

/subsystem=datasources/data-source=zktest-datasource:test-connection-in-pool
was failed.

现在我尝试使用standalone.xml创建数据源

我的modules.xml

<module xmlns="urn:jboss:module:1.1" name="com.mysql.jdbc">
  <resources>
    <resource-root path="mysql-connector-java-6.0.4.jar">
  </resource-root>
  </resources>
  <dependencies>
    <module name="javax.api"></module>
    <module name="javax.transaction.api"></module>
  </dependencies>
</module>

modules.xml放在JBOSS_HOME / modules / system / layers / base / com / mysql / jdbc中

JBOSS_HOME / standalone / configuration / standalone.xml中的“Datasources”部分

<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;DB_CLOSE_ON_EXIT=FALSE</connection-url>
            <driver>h2</driver>
            <security>
                <user-name>sa</user-name>
                <password>sa</password>
            </security>
        </datasource>
        <datasource jndi-name="java:jboss/datasources/MySqlDS" pool-name="MySqlDS" enabled="true" use-java-context="true">
            <connection-url>jdbc:mysql://localhost:3306/zktest</connection-url>
            <driver>mysql</driver>
            <security>
                <user-name>root</user-name>
                <password>111</password>
            </security>
        </datasource>
        <drivers>
            <driver name="h2" module="com.h2database.h2">
                <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
            </driver>
            <driver name="mysql" module="com.mysql.jdbc">
                <xa-datasource-class>com.mysql.cj.jdbc.Driver</xa-datasource-class>
            </driver>
        </drivers>
    </datasources> 

现在,虽然deploing我看到这样的消息

WFLYCTL0184: New missing/unsatisfied dependencies:
service jboss.jdbc-driver.mysql (missing) dependents: [service jboss.driver-demander.java:jboss/datasources/MySqlDS, service
org.wildfly.data-source.MySqlDS]

在Wildfly控制面板中进行测试连接时：

{
“outcome” => “failed”,
“failure-description” => “WFLYJCA0040: failed to invoke operation: WFLYJCA0042: failed to match pool. Check JndiName:
java:jboss/datasources/MySqlDS”,
“rolled-back” => true }

解决方法:

通过将驱动程序更改为mysql-connector-java-5.1.38.jar解决了问题.
我删除了旧驱动程序,然后在CLI中执行了以下步骤：

module add --name=com.mysql.jdbc --resources=mysql-connector-java-5.1.38.jar --dependencies=javax.api,javax.transaction.api

/subsystem=datasources/jdbc-driver=mysql:add(driver-name="mysql",driver-module-name="com.mysql.jdbc",driver-class-name=com.mysql.jdbc.Driver)

data-source add --name=MySQLDS --driver-name=mysql --connection-url=jdbc:mysql://localhost:3306/zktest --jndi-name=java:jboss/jdbc/MySQLDS --user-name=username --password=password

data-source enable --name=MySQLDS
