我已经在Wildfly中搜索了创建数据源的替代方法,但我没有找到以编程方式创建数据源的替代方法,是否可能?
答案 0 :(得分:3)
以下示例使用JBoss-EAP 7.0(使用Wildfly)进行测试。 Pure Wildfly可能具有不同的maven依赖关系,提供ModelControllerClient
。此示例使用以下Maven依赖关系(来自存储库https://maven.repository.redhat.com/ga):
<dependency>
<groupId>org.wildfly.core</groupId>
<artifactId>wildfly-controller-client</artifactId>
<version>2.1.13.Final-redhat-1</version>
</dependency>
我假设您已经手动配置了数据源并且驱动程序模块已就位jboss/modules/system/layers
,以下示例使用MySQL
驱动程序。将驱动程序添加到JBoss配置中
你必须执行以下代码:
ModelControllerClient client = ModelControllerClient.Factory.create(InetAddress.getByName("localhost"), 9990);
ModelNode request = new ModelNode();
request.get(ClientConstants.OP).set(ClientConstants.ADD);
request.get(ClientConstants.OP_ADDR).add("subsystem","datasources");
request.get(ClientConstants.OP_ADDR).add("jdbc-driver","mysql");
request.get("driver-name").set("mysql");
request.get("driver-module-name").set("com.mysql");
request.get("driver-xa-datasource-class-name").set("com.mysql.jdbc.jdbc2.optional.MysqlXADataSource");
client.execute(new OperationBuilder(request).build());
client.close();
这会将驱动程序添加到您的配置中:
<driver name="mysql" module="com.mysql">
<xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
</driver>
添加数据源与添加驱动程序非常相似:
ModelControllerClient client = ModelControllerClient.Factory.create(InetAddress.getByName("localhost"), 9990);
ModelNode request = new ModelNode();
request.get(ClientConstants.OP).set(ClientConstants.ADD);
request.get(ClientConstants.OP_ADDR).add("subsystem","datasources");
request.get(ClientConstants.OP_ADDR).add("data-source","TestDs");
request.get("jta").set(true);
request.get("jndi-name").set("java:jboss/datasources/TestDs");
request.get("pool-name").set("TestDs");
request.get("use-java-context").set(true);
request.get("use-ccm").set(true);
request.get("connection-url").set("jdbc:mysql://localhost/test");
request.get("driver-name").set("mysql");
request.get("transaction-isolation").set("TRANSACTION_READ_COMMITTED");
request.get("min-pool-size").set(5);
request.get("max-pool-size").set(20);
request.get("pool-prefill").set(true);
request.get("pool-use-strict-min").set(false);
request.get("flush-strategy").set("FailingConnectionOnly");
request.get("user-name").set("test");
request.get("password").set("test");
request.get("prepared-statements-cache-size").set(32);
request.get("share-prepared-statements").set(true);
client.execute(new OperationBuilder(request).build());
client.close();
使用此代码,以编程方式创建数据源:
<datasource jta="true" jndi-name="java:jboss/datasources/TestDs" pool-name="TestDs" use-java-context="true" use-ccm="true">
<connection-url>jdbc:mysql://localhost/test</connection-url>
<driver>mysql</driver>
<transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>
<pool>
<min-pool-size>5</min-pool-size>
<max-pool-size>20</max-pool-size>
<prefill>true</prefill>
<use-strict-min>false</use-strict-min>
<flush-strategy>FailingConnectionOnly</flush-strategy>
</pool>
<security>
<user-name>test</user-name>
<password>test</password>
</security>
<statement>
<prepared-statement-cache-size>32</prepared-statement-cache-size>
<share-prepared-statements>true</share-prepared-statements>
</statement>
</datasource>
