Java 如何使用apache camel sqlComponent运行sql查询

您好，我是apache camel框架的新手（因此我编写的代码很可能非常糟糕：）。我想连接到本地数据库并运行sql查询，然后在控制台中显示结果。到目前为止，我有：

import javax.sql.DataSource;
import org.apache.camel.CamelContext;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.impl.DefaultCamelContext;
import org.apache.camel.impl.SimpleRegistry;
import org.apache.commons.dbcp2.BasicDataSource;

public class sqlENEIA3 {

public static void main(String[] args) throws Exception {
            String url = "jdbc:oracle:thin:@localhost:1521:ENETEST";
            DataSource dataSource = setupDataSource(url);

            SimpleRegistry reg = new SimpleRegistry();
            reg.put("myDataSource",dataSource);
            CamelContext context = new DefaultCamelContext(reg);    
            context.addRoutes(new sqlENEIA3().new MyRouteBuilder());


            context.start();
            Thread.sleep(5000);
            context.stop();

        }


          class MyRouteBuilder extends RouteBuilder {


            public void configure() {
            from("timer://Timer?period=60000").to("sql:select * from projects").to("stream:out");


            }
          } 

        private static DataSource setupDataSource(String connectURI) {
            BasicDataSource ds = new BasicDataSource();
            ds.setDriverClassName("org.apache.commons.dbcp.BasicDataSource"); 
            ds.setUsername("System");
            ds.setPassword("Igor_1");
            ds.setUrl(connectURI);
            return ds;
    }
  }

我收到的错误消息如下：

线程“main”org.apache.camel.FailedToCreateRouteException中出现异常：未能在以下位置创建路由route1:>>>到[sql:select*from projects]您必须配置数据源：

from("timer://Timer?period=60000")
.to("sql:select * from projects?dataSource=myDataSource")
.to("stream:out");

您可以使用sql组件，如轮询消费者（不需要使用计时器）。可以在此处找到更多信息：（）

更新1:

尝试使用数据源，如下所示：

<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
  <property name="driverClassName" value= "oracle.jdbc.pool.OracleDataSource" />
  <property name="url" value="jdbc:oracle:thin:@localhost:1521:ENETEST" />
  <property name="username" value="System" />
  <property name="password" value="Igor_1" />
  <property name="maxIdle" value="1" />
</bean>

Tx用于重播。但现在我有另一个错误：）org.springframework.jdbc.CannotGetJdbcConnectionException:无法获取jdbc连接；嵌套异常是java.sql.SQLException：无法加载JDBC驱动程序类“org.apache.commons.dbcp.BasicDataSource”，我正在使用Maven
