How to implement an Oracle AQ queue in Spring Boot?
I already found out how to create an Oracle database with AQ (Streams?) packages. I also created some queue's in Oracle (by hand). (Using PL/SQL and SQL).
However, I'm having a hard time setting up a proper connection from Spring.
The following works (using oracle.AQ java package):
private final String aqUrl = "jdbc:oracle:thin:@localhost:1521:orcl";
private final String aqUser = "queue_mut";
private final String aqPassword = "******";
private final String aqSchema = "queue_mut";
private final String aqTable = "aq_table1";
private final String aqQueue = "aq_queue1";
@Test
public void testManualAQ() throws ClassNotFoundException, SQLException, AQException {
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection connection = DriverManager.getConnection(aqUrl, aqUser, aqPassword);
connection.setAutoCommit(false);
Class.forName("oracle.AQ.AQOracleDriver");
AQSession aqSession = AQDriverManager.createAQSession(connection);
AQQueueTable q_table = aqSession.createQueueTable(aqSchema, aqTable, new AQQueueTableProperty("RAW"));
aqSession.createQueue(q_table, aqQueue, new AQQueueProperty());
}
(based on https://docs.oracle.com/cd/B10501_01/appdev.920/a96587/apexampl.htm)
This shows me that I can connect to Oracle and reach AQ functionality.
Now, I'm trying to create Java Configured beans in order to use the JmsTemplate.
@Resource
private JmsTemplate jmsTemplate;
@Test
public void testJmsTemplate() {
String xmlval = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" +
"<product id=\"10\">\n" +
" <description>Foo</description>\n" +
" <price>2.05</price>\n" +
"</product>";
jmsTemplate.convertAndSend(aqSchema + ".jms_ws_incoming_queue", xmlval);
}
(yes, the queue already exists ;-))
With the following configuration class:
import oracle.jms.AQjmsFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.jms.core.JmsTemplate;
import javax.jms.ConnectionFactory;
import javax.jms.JMSException;
import javax.sql.DataSource;
@Configuration
public class OracleAQConfiguration {
@Bean
public DataSourceTransactionManager transactionManager(DataSource dataSource) {
DataSourceTransactionManager manager = new DataSourceTransactionManager();
manager.setDataSource(dataSource);
return manager;
}
@Bean
public ConnectionFactory connectionFactory(DataSource dataSource) throws JMSException {
return AQjmsFactory.getQueueConnectionFactory(dataSource);
}
@Bean
public JmsTemplate jmsTemplate(ConnectionFactory connectionFactory) {
JmsTemplate jmsTemplate = new JmsTemplate();
jmsTemplate.setSessionTransacted(true);
jmsTemplate.setConnectionFactory(connectionFactory);
return jmsTemplate;
}
}
And with properties yml:
spring:
datasource:
url: jdbc:oracle:thin:@localhost:1521:orcl
username: queue_mut
password: ******
driverClassName: oracle.jdbc.driver.OracleDriver
But with this I get errors which I cannot grasp:

I believe that the Cast exception occurs because it is a ProxyConnection[PooledConnection[oracle.jdbc.driver.T4CConnection@40016ce1]]. But I don't know how to fix this.
Answer
Change the jdbc library, in my case this fixed it(if don't, try with some other versions):
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc7</artifactId>
<version>12.1.0.2.0</version>
</dependency>
