如何将Spring Boot JMS从ActiveMQ迁移到Oracle Advanced Queuing

Question

我正在研究Spring Boot和JMS的例子，是的，我对此很新

由于我们使用Oracle，因此我想将Spring Boot和JMS示例从ActiveMQ迁移到Oracle Advanced Queuing。 但是我真的很少发现这方面的信息。

据我所知，我需要为Oracle版本替换下面的代码，但我没有设法找到方法。

@Bean
public JmsListenerContainerFactory<?> myFactory(ConnectionFactory connectionFactory,
                                                DefaultJmsListenerContainerFactoryConfigurer configurer) {
    DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
    // This provides all boot's default to this factory, including the message converter
    configurer.configure(factory, connectionFactory);
    // You could still override some of Boot's default if necessary.
    return factory;

}

原始代码可以在Github找到

非常感谢帮助！

下面的配置将解决您的问题。

1 - 创建配置 。 对于这个答案，我已将所有配置文件压缩到应用程序文件中。 你可以将它们放在单独的类中，从而分散关注点。

@SpringBootApplication
@EnableJms
public class Application {
    private static Random rand = new Random();

    @Bean
    DataSource dataSource() throws SQLException {
        OracleDataSource dataSource = new OracleDataSource();
        dataSource.setUser("yourusername");
        dataSource.setPassword("yourpassword");
        dataSource.setURL("jdbc:oracle:thin:@yourserver:1521:xe");
        dataSource.setImplicitCachingEnabled(true);
        dataSource.setFastConnectionFailoverEnabled(true);
        return dataSource;
    }    

    @Bean
    public QueueConnectionFactory connectionFactory() throws Exception {
        return AQjmsFactory.getQueueConnectionFactory(dataSource());
    }

    @Bean
    public JmsTemplate jmsTemplate() throws Exception {
        JmsTemplate jmsTemplate = new JmsTemplate();
        jmsTemplate.setConnectionFactory(connectionFactory());
        jmsTemplate.setMessageConverter(jacksonJmsMessageConverter());
        return jmsTemplate;
    }

    @Bean
    public JmsListenerContainerFactory<?> myJMSListenerFactory(QueueConnectionFactory connectionFactory,                                                      DefaultJmsListenerContainerFactoryConfigurer configurer) {
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        //  factory.setConcurrency("15-20");
        factory.setMessageConverter(jacksonJmsMessageConverter());
        configurer.configure(factory, connectionFactory);
        return factory;
    }

    @Bean
    public MessageConverter jacksonJmsMessageConverter() {
        MappingJackson2MessageConverter converter = new MappingJackson2MessageConverter();
        converter.setTargetType(MessageType.TEXT);
        converter.setTypeIdPropertyName("_type");
        return converter;
    }

    public static void main(String[] args) {
        ConfigurableApplicationContext context = SpringApplication.run(Application.class, args);
        JmsTemplate jmsTemplate = context.getBean(JmsTemplate.class);
        for (int i = 0; i < 10; i++) {
            int waitSecs = rand.nextInt(3);
            jmsTemplate.convertAndSend("YourQueueName", new Email("info@example.com", "Hello " + i, waitSecs));
        }
    }
}

2 - 创建JMS侦听器

@Component
public class Receiver {
    @JmsListener(destination = "YourQueueName", containerFactory = "myJMSListenerFactory")
    public void receiveEmail(Email email) {
        System.out.println("Received <" + email + ">");
    }
}

3 - Maven和Oracle

您可以在ORACLE6或Oracle7的罐子另加到库的路径，如图这篇文章 。

Mavan文件的其余部分非常标准。

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <java.version>1.8</java.version>
    </properties>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.2.RELEASE</version>
    </parent>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-activemq</artifactId>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>3.8.1</version>
            <scope>test</scope>
        </dependency>
    </dependencies>
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

4 - 业务对象 。 像电子邮件这样的对象是您的业务领域POJO。 我不会把它们放在这里。

@Testing，这就像魅力;-)

我不认为您需要更改myFactory方法，而是需要创建连接到oracle队列的connectionFactory。 我有类似的配置，在开发中我使用artemis来运行我的JUNIT而在prod中我使用了oracle队列。 下面是我为创建connectionFactory定义的类。

并且您需要将wlthint3client添加到类路径中。 我从<weblogic_home>\\wlserver\\server\\lib获取了jar，并从jar创建了maven依赖，并将其推送到我的本地repo并将jar添加为依赖项。

    <dependency>
        <groupId>com.oracle.weblogic</groupId>
        <artifactId>wlthint3client</artifactId>
        <version>12.2.1</version>
        <scope>provided</scope> <!-- comment out this if you are deploying on tomcat or running the application standalone -->
    </dependency>
