Apache ActiveMQ Camel事务回滚

[英]Apache ActiveMQ Camel transacted rollback

为了更好地理解ActiveMQ和Camel,我正在为事务回滚编写单元测试。 它似乎不适合我,这意味着我做错了什么! 这是代码:

public class MyTest extends CamelTestSupport {
@Override
protected JndiRegistry createRegistry() throws Exception {
    JndiRegistry reg = super.createRegistry();

    DataSourceTransactionManager txMgr = new DataSourceTransactionManager();

    SpringTransactionPolicy txPolicy = new SpringTransactionPolicy();
    txPolicy.setTransactionManager(txMgr);
    txPolicy.setPropagationBehaviorName("PROPAGATION_REQUIRED");
    reg.bind("required", txPolicy);

    return reg;
}

@Before
public void setUp() throws Exception {
    super.setUp();
}

@After
public void tearDown() throws Exception {
    super.tearDown();
}

@Test
public void testTransaction() throws Exception {
    ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("vm://localhost?broker.persistent=false");
    context.addComponent("jms", JmsComponent.jmsComponentTransacted(connectionFactory));
    context.addRoutes(new RouteBuilder() {
        @Override
        public void configure() throws Exception {
            from("jms:queue:in")
                    .transacted("required")
                    .process(new Processor() {
                        @Override
                        public void process(Exchange exchange) throws Exception {
                            System.out.println("Expected failure");
                            throw new RuntimeException("Expected failure");
                        }
                    })
                    .to("mock:result");
        }
    });
    context.start();

    MockEndpoint result = context.getEndpoint("mock:result", MockEndpoint.class);
    result.expectedMessageCount(0);

    NotifyBuilder notifyBuilder = new NotifyBuilder(context).whenDone(1).create();
    context.createProducerTemplate().sendBody("jms:queue:in", "Test");

    boolean matches = notifyBuilder.matches(5, TimeUnit.SECONDS);
    assertTrue(matches);

    Thread.sleep(1000);
    assertMockEndpointsSatisfied();

    BrowsableEndpoint in = context.getEndpoint("jms:queue:in", BrowsableEndpoint.class);
    List<Exchange> list = in.getExchanges();
    assertEquals(1, list.size());
    String body = list.get(0).getIn().getBody(String.class);
    assertEquals("Test", body);

    context.stop();
}

}

它在list.size()为1的断言上失败,如果回滚成功则应该通过该断言。 我究竟做错了什么? 提前致谢!

在您的情况下,当您需要的是引用您的ConnectionFactoryorg.springframework.jms.connection.JmsTransactionManager ,您正在使用DataSourceTransactionManager 也可以将?transacted=true添加到JMS URI而不是引用事务管理器 - 这使用本地JMS事务。

在这两种情况下,默认情况下会发生的消息是,消息将在ActiveMQ中的死信队列中结束,而不是在原始队列中。 可以配置此行为。
