我注意到在使用spring-integration时将Spring-Boot从1.4.2升级到1.4.3时性能显着下降。
我可以使用以下程序重现该问题:
的pom.xml:

@ServiceActivator(inputChannel = "testChannel")
public void process(@Payload String payload) {
LOGGER.debug("payload: {}", payload);
}
}
IntegrationTest.java:

public class IntegrationTest {
private static final Logger LOGGER = LoggerFactory.getLogger(IntegrationTest.class);
@Autowired
private MessageChannel testChannel;
@Test
public void basic_test() {
for (int i = 1; i <= 10; i++) {
final long start = System.currentTimeMillis();
test(1000);
final long end = System.currentTimeMillis();
LOGGER.info("test run: {} took: {} msec", i, end - start);
}
}
private void test(int count) {
for (int i = 0; i < count; i++) {
testChannel.send(MessageBuilder.withPayload("foo").setHeader("monkey", "do").build());
}
}
}
当我使用Spring-Boot 1.4.2时,我得到以下结果:
2016-12-27 14:55:39.331 INFO 4939 --- [ main] performance.test.IntegrationTest : Started IntegrationTest in 0.975 seconds (JVM running for 1.52)

但是,当我使用Spring-Boot 1.4.3时,性能会有显着下降:

我不知道造成这种情况的原因是什么。 其他人是否有同样的问题?
答案 0 :(得分:3)
这可能与SPR-14929有关。
在这种情况下,从message参数中删除@Payload
可以解决问题(在这种情况下不需要它 - 如果有多个参数,则只需要有效负载注释)。
