spring-boot-starter-integration 1.4.3性能下降

Question

我注意到在使用彈簧集成的同時將Spring-Boot從1.4.2升級到1.4.3時性能顯着下降。

我可以用下面的程序重現該問題：

的pom.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

     <version>1.4.3.RELEASE</version> 
    </parent> 

    <artifactId>performance-test</artifactId> 
    <version>1.0-SNAPSHOT</version> 

    <dependencies> 
     <dependency> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-starter-integration</artifactId> 
     </dependency> 
     <dependency>

      <artifactId>spring-boot-starter-test</artifactId> 
      <scope>test</scope> 
     </dependency> 
    </dependencies> 

</project> 

Application.java：

package performance.test; 

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 

@SpringBootApplication 
public class Application { 

    public static void main(final String[] args) { 
     SpringApplication.run(Application.class, args); 
    } 
} 

UsersManager.java：

package performance.test; 

import org.slf4j.Logger; 
import org.slf4j.LoggerFactory; 
import org.springframework.integration.annotation.MessageEndpoint; 
import org.springframework.integration.annotation.ServiceActivator; 
import org.springframework.messaging.handler.annotation.Payload; 

@MessageEndpoint 
public class UsersManager { 

    private static final Logger LOGGER = LoggerFactory.getLogger(UsersManager.class); 

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

集成Test.java：

package performance.test; 

import org.junit.Test; 
import org.junit.runner.RunWith; 
import org.slf4j.Logger; 
import org.slf4j.LoggerFactory; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.boot.test.SpringApplicationConfiguration; 
import org.springframework.messaging.MessageChannel; 
import org.springframework.messaging.support.MessageBuilder; 
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; 

@RunWith(SpringJUnit4ClassRunner.class) 
@SpringApplicationConfiguration(classes = Application.class) 
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()); 
     } 
    } 
} 

當我使用Spring-引導1.4.2，我得到如下結果：

然而，當我使用Spring-引導1.4.3，有顯著的性能降解：

我不知道可能是什麼原因造成的。 其他人是否有同樣的問題？

Answer 1

這可能與SPR-14929有關。

在這種情況下，從消息參數中刪除@Payload可解決問題（在這種情況下不需要 - 如果有多個參數，則只需要有效載荷註釋）。
