性能大比拼

一、創建euraka集羣

創建父項目，包含父pom文件和子項目，並增加依賴，主要是：spring-cloud-starter-parent

<parent>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-parent</artifactId>
    <version>Camden.RELEASE</version>
</parent>
<groupId>com.sohu.tv</groupId>
<artifactId>spring-cloud-test</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>

<modules>
    <module>eureka-test</module>
    <module>provider-test</module>
    <module>consumer-test</module>
</modules>

創建eureka-test，並在pom添加依賴spring-cloud-starter，spring-cloud-starter-eureka-server

<parent>
    <groupId>com.sohu.tv</groupId>
    <artifactId>spring-cloud-test</artifactId>
    <version>1.0-SNAPSHOT</version>
</parent>

<artifactId>eureka-test</artifactId>
<packaging>jar</packaging>

<dependencies>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-eureka-server</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

euraka代碼很簡單：

@SpringBootApplication
@EnableEurekaServer
public class SpringCloudEurekaApplication {
    public static void main(String[] args) {
        SpringApplication.run(SpringCloudEurekaApplication.class, args);
    }
}

euraka-test配置application.yml

spring: 
  application:
    name: eureka-test

server: 
  port: 8000

eureka:
  instance:
    preferIpAddress: true
    instanceId: ${spring.cloud.client.ipAddress}:${server.port}
---

spring: 
  profiles: node1

eureka: 
  client: 
    serviceUrl:
      defaultZone: http://eureka:8000/eureka/,http://eureka2:8000/eureka/

---

spring: 
  profiles: node2

eureka: 
  client:
    serviceUrl:
      defaultZone: http://eureka2:8000/eureka/,http://eureka3:8000/eureka/

---

spring: 
  profiles: node3

eureka: 
  client: 
    serviceUrl:
      defaultZone: http://eureka3:8000/eureka/,http://eureka:8000/eureka/

在對應的機器上啓動euraka-test，即完成集羣創建，啓動命令如下：

nohup /opt/cloud/jdk/bin/java -Dspring.profiles.active=node1 -server -Xmx4g -Xms4g -Xss256k -XX:+UseG1GC -XX:+PrintGCDateStamps -Xloggc:/opt/cloud/gc.log -jar /opt/cloud/eureka-test.jar > /opt/cloud/stdout.log &
nohup /opt/cloud/jdk/bin/java -Dspring.profiles.active=node2 -server -Xmx4g -Xms4g -Xss256k -XX:+UseG1GC -XX:+PrintGCDateStamps -Xloggc:/opt/cloud/gc.log -jar /opt/cloud/eureka-test.jar > /opt/cloud/stdout.log &
nohup /opt/cloud/jdk/bin/java -Dspring.profiles.active=node3 -server -Xmx4g -Xms4g -Xss256k -XX:+UseG1GC -XX:+PrintGCDateStamps -Xloggc:/opt/cloud/gc.log -jar /opt/cloud/eureka-test.jar > /opt/cloud/stdout.log &

二、增加provider-test

pom很簡單：

<parent>
    <groupId>com.sohu.tv</groupId>
    <artifactId>spring-cloud-test</artifactId>
    <version>1.0-SNAPSHOT</version>
</parent>

<artifactId>provider-test</artifactId>
<packaging>jar</packaging>

<dependencies>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-eureka</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
</dependencies>

代碼主要是rest接口（hello10:返回10個字符，hello100：返回100個字符，hello1000：返回1000個字符）：

private String c10 = "abcvdfjiel";
private String c100 = "abcvdfjiel0938271648losdgshaiougoiewnavoienoidsa[yg[0e0u9g-rendsvsatg439098u6y480vb309ja0sv[nsdijfd";
private String c1000 = "abcvdfjiel0938271648losdgshaiougoiewnavoienoidsa[yg[0e0u9g-rendsvsatg439098u6y480vb309ja0sv[nsdijfdabcvdfjiel0938271648losdgshaiougoiewnavoienoidsa[yg[0e0u9g-rendsvsatg439098u6y480vb309ja0sv[nsdijfddabcvdfjiel0938271648losdgshaiougoiewnavoienoidsa[yg[0e0u9g-rendsvsatg439098u6y480vb309ja0sv[nsdijfdabcvdfjiel0938271648losdgshaiougoiewnavoienoidsa[yg[0e0u9g-rendsvsatg439098u6y480vb309ja0sv[nsdijfddabcvdfjiel0938271648losdgshaiougoiewnavoienoidsa[yg[0e0u9g-rendsvsatg439098u6y480vb309ja0sv[nsdijfdabcvdfjiel0938271648losdgshaiougoiewnavoienoidsa[yg[0e0u9g-rendsvsatg439098u6y480vb309ja0sv[nsdijfddabcvdfjiel0938271648losdgshaiougoiewnavoienoidsa[yg[0e0u9g-rendsvsatg439098u6y480vb309ja0sv[nsdijfdabcvdfjiel0938271648losdgshaiougoiewnavoienoidsa[yg[0e0u9g-rendsvsatg439098u6y480vb309ja0sv[nsdijfddabcvdfjiel0938271648losdgshaiougoiewnavoienoidsa[yg[0e0u9g-rendsvsatg439098u6y480vb309ja0sv[nsdijfdabcvdfjiel0938271648losdgshaiougoiewnavoienoidsa[yg[0e0u9g-rendsvsatg439098u6y480vb309ja0sv[nsdijfdddsds";

@RequestMapping("/hello10")
public String hello10() {
    return c10;
}

@RequestMapping("/hello100")
public String hello100() {
    return c100;
}

@RequestMapping("/hello1000")
public String hello1000() {
    return c1000;
}

還有一個主類：

@SpringBootApplication
@EnableDiscoveryClient
public class ProviderApplication {
    public static void main(String[] args) {
        SpringApplication.run(ProviderApplication.class, args);
    }
}

配置文件如下：

spring: 
  application: 
    name: spring-cloud-server

server: 
  port: 9003
  tomcat: 
    maxThreads: 500
    uriEncoding: utf-8

eureka:  
  instance: 
    preferIpAddress: true
    instanceId: ${spring.cloud.client.ipAddress}:${server.port}
  client: 
    serviceUrl: 
       defaultZone: http://eureka3:8000/eureka/,http://eureka:8000/eureka/,http://eureka2:8000/eureka/

啓動兩臺機器提供服務，啓動腳本如下：

nohup /data/cloud/jdk/bin/java -server -Xmx4g -Xms4g -Xss256k -XX:+UseG1GC -XX:+PrintGCDateStamps -Xloggc:/data/cloud/gc.log -jar /data/cloud/provider-test.jar > /data/cloud/stdout.log &

三、增加consumer-test實現

pom如下：

<parent>
    <groupId>com.sohu.tv</groupId>
    <artifactId>spring-cloud-test</artifactId>
    <version>1.0-SNAPSHOT</version>
</parent>

<artifactId>consumer-test</artifactId>
<packaging>jar</packaging>

<dependencies>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-eureka</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-feign</artifactId>
    </dependency>
</dependencies>

代碼如下：

1 啓動類：
@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients
public class ConsumerApplication {
    public static void main(String[] args) {
        SpringApplication.run(ConsumerApplication.class, args);
    }
}

2 feign 服務
@FeignClient(name = "spring-cloud-server"/**)
public interface ConsumerService {
    @RequestMapping("/hello10")
    public String hello10();
     
    @RequestMapping("/hello100")
    public String hello100();
     
    @RequestMapping("/hello1000")
    public String hello1000();
}

3 對外的rest接口
@RestController
public class ConsumerController {
    @Autowired
    ConsumerService consumerService;
     
    @RequestMapping("/hello10")
    public String hello10() {
        return consumerService.hello10();
    }
     
    @RequestMapping("/hello100")
    public String hello100() {
        return consumerService.hello100();
    }
     
    @RequestMapping("/hello1000")
    public String hello1000() {
        return consumerService.hello1000();
    }
}

配置文件如下：

spring: 
  application:
    name: spring-cloud-consumer

server:
  port: 9001
  tomcat: 
    maxThreads: 1000
    uriEncoding: utf-8

eureka:
  instance:
    preferIpAddress: true
    instanceId: ${spring.cloud.client.ipAddress}:${server.port}
  client:
    serviceUrl:
      defaultZone: http://eureka3:8000/eureka/,http://eureka:8000/eureka/,http://eureka2:8000/eureka/

feign:
  hystrix: 
    enabled: false     

spring-cloud-server: 
  ribbon: 
    MaxAutoRetries: 1
    ConnectTimeout: 2000
    ReadTimeout: 1000
    OkToRetryOnAllOperations: false
    EnableGZIPContentEncodingFilter: true

啓動腳本：

nohup /opt/cloud/jdk/bin/java -server -Xmx4g -Xms4g -Xss256k -XX:+UseG1GC -XX:+PrintGCDateStamps -Xloggc:/opt/cloud/gc.log -jar /opt/cloud/consumer-test.jar > /opt/cloud/stdout.log &

四、feign性能測試

爲了測試不同的http客戶端的表現，並未增加hystrix的支持，consumer的鏈接超時爲2秒，讀取超時爲1秒，另外，每次測試都經過了預熱，只測試小數據傳輸

爲consumer增加client依賴

<dependency>
    <groupId>io.github.openfeign</groupId>
    <artifactId>feign-httpclient</artifactId>
</dependency>
或
<dependency>
    <groupId>io.github.openfeign</groupId>
    <artifactId>feign-okhttp</artifactId>
</dependency>
或什麼都不依賴，採用jdk的URLConnection

進行性能壓測，併發3000，壓測10萬次，採用長鏈，分別壓測3個接口：

ab -k -n 100000 -c 3000 http://127.0.0.1:9001/hello10

ab -k -n 100000 -c 3000 http://127.0.0.1:9001/hello100

ab -k -n 100000 -c 3000 http://127.0.0.1:9001/hello1000

機器配置如下：

cpu核數主頻

consumer-test 16 2.40GHz

provider-test 16 2.27GHz

	cpu核數	主頻
consumer-test	16	2.40GHz
provider-test	16	2.27GHz

具體數據如下（併發3000，壓測10萬次表現如下(壓測3次以上，取最好表現)）：

client	10個字符	100個字符		1000個字符
	吞吐量	響應時間中位值	吞吐量	響應時間中位值	吞吐量	響應時間中位值
httpclient	3542	846ms	3526	850ms	3427	875ms
okhttp	14389	208ms	13782	217ms	13761	218ms
JDK URLConnection	13728	218ms	13577	220ms	13800	217ms

五、resttemplate性能測試

consumer採用resttemplate作爲測試，代碼比較簡單，如下：

1 默認實現 - 採用jdk的HttpURLConnection
@LoadBalanced
@Bean
public RestTemplate restTemplate() {
    return new RestTemplate(f);
}

2 採用okhttp3
@LoadBalanced
@Bean
public RestTemplate restTemplate() {
    OkHttp3ClientHttpRequestFactory f  =new OkHttp3ClientHttpRequestFactory();
    f.setConnectTimeout(2000);
    f.setReadTimeout(1000);
    f.setWriteTimeout(1000);
    return new RestTemplate(f);
}

3 採用httpclient 4.3
@LoadBalanced
@Bean
public RestTemplate restTemplate() {        
    HttpComponentsClientHttpRequestFactory f = new HttpComponentsClientHttpRequestFactory();
    f.setConnectTimeout(2000);
    f.setReadTimeout(1000);
    return new RestTemplate(f);
}

壓測表現如下：（併發3000，壓測10萬次表現如下(壓測3次以上，取最好表現)）：

client	10個字符	100個字符		1000個字符
	吞吐量	響應時間中位值	吞吐量	響應時間中位值	吞吐量	響應時間中位值
httpclient	6058	495ms	6051	495ms	6021	498ms
okhttp	16134	185ms	16194	185ms	15885	188ms
JDK URLConnection	16009	187ms	15695	191ms	15172	197ms

六、結論

從壓測數據表現來看，性能上resttemplate整體上更勝一籌（可能由於feign採用了動態代理和反射機制）。

在各個http客戶端默認配置下，okhttp3性能更好一些。

從代碼優雅角度來講，feign更簡潔，易懂。

測試結果依賴於測試的環境和數據，及依賴的軟硬件版本和性能，不代表所有情況！
