我有一个由maven驱动的spring-boot项目我想使用Gatling运行负载测试。 此时，我可以运行我的模拟键入以下命令：
mvn gatling:execute
它可以正常工作但我必须手动启动我的springboot应用程序，否则它将无效。
这是我的模拟课程：
package main.aperture.gatling
import aperture.config.SpringBootApertureTestingConfiguration
import io.gatling.core.Predef._
import io.gatling.core.structure.ScenarioBuilder
import io.gatling.http.Predef._
import io.gatling.http.protocol.HttpProtocolBuilder
import org.springframework.boot.SpringApplication
import org.springframework.context.ConfigurableApplicationContext
import scala.concurrent.duration._
import scala.language.postfixOps
/**
* This class is meant to load test main get routes of this app
* The app has to be launched first (Manually, unfortunately)
*/
class MainSimulation extends Simulation {
val baseUrl: String = "localhost"
val port: String = System.getProperty("server.port", "8080")
val httpConf: HttpProtocolBuilder = http
.baseURL(s"http://$baseUrl:$port") // Here is the root for all relative URLs
val scenario_main_get: ScenarioBuilder = scenario("Testing main get routes")
.exec(http("Request on main route")
.get("/"))
.pause(100 milliseconds)
.exec(http("Request on rooms main route")
.get("/api/rooms"))
.pause(100 milliseconds)
.exec(http("Request on subjects main route")
.get("/api/subjects"))
.pause(100 milliseconds)
.exec(http("Request on supervisors main route")
.get("/api/supervisors"))
setUp(scenario_main_get.inject(rampUsers(1000) over (5 seconds)).protocols(httpConf))
}
这是我的 pom.xml （我删除了不相关的元素）：

我希望能够在使用gatling运行负载测试之前自动运行spring-boot应用程序。 有些人建议在我的模拟开始时添加以下代码：
val app: ConfigurableApplicationContext = SpringApplication.run(classOf[SpringBootApertureTestingConfiguration])
Runtime.getRuntime.addShutdownHook(new Thread() {
override def run(): Unit = app.stop()
})
但是当我这样做时，执行它时会出现以下错误：

也许我忘记了某些内容或者我的配置中缺少某些内容，但我在文档中找不到任何有关我的具体问题的帮助。有人说它是一个spring-boot dev工具bug。
有谁知道如何纠正这个问题？
即使我的模拟在spring-boot项目中的包中，也不意味着它与项目相关联。因此，想要直接在代码中启动它可能无关紧要。但是，有没有人找到解决方法？
提前感谢您的帮助。
答案 0 :(得分：2)
我正在寻找类似的东西，发现它可以工作：
mvn spring-boot:start gatling:test spring-boot:stop
在before钩中启动应用程序也可以。
这样的好处是您可以将应用程序配置（例如url）设置为外部服务，然后可以对其进行模拟。使用WireMock：
在Simulation类中，添加：
before {
val app = SpringApplication.run(classOf[Application])
app.registerShutdownHook()
}
答案 1 :(得分：1)
您是否考虑过在简单的shell脚本中包装它并从spring boot maven插件启动应用程序？
http://docs.spring.io/spring-boot/docs/1.5.3.RELEASE/maven-plugin/run-mojo.html。
否则你应该能够将spring boot插件挂钩到maven生命周期中，然后在没有shell脚本的情况下运行。
答案 2 :(得分：0)
Patrick的回答提供了足够的元素来考虑使用简单的shell脚本。如果你遇到过这样的问题，这里是我写的代码：
#!/usr/bin/env bash
# ########### FUNCTIONS
trim(){
[[ "$1" =~ ^[[:space:]]*(.*[^[:space:]])[[:space:]]*$ ]]
printf "%s" "${BASH_REMATCH[1]}"
}
# ########### MAIN PROGRAM
# ------ First, launch the spring-boot app in background
mvn spring-boot:run &
# ------ Then, wait for it to be correctly initialized
portExtracted=`awk '/server/,/port/' ./src/main/resources/application.yml | cut -d ":" -f 2`
portToListenTo=`trim ${portExtracted}`
i=0
maxCounter=100
while [[ ! $(lsof -i :"$portToListenTo") ]] && [ ${i} -lt ${maxCounter} ]
do
echo 'Waiting for spring-boot app to be up and running.'
sleep 2
i=$[$i+1]
done
mvn gatling:execute
您必须根据需要调整它：更改配置文件的路径和awk命令以动态提取应用程序的端口。
任何有关增强剧本的建议都表示赞赏。
编辑：我还用pom中的以下内容替换了spring-boot maven插件描述：
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<mainClass>aperture.config.SpringBootApertureTestingConfiguration</mainClass>
</configuration>
<executions>
<execution>
<id>pre-integration-test</id>
<goals>
<goal>start</goal>
</goals>
</execution>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
<execution>
<id>post-integration-test</id>
<goals>
<goal>stop</goal>
</goals>
</execution>
</executions>
</plugin>
这样，app就会在运行gatling测试之前启动。为此，只需运行mvn verify命令即可。如果您不跳过测试，它也适用于mvn clean install。
希望这有帮助！
答案 3 :(得分：0)
如上所述，简化的脚本可能是：
#!/usr/bin/env bash
set -e -x
mvn spring-boot:start
mvn gatling:execute
mvn spring-boot:stop
