性能工具之Ngrinder源码部署

转载：https://cloud.tencent.com/developer/article/1526398

背景

为了更好了解nGrinder怎么工作或者为下次二次开发便开启使用源码部署。

下载源码：

https://github.com/naver/ngrinder/releases

也可以直接通过：https://github.com/naver/ngrinder.git这种方式下部署

本次使用下载zip进行安装：

点击目录再点击：

等待执行成功便把如下安装到本地创库：

打开idea：

点击文件导入：

点击Open as Project:

打开新窗口：

等待maven加载相应的jar。

修改代码

具体代码如下：

package org.ngrinder.perftest.service;
import org.ngrinder.infra.config.Config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.EnableAspectJAutoProxy;
import org.springframework.context.annotation.Profile;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.transaction.annotation.EnableTransactionManagement;
/**
 * Dynamic creation of {@link PerfTestService} depending on the cluster enable or disable.
 *
 * @author JunHo Yoon
 * @since 3.1
 */
@Configuration
@Profile("production")
@EnableScheduling
@EnableTransactionManagement
@EnableAspectJAutoProxy
public class PerfTestServiceConfig implements ApplicationContextAware {
   @Autowired
   private Config config;
   private ApplicationContext applicationContext;
   /**
    * Create PerTest service depending on cluster mode.
    *
    * @return {@link PerfTestService}
    */
   @Bean(name = "perfTestService")
   public PerfTestService perfTestService() {
      if (config.isClustered()) {
         return applicationContext.getAutowireCapableBeanFactory().createBean(ClusteredPerfTestService.class);
      } else {
         return applicationContext.getAutowireCapableBeanFactory().createBean(PerfTestService.class);
      }
//    return applicationContext.getAutowireCapableBeanFactory().createBean(
//          config.isClustered() ? ClusteredPerfTestService.class : PerfTestService.class);
   }
   @Override
   public void setApplicationContext(ApplicationContext applicationContext) {
      this.applicationContext = applicationContext;
   }
}

再次配置tomcat

选择tomcat所在目录：

选择：

添加运行war:

选择时时更新运行:

注意最好是这样：

-Xms1024m -Xmx1024m -XX:MaxPermSize=200m防止内存出现异常显现

点击确定：

启动：

打开浏览器验证是否成功:

http://localhost:8081/ngrinder/login

登录成功:

使用源码调试简单脚本

在script-sample工程下的pom.xml文件种增加：

代码如下

<!-- https://mvnrepository.com/artifact/junit/junit -->
<dependency>
   <groupId>junit</groupId>
   <artifactId>junit</artifactId>
   <version>4.12</version>
   <scope>test</scope>
</dependency>

再次在idea中全局搜索：

groovy-all

查看版本号，统一修改为：

<version>2.4.16</version>

模仿编写脚本

通过平台生成脚本：

点击：
