为Gatling负载测试构建可执行JAR

我是Gatling(2.1.2)的新手,想要做一个小型原型项目给同事们展示.

根据快速入门页面,有几种方法可以用Gatling运行模拟:

  1. 将Gatling包解压缩到一个文件夹中,然后将我的模拟文件放到user-files/simulations文件夹中.bin/gatling.sh将编译并运行模拟文件.
  2. 使用gatling-maven-pluginmaven插件执行模拟.
  3. 用gatling-highcharts-maven-archetype,创建一个项目,并运行Engine类.

我发现了那些问题

对于1,很难为模拟类添加依赖项.我必须弄清楚需要什么罐子并将它们放到lib文件夹中.

对于2,它需要安装maven.

对于3,它只从IDE运行

我只想要一个简单的可执行JAR文件,其中所有依赖项捆绑在一起(我的模拟,加特林和第三方),并从任何机器(如EC2实例)运行它.

有没有办法实现这个目标？

更新1:

我尝试了方法3,但将所有项目文件从test文件夹移动到main,并用于maven-assembly-plugin构建具有依赖项的jar.当我尝试运行该文件时,出现以下错误:

我想这与Gatling配置有关,但不知道出了什么问题.

JavaFX项目的有效JAR签名

我一直在使用各种配方来使用Maven POM 为JavaFX项目生成可运行的JAR文件.这些Stackoverflow问题中的每一个都描述了同样的问题.令人沮丧的是,针对同一目标似乎有几种不同的解决方案.

问题:

java.lang.SecurityException:Manifest主要属性的签名文件摘要无效

在命令行上执行JAR文件时出错.虽然Netbeans可以愉快地运行程序并调试程序.

诊断

有关于此的几个Stackoverflow和论坛问题(下面最有用的).尽管已知问题,但我还没有找到一个与JavaFX一起使用的明确解决方案.这些答案中描述的过程不是用于捆绑JavaFX JAR 的JavaFxPackager工具:

通常的方法:这个问题的帖子流行答案(撰写本文时为255票):在我们的项目中使用非 -JavaFX模块:

但是,当我们将相同的插件放在构建JavaFX JAR文件的POM中时,我们仍然得到:" 无效的签名文件摘要 ..."错误.具体来说,我<artifactId>maven-shade-plugin</artifactId>在JavaFxPackager exec规则之前和之后放置了第一个.结果是

  • Maven给出:" Manifest主要属性的无效签名文件摘要 ......"错误

RESTEasy:找不到内容类型application/json类型的writer

我有一个宁静的服务(post)消耗(application/json)并生成(application/json).此服务的单个参数是带注释的java对象.

我正在使用org.jboss.resteasy.client.ClientRequest将请求发送到服务.但是,我在客户端获得此异常并且异常:

从 maven 使用 JavaFX11 构建可执行 JAR

我正在使用来自http://nitschinger.at/Using-JMH-for-Java-Microbenchmarking/的简单入门案例:

public class MyBenchmark {

    @Benchmark
    public void testMethod() {
        // This is a demo/sample template for building your JMH benchmarks. Edit as needed.
        // Put your benchmark code here.
    }

    public static void main(String... args) throws Exception {
          Options opts = new OptionsBuilder()
              .include(".*")
              .warmupIterations(10)
              .measurementIterations(10)
//            .jvmArgs("-server")
              .forks(1)
//            .outputFormat(OutputFormatType.TextReport)
              .build();

          new Runner(opts).run();
        }    
}

我按照JMH文档中的规定生成了POM,并添加了JMH中指定的exec-maven-plugin 无法找到资源:/ META-INF/BenchmarkList:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

JMH没有主要的清单属性

我刚刚使用这个命令创建了一个Maven项目:

$ mvn archetype:generate \
      -DinteractiveMode=false \
      -DarchetypeGroupId=org.openjdk.jmh \
      -DarchetypeArtifactId=jmh-java-benchmark-archetype \
      -DgroupId=org.sample \
      -DartifactId=test \
      -Dversion=1.0

然后我做了一个mvn clean install跟着java -jar test-1.0.jar

该程序给了我这个消息

no main manifest attribute, in target/test-1.0.jar

我查看了清单,没有Main-Class属性.

这应该产生它:
