# Gatling-Dubbo 2.0
`【招聘】Java开发、测试开发等岗位，有意者请将简历投递至`
Gatling的非官方Dubbo压测插件，基于Gatling 2.3.1，插件已在Dubbo 2.6.5上测试，但理论上所有Dubbo版本都适用，`2.0插件采用普通API调用方式执行压测请求，如果你想使用泛化调用方式执行压测请求，请参考`[1.0插件](https://github.com/youzan/gatling-dubbo/tree/v1.0)`，推荐使用2.0插件，即采用普通API调用方式，因为 dubbo 官方推荐生产上使用该方式，所以以同样的方式压测得到的结果，更具有参考意义，且2.0插件无需 dubbo 框架做任何改造。`
> 区别于 Gatling-Dubbo 1.0 只支持 dubbo 压测，Gatling-Dubbo 2.0 不仅支持 dubbo 压测，还支持非 dubbo 的其他 java 调用压测，因为脚本中的 `f` 怎么写控制权在你手里，就像使用 Jmeter 压测 java 一样。
## 使用方法
### 打包Jar
> 按需修改配置:
- 默认为4核8G内存机器配置了200线程池，与dubbo线程池一致，你也可以根据自己的机器配置使用API调整线程池大小，下述
- 如果你使用其他Dubbo版本，请修改根目录下build.sbt中的libraryDependencies配置
> 如果你不需要修改配置，可以略过以下打包步骤，直接[下载Jar包（该 Jar 包无应用依赖）](https://github.com/youzan/gatling-dubbo/releases)
项目依赖sbt，请安装sbt 1.2.1，详见[官方文档](https://www.scala-sbt.org/1.x/docs/Setup.html)，执行
```bash
$ git clone https://github.com/youzan/gatling-dubbo.git
$ cd gatling-dubbo
$ sbt assembly
```
### 将上述jar包拷贝到/your-path-to/gatling-charts-highcharts-bundle-2.3.1/lib目录
```bash
$ cp /your-path-to/gatling-dubbo/target/scala-2.12/gatling-dubbo-assembly-1.0.jar /your-path-to/gatling-charts-highcharts-bundle-2.3.1/lib
```
### 依赖
由于插件采用普通API调用方式执行压测请求，所以需要引入服务特定的 API 包，为了演示方便，这里直接将依赖写在了项目根目录下的 build.sbt 中：
```sbtshell
name := "gatling-dubbo"
version := "1.0"
scalaVersion := "2.12.6"
libraryDependencies ++= Seq(
"io.gatling" % "gatling-core" % "2.3.1" % "provided",
"com.alibaba" % "dubbo" % "2.6.5",
"com.youzan.xxx" % "xxx-api" % "1.xxx-RELEASE" exclude("ch.qos.logback", "logback-classic") //应用 API 包
)
assemblyOption in assembly := (assemblyOption in assembly).value.copy(includeScala = false)
```
### 创建Simulation和相应的json数据文件
参考gatling-dubbo/src/test/scala目录下的DubboTest.scala和data.json
`DubboTest.scala`具体说明请参考示例
> check 说明
目前 check 支持两种，jsonPath 和 custom，如果 dubbo 返回值可以转化为 json（如 PlainResult、Map 等），则推荐使用 jsonPath 校验结果，如果 dubbo 返回值是 String 等类型，则推荐使用 custom 校验结果，即自定义校验逻辑，custom 的示例如下：
```scala
.check(custom((response: String) => {
print(response)
response == "expected response"
}, "option error message"))
```
> 示例中展示的是单接口的例子，如果你想探测应用单机的真实水位，可以结合使用 gatling 的 randomSwitch 混合多接口且按生产环境真实的接口比例同时进行压测。
`data.json`
```json
[
{
"kdtId": 160,
"page": 1
},
{
"kdtId": 160,
"page": 2
},
{
"kdtId": 160,
"page": 3
}
]
```
数据采用 json 数组保存，其中每一个 json 对象都是一次压测请求需要的完整参数，且为了方便通过 session 设置动态参数，数据结构采用一维结构，风格同 Jmeter。
### 执行Dubbo压测
```bash
$ bin/gatling.sh
GATLING_HOME is set to /your-path-to/gatling-charts-highcharts-bundle-2.3.1
Choose a simulation number:
[0] dubbo.DubboTest
0
Select simulation id (default is 'dubbotest'). Accepted characters are a-z, A-Z, 0-9, - and _
Select run description (optional)
