# 环境准备 #

## 项目准备 ##

### 接口编写 ###

提供一个压测接口 `http://127.0.0.1:8080/test?name=zhangsan`

@SpringBootApplication
    @RestController
    public class MavenDockerDemoApplication {
        public static void main(String[] args) {
            SpringApplication.run(MavenDockerDemoApplication.class, args);
        }
        @GetMapping("/test")
        public String test(String name) {
            name = "名称为:"+name;
            System.out.println(name);
            return name;
        }
    }

## 环境准备 ##

jdk:1.8

系统：centos 7

配置：2核4cpu

## 工具准备 ##

apache-jmeter-5.1.1

# 脚本编写 #

## 启动jmeter ##

运行apache-jmeter-5.1.1/bin/jmeter.bat

## 新建测试用例 ##

### 新建线程组 ###

填写参数

Name：线程组的名称

Number of Thread（User）：线程数

Ramp-Up Period（in seconds）：决定多长时间启动所有线程

Loop count：循环次数

我这里配置：

Name:50线程并发 
    Number of Thread（User）：50
    Ramp-Up Period（in seconds）：10
    Loop count：10000

这个配置的请求次数为500000

### 添加http request ###

点击线程组-add-Sampler-HTTP request 填写参数 Name：请求名称

Protocol：协议

Server Name or IP：域名或者ip地址

Prot Number：端口号

Method：请求方式

Path：请求的url

Content encoding：请求编码

parameter:接口参数

我这里配置：

Name:testrequest
    Protocol：http
    Server Name or IP：127.0.0.1
    Prot Number：8080
    Method：get
    Path：/test
    Content encoding:utf-8
    parameter：name=zhangsan

## 添加HTTP herder manager ##

Content-Type = application/json

## jmx配置文件 ##

# 性能压测 #

在服务器上部署，执行jmx文件 jtl保存压测结果 `../bin/jmeter-n-t test.jmx-l result/test.jtl`

# jmx飞行器监控 #

用jdk提供的jmc进行监控，监控项目提供的jmx端口

![format_png 1][]

添加飞行记录，记录一分钟内压测的数据

![format_png 2][]

然后根据各自提供的指标进行分析

![format_png 3][]

最后把测试结果test.jtl用jmeter打开分析

![format_png 4][]
