测试用到的代码：

[springboot-druid][]

### 0.java编译可执行程序,manen打包 ###

> c:\\jdk\\demoapp> javac HelloWorld.java  
> c:\\jdk\\demoapp> java HelloWorld  
> 命令行编译运行Java程序时，加载指定目录中的Jar包  
> 编译：javac -Djava.ext.dirs=./lib Test.java 或 javac -Djava.ext.dirs=D:/javacode/lib  
> 运行：java -Djava.ext.dirs=./lib Test

maven打包可以命令行也可以在编译器如idea中。

命令行：`mvn -Dmaven.test.skip=true clean install`

### 1.接口测试工具（curl;postman） ###

1)curl (curl -h 查询参数说明)

get请求:

curl http://192.168.3.2:8090/user?userName=admin\&passWord=1213
    //带多个参数也可也：
    curl  "http://192.168.3.2:8090/user?userName=admin&passWord=1213"
    curl  -s "http://192.168.3.2:8090/user?userName=admin&passWord=1213"
    //多个cookie使用分号分隔
    curl http://localhost:8090/test --cookie "userName=root;passWord=123456"
    
    //-u 带上代理用户信息，-i 参数来返回请求头和响应信息
    curl -i -u guest:guest http://localhost:15672/api/vhosts

post:

1)普通参数

curl -X POST -d 'userName=admin23&passWord=123456' http://192.168.3.2:8090/user/add2

2)参数为json

curl  -H  "content-type:application/json"  -XPOST -d  '{"userName":"admin6","passWord":"123456"}' http://192.168.3.2:8090/user

put:

1)普通参数

curl -X PUT -d 'id=11&userName=admin23_update&passWord=123456' http://192.168.3.2:8090/user/update2

2)参数为json

curl  -H "content-type:application/json"  -XPUT -d'{"id":11,"userName":"admin23_update2","passWord":"123456"}'  http://192.168.3.2:8090/user

delete:

1)普通参数

curl -v -X DELETE http://192.168.3.2:8090/user?id=9

2)参数为json

curl -i -u guest:guest -H "content-type:application/json"  -X DELETE -d'{"type":"direct","durable":true}' 
    http://localhost:15672/api/exchanges/%2f/my-new-exchange2

2)postman使用和idea自带的Http client 工具类似:

get请求:

### 2.压力测试工具 ###

#### 1)ab使用 ####

命令：

ab -n 100 -c 10 http://localhost:8090/user?userName=admin&passWord=123456
    //需要登录的接口，登录后找到cookie
    ab -n 100 -H “Cookie: Key1=Value1; Key2=Value2” http://localhost:8090/user?userName=admin&passWord=123456

输出:

#### 2)apache-jmeter使用 ####

1)点击jmeter.bat，打开界面
