說明:
本文章介紹如何使用jmeter測(cè)試dubbo接口,涉及如下兩種方式
1.使用官方dubbo版本包測(cè)試dubbo接口
2.通過自己編寫java請(qǐng)求插件,實(shí)現(xiàn)dubbo調(diào)用
選擇方式1或方式2并沒有什么區(qū)別,取決于部分自研公司對(duì)dubbo進(jìn)行了封裝,導(dǎo)致官方提供的dubbo包并不適用于方式1,則可以通過方式2去調(diào)用
方式1:使用官方dubbo版本包調(diào)用dubbo接口
登陸以下地址下載jmeter的dubbo插件包
https://github.com/ningyu1/jmeter-plugins-dubbo/releases
解壓tar將獲取到的jar包放入${JMETER_HOME}\lib\ext路徑下(這里獲取到的jar包為jmeter-plugins-dubbo-2.7.1-jar-with-dependencies)，重啟jmeter應(yīng)用(這里重啟完應(yīng)用會(huì)添加取樣器會(huì)多出一個(gè)dubbo sample)
1.添加線程組
右鍵添加,選擇線程->線程組
2.添加dubbo sample
2.光標(biāo)對(duì)準(zhǔn)線程組右鍵添加->取樣器->dubbo sample
3.配置參數(shù)說明如下
此處需要關(guān)注,當(dāng)方法接收的是一個(gè)String,或者List等類型的參數(shù),可參照截圖配置
那么當(dāng)方法接收的參數(shù)是一個(gè)對(duì)象時(shí),需要獲取對(duì)接接口的api jar包并關(guān)聯(lián)到當(dāng)前測(cè)試計(jì)劃
選中測(cè)試計(jì)劃,點(diǎn)擊下方瀏覽按鈕,選擇對(duì)應(yīng)的jar包
傳參的具體方式可參照如下
4.點(diǎn)擊發(fā)送按鈕,查看結(jié)果
接口1返回:
接口2返回
方式2:編寫java請(qǐng)求方式請(qǐng)求dubbo接口
看了下網(wǎng)上的大多請(qǐng)求都是單接口請(qǐng)求dubbo,這樣就會(huì)導(dǎo)致,每次有新的接口的時(shí)候都得去更新新的請(qǐng)求,這里提供一個(gè)一勞永逸的方法,通過泛化調(diào)用,實(shí)現(xiàn)一個(gè)jar請(qǐng)求可適配所有接口,一般看到這個(gè)文章的可能大多都是測(cè)試的同學(xué),對(duì)于當(dāng)前方法需要對(duì)java有一定的基礎(chǔ),所以這個(gè)時(shí)候就體驗(yàn)到學(xué)習(xí)的重要性了,下面開始操作吧
1.創(chuàng)建maven項(xiàng)目
file->new->project,選擇maven
輸入組織->坐標(biāo)后點(diǎn)擊next
按需配置名稱路徑后點(diǎn)擊finsh
pom.xml配置如下

打包操作
左側(cè)窗口為生成的jar包和lib目錄
這里要說明下,網(wǎng)上提供了一種方式,通過修改安裝目錄bin下jmeter.properties文件關(guān)聯(lián)lib下的依賴
文件中增加如下(通過嘗試,這么做會(huì)導(dǎo)致jmeter啟動(dòng)由于jar包加載順序的問題,ui部分控件不可用)
search_paths=D:/Software/apache-jmeter-5.0/lib-dependency
這里我使用的是另一種更為簡(jiǎn)便的方式
將原安裝目錄lib下ext修改為extbak
新建ext,并將工程lib下的jar包和dobbo-jmeter-interface-1.0-SNAPSHOT.jar放入之
由于可能會(huì)用到隨機(jī)函數(shù),從extbak獲取ApacheJMeter_functions.jar,也放入到新建的ext目錄下
重啟jmeter,稍等片刻
添加java請(qǐng)求
添加結(jié)果樹
點(diǎn)擊運(yùn)行后,結(jié)果樹信息如下
后續(xù)可自行配置斷言和隨機(jī)參數(shù)等
