基于Hutool的圖片驗(yàn)證碼功能模塊實(shí)現(xiàn)
簡(jiǎn)介
Hutool是一個(gè)小而全的Java工具類庫(kù)，通過(guò)靜態(tài)方法封裝，降低相關(guān)API的學(xué)習(xí)成本，提高工作效率，使Java擁有函數(shù)式語(yǔ)言般的優(yōu)雅，讓Java語(yǔ)言也可以“甜甜的”。
Hutool中的工具方法來(lái)自每個(gè)用戶的精雕細(xì)琢，它涵蓋了Java開(kāi)發(fā)底層代碼中的方方面面，它既是大型項(xiàng)目開(kāi)發(fā)中解決小問(wèn)題的利器，也是小型項(xiàng)目中的效率擔(dān)當(dāng)；
Hutool是項(xiàng)目中“util”包友好的替代，它節(jié)省了開(kāi)發(fā)人員對(duì)項(xiàng)目中公用類和公用工具方法的封裝時(shí)間，使開(kāi)發(fā)專注于業(yè)務(wù)，同時(shí)可以最大限度的避免封裝不完善帶來(lái)的bug。
Hutool名稱的由來(lái)
Hutool = Hu + tool，是原公司項(xiàng)目底層代碼剝離后的開(kāi)源庫(kù)，“Hu”是公司名稱的表示，tool表示工具。Hutool諧音“糊涂”，一方面簡(jiǎn)潔易懂，一方面寓意“難得糊涂”。
基于Hutool的圖片驗(yàn)證碼功能模塊實(shí)現(xiàn)
1.背景
為了提高系統(tǒng)的安全性，防止接口被暴力刷新，驗(yàn)證碼是個(gè)好的手段，圖片驗(yàn)證碼沒(méi)有短信驗(yàn)證碼的費(fèi)用，其是個(gè)人開(kāi)發(fā)者學(xué)習(xí)的重點(diǎn)。
2.方案設(shè)計(jì)
2.1 方案步驟
- 引入Hutool工具集
- 安裝Redis
- 接入Reids配置
2.2 Hutool工具類引入
<dependency>
<groupId>cn.hutool</groupId>
<artifactId>hutool-all</artifactId>
<version>5.8.8</version>
</dependency>
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>3.7.0</version>
</dependency>2.3 安裝Redis
默認(rèn)端口：6379 - 下載連接 https://github.com/tporadowski/redis/releases - 解壓 - 雙擊redis-server.exe啟動(dòng)服務(wù)端 - 雙擊redis-cli.exe啟動(dòng)客戶端連接服務(wù)端
2.4 接入Reids配置
在ClassPath（或者src/main/resources）的config目錄下下新建redis.setting
