推薦一個(gè) Java 接口快速開發(fā)框架
干掉Random：這個(gè)類已經(jīng)成為獲取隨機(jī)數(shù)的王者
Docker + Intellij IDEA，提升 10 倍生產(chǎn)力！
笑出腹肌的注釋，都是被代碼耽誤的詩(shī)人！
同事亂用 Redis 卡爆，我真是醉了...
RedisJson 橫空出世，性能碾壓ES和Mongo！

一怒之下搞我大 JAVA，驗(yàn)證可行與場(chǎng)景體遐想。廢話不多說(shuō)，先上硬貨。

依賴導(dǎo)入

從博文上看是 exifread 模塊，找我大 java 的對(duì)應(yīng)的 jar，發(fā)現(xiàn) metadata-extractor，而且官方還在持續(xù)更新，最近的 jar 是今年的。

這個(gè)元數(shù)據(jù)提取 jar 非常強(qiáng)大，還支持視頻信息的提取，看看官方介紹：

看到?jīng)]，第一個(gè)示例，就寫的支持我大 JAVA，讓我猶如雞血沖頂，在支持同事聯(lián)調(diào)事件工單的同時(shí)，大肝這塊。

準(zhǔn)備工作

1、室外空曠地點(diǎn)打開 GPS

2、百度地圖、北斗伴驗(yàn)證已連接到 GPS 定位

3、設(shè)置手機(jī)帶的照相機(jī)開啟位置信息

4、拍照一張順便查看照片詳情

這里一定要確定拍的照片的詳情時(shí)有經(jīng)緯度信息的，如果沒(méi)有，你針對(duì)你的手機(jī)在 CSDN 里搜索下怎么設(shè)置。這里順便提下，CSDN 的瀏覽器插件真香。簡(jiǎn)直就是我們技術(shù)人事的福音，再以不用擔(dān)心某某度的廣告之類導(dǎo)致找東西費(fèi)勁了，而且它很包容，還時(shí)可以選擇自己喜歡的搜索引擎的。

這里先演示這個(gè)元數(shù)據(jù)提取 jar 能提取到的信息，順便把取到的經(jīng)緯度通過(guò)百度轉(zhuǎn)地址。

因?yàn)槭?demo，沒(méi)有業(yè)務(wù)，我這里就直接在測(cè)試類里干了。沒(méi)有什么業(yè)務(wù)，不涉及什么機(jī)密，可以上全碼。
