play framework 2.x 是使用scala與java開(kāi)發(fā)的一款框架、不能說(shuō)是一個(gè)框架應(yīng)該說(shuō)是一種解決方案。
play framework 優(yōu)點(diǎn)有如下幾個(gè)：
- 開(kāi)發(fā)效率高、scala的特點(diǎn)函數(shù)式編程。
- 無(wú)狀態(tài)、可擴(kuò)展性極好。
- 熱部署、修改源碼直接動(dòng)態(tài)編譯、無(wú)需重啟服務(wù)。
- 優(yōu)秀的RESTFul框架。
- Play的生態(tài)圈在不斷擴(kuò)開(kāi)。
使用介紹
- jdk1.8環(huán)境安裝 (忽略)
- SBT安裝
- 模板框架使用
SBT安裝
使用版本為當(dāng)前文章時(shí)間點(diǎn)的最新版本1.2.8
Homebrew mac系統(tǒng)
brew install sbt@1
所有平臺(tái)壓縮包 sbt-1.2.8.zip
配置sbt的環(huán)境、與Java環(huán)境配置一樣
成功安裝如下
sbt -v
[process_args] java_version = '8'
# Executing command line:

運(yùn)行項(xiàng)目（首次運(yùn)行項(xiàng)目會(huì)下載包、這時(shí)間可以去喝一杯咖啡）
cd test
sbt run
成功結(jié)尾顯示如下

其它
訪問(wèn)不存在的接口則顯示如下
Intellij-idea debug調(diào)試如下
- debug方式運(yùn)行
sbt run -jvm-debug 9999
- 創(chuàng)建遠(yuǎn)程連接
- 直接對(duì)代碼debug即可
