搭建eclipse版的ssm+maven+tk.mybatis+redis及mybatis+spring多数据源配置集成的demo
生活随笔
收集整理的這篇文章主要介紹了
搭建eclipse版的ssm+maven+tk.mybatis+redis及mybatis+spring多数据源配置集成的demo
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
前言：我這里搭建好eclipse版的ssm+maven+tk.mybatis+redis及mybatis+spring多數據源配置集成的demo。新手快速上手直接看demo。
最后處提供完整高質量demo！！！
?
準備工作
1、redis下載及配置(demo中有)
(1)下載window或linux版(那本地需要裝虛擬機)redis
(2)redis.conf修改(linux版也一樣)
? 注釋：# bind 127.0.0.1
? 密碼：requirepass 123(自定義密碼)
(3)運行，雙擊redis-startup.bat運行
redis-startup.bat是我自己寫的腳本，內容很簡單
redis-server.exe redis.conf2、Eclipse配置mybatis-generator插件
參考：https://blog.csdn.net/u012825737/article/details/79117540
配置好后，右鍵generatorConfiguration.xml即可生成文件
先來一波完整的配置
3、框架搭建的配置文件

ok，大體搭建成。。
測試
http://localhost:8080/more-datasource/book/list
http://localhost:8080/more-datasource/book/add
http://localhost:8080/more-datasource/book/add2
效果
redis使用客戶端工具查看
所有切換數據源配置在DataSourceInterceptor.java這個文件里動態配置！！！
整理不少時間。。。
下載整合demo
忘記把客戶端工具弄進來了。。
redis客戶端工具
