redis-mongo项目介绍

摘要：项目主要是在框架下对双数据源进行配置和操作的实例，关于框架搭建这里就不予展示与介绍了，想了解的请参考之前的项目介绍项目代码获取功能分类增删改查双数据源切换对类型和类型进行缓存插入与读取项目结构代码双数据源配置相关类数据库交互层实体对象层相

项目主要是在spring、springmvc、mybatis框架下对mysql、mysql双数据源、redis、mongo进行配置和操作的实例，关于框架搭建这里就不予展示与介绍了，想了解的请参考之前的shiro项目介绍
项目代码获取：https://github.com/pysasuke/r...

mysql增删改查

mysql双数据源切换

redis对String类型和Object类型进行缓存

mongo插入与读取

core:双数据源配置相关类

dao:数据库交互层

entity:实体对象层

util:redis相关工具类

mapping:mybatis与实体映射文件存放包

application.xml:spring配置文件入口，加载spring-config.xml

spring-mvc.xml:springmvc配置相关文件

spring-config.xml:加载其他集成的配置文件

spring-mybatis.xml：mybatis相关配置文件

spring-mongo.xml：mongo相关配置文件

spring-redis.xml：redis相关配置文件

db.properties：数据库相关参数配置

log4j.properties：日志相关参数配置

redis.properties:redis相关参数配置

web.xml
