使用纯Java配置SSM框架实现基本的增删改查（不使用spring XML）

Posted 2021-02-05 hanzx

本文不使用spring XML，而是采用Java配置SSM框架的形式实现了基本的增删改查。 本文中的源码继承自https://www.cnblogs.com/hanzx/p/10016468.html中的程序，删除掉了webapp文件夹，里面的模板全部转移到resources下，其余文件均已删除。 核心框架已升级。spring系列已升级使用5.0.1，mybatis使用3.4.5，mybatis-spring使用1.3.1。

前言

本文不使用spring XML，而是采用Java配置SSM框架的形式实现了基本的增删改查。

本文中的源码继承自https://www.cnblogs.com/hanzx/p/10016468.html中的程序，删除掉了webapp文件夹，里面的模板全部转移到resources下，其余文件均已删除。

核心框架已升级。spring系列已升级使用5.0.1，mybatis使用3.4.5，mybatis-spring使用1.3.1。

 

名词解释

SSM框架：springMVC、spring、mybatis

thymeleaf：一个与Velocity、FreeMarker类似的模板引擎

jquery：一个快速、简洁的javascript框架
