Spring + Spring MVC + Mybatis 高性能web构建实例教程详解

　　用最合适的技术去实现，并不断追求最佳实践。这就是架构之道。

　　希望这篇文章能给你们带来一些帮助，同时希望你们可以为这个项目贡献你的想法。

　　看我们的项目结构：

　　是一个典型的Maven 项目 ：

　　src/main/Java：存放java源文件

　　src/main/resources：存放程序资源、配置文件

　　src/test/java：存放测试代码文件

　　src/main/webapp：web根目录

　　pom.xml ： maven项目配置文件，管理依赖，编译，打包

　　主要的后端架构：spring + Spring MVC + Mybatis + Apache Shiro

　　前端界面主要使用Metronic 模板,

　　先看我们搭建完成，跑起来的效果，这样你才有兴趣看下去：

　　你可以 在github 上 checkout quick4j项目 查看 ，并跟下面步骤 来搭建：

　　强烈建议你，checkout https://github.com/Eliteams/quick4j ，在本地跑起来，再试着自己搭建框架

　　1、首先创建 maven 项目 ，用 idea 、eclipse 或 mvn 命令行都行

　　2、配置 pom.xml ，添加框架依赖

3、配置web.xml

web.xml是一个项目的核心，看看它的一些配置：

配置 ContextLoaderListener 监听器

配置Spring字符编码过滤器

配置shiro 安全过滤器

配置Spring MVC 核心控制器 DispatcherServlet

配置一些页面

spring 和 apache shiro 是由一个 ContextLoaderListener 监听器 加载的配置文件，并初始化
