前言

Maven+Spring+SpringMVC+Hibernate+Mysql的简单整合（入门级），实现数据库的增删查改。Maven管理项目，统一开发规范和工具、统一管理Jar包。Spring轻量级的Java开发框架、控制反转IOC和依赖注入DI来管理对象依赖关系.、面向切面编程AOP来管理事物等。SpringMVC轻量级Web框架，使用MVC架构思想对web层进行解耦，简化开发。Mybatis半自动ORM（对象关系映射）框架,是支持定制化 SQL、存储过程以及高级映射的优秀的持久层框架。Mysql关系型数据库。javascript

前端使用Bootstrap 框架,用于开发响应式布局，界面风格简洁美观。css

效果图

开发环境

JDK1.7
Tomcat7
Spring 4.3.7
SpringMVC 4.3.7
Maven 3.3
Mybatis3.2.6

每一个基于 MyBatis 的应用都是以一个 SqlSessionFactory 的实例为中心的。SqlSessionFactory有一些属性，包括数据源、映射文件、mybatis其它相关配置。从SqlSessionFactory中获取sqlSession,SqlSession 彻底包含了面向数据库执行 SQL 命令所需的全部方法。把SqlSession注入dao层使用。前端

SpringMVC 配置 spring-mvc.xml

@Controller 定义一个控制器类
@RequestMapping 处理请求地址映射，六个属性
- value 指定请求的实际地址
- method 指定请求的method类型，GET、POST等
- consumes 指定处理请求的提交内容类型（Content-Type），例如application/json, text/html
- produces 指定返回的内容类型Content-Type，仅当request请求头中的(Accept)类型中包含该指定类型才返回, 字符编码charset=UTF-8 解决返回中文乱码。
- params 指定request中必须包含某些参数值
- headers 指定request中必须包含某些指定的header值
@ReqeustBody 用来处理Content-Type: 不是application/x-www-form-urlencoded编码的内容，例如application/json, application/xml等
@ResponseBody 用于将Controller的方法返回的对象，经过适当的HttpMessageConverter转换为指定格式后，写入到Response对象的body数据区，返回的数据不是html标签的页面，而是其余某种格式的数据时（如json、xml等）使用

使用bootstrap+bootstrapTable+Ajax开发，注意bootstrap模态框modal的使用。jquery

注意：引入js时，注意js文件的顺序，必须先引入jquery.js。不然会出现$().bootstrapTable不是一个function的错误。git

数据库

一、建立数据库mssm;github

二、建立表user，建表SQL语句web

CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(255) DEFAULT NULL,
  `password` varchar(255) DEFAULT NULL,
  `nickname` varchar(255) DEFAULT NULL,
  `age` int(11) DEFAULT NULL,
  `sex` int(11) DEFAULT NULL,
  `signature` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=13 DEFAULT CHARSET=utf8;

运行效果图

总结

主要使用Mybatis实现数据库的增删查改操做，同时前台使用bootstrap框架开发页面。
