SpringMVC+Spring+MyBatis整合完整版Web实例(附数据) 最近段时间正在学习Spring MVC和MyBatis的一些知识。自己也在网络上面找了一些例子来练习。但是都不是很完整。所以，今天，自己也抽空写了个完成的关于Spring MVC + Spring + MyBatis（简称 SSM）的一个CRUD的完整Web 演示例子。如果你也是刚好学习这几个框架的新手，或许我做的这个例子对你刚好有所帮助哦！[caption id="" align="aligncenter" width="275"] 演示工程的目录结构[/caption][caption id="" align="aligncenter" width="550"] 添加数据页面[/caption][caption id="" align="aligncenter" width="550"] 修改数据的页面[/caption][caption id="" align="aligncenter" width="550"] 查询出的数据列表[/caption]下面来说下这个演示的小例子。首先，我是使用MyEclipse工具做的这个例子，整合了Sping 3 、Spring MVC 3 、MyBatis框架，演示数据库采用MySQL数据库。例子中主要操作包括对数据的添加（C）、查找（R）、更新（U）、删除（D）。我在这里采用的数据库连接池是来自阿里巴巴的Druid，至于Druid的强大之处，我在这里就不做过多的解释了，有兴趣的朋友们可以去网上谷歌或者百度一下哦！好了下面我就贴上这次这个演示例子的关键代码：BaseControllerpackage com.bky.controller; import java.util.List; import java.util.UUID; import javax.servlet.http.HttpServletRequest; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import com.bky.model.Add; import com.bky.service.BaseService; @Controller public class BaseController { private BaseService baseService; public BaseService getBaseService() { return baseService; } @Autowired public void setBaseService(BaseService baseService) { this.baseService = baseService; } @SuppressWarnings("finally") @RequestMapping("addInfo") public String add(Add add,HttpServletRequest request){ try { add.setId(UUID.randomUUID().toString()); System.out.println(add.getId() + ":::::" + add.getTname() + ":::::" + add.getTpwd()); String str = baseService.addInfo(add); System.out.println(str); request.setAttribute("InfoMessage", str); } catch (Exception e) { e.printStackTrace(); request.setAttribute("InfoMessage", "添加信息失败！具体异常信息：" + e.getMessage()); } finally { return "result"; } } @RequestMapping("getAll") public String getAddInfoAll(HttpServletRequest request){ try { List<Add> list = baseService.getAll(); System.out.println(list); request.setAttribute("addLists", list); return "listAll"; } catch (Exception e) { e.printStackTrace(); request.setAttribute("InfoMessage", "信息载入失败！具体异常信息：" + e.getMessage()); return "result"; } } @SuppressWarnings("finally") @RequestMapping("del") public String del(String tid,HttpServletRequest request){ try { String str = baseService.delete(tid); request.setAttribute("InfoMessage", str); } catch (Exception e) { e.printStackTrace(); request.setAttribute("InfoMessage", "删除信息失败！具体异常信息：" + e.getMessage()); } finally { return "result"; } } @RequestMapping("modify") public String modify(String tid,HttpServletRequest request){ try { Add add = baseService.findById(tid); request.setAttribute("add", add); return "modify"; } catch (Exception e) { e.printStackTrace(); request.setAttribute("InfoMessage", "信息载入失败！具体异常信息：" + e.getMessage()); return "result"; } } @SuppressWarnings("finally") @RequestMapping("update") public String update(Add add,HttpServletRequest request){ try { String str = baseService.update(add); request.setAttribute("InfoMessage", str); } catch (Exception e) { e.printStackTrace(); request.setAttribute("InfoMessage", "更新信息失败！具体异常信息：" + e.getMessage()); } finally { return "result"; } } }Service的实现package com.bky.service.impl;
