SpringMVC+Spring+MyBatis整合完整版Web實例(附數據)

　　最近段時間正在學習Spring MVC和MyBatis的一些知識。自己也在網絡上面找了一些例子來練習。但是都不是很完整。所以，今天，自己也抽空寫了個完成的關於Spring MVC + Spring + MyBatis（簡稱 SSM）的一個CRUD的完整Web 演示例子。如果你也是剛好學習這幾個框架的新手，或許我做的這個例子對你剛好有所幫助哦！

演示工程的目錄結構

添加數據頁面

修改數據的頁面

查詢出的數據列表

　　下面來說下這個演示的小例子。首先，我是使用MyEclipse工具做的這個例子，整合了Sping 3 、Spring MVC 3 、MyBatis框架，演示數據庫采用MySQL數據庫。例子中主要操作包括對數據的添加（C）、查找（R）、更新（U）、刪除（D）。我在這里采用的數據庫連接池是來自阿里巴巴的Druid，至於Druid的強大之處，我在這里就不做過多的解釋了，有興趣的朋友們可以去網上谷歌或者百度一下哦！好了下面我就貼上這次這個演示例子的關鍵代碼：

BaseController：

package 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", "添加信息失敗！具體異常信息：" + 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", "信息載入失敗！具體異常信息：" + 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", "刪除信息失敗！具體異常信息：" + 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", "信息載入失敗！具體異常信息：" + 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", "更新信息失敗！具體異常信息：" + e.getMessage());
        } finally {            
            return "result";
        }
    }

}

Service的實現：

package com.bky.service.impl;

import java.util.List;
import java.util.UUID;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.bky.dao.AddMapper;
import com.bky.model.Add;
import com.bky.service.BaseService;

@Service("baseService")
public class BaseServiceImpl implements BaseService {

    private AddMapper addMapper;

    public AddMapper getAddMapper() {
        return addMapper;
    }
    @Autowired
    public void setAddMapper(AddMapper addMapper) {
        this.addMapper = addMapper;
    }

    @Override
    public String addInfo(Add addInfo) {
        if (addMapper.insertSelective(addInfo) == 1) {
            return "添加成功";
        }
        return "添加失敗";
    }
    @Override
    public List<Add> getAll() {
        return addMapper.getAll();
    }
    @Override
    public String delete(String id) {
        if (addMapper.deleteByPrimaryKey(id) == 1) {
            return "刪除成功";
        }
        return "刪除失敗";
    }
    @Override
    public Add findById(String id) {
        return addMapper.selectByPrimaryKey(id);
    }
    @Override
    public String update(Add addInfo) {
        if (addMapper.updateByPrimaryKeySelective(addInfo) == 1) {
            return "更新成功";
        }
        return "更新失敗";
    }

}

Mapper：

　　以上就是幾個關鍵位置的代碼，我全部貼出來了。至於配置文件什么的，由於時間原因沒有貼出。如果大家要是感興趣的話，可以下載我的這個演示項目包，里面的東西都齊全着，導入到MyEclipse上面直接部署到服務器上面就可以運行。數據庫就是里面的那個.sql文件。建個庫然后將數據導入就是。哦，對了。導完數據后，記得別忘了到config.properties里面去把數據庫的連接信息換成你自己哦！
