一、創(chuàng)建一個Web工程

二、導(dǎo)入jar包到lib下

c3p0-0.9：

mvc_jackson-1.7.2

mybatis_spring

myBatis3.2.2

mysql_driver

spring-3.2-aop

spring-3.2-core

spring-3.2-persistence

spring-3.2-web

三、整合spring與mybatis及springmvc

注意：注釋的代碼是正常配置的，注釋下邊的是優(yōu)化以后的

配置文件如下

myBatis-config.xml文件

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <!-- 通過別名簡化對類的使用 --> <typeAliases><!-- <typeAlias type="cn.buaa.scm.entity.Dept" alias="Dept" /> --><!-- 通過package, 可以直接指定package的名字， mybatis會自動掃描你指定包下面的javabean,并且默認(rèn)設(shè)置一個別名，默認(rèn)的名字為非限定類名來作為它的別名。 --><package name="cn.buaa.scm.entity"/></typeAliases><!-- <mappers><mapper resource="cn/buaa/scm/entity/DeptMapper.xml" /></mappers> --> </configuration>

四、entity及其dao等

SupplierMapper.xml

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" > <mapper namespace="cn.buaa.scm.dao.SupplierMapper"><resultMap id="supplierResultMap" type="cn.buaa.scm.entity.Supplier"><id column="sup_id" property="supId" jdbcType="INTEGER" /><result column="sup_name" property="supName" jdbcType="VARCHAR" /><result column="sup_linkman" property="supLinkman" jdbcType="VARCHAR" /><result column="sup_phone" property="supPhone" jdbcType="VARCHAR" /><result column="sup_address" property="supAddress" jdbcType="VARCHAR" /><result column="sup_remark" property="supRemark" jdbcType="VARCHAR" /></resultMap><insert id="insert" parameterType="Supplier">insert into supplier(sup_name) values (#{supName})</insert> </mapper>

SupplierMapper.java （Dao 以為插件生成了這樣，認(rèn)識就好）

package cn.buaa.scm.dao;import cn.buaa.scm.entity.Supplier;public interface SupplierMapper extends BaseMapper<Supplier>{/*** 添加供應(yīng)商* @param supplier* @return*/}

SupplierServiceImpl.java

package cn.buaa.scm.service.impl;import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service;import cn.buaa.scm.dao.SupplierMapper; import cn.buaa.scm.entity.Supplier; import cn.buaa.scm.service.SupplierService; @Service("supplierService") public class SupplierServiceImpl implements SupplierService {//@Resource@Autowiredprivate SupplierMapper supplierMapper;public int insert(Supplier supplier) throws Exception {return supplierMapper.insert(supplier);}@Overridepublic int delete(Supplier entity) {return 0;}@Overridepublic Supplier select(Supplier entity) {return null;}@Overridepublic int update(Supplier entity) throws Exception {// TODO Auto-generated method stubreturn 0;}} SupplierAction.java

package cn.buaa.scm.action;import javax.annotation.Resource;import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody;import cn.buaa.scm.entity.Supplier; import cn.buaa.scm.service.SupplierService;@Controller @RequestMapping(value="/supplier") public class SupplierAction extends BaseAction {@Resourceprivate SupplierService supplierService;@RequestMapping(value="/insert")public String insert(Supplier supplier){System.out.println("---action.dept:"+supplier);try {supplierService.insert(supplier);} catch (Exception e) {e.printStackTrace();}return "forward:/jsp/main.jsp";}@RequestMapping("/doAjax")@ResponseBody //如果返回json格式，需要這個注解，這里用來測試環(huán)境public Object doAjax(Supplier supplier){System.out.println("---doAjax.supplier:"+supplier);supplier.setSupName("supName1");return supplier;}}

index.jsp 框架測試

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <html> <head> </head> <body><form action="supplier/insert.action" method="post">供應(yīng)商名稱：<input type="text" name="supName"><br> <input type="submit" value="ok"></form> </body> </html> json.jsp ?easyUI和jquery測試

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <html> <head> </head> <body><form action="supplier/insert.action" method="post">供應(yīng)商名稱：<input type="text" name="supName"><br> <input type="submit" value="ok"></form> </body> </html>

注意，這些配置要根據(jù)自己包名等調(diào)整，dao的實現(xiàn)類用xml配置了，直接可以實現(xiàn)，不用在寫dao的實現(xiàn)類，有點方法抽取沒貼出來，不過不影響整合

這個版本切記在Tomcat7.0以下版本運行，8.0會報錯，原因不明。

總結(jié)
