ssi整合，即spring、springmvc、mybatis终极整合，包括一些优化

一、创建一个Web工程

二、导入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与mybatis及springmvc

注意：注释的代码是正常配置的，注释下边的是优化以后的

配置文件如下

myBatis-config.xml文件

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 以为插件生成了这样，认识就好）

package cn.buaa.scm.dao;

import cn.buaa.scm.entity.Supplier;


public interface SupplierMapper extends BaseMapper<Supplier>{
	/**
	 * 添加供应商
	 * @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
	@Autowired
	private SupplierMapper supplierMapper;

	
	public int insert(Supplier supplier) throws Exception {
		return supplierMapper.insert(supplier);
	}

	

	@Override
	public int delete(Supplier entity) {
		return 0;
	}

	@Override
	public Supplier select(Supplier entity) {
		return null;
	}




	@Override
	public int update(Supplier entity) throws Exception {
		// TODO Auto-generated method stub
		return 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 {

	@Resource
	private 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，需要这个注解，这里用来测试环境
	public Object doAjax(Supplier supplier){
		System.out.println("---doAjax.supplier:"+supplier);
		supplier.setSupName("supName1");
		return supplier;
	}

}

index.jsp 框架测试

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

json.jsp  easyUI和jquery测试

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

注意，这些配置要根据自己包名等调整，dao的实现类用xml配置了，直接可以实现，不用在写dao的实现类，有点方法抽取没贴出来，不过不影响整合

这个版本切记在Tomcat7.0以下版本运行，8.0会报错，原因不明。
