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。
