【springmvc+mybatis项目实战】杰信商贸-13.购销合同列表

我们接下来开始编写购销合同的列表业务

首先我们现往我们的FACTORY_C和基础表中倒入一些数据方便我们测试
导入数据的SQL文件： jk.sql (点击下载)
然后我们看到数据已经插入

启动服务器查看我们的数据已经插入


接下来我们开始做购销合同的业务。首先我们的数据库表已经建立(CONTRACT_C)，我们首先创建购销合同的实体类Contract.java:

package cn.hpu.jk.domain;

import java.util.Date;

public class Contract {
	private String id;
	private String offeror;//收购方
	private String contractNo;//合同编号
	private java.util.Date signingDate;//签单日期
	private String inputBy;//制单人
	private String checkBy;//审单人
	private String inspector;//验货员
	private Double totalAmount;//总金额
	private Integer importNum;//重要程度
	private String crequest;//要求
	private String customName;
	private java.util.Date deliveryPeriod;//交货期限
	private java.util.Date shipTime;//船期
	private String tradeTerms;//贸易条款
	private String remark;//说明
	private String printStyle;//打印版式
	private Integer oldState;//归档前状态
	private Integer state;//状态
	private Integer outState;//走货状态
	private String createBy;
	private String creatDept;
	private java.util.Date creatTime;
	
	//get与set方法省略
}

然后建立我们的购销合同的Mapper映射文件ContractMapper.xml，编写后期需要使用的resultMap:

<?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.hpu.jk.mapper.COntractMapper">
	<resultMap type="cn.hpu.jk.domain.Contract" id="contractRM">
		<id property="id" column="CONTRACT_ID"/>
		<result property="offeror" column="OFFEROR"/>
		<result property="contractNo" column="CONTRACT_NO"/>
		<result property="signingDate" column="SIGNING_DATE"/>
		<result property="inputBy" column="INPUT_BY"/>
		<result property="checkBy" column="CHECK_BY"/>
		<result property="inspector" column="INSPECTOR"/>
		<result property="totalAmount" column="TOTAL_AMOUNT"/>
		<result property="importNum" column="IMPORT_NUM"/>
		<result property="crequest" column="CREQUEST"/>
		<result property="customName" column="CUSTOM_NAME"/>
		<result property="deliveryPeriod" column="DELIVERY_PERIOD"/>
		<result property="shipTime" column="SHIP_TIME"/>
		<result property="tradeTerms" column="TRADE_TERMS"/>
		<result property="remark" column="REMARK"/>
		<result property="printStyle" column="PRINT_STYLE"/>
		<result property="oldState" column="OLD_STATE"/>
		<result property="state" column="STATE"/>
		<result property="outState" column="OUT_STATE"/>
		
		<result property="createBy" column="CREATE_BY"/>
		<result property="creatDept" column="CREATE_DEPT"/>
		<result property="creatTime" column="CREATE_TIME"/>
	</resultMap>
</mapper>

接下来我们在ContractMapper.xml中添加增删改查语句:

<!-- 查询多个 -->
<select id="find" parameterType="map" resultMap="contractRM">
	select * from contract_c
	where 1=1
</select>


<!-- 查询一个 -->
<select id="get" parameterType="string" resultMap="contractRM">
	select * from contract_c
	where contract_id=#{id}
</select>


<!-- 新增 -->
<insert id="insert" parameterType="cn.hpu.jk.domain.Contract">
	insert into contract_c
	(CONTRACT_ID,,OFFEROR,CONTRACT_NO,SIGNING_DATE,INPUT_BY,CHECK_BY,INSPECTOR,TOTAL_AMOUNT,
	IMPORT_NUM,CREQUEST,CUSTOM_NAME,DELIVERY_PERIOD,SHIP_TIME,TRADE_TERMS,REMARK,PRINT_STYLE,
	OLD_STATE,STATE,OUT_STATE,CREATE_BY,CREATE_DEPT,CREATE_TIME)
	values
	(
		#{id},
		#{offeror, jdbcType=VARCHAR},
		#{contractNo, jdbcType=VARCHAR},
		#{signingDate, jdbcType=TIMESTAMP},
		#{inputBy, jdbcType=VARCHAR},
		#{checkBy, jdbcType=VARCHAR},
		#{inspector, jdbcType=VARCHAR},
		#{totalAmount, jdbcType=DOUBLE},
		#{importNum, jdbcType=INTEGER},
		#{crequest, jdbcType=VARCHAR},
		#{customName, jdbcType=VARCHAR},
		#{deliveryPeriod, jdbcType=TIMESTAMP},
		#{shipTime, jdbcType=TIMESTAMP},
		#{tradeTerms, jdbcType=VARCHAR},
		#{remark, jdbcType=VARCHAR},
		#{printStyle, jdbcType=CHAR},
		#{oldState, jdbcType=INTEGER},
		#{state, jdbcType=INTEGER},
		#{outState, jdbcType=INTEGER},
		#{createBy, jdbcType=VARCHAR},
		#{creatDept, jdbcType=VARCHAR},
		#{creatTime, jdbcType=TIMESTAMP}
	)
</insert>


<!-- 修改 -->
<update id="update" parameterType="cn.hpu.jk.domain.Contract">
	update contract_c
	<set>
		<if test="offeror != null">OFFEROR=#{offeror},</if>
		<if test="contractNo != null">CONTRACT_NO=#{contractNo},</if>
		<if test="signingDate != null">SIGNING_DATE=#{signingDate},</if>
		<if test="inputBy != null">INPUT_BY=#{inputBy},</if>
		<if test="checkBy != null">CHECK_BY=#{checkBy},</if>
		<if test="inspector != null">INSPECTOR=#{inspector},</if>
		<if test="totalAmount != null">TOTAL_AMOUNT=#{totalAmount},</if>
		<if test="importNum != null">IMPORT_NUM=#{importNum},</if>
		<if test="crequest != null">CREQUEST=#{crequest},</if>
		<if test="customName != null">CUSTOM_NAME=#{customName},</if>
		<if test="deliveryPeriod != null">DELIVERY_PERIOD=#{deliveryPeriod},</if>
		<if test="shipTime != null">SHIP_TIME=#{shipTime},</if>
		<if test="tradeTerms != null">TRADE_TERMS=#{tradeTerms},</if>
		<if test="remark != null">REMARK=#{remark},</if>
		<if test="printStyle != null">PRINT_STYLE=#{printStyle},</if>
		<if test="oldState != null">OLD_STATE=#{oldState},</if>
		<if test="state != null">STATE=#{state},</if>
		<if test="outState != null">OUT_STATE=#{outState},</if>
	</set>
	where contract_id=#{id}
</update>


<!-- 删除一条 -->
<delete id="deleteById" parameterType="string">
	delete from contract_c
	where CONTRACT_ID=#{id}
</delete>


<!-- 删除多条(一维字符串数组的形式) -->
<delete id="delete" parameterType="string">
	delete from contract_c
	where CONTRACT_ID in  
	<foreach collection="array" item="id" open="(" close=")" separator=",">
		#{id}
	</foreach>
</delete>


<!-- 修改状态 -->
<update id="updateState" parameterType="map">
	update contract_c set state=#{state}
	where CONTRACT_ID in
	<foreach collection="ids" item="id" open="(" close=")" separator=",">
		#{id}
	</foreach>
</update>

接下来我们来编写Dao层
ContractDao.java:

package cn.hpu.jk.dao;

import java.util.Map;

import cn.hpu.jk.domain.Contract;

public interface ContractDao extends BaseDao<Contract>{
	//我们这里可以直接使用继承的BaseDao的增删改查方法
	//创建一系列其它Dao的原因是因为其它Dao有可能需要拓展
	
	public void updateState(Map map);//修改状态
}

ContractDaoImpl.java:

package cn.hpu.jk.dao.impl;

import java.util.Map;

import org.springframework.stereotype.Repository;

import cn.hpu.jk.dao.ContractDao;
import cn.hpu.jk.domain.Contract;

@Repository //为了包扫描的时候这个Dao被扫描到
public class ContractDaoImpl extends BaseDaoImpl<Contract> implements ContractDao{
	
	public ContractDaoImpl(){
		//设置命名空间
		super.setNs("cn.hpu.jk.mapper.ContractMapper");
	}


	@Override
	public void updateState(Map map) {
		super.getSqlSession().update(super.getNs()+".updateState", map);
	}
}

回顾一下其中的BaseDao与 BaseDaoImpl
BaseDao.java:

package cn.hpu.jk.dao;


import java.io.Serializable;
import java.util.List;
import java.util.Map;


import cn.hpu.jk.pagination.Page;


/**
 * @Description: 泛型类，基础的DAO接口
 * @Author:	nutony
 * @Company:	http://java.itcast.cn
 * @CreateDate:	2014-2-25
 */
public interface BaseDao<T> {
	public List<T> findPage(Page page);				//分页查询
	public List<T> find(Map paraMap);				//带条件查询，条件可以为null，既没有条件；返回list对象集合
	public T get(Serializable id);					//只查询一个，常用于修改
	public void insert(T entity);					//插入，用实体作为参数
	public void update(T entity);					//修改，用实体作为参数
	public void deleteById(Serializable id);		//按id删除，删除一条；支持整数型和字符串类型ID
	public void delete(Serializable[] ids);			//批量删除；支持整数型和字符串类型ID
}

BaseDaoImpl.java:

package cn.hpu.jk.dao.impl;

import java.io.Serializable;
import java.util.List;
import java.util.Map;

import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.support.SqlSessionDaoSupport;
import org.springframework.beans.factory.annotation.Autowired;


import cn.hpu.jk.dao.BaseDao;
import cn.hpu.jk.pagination.Page;


public abstract class BaseDaoImpl<T> extends SqlSessionDaoSupport implements BaseDao<T>{
	@Autowired
	//mybatis-spring 1.0无需此方法；mybatis-spring1.2必须注入。
	public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory){
		super.setSqlSessionFactory(sqlSessionFactory);
	}
	
	private String ns;		//命名空间
	public String getNs() {
		return ns;
	}
	public void setNs(String ns) {
		this.ns = ns;
	}
	
	public List<T> findPage(Page page){
		List<T> oList = this.getSqlSession().selectList(ns + ".findPage", page);
		return oList;
	}


	public List<T> find(Map map) {
		List<T> oList = this.getSqlSession().selectList(ns + ".find", map);
		return oList;
	}
	public T get(Serializable id) {
		return this.getSqlSession().selectOne(ns + ".get", id);
	}


	public void insert(T entity) {
		this.getSqlSession().insert(ns + ".insert", entity);
	}


	public void update(T entity) {
		this.getSqlSession().update(ns + ".update", entity);
	}


	public void deleteById(Serializable id) {
		this.getSqlSession().delete(ns + ".deleteById", id);
	}


	public void delete(Serializable[] ids) {
		this.getSqlSession().delete(ns + ".delete", ids);
	}
}

接下来我们来编写Service层
ContractService.java:

package cn.hpu.jk.service;


import java.io.Serializable;
import java.util.List;
import java.util.Map;


import cn.hpu.jk.domain.Contract;
import cn.hpu.jk.pagination.Page;


public interface ContractService {
	public List<Contract> findPage(Page page);	//分页查询
	public List<Contract> find(Map paraMap);		//带条件查询，条件可以为null，既没有条件；返回list对象集合
	public Contract get(Serializable id);				//只查询一个，常用于修改
	public void insert(Contract contract);		//插入，用实体作为参数
	public void update(Contract contract);		//修改，用实体作为参数
	public void deleteById(Serializable id);	//按id删除，删除一条；支持整数型和字符串类型ID
	public void delete(Serializable[] ids);	//批量删除；支持整数型和字符串类型ID

	public void submit(Serializable[] ids);//已上报
        public void cancel(Serializable[] ids);//草稿
}

ContractServiceImpl.java:

package cn.hpu.jk.service.impl;

import java.io.Serializable;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.UUID;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;


import cn.hpu.jk.dao.ContractDao;
import cn.hpu.jk.domain.Contract;
import cn.hpu.jk.pagination.Page;
import cn.hpu.jk.service.ContractService;


@Service
public class ContractServiceImpl implements ContractService{
	
	@Resource
	ContractDao contractDao;
	


	@Override
	public void delete(Serializable[] ids) {
		contractDao.delete(ids);
	}


	@Override
	public void deleteById(Serializable id) {
		contractDao.deleteById(id);
	}


	@Override
	public List<Contract> find(Map paraMap) {
		return contractDao.find(paraMap);
	}


	@Override
	public List<Contract> findPage(Page page) {
		// TODO Auto-generated method stub
		return null;
	}


	@Override
	public Contract get(Serializable id) {
		return contractDao.get(id);
	}


	@Override
	public void insert(Contract contract) {
		//设置UUID
		contract.setId(UUID.randomUUID().toString());
		contract.setState(0);//默认为草稿
		contractDao.insert(contract);
	}


	@Override
	public void update(Contract contract) {
		
		contractDao.update(contract);
	}


	@Override
	public void submit(Serializable[] ids) {
		//默认刚建完的是草稿，建完之后确定没问题就上报
		//0草稿 1已上报
		 Map map=new HashMap();
		 map.put("state",1);//1已上报
		 map.put("ids", ids);
		 
		 contractDao.updateState(map);
	}


	@Override
	public void cancel(Serializable[] ids) {
		 Map map=new HashMap();
		 map.put("state",0);//0
		 map.put("ids", ids);
		 
		 contractDao.updateState(map);
	}


}

然后在beans-service.xml增加contractService的注入

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans

		<!-- 加载service-->	
		<bean name="factoryService" class="cn.hpu.jk.service.impl.FactoryServiceImpl"/>
		<bean name="contractService" class="cn.hpu.jk.service.impl.ContractServiceImpl"/>
</beans> 

接下来我们来编写Controller层

package cn.hpu.jk.controller.cargo.contract;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;


import cn.hpu.jk.controller.BaseController;
import cn.hpu.jk.domain.Contract;
import cn.hpu.jk.service.ContractService;


@Controller
public class ContractController extends BaseController{
	
	@Autowired
	ContractService contractService;
	
	@RequestMapping("/cargo/contract/list.action")
	public String list(Model model){
		List<Contract> datalist=contractService.find(null);
		model.addAttribute("datalist",datalist);
	
		return "/cargo/contract/jContractList.jsp";
	}
}

我们先写了一个获取购销合同的方法，所以我们写一个购销合同列表显示的jsp页面,我们在src/main/webapp/WEBINF/pages/cargo/contract/下创建jContractList.jsp:

<%@ page language="java" pageEncoding="UTF-8"%>
<%@ include file="../../baselist.jsp"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt"  prefix="fmt"%>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
	<title></title>
</head>

<body>
<form name="icform" method="post">


<div id="menubar">
<div id="middleMenubar">
<div id="innerMenubar">
  <div id="navMenubar">
  
	<ul>
	<li id="view"><a href="#" onclick="formSubmit('toview.action','_self');this.blur();">查看</a></li>
	<li id="new"><a href="#" onclick="formSubmit('tocreate.action','_self');this.blur();">添加</a></li>
	<li id="update"><a href="#" onclick="formSubmit('toupdate.action','_self');this.blur();">修改</a></li>

	</ul>


  </div>
</div>
</div>
</div>
   
<!-- 页面主体部分（列表等） -->  
<div class="textbox" id="centerTextbox">
  <div class="textbox-header">
  <div class="textbox-inner-header">
  <div class="textbox-title">
  	销售合同列表
  </div> 
  </div>
  </div>
  
<div>
<div class="eXtremeTable" >
<table id="ec_table" class="tableRegion" width="98%" >
	<thead>
	<tr>
		<td class="tableHeader"><input type="checkbox" name="selid" onclick="checkAll('id',this)"></td>
		<td class="tableHeader">序号</td>

		<td class="tableHeader">总金额</td>
		<td class="tableHeader">状态</td>
	</tr>
	</thead>
	<tbody class="tableBody" >
	
	<c:forEach items="${datalist}" var="o" varStatus="status">
	<tr class="odd" onmouseover="this.className='highlight'" onmouseout="this.className='odd'" >

		<td>
			<c:if test="${o.state==1}"><font color="green">已上报</font></c:if>
			<c:if test="${o.state==0}">草稿</a></c:if>
		</td>
	</tr>
	</c:forEach>
	
	</tbody>
</table>
</div>
 
</div>
 
 
</form>
</body>
</html>

我们的主界面用的是框架，所以我们在点击货运管理的时候在左侧添加相应功能，


我们在这里修改left.jsp：


修改之后的代码：

<pre name="code" class="html"><%@ page language="java" pageEncoding="UTF-8"%>
<%@ include file="../baselist.jsp" %>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title></title>
	<script type="text/javascript" src="${ctx}/components/jquery-ui/jquery-1.2.6.js"></script>
</head>
 
<body id="left_frame">
<div class="PositionFrame_black" id="PositionFrame"></div>
 
 
<!-- begin1  -->
<div id="sidebar" class="sidebar">
	<div class="sidebar_t">
		<div class="sidebar_t_l"></div>
		<div class="sidebar_t_c"></div>
		<div class="sidebar_t_r"></div>
	</div>
        <div class="panel">
        <div class="panel_icon"><img src="${ctx}/skin/default/images/icon/document_into.png"/></div>
        <div class="panel-header">

        <div class="panel-content">

        </div>
        </div>
    </div>
    <div class="sidebar_t">
		<div class="sidebar_b_l"></div>
		<div class="sidebar_t_c"></div>
		<div class="sidebar_b_r"></div>
	</div>  
</div>
</body>
</html>	

我们在数据库添加一些测试数据，看看能不能获取到数据:

insert into CONTRACT_C (CONTRACT_ID, OFFEROR, CONTRACT_NO, SIGNING_DATE, INPUT_BY, CHECK_BY, INSPECTOR, TOTAL_AMOUNT, IMPORT_NUM, CREQUEST, CUSTOM_NAME, DELIVERY_PERIOD, SHIP_TIME, TRADE_TERMS, REMARK, PRINT_STYLE, OLD_STATE, STATE, OUT_STATE, CREATE_BY, CREATE_DEPT, CREATE_TIME)
values ('22a2e6ab-9711-44ec-adc7-f3b43425765c', '杰信商贸有限公司', '2', to_timestamp('06-10-2014 00:00:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), null, null, null, null, 3, null, '1', to_timestamp('15-10-2014 00:00:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), to_timestamp('05-11-2014 00:00:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), null, null, '2', null, 0, null, null, null, null);
insert into CONTRACT_C (CONTRACT_ID, OFFEROR, CONTRACT_NO, SIGNING_DATE, INPUT_BY, CHECK_BY, INSPECTOR, TOTAL_AMOUNT, IMPORT_NUM, CREQUEST, CUSTOM_NAME, DELIVERY_PERIOD, SHIP_TIME, TRADE_TERMS, REMARK, PRINT_STYLE, OLD_STATE, STATE, OUT_STATE, CREATE_BY, CREATE_DEPT, CREATE_TIME)

commit;

点击“货运管理”之后点击“购销合同”


之后获得数据

如果显示我们输入的测试数据，证明获取“购销合同”列表成功！
