【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:

[java] view
plaincopy

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:

[html] view
plaincopy

<?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:

[html] view
plaincopy

<!-- 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:

[java] view
plaincopy

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:

[java] view
plaincopy

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:

[java] view
plaincopy

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:

[java] view
plaincopy

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:

[java] view
plaincopy

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:

[java] view
plaincopy

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

[html] view
plaincopy

<?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
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd ">

<!-- 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

[java] view
plaincopy

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:

[html] view
plaincopy

<%@ page language="java" pageEncoding="UTF-8"%>

<%@ include file="../../baselist.jsp"%>

<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt"%>

<body>

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

</ul>

</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>

<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>

<tbody class="tableBody" >

</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：

[html] view
plaincopy

<pre name="code" class="html"><%@ page language="java" pageEncoding="UTF-8"%>

<%@ include file="../baselist.jsp" %>

<html xmlns="http://www.w3.org/1999/xhtml">

<!-- 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="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:

[sql] view
plaincopy

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！
