010杰信-创建购销合同Excel报表系列-3-建立合同货物（增删改查）：子表

前面分析过购销合同的Excel报表需要四张表，这篇讲的是合同货物表。

这个合同货物表是合同表

项目结构：

前面带红色框框的就是这个需要的domain->Dao层->Service层->到控制层。

具体代码如下：

domain就是数据库中对应的CONTRACT_PRODUCT_C这张表。

如下：

所以domain包中的po类就是：

package cn.itcast.jk.domain;
   //合同货物
public class ContractProduct {
    private String id;// 主键

    private String contractid;// 外键，在这里就是普通的键；
    private String factoryid;

    private String factoryname;//厂家名称
    private String productno;//货号
    private String productimage;//货物照片
    private String productdesc;//货物描述
    private String cnumber;//数量
    private String outnumber;//实际出货数量
    private String loadingrate;//装率
    private String boxnum;//箱数
    private String packingunit;//包装单位
    private String price;//单价
    private String amount;//总金额
    private String finished;//是否出货完毕
    private String exts;//附件
    private String orderno;//排序号
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getContractid() {
        return contractid;
    }
    public void setContractid(String contractid) {
        this.contractid = contractid;
    }
    public String getFactoryid() {
        return factoryid;
    }
    public void setFactoryid(String factoryid) {
        this.factoryid = factoryid;
    }
    public String getFactoryname() {
        return factoryname;
    }
    public void setFactoryname(String factoryname) {
        this.factoryname = factoryname;
    }
    public String getProductno() {
        return productno;
    }
    public void setProductno(String productno) {
        this.productno = productno;
    }
    public String getProductimage() {
        return productimage;
    }
    public void setProductimage(String productimage) {
        this.productimage = productimage;
    }
    public String getProductdesc() {
        return productdesc;
    }
    public void setProductdesc(String productdesc) {
        this.productdesc = productdesc;
    }
    public String getCnumber() {
        return cnumber;
    }
    public void setCnumber(String cnumber) {
        this.cnumber = cnumber;
    }
    public String getOutnumber() {
        return outnumber;
    }
    public void setOutnumber(String outnumber) {
        this.outnumber = outnumber;
    }
    public String getLoadingrate() {
        return loadingrate;
    }
    public void setLoadingrate(String loadingrate) {
        this.loadingrate = loadingrate;
    }
    public String getBoxnum() {
        return boxnum;
    }
    public void setBoxnum(String boxnum) {
        this.boxnum = boxnum;
    }
    public String getPackingunit() {
        return packingunit;
    }
    public void setPackingunit(String packingunit) {
        this.packingunit = packingunit;
    }
    public String getPrice() {
        return price;
    }
    public void setPrice(String price) {
        this.price = price;
    }
    public String getAmount() {
        return amount;
    }
    public void setAmount(String amount) {
        this.amount = amount;
    }
    public String getFinished() {
        return finished;
    }
    public void setFinished(String finished) {
        this.finished = finished;
    }
    public String getExts() {
        return exts;
    }
    public void setExts(String exts) {
        this.exts = exts;
    }
    public String getOrderno() {
        return orderno;
    }
    public void setOrderno(String orderno) {
        this.orderno = orderno;
    }

}

Dao层的代码：

就是BaseDaoImpl.java 的代码：

package cn.itcast.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.itcast.jk.dao.BaseDao;
import cn.itcast.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);
    }
}

Service层：

package cn.itcast.jk.service.impl;

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

import javax.annotation.Resource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import cn.itcast.jk.dao.ContractProductDao;
import cn.itcast.jk.domain.Contract;
import cn.itcast.jk.domain.ContractProduct;
import cn.itcast.jk.pagination.Page;
import cn.itcast.jk.service.ContractProductService;
@Service
public class ContractProductServiceImpl implements ContractProductService{
    @Resource
    ContractProductDao contractProductDao;

@Override
public List<ContractProduct> findPage(Page page) {
    return contractProductDao.findPage(page);
}

@Override
public List<ContractProduct> find(Map paraMap) {

    return contractProductDao.find(paraMap);
}

@Override
public ContractProduct get(Serializable id) {
    return contractProductDao.get(id);
}

@Override
public void insert(ContractProduct contractproduct) {
    contractproduct.setId(UUID.randomUUID().toString());
    contractProductDao.insert(contractproduct);

}

@Override
public void update(ContractProduct contractproduct) {
    contractProductDao.update(contractproduct);
}

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

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

}
