Spring003

第一步：创建BillMapper接口 ，ProviderMapper接口

public interface BillMapper {
    //根据商品名称（模糊查询），供应商id，是否付款  进行查询
    public List getBillByProName(Bill bill);
}

public interface ProviderMapper {

    public List getAllProvider();

}

 第二步:创建他们的实现类

public class BillMapperImpl implements BillMapper{
    private SqlSessionTemplate sqlSessionTemplate;
    public SqlSessionTemplate getSqlSessionTemplate() {
        return sqlSessionTemplate;
    }
    public void setSqlSessionTemplate(SqlSessionTemplate sqlSessionTemplate) {
        this.sqlSessionTemplate = sqlSessionTemplate;
    }
    @Override
    public List getBillByProName(Bill bill) {
        return sqlSessionTemplate.getMapper(BillMapper.class).getBillByProName(bill);
    }
}

package com.MyBatis.dao;

import com.pojo.Provider;
import org.mybatis.spring.SqlSessionTemplate;

import java.util.List;

/**

 */
public class ProviderMapperImpl implements ProviderMapper{

    private SqlSessionTemplate sqlSessionTemplate;

    public SqlSessionTemplate getSqlSessionTemplate() {
        return sqlSessionTemplate;
    }

    public void setSqlSessionTemplate(SqlSessionTemplate sqlSessionTemplate) {
        this.sqlSessionTemplate = sqlSessionTemplate;
    }

    @Override
    public List getAllProvider() {
        return sqlSessionTemplate.getMapper(ProviderMapper.class).getAllProvider();
    }
}

 第三步：创建其对应的映射文件

    
    select b.billCode,b.productName,b.totalPrice,b.isPayment,b.creationDate,p.proName
          from smbms_bill b,smbms_provider p where b.productName like concat('%',#{productName},'%') and b.isPayment=#{isPayment}
          and b.isPayment=#{isPayment} and b.providerId=p.id
  
    
       
       
    

    
        select * from smbms_provider;
    

第四步：创建BillService和ProviderService接口

public interface BillService {
    public List getBillByNameIdIsPay(Bill bill);
}

public interface ProviderService {
    public List getall();
}

 第五步：实现类

package com.spring.service;

import com.MyBatis.dao.BillMapperImpl;
import com.pojo.Bill;

import java.util.List;

/**
 * @auther zll
 * @create 2020/7/16-20:33
 */
public class BillServiceImpl implements BillService {
    private BillMapperImpl billMapper;

    public BillMapperImpl getBillMapper() {
        return billMapper;
    }
    public void setBillMapper(BillMapperImpl billMapper) {
        this.billMapper = billMapper;
    }
    @Override
    public List getBillByNameIdIsPay(Bill bill) {
        return billMapper.getBillByProName(bill);
    }
    
}

package com.spring.service;

import com.MyBatis.dao.ProviderMapper;
import com.pojo.Provider;

import java.util.List;

/**
 * @auther zll
 * @create 2020/7/16-19:38
 */
public class ProviderServiceImpl implements ProviderService {

    private ProviderMapper providerMapper;

    public ProviderMapper getProviderMapper() {
        return providerMapper;
    }

    public void setProviderMapper(ProviderMapper providerMapper) {
        this.providerMapper = providerMapper;
    }

    @Override
    public List getall() {
        return providerMapper.getAllProvider();
    }

}

 第六步：配置applicationContext.xml文件

 第七步：测试

public class TestBill {
    @Test
    public void test(){
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

        BillService p = (BillService) context.getBean("billService");
        List list = new ArrayList<>();
        Bill bill = new Bill();
        bill.setProductName("北");
        bill.setIsPayment(2);

        list = p.getBillByNameIdIsPay(bill);

        for (Bill p1 : list){
            System.out.println(p1.toString());
        }
    }

}

public class TestProvider {
    @Test
    public void test(){
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

        ProviderService p = (ProviderService) context.getBean("providerService");
        List list = new ArrayList<>();

        list = p.getall();

        for (Provider p1 : list){
            System.out.println(p1.toString());
        }
    }

}
