基于SSM框架的web入门项目(三)学习记录

配合哔哩哔哩视频学习【SSM 框架】SpringMVC+Spring+Mybatis SSM 整合+实战+源码11集

3.MyBatis整合Spring-没有Mapper实现类

3.1.删除CustomerMapperImpl类

3.2.修改applicationContext.xml

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	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.xsd

	<context:property-placeholder location="classpath:jdbc.properties"/>
	
	
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
		<property name="url" value="${jdbc.url}"/>
		<property name="driverClassName" value="${jdbc.driverClass}"/>
		<property name="username" value="${jdbc.user}"/>
		<property name="password" value="${jdbc.password}"/>
		<property name="maxActive" value="10"/>
		<property name="maxIdle" value="5"/>
	bean>	
	
	
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		
		<property name="dataSource" ref="dataSource"/>
		
		<property name="mapperLocations" value="classpath:mapper/*.xml"/>
	bean>
	
		
	<bean id="customerMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
		
		<property name="mapperInterface" value="com.ssm.dao.CustomerMapper"/>
		
		<property name="sqlSessionFactory" ref="sqlSessionFactory"/>
	bean>
	
beans>

3.3.测试类

package com.ssm.test;

import java.io.IOException;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.ssm.dao.CustomerMapper;
import com.ssm.domain.Customer;



public class MyBatisSpringTest {
	@org.junit.Test
	public void Test() throws IOException
	{
		//1.加载spring配置
		
		ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
		
		//2.获取对象
		CustomerMapper customerMapper = (CustomerMapper)ac.getBean("customerMapper");
		
		//3.调用父类方法
		Customer customer = new Customer();
		customer.setName("老王");
		customer.setGender("男");
		customer.setTelephone("020-88888");
		customer.setAddress("北京青鸟");
		
		customerMapper.saveCustomer(customer);
	
	}
}

结果：
