05（maven+SSM）网上商城项目实战之spring mybatis整合
1.配置POM.xml文件 ,配置项目所需jar
2.配置WEB.xml:
配置spring监听器
<context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:application-context.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>
3.创建anotation.xml配置文件
<!-- spring扫描 @service --> <context:component-scan base-package="cn.liu"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <context:annotation-config/>
4. 创建jdbc.properties和jdbc.xml，并配置：
driverClass=com.mysql.jdbc.Driver
jdbcUrl=jdbc:mysql://localhost:3306/shop?characterEncoding=UTF-8
user=root
password=
<!-- c3p0-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${driverClass}"/>
<property name="jdbcUrl" value="${jdbcUrl}"></property>
<property name="user" value="${user}" />
<property name="password" value="${password}"/>
</bean>
5.配置property.xml文件,读取JDBC配置
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <!-- JDBC的配置 --> <value>classpath:properties/jdbc.properties</value> </list> </property> </bean>
6.配置mybatis.xml文件
<!-- mybatis org.mybatis.spring.SqlSessionFactoryBean 配置 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="mapperLocations" value="classpath:cn/liu/croe/dao/*.xml"/> <property name="typeAliasesPackage" value="cn.liu.croe.bean"></property> </bean> <!-- 扫包 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="cn.liu.croe.dao"/> </bean>
7.事务管理transation.xml:
<!-- spring 事务 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 开启事务注解 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
8.UserInfoDAO.xml
<?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.liu.croe.dao.UserInfoDAO">
<insert id="add" parameterType="UserInfo">
insert into user_info (user_name,user_sex)
values(#{userName},#{userSex})
</insert>
</mapper>
9.事务管理注释:@Transactional
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import cn.liu.croe.bean.UserInfo;
import cn.liu.croe.dao.UserInfoDAO;
import cn.liu.croe.service.IUserInfoService;
@Service
@Transactional
public class UserInfoServiceImpl implements IUserInfoService {
@Autowired
private UserInfoDAO userdao;
public void addUser(UserInfo user) {
int i = userdao.add(user);
System.out.println(i);
throw new RuntimeException("运行时异常");
}
}
10.测试类：
package
cn.shop.userinfo;
import
org.junit.Test;
import
org.junit.runner.RunWith;
import
org.springframework.beans.factory.annotation.Autowired;
import
org.springframework.test.context.ContextConfiguration;
import
org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import
cn.liu.croe.bean.UserInfo;
import
cn.liu.croe.service.IUserInfoService;
@RunWith
(SpringJUnit4ClassRunner.
class
)
@ContextConfiguration
(locations =
"classpath:application-context.xml"
)
public
class
UserTest {
@Autowired
private
IUserInfoService service;
@Test
public
void
testAdd() {
UserInfo user =
new
UserInfo();
user.setUserName(
"秋香"
);
user.setUserSex(
"女"
);
service.addUser(user);
}
}
