　　测试Spring

　　　　　　　　　　　　　　　　　　　　　　在index.jsp里面写测试index.jsp

　　　　　　　　　　　　　　　　　　　　　　　　

编写controller

　　　　　　　　　　

 　　　　　　然后在WEB-INF创建pages再创建list.jsp

　　　　　　　　

 

 

 　　　　在controller里面添加@Autowired　　

 　　　　　　

　　　　这里就完成了spring 和springmvc的整合

　　　　进行Mybatis编写

　　　　　　　　　　　　　　　　　　　创建Mybatis核心配置文件SqlMapConfig.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPEconfiguration
PUBLIC"-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
   <!--配置环境-->
<environments default="development">
        <environment id="development">
            <transactionManager type="JDBC"/>
            <dataSource type="POOLED">
                <property name="driver" value="com.mysql.jdbc.Driver"/>
                <property name="url" value="jdbc:mysql://127.0.0.1:3306/ssm?characterEncoding=utf8"/>
                <property name="username" value="root"/>
                <property name="password" value="1234"/>
            </dataSource>
        </environment>
    </environments>
<!--引入映射文件-->
<mappers>
       <package name="com.kun.dao"></package>
    </mappers>
</configuration>

　　

 　　　　　　　　　　　　　　　　接下来进行测试

　　　　　　　　　　　　　　　　　　　　　　　　TestMybatis

import com.kun.dao.AccountDao;
import com.kun.model.Account;
import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.Test;

import java.io.IOException;
import java.io.InputStream;
import java.util.List;


public class TestMyBatis {
    @Test
//    测试查询
public void run1() throws IOException {
//        加载配置文件、
InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");
        //创建SqlSessionFactory对象
SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);
//        创建SqlSession对象
SqlSession session = factory.openSession();
//        获取到代理对象
AccountDao dao = session.getMapper(AccountDao.class);
//        查询所有数据
List<Account> list = dao.findAll();
        for (Account account : list) {
            System.out.println(account);
        }
//        关闭资源
session.close();
        in.close();

    }

    @Test
//    测试添加
public void run2() throws IOException {
        //加载配置文件
InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");
//       创建SqlSessionFactory
SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);
//        创建SqlSession对象
SqlSession session = factory.openSession();
//        获取代理对象
AccountDao dao = session.getMapper(AccountDao.class);
        Account account = new Account();
        account.setName("小孩");
        account.setAge(38);
        dao.save(account);
//        提交数据
session.commit();
//        关闭资源
session.close();
        in.close();
    }
}

 

　　　　测试完成功后在ApplicationContext.xml添加下面的Mybatis连接池，工厂，配置AccountDao接口所在包　　

<!--spring整合MyBatis框架-->
<!--配置连接池-->
<!--数据源-->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql:///ssm"/>
    <property name="username" value="root"/>
    <property name="password" value="1234"/>
</bean>
<!--配置SqlSessionFactory工厂-->
<bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"></property>
</bean>
<!--配置AccountDao接口所在包-->
<bean id="mapperSanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.kun.dao"/>
</bean>


<!--spring配置申明事务管理-->

<!--配置事务管理器-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"/>
</bean>
<!--配置事务通知-->
<tx:advice  id="txAdvice " transaction-manager="transactionManager">
    <tx:attributes>
        <tx:method name="find*" read-only="true"/>
        <tx:method name="*" isolation="DEFAULT"/>
    </tx:attributes>
</tx:advice>
<!--配置aop增强-->
<aop:config>
    <aop:advisor advice-ref="txAdvice " pointcut="execution(* com.kun.service.impl.AccountServiceImpl.*(..))"/>
</aop:config>

下一步在AccountServiceImpl在添加@Autowired

 

 

 到这里spring和Mysbatis整合完成
