spring和mybaits整合

spring + mybatis + mysql/oracle开发

1. 创建一个spring-mybatis-mysql这么一个javaweb或java工程
2. 导入spring-ioc，spring-aop，spring-transaction，mybatis，c3p0，mysql/oracle相关的jar包和spring整合mybatis的jar包
3. 创建students.sql

--mysqlcreate table students(   sid  int(5) primary key,   sname varchar(10),   ssal double(8,2));

4. 创建Student.java

/** * 学生 * @author csx */public class Student {private Integer id;//编号private String name;//姓名private Double sal;//薪水public Student(){}public Student(Integer id, String name, Double sal) {this.id = id;this.name = name;this.sal = sal;}public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public Double getSal() {return sal;}public void setSal(Double sal) {this.sal = sal;}}

5. 创建StudentMapper.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="studentNamespace"><resultMap type="cn.csx.javaee.mybatis.entity.Student" id="studentMap"><id property="id" column="sid" /><result property="name" column="sname"/><result property="sal" column="ssal"/></resultMap><insert id="insert" parameterType="cn.csx.javaee.mybatis.entity.Student">insert into students(sid,sname,ssal) values(#{id},#{name},#{sal})</insert></mapper>

6. 创建StudentDao.java

public class StudentDao {private SqlSessionFactory sqlSessionFactory;public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory) {this.sqlSessionFactory = sqlSessionFactory;}public void insert(Student student){SqlSession sqlSession = sqlSessionFactory.openSession();sqlSession.insert("studentNamespace.insert",student);//int i = 10/0;}public static void main(String[] args) {ApplicationContext ac = new ClassPathXmlApplicationContext(new String[]{"spring.xml"});StudentDao studentDao = (StudentDao) ac.getBean("studentDaoID");studentDao.insert(new Student(1,"哈哈",7000D));}}

7. 在src目录下创建mybatis.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration><mappers><mapper resource="cn/csx/javaee/mybatis/entity/StudentMapper.xml"/></mappers></configuration>

8. 在src目录下创建spring.xml

<?xml version="1.0" encoding="UTF-8"?><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"  xmlns:mvc="http://www.springframework.org/schema/mvc"      xsi:schemaLocation="  http://www.springframework.org/schema/beans   http://www.springframework.org/schema/beans/spring-beans-3.0.xsd    http://www.springframework.org/schema/context      http://www.springframework.org/schema/context/spring-context-3.0.xsd     http://www.springframework.org/schema/aop   http://www.springframework.org/schema/aop/spring-aop-3.0.xsd    http://www.springframework.org/schema/tx      http://www.springframework.org/schema/tx/spring-tx-3.0.xsd          http://www.springframework.org/schema/mvc      http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd              ">      <!-- 配置C3P0连接池(即管理数据库连接) -->      <bean id="comboPooledDataSourceID" class="com.mchange.v2.c3p0.ComboPooledDataSource">      <property name="driverClass" value="com.mysql.jdbc.Driver"/>      <property name="jdbcUrl" value="jdbc:mysql://127.0.0.1:3306/mybatis"/>      <property name="user" value="root"/>      <property name="password" value="root"/>      </bean>                  <!-- 配置SqlSessionFactoryBean(即替代MyBatisUtil工具类的作用) -->      <bean id="sqlSessionFactoryBeanID" class="org.mybatis.spring.SqlSessionFactoryBean">      <property name="dataSource" ref="comboPooledDataSourceID"/>      <property name="configLocation" value="classpath:mybatis.xml"/>      </bean>                  <!-- 配置事务管理器(即使用JDBC事务管理器) -->      <bean id="dataSourceTransactionManagerID" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">      <property name="dataSource" ref="comboPooledDataSourceID"/>      </bean>                  <!-- 配置事务通知(即哪些方法需要事务) -->  <tx:advice id="tx" transaction-manager="dataSourceTransactionManagerID">  <tx:attributes>  <tx:method name="*" propagation="REQUIRED"/>  </tx:attributes>  </tx:advice>                 <!-- 配置事务切面(即哪些包中的类需要事务通知) -->      <aop:config>      <aop:pointcut id="pointcut" expression="execution(* cn.itcast.javaee.mybatis.dao.*.*(..))"/>      <aop:advisor advice-ref="tx" pointcut-ref="pointcut" />      </aop:config>                  <!-- 配置StudentDao类 -->      <bean id="studentDaoID" class="cn.itcast.javaee.mybatis.dao.StudentDao">      <property name="sqlSessionFactory" ref="sqlSessionFactoryBeanID"/>      </bean>      </beans>
