创建表


create table emps(eid number(5) primary key,ename varchar2(20),esal number(8,2),esex varchar2(2)
);

创建实体


package entity;/*** 员工* @author AdminTC*/
public class Emp {private Integer id;private String name;private Double sal;private String sex;public Emp(){}public Emp(Integer id, String name, Double sal, String sex) {this.id = id;this.name = name;this.sal = sal;this.sex = sex;}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;}public String getSex() {return sex;}public void setSex(String sex) {this.sex = sex;}
}

创建实体与表的映射文件


<?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="empNamespace"><resultMap type="entity.Emp" id="empMap"><id property="id" column="eid"/><result property="name" column="ename"/><result property="sal" column="esal"/><result property="sex" column="esex"/></resultMap>    <!-- 增加员工 --><insert id="add" parameterType="entity.Emp">insert into emps(eid,ename,esal,esex) values(#{id},#{name},#{sal},#{sex})</insert></mapper>

创建Mybatis映射文件配置环境

数据库的信息交由Spring管理！Mybatis配置文件负责加载对应映射文件即可

<mappers><mapper resource="zhongfucheng/entity/EmpMapper.xml"/></mappers>
</configuration>

配置Spring核心过滤器【也是加载总配置文件】

<!-- 核心springmvc核心控制器 --><servlet><servlet-name>DispatcherServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring.xml</param-value></init-param></servlet><servlet-mapping><servlet-name>DispatcherServlet</servlet-name><url-pattern>*.action</url-pattern></servlet-mapping>

配置数据库信息、事务


<?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:tx="http://www.springframework.org/schema/tx"xmlns:aop="http://www.springframework.org/schema/aop"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"><!-- 配置C3P0连接池,目的：管理数据库连接 --><bean id="comboPooledDataSourceID" class="com.mchange.v2.c3p0.ComboPooledDataSource"><property name="driverClass" value="oracle.jdbc.driver.OracleDriver"/><property name="jdbcUrl" value="jdbc:oracle:thin:@127.0.0.1:1521:ZHONGFUCHENG"/><property name="user" value="scott"/><property name="password" value="tiger"/></bean><!-- 配置SqlSessionFactoryBean，目的：加载mybaits配置文件和映射文件，即替代原Mybatis工具类的作用 --><bean id="sqlSessionFactoryBeanID" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="configLocation" value="classpath:mybatis.xml"/><property name="dataSource" ref="comboPooledDataSourceID"/></bean><!-- 配置Mybatis的事务管理器，即因为Mybatis底层用的是JDBC事务管事器，所以在这里依然配置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，即让哪些方法需要事务支持 --><tx:advice id="tx" transaction-manager="dataSourceTransactionManagerID"><tx:attributes><tx:method name="*" propagation="REQUIRED"/></tx:attributes></tx:advice><!-- 配置事务切面，即让哪些包下的类需要事务 --><aop:config><aop:pointcut id="pointcut" expression="execution(* zhongfucheng.service.*.*(..))"/><aop:advisor advice-ref="tx" pointcut-ref="pointcut"/></aop:config><!--扫描注解--><context:component-scan base-package="zhongfucheng"/></beans>

创建Dao、Service、Action


@Repository
public class EmpDao {@Autowiredprivate SqlSessionFactory sqlSessionFactory;/*** 增加员工*/public void add(Emp emp) throws Exception {SqlSession sqlSession = sqlSessionFactory.openSession();sqlSession.insert("empNamespace.add", emp);sqlSession.close();}}

@Service
public class EmpService {@Autowiredprivate zhongfucheng.dao.EmpDao empDao;public void addEmp(Emp emp) throws Exception {empDao.add(emp);}
}


@Controller
@RequestMapping("/emp")
public class EmpAction {@Autowiredprivate EmpService empService;@RequestMapping("/register")public void register(Emp emp) throws Exception {empService.addEmp(emp);System.out.println("注册成功");}}

JSP页面测试
