3.在web.xml中配置spring的核心监听器和SpringMVC的servlet
核心代码如下
<!--spring核心监听器-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:applicationContext.xml
</param-value>
</context-param>
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<!--拦截所有请求-->
<url-pattern>/</url-pattern>
</servlet-mapping>
4.创建实体类,编写实体类映射文件xxxMapper.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="com.mipo.dao.UserDao">
<!-- 查询单条纪录 -->
<select id="getUser" parameterType="Integer" resultType="com.mipo.entity.User">
select * from user u where u.uid = #{uid}
</select>
<!-- 根据用户名和密码查询用户 -->
<select id="findUserByNameAndPassword" resultType="com.mipo.entity.User">
select * from user u where u.uName=#{param1} and u.pwd=#{param2}
</select>
</mapper>
5.创建myBatis核心映射配置文件mybatis-config.xml
核心代码如下
<?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>
<!-- 配置映射文件 -->
<mapper resource="com/mipo/entity/UserMapper.xml"/>
</mappers>
</configuration>
5.整合Spring-myBatis创建Spring核心配置文件applicationContext.xml
核心代码如下
<?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:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/context/spring-context-4.1.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-4.1.xsd">
<!--支持注解 -->
<context:annotation-config/>
<!-- 组件扫描 -->
<context:component-scan base-package="com.mipo">

</context:component-scan>
<!-- 读取数据库属性资源文件(明文) -->
<!-- <context:property-placeholder location="classpath:db.properties" /> -->
<!-- 读取数据库加密属性资源文件(加密) -->
<bean id="myPropertyConfigurer"

<property name="locations">
<list><value>classpath:en_db.properties</value></list>
</property>
<property name="fileEncoding" value="UTF-8"/>
<property name="keyLocation" value="classpath:key.k" />
</bean>
<!-- 定义数据源 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>
<!-- 配置SqlSessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!--引入数据源 -->
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:mybatis-config.xml" />
</bean>
<!-- 事务管理 -->

<property name="dataSource" ref="dataSource" />
</bean>
<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>
</beans>
6.在WEB-INF目录下创建springMVC的核心配置文件dispatcher-servlet.xml
核心代码如下
<?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"

http://www.springframework.org/schema/context/spring-context-4.1.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">
<!-- 注册组件 -->
<mvc:annotation-driven />
<context:component-scan base-package="com.mipo.controller">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!--静态方法过滤 -->
<mvc:default-servlet-handler/>
<!--视图管理器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
7.测试spring和myBatis的整合,编写测试类
package com.mipo;
import org.junit.AfterClass;
import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.mipo.service.UserService;
public class TestDemo {
private static ClassPathXmlApplicationContext applicationContext = null;
@BeforeClass
public static void setUpBeforeClass() throws Exception {
applicationContext = new ClassPathXmlApplicationContext(new String[] { "applicationContext.xml" });
}
@AfterClass
public static void tearDownAfterClass() throws Exception {
applicationContext.close();
}
@Test
public void test() {
UserService userService = applicationContext.getBean("userService", UserService.class);
System.out.println(userService.getUser(1).getuName());
}
}
1.使用maven创建一个工程项目
2.在prom.xml中引入核心架包依赖
1.myBatis
2.mybatis-spring
3.mysql
4.commons-dbcp
5.spring-orm
6.spring-webmvc
7.slf4j-log4j12
