1 分别编写各个框架的配置
1.1 编写Spring框架配置文件
编写Spring框架的配置文件 applicationContext.xml
<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"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context

<context:component-scan base-package="com.xiaoxi">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
context:component-scan>

编写测试类
public class AccountServiceTest {
@Test
public void testfindAll() {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
AccountService accountService = applicationContext.getBean("accountService", AccountService.class);
accountService.findAll();
}
}
1.2 编写SpringMVC框架配置文件
编写web.xml配置文件
<web-app>
<display-name>Archetype Created Web Applicationdisplay-name>
<filter>
<filter-name>characterEncodingFilterfilter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>
<init-param>
<param-name>encodingparam-name>
<param-value>UTF-8param-value>
init-param>
filter>
<filter-mapping>
<filter-name>characterEncodingFilterfilter-name>
<url-pattern>/*url-pattern>

<servlet>
<servlet-name>dispatcherServletservlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
<init-param>

<load-on-startup>1load-on-startup>

<servlet-mapping>
<servlet-name>dispatcherServletservlet-name>
<url-pattern>/url-pattern>

编写SpringMVC框架的配置文件springmvc.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="com.xiaoxi">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
context:component-scan>
<bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/pages/">property>
<property name="suffix" value=".jsp">property>
bean>
<mvc:resources mapping="/js/**" location="/js/">mvc:resources>
<mvc:resources mapping="/css/**" location="/css">mvc:resources>
<mvc:resources mapping="/images/**" location="/images/">mvc:resources>
<mvc:annotation-driven>mvc:annotation-driven>
beans>
1.3 编写Mybatis框架配置文件
使用注解的方式。
编写sqlMapConfig配置文件
<configuration>
<properties resource="jdbcConfig.properties">properties>
<environments default="mysql">
<environment id="mysql">
<transactionManager type="JDBC">transactionManager>
<dataSource type="POOLED">
<property name="driver" value="${jdbc.driver}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
dataSource>
environment>
environments>
<mappers>
<package name="com.xiaoxi.dao"/>
mappers>
configuration>
jdbcConfig.properties文件中的内容为：
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm_spring?serverTimezone=UTC&characterEncoding=utf8
jdbc.username=root
jdbc.password=xiaoxi123
AccountDao接口不用写实现类
/**
* Account的DAO接口
*/
public interface AccountDao {
@Select("select * from account")
public List<Account> findAll();
@Insert("insert into account (name, money) values (#{name}, #{money})")
public void saveAccount(Account account);
}
编写测试类AccountDaoTest.java
public class AccountDaoTest {
@Test
public void testfindAll() throws Exception{
//加载配置文件
InputStream in = Resources.getResourceAsStream("sqlMapConfig.xml");
//创建SqlSessionFactory工厂对象
SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(in);
//创建SqlSession对象
SqlSession session = sqlSessionFactory.openSession();
//获取代理对象
AccountDao accountDao = session.getMapper(AccountDao.class);
List<Account> accounts = accountDao.findAll();
for(Account account: accounts) {
System.out.println(account);
}
//关闭资源
session.close();
in.close();
}
}
2 Spring整合SpringMVC框架和MyBatis框架
2.1 Spring整合SpringMVC框架
配置监听器实现启动服务时创建容器
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
listener>
<context-param>
<param-name>contextConfigLocationparam-name>
<param-value>classpath:applicationContext.xmlparam-value>
context-param>
2.2 Spring整合MyBatis框架
在applicationContext.xml配置文件中配置
<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"

http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd">
<context:component-scan base-package="com.xiaoxi">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
context:component-scan>
<context:property-placeholder location="classpath:jdbcConfig.properties">context:property-placeholder>
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}">property>
<property name="jdbcUrl" value="${jdbc.url}">property>
<property name="user" value="${jdbc.username}">property>
<property name="password" value="${jdbc.password}">property>
bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource">property>
bean>
<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.xiaoxi.dao">property>
