SSM框架的搭建

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了SSM框架的搭建相关的知识，希望对你有一定的参考价值。
SpringMVC：它用于web层，相当于controller（等价于传统的servlet和struts的action），用来处理用户请求。
Spring：太强大了，以至于我无法用一个词或一句话来概括它。但与我们平时开发接触最多的估计就是IOC容器，它可以装载bean；aop，事务管理等等都是我们经常用到的。
MyBatis：如果你问我它跟鼎鼎大名的Hibernate有什么区别？我只想说，他更符合我的需求。第一，它能自由控制sql，这会让有数据库经验的人（当然不是说我啦~捂脸~）编写的代码能搞提升数据库访问的效率。第二，它可以使用xml的方式来组织管理我们的sql，因为一般程序出错很多情况下是sql出错，别人接手代码后能快速找到出错地方，甚至可以优化原来写的sql。
新建web项目，导包，编写配置文件
1.spring-mybatis.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:p="http://www.springframework.org/schema/p" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd http://www.springframework.org/schema/context 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 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd "> <!-- 扫描注解包 --> <context:component-scan base-package="cn.dao,cn.pojo,cn.service"></context:component-scan> <!-- 配置数据源 --> <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location" value="classpath:jdbc.properties"></property> </bean> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="${driver}"></property> <property name="url" value="${url}"></property> <property name="username" value="${name}"></property> <property name="password" value="${pass}"></property> </bean> <!--配置sqlsessionfactory --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <property name="configLocation" value="classpath:mybatis-config.xml"></property> <property name="typeAliasesPackage" value="cn.pojo"></property> </bean> <!--配置映射器 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="cn.dao"></property> </bean> <!--配置事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean> <!-- 启动事务注解功能 --> <tx:annotation-driven transaction-manager="transactionManager"/> </beans>
其中连接数据库的配置文件jdbc.properties

2.mybatis-config.xml

3.springmvc-servlet.xml
