maven：Maven是一个项目管理和综合工具，基于POM的概念来管理项目。
主要的功能就我看来：1.jar的统一，同时寻找jar的依赖 2.热编译，热部署 在项目运行中，修改代码可被服务器接受，不需要重新部署。
基于maven的ssm项目配置及测试，GO
一：新建一个maven项目
点击new mavne project,勾选创建一个简单的项目
Group Id可以理解为总项目名称 Artifact Id 模块名称 Version版本号 Packaging 打包方式 web项目选择war
二：配置pom.xml
pom.xml主要配置的为jar包坐标，来进行jar包的下载及引入

</project>三：配置其余xml
将配置文件，包创建好
第一步，先配置web.xml
配置的关键：springmvc的核心控制器，编码过滤，spring容器的启动
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<!--Spring容器的启动-->
<!-- 监听器的配置 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--applicationContext的配置 默认路径为WEB-INF/applicationContext.xml -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- 编码过滤器，防止乱码问题 -->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param> <init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!--SpringMVC的核心控制器-->
<servlet>
<servlet-name>SpringMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 配置SpringMVC下的配置文件位置及名称 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
<!-- servlet本来是请求时才会创建，这个属性将创建提前 -->
</servlet>
<servlet-mapping>
<servlet-name>SpringMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>第二步：springmvc.xml
配置的关键：注解的启动，视图解析器，静态资源的访问
<?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:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
<!-- 自动扫描controller包下的所有类，使其认为是spring mvc的控制器 路径即为类路径 -->
<context:component-scan
base-package="controller" />
<!-- 静态资源可访问的设置方式 -->
<mvc:default-servlet-handler />
<!-- 注册MVC注解驱动 -->
<mvc:annotation-driven />
<!-- 配置视图解析器 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/"></property> <!-- 这里的两项可以选择不写 -->
<property name="suffix" value=".jsp"></property>
</bean>
</beans>第三部:applicationContext.xml的配置
主要配置：spring-mybatis的集成，通知，注解
<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:util="http://www.springframework.org/schema/util"
xmlns:p="http://www.springframework.org/schema/p"
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/util
http://www.springframework.org/schema/util/spring-util-3.0.xsd">
<!-- 引入外部数据源配置信息 -->
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<value>classpath:mysql.properties</value>
</property>
</bean>
<!-- 配置数据源 -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driver}"></property>
<property name="url" value="${jdbc.url}"></property>
<property name="username" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>
<!-- 配置Session工厂 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<!-- 加载mybatis.cfg.xml文件 -->
<property name="configLocation" value="classpath:mybatis.cfg.xml"></property>
</bean>
<!-- 自动扫描所有的Mapper,在dao包下寻找 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="dao"></property>
</bean>
<!-- 扫描 -->
<context:component-scan base-package="dao,controller,service"></context:component-scan>
<!-- 事务管理 -->
<!-- 配置事务管理器,管理数据源事务处理-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<!-- 配置事务通知 -->
<tx:advice id="advice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="add*" propagation="REQUIRED" rollback-for="Exception"/>
<tx:method name="update*" propagation="REQUIRED" rollback-for="Exception"/>
<tx:method name="delete*" propagation="REQUIRED" rollback-for="Exception"/>
<tx:method name="*" propagation="SUPPORTS"/>
</tx:attributes>
</tx:advice>
<!--service层搞个切点织入通知 -->
<aop:config>
<aop:advisor advice-ref="advice" pointcut="execution(* service.UserService.*(..))"/>
</aop:config>
</beans>第四步：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>
</configuration>log4j真是不进行配置
四：测试
测试内容：从数据库的查询，从页面到Controller,测试内容与原生的ssm项目一样，就不在此赘述。
