虽然现在流行SpringBoot了，但是对于以前的SSM配置地狱的框架搭建整合做一个简单的Demo
首先创建新的项目，选择Maven管理我们的依赖 如图所示：
当然我是为了做列子，所以采用的中文，
然后选择自己的maven地址，这里稍微注意的是，Maven默认读取的是 .m2/setting.xml作为配置文件，
我改动了配置文件的相关下载和配置文件存储路径，所以我选用我自己的配置文件作为启动配置
然后等待下载，下载完之后，项目构建如下：
然后创建java 文件夹，作为我们存放代码的文件，并在下面创建出响应的 package 模块
最后就是这样的
——————————前期的基本准备工作到此为止，下面开始搭建环境————————————
先把最后的样子贴出来，可以先把结构搭起来，再填充内容：
1:优先配置 maven的 pom.xml 导入相关依赖

然后配置web.xml
<!-- 配置监听器加载spring -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

<!-- 配置SpringBeans的配置文件所在目录-->
<context-param>

<!-- 配置Spring的启动时机 >=0随着容器一起启动 <0第一次来请求时启动 -->

</servlet>
<servlet-mapping>

</filter-mapping>
<!--设置一个默认访问的页面-->
<welcome-file-list>
<welcome-file>/WEB-INF/index.jsp</welcome-file>
</welcome-file-list>
web.xml中指定的文件，我们按部就班的造出来
依次为：applicationContext.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"

http://www.springframework.org/schema/aop/spring-aop-3.2.xsd

http://www.springframework.org/schema/tx/spring-tx-3.2.xsd">
<!-- 配置注解扫描 -->
<context:component-scan base-package="com.test.ssm.service" />
<!-- 加载数据源所需要的参数配置文件 -->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!-- 配置 数据源 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">

<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>
<!-- 让Spring管理myBatis的会话工厂 SqlsessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean" >
<!--注入数据库连接池-->
<property name="dataSource" ref="dataSource"/>
<!--扫描Model包，使用别名-->
<property name="typeAliasesPackage" value="com.test.ssm.model"/>
<!-- 扫描sql配置文件： mapper需要的xml文件 -->
<property name="mapperLocations" value="classpath:mapper/*.xml"/>
</bean>
<!-- 配置扫描Dao接口包，动态实现Dao接口，注入到spring容器中 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!--注入Dao-->

<!--配置事务管理器-->

<property name="dataSource" ref="dataSource"/>
</bean>
<!--开启声明式事务-->
<tx:annotation-driven transaction-manager="trancationManager"/>
</beans>
其次：springmvc.xml
1 <?xml version="1.0" encoding="UTF-8"?>
2 <beans xmlns="http://www.springframework.org/schema/beans"
3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"

6 xsi:schemaLocation="http://www.springframework.org/schema/beans
7 http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
8 http://www.springframework.org/schema/mvc
9 http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
10 http://www.springframework.org/schema/context
11 http://www.springframework.org/schema/context/spring-context-3.2.xsd">
12
13 <!-- 1.配置注解扫描位置 -->
14 <context:component-scan base-package="com.test.ssm.controller" />
15
16 <!-- 2.配置注解处理映射 3.配置适配器-->
17 <mvc:annotation-driven />
18
19 <!-- 4.配置springmvc视图解析器 视图解析器解析的视频路径为：前缀 + 后缀 -->
20 <bean
21 class="org.springframework.web.servlet.view.InternalResourceViewResolver">
22 <property name="prefix" value="/WEB-INF/views" />
23 <property name="suffix" value=".jsp" />
24 </bean>
25 </beans>
然后 applicationContext.xml 又依赖新的配置文件，逐一配置出来
jdbc.properties
jdbc.driver=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8jdbc.username=rootjdbc.password=root
logback.xml
1 <?xml version="1.0" encoding="UTF-8"?>
2 <configuration debug="true">
3 <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
4 <encoder>
5 <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
6 </encoder>
7 </appender>
8 <root level="INFO">
9 <appender-ref ref="STDOUT"/>
10 </root>
11 </configuration>
运行服务器，看看效果
自动跳转到了默认的index.jsp
测试一下数据库，查询一点数据看看能否连通
发现自己都不太熟悉了，希望以后再也用不上！
