（1）新建一个maven项目叫做ssmcurd
（2）web.xml里面要导入相关jar包：
<project xmlns="http://maven.apache.org/POM/4.0.0"

（3）在resource下创建一个数据库配置文件dbconfig.properties：
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/ssm_curd?useUnicode=true&characterEncoding=UTF-8
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.user=root
jdbc.password=1234567890
（4）在resource下创建一个applicationContext.xml，配置spring：
<?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: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-4.3.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">
<!-- spring的配置文件，这里主要配置和业务逻辑有关的 ,比如数据源，事务控制，配置和mybatis的整合（mybatis配置文件的位置，mapper.xml位置，dao接口实现的位置，批量操作SqlSession）-->
<!-- 核心点：数据源，与mybatis的整合，事务控制 -->
<!-- 注解扫描 -->
<context:component-scan base-package="hua" >
<!-- 不扫控制器的-->
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!-- 引入外部文件 ,需要namespaces加个context-->
<context:property-placeholder location="classpath:dbconfig.properties"/>
<bean id="pooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
<property name="driverClass" value="${jdbc.driverClass}"></property>
<property name="user" value="${jdbc.user}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>
<!-- 配置和mybatis的整合 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 指定mybatis全局配置文件的位置 -->
<property name="configLocation" value="classpath:mybatis-config.xml"></property>
<property name="dataSource" ref="pooledDataSource"></property>
<!-- 指定mybatis、mapper文件的位置 -->
<property name="mapperLocations" value="classpath:mapper/*.xml"></property>
</bean>
<!-- 配置扫描器，将mybatis接口的实现加入到ioc容器中。因为mybatis接口的实现是一个代理对象 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 扫描所有的dao接口的实现，加入到ioc容器中 -->
<property name="basePackage" value="hua.dao"></property>
</bean>
<!-- 配置一个可以执行批量的SqlSession -->
<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate" >
<constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory"></constructor-arg>
<constructor-arg name="executorType" value="BATCH"></constructor-arg>
</bean>
<!-- 事物控制配置 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!-- 控制数据源 -->
<property name="dataSource" ref="pooledDataSource"></property>
</bean>
<!-- 开启基于注解的事务，使用xml配置形式的事务，（推荐比较重要的都是使用配置式） -->
<aop:config>
<!-- 切入点表达式 service下的所有类的所有方法都想来控制事务-->
<aop:pointcut expression="execution(* hua.service..*())" id="txPoint"/>
<!-- 配置事务增强：事务如何切入规则指定，切入方法指定-->
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPoint"/>
</aop:config>
<!-- 配置事务增强，也就是配置事务如何切入 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<!-- 这个切入点切入的所有方法都是事务方法 -->
<tx:method name="*"/>
<!-- 以get开始的所有方法都是查询 -->
<tx:method name="get*" read-only="true"/>
</tx:attributes>
</tx:advice>
</beans>
（5）在resource下创建一个mybatis-config.xml文件，配置mybatis
<?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>
<typeAliases>
<package name="hua.bean"/>
</typeAliases>
<!-- 在 MyBatis 的xml 中配置拦截器插件 -->
<plugins>
<!-- com.github.pagehelper为PageHelper类所在包名 -->
<plugin interceptor="com.github.pagehelper.PageInterceptor">
<!-- 分页参数合理化 -->
<property name="reasonable" value="true"/>
</plugin>
</plugins>
</configuration>
（6）在WEB—INF下面创建dispatcherServlet-servlet.xml，配置springmvc
<?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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
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-4.3.xsd">
<!-- springmvc的配置文件、包含网站的跳转逻辑的控制、配置 -->
<!-- 注解扫描 -->
<context:component-scan base-package="hua" use-default-filters="false">
<!-- 只扫描控制器 ,所有标了控制器注解的就是控制器，只扫这些-->
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!-- 配置视图解析器。方便页面返回 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<!-- 两个标准配置 -->
<!-- 将springmvc不能处理的请求交给tomcat，实现动态静态资源都能访问成功 -->
<mvc:default-servlet-handler/>
<!-- 能支持springmvc更高级的一些功能，比如基于jsr303的校验，快捷的ajax请求，更重要的是映射动态请求 -->
<mvc:annotation-driven/>
</beans>
（7）在web.xml配置
<?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_2_5.xsd" id="WebApp_ID" version="2.5">
<!-- 1、启动Spring的容器 -->
<!-- needed for ContextLoaderListener -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- Bootstraps the root web application context before servlet initialization -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 2、springmvc的前端控制器，拦截所有请求 -->
<!-- The front controller of this Spring Web application, responsible for handling all application requests -->
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- Map all requests to the DispatcherServlet for handling -->
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 3、字符编码过滤器,拦截所有请求,一定要在所有过滤器之前 -->
<filter>
<filter-name>CharacterEncodingFilter</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>forceRequestEncoding</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>forceResponseEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
（8）项目结构如下：
补充：
<%
pageContext.setAttribute("Pro_Path", request.getContextPath());
%>
<!-- 注意：web路径：
不以/开始的相对路径，找资源，以当前资源的路径为基准，经常容易出问题
以/开始的相对路径，找资源，以服务器的路径为标准(http://localhost:3306/)，然后再加上项目名才能找到
-->
<script src="${Pro_Path }/static/jquery/jquery-2.0.3.min.js"></script>
