2. web.xml

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>SSM项目</display-name>
  <!-- 监听到ServletContext创建后（即web容器启动）,通过xml文件创建Spring跟上下文（即Spring父容器）-->
  <context-param>

  </context-param>

    <servlet-name>dispatcherServlet</servlet-name>
    <!--拦截所有,使用REST风格 -->
    <url-pattern>/</url-pattern>
  </servlet-mapping>

</web-app>

Spring提供org.springframework.web.context.ContextLoaderListener用来监听web容器启动（即Servlet容器上下文），然后创建Spring父容器。
<context-param> 标签提供来设置Spring容器读取的xml配置文件。
Spring MVC子容器由org.springframework.web.servlet.DispatcherServlet这个Servlet在Spring 父容器的基础上构建。处理拦截分发请求。

3. Spring容器配置文件 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"
       xmlns:context="http://www.springframework.org/schema/context"
       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.xsd">

    <!-- 包扫描，将注解的类注入 -->
    <context:component-scan base-package="xyz.cglzwz.*">
        <!-- 不扫描@Controller注解 -->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!-- 载入jdbc.properties资源文件-->
    <context:property-placeholder location="classpath:jdbc.properties" ignore-unresolvable="true"/>
    <!-- 配置DBCP连接池 -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="${jdbc.driverClassName}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
        <property name="maxActive" value="${jdbc.maxActive}"/>
        <property name="maxIdle" value="${jdbc.maxIdle}"/>
        <property name="minIdle" value="${jdbc.minIdle}"/>
        <property name="maxWait" value="${jdbc.maxWait}"/>
        <property name="initialSize" value="${jdbc.initialSize}"/>
    </bean>

    <!-- 配置sqlSessionFactory(由mybatis-spring依赖包提供)-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 数据源 -->
        <property name="dataSource" ref="dataSource"/>
        <!-- mybatis全局配置文件路径 -->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
        <!-- 映射器的xml文件路径-->
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>
        <!-- 别名包扫描(扫实体类包)-->
        <property name="typeAliasesPackage" value="xyz.cglzwz.domain"/>
    </bean>

    <!-- 配置DAO层映射器接口的实现，注入容器 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- 注入SqlSessionFactory -->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <!-- 扫描的映射器接口包 -->
        <property name="basePackage" value="xyz.cglzwz.dao"/>
        <!-- 扫描添加了@Repository的接口实现 -->
        <property name="annotationClass" value="org.springframework.stereotype.Repository"/>
    </bean>
</beans>

4. Mybatis全局配置文件

<?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>
    <!-- 以下是一些全局设置，可以不配置 -->
    <settings>
        <!--使用jdbc的getGeneratekeys，插入操作返回自增主键值-->
        <setting name="useGeneratedKeys" value="true"/>
    </settings>
</configuration>

这里配置了一个插入操作返回主键的全局设置。即

@insert("INSERT INTO ...")
Integer method(...);           // 返回自增主键

5. Spring MVC配置文件 dispatcherServlet.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:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       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">

    <!-- 解决@Controller的前提配置 -->
    <mvc:annotation-driven/>
    <!-- 包扫描，将注解的类注入（扫描Controller层） -->
    <context:component-scan base-package="xyz.cglzwz.controller"/>

    <!-- JSP视图解析器 -->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <!-- 配置JSON,如使用@ResponseBody-->
    <bean id="objectMapper" class="com.fasterxml.jackson.databind.ObjectMapper"/>
</beans>
