写配置

web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
         xmlns="http://java.sun.com/xml/ns/j2ee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

  <!--配置Spring容器启动-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <!--指定spring配置文件位置-->
    <param-value>classpath:Spring/applicationContext.xml</param-value>
  </context-param>

  <!--配置监听器-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!--配置springmvc的前端控制器-->
  <servlet>
    <servlet-name>DispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:SpringMVC/springmvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>DispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <!--两个标准配置-->
  <!--字符编码-->
  <!--配置一个字符编码的Filter-->
  <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>forceEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

  <!--支持REST风格的filter-->
  <filter>
    <filter-name>HiddenHttpMethodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>HiddenHttpMethodFilter</filter-name>
    <!--拦截所有请求-->
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

SpringMVC的配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       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
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <!--SpringMVC只扫描控制器:禁用默认过滤规则-->
    <context:component-scan base-package="Com" use-default-filters="false">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    <!--视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/pages/"></property>
    <property name="suffix" value=".jsp"></property>
</bean>

    <!--文件上传解析器: id必须是multipartFile-->
    <bean  id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!--设置文件上传最大量为5m-->
        <property name="maxUploadSize" value="5242880"></property><!--spel运算符，计算最大可上传文件体积-->
        <!--设置默认的编码-->
        <property name="defaultEncoding" value="utf-8"></property>
    </bean>

    <!--扫描静态资源-->
    <mvc:default-servlet-handler/>
    <!--扫描动态资源-->
    <mvc:annotation-driven/>
</beans>

整合步骤

1.导入整合包，将dao的实现加入到容器中

   <!--mybaits和spring整合包的依赖-->
      <dependency>
          <groupId>org.mybatis</groupId>
          <artifactId>mybatis-spring</artifactId>
          <version>1.3.2</version>
      </dependency>

MyBaits与Spring整合的关键配置

      <!--配置使用Mybaits操作数据库-->
<!--可以根据配置文件得到SqlSessionFactory-->
<bean id="sqlSessionFactoryBean" class="org.mybatis.s以上是关于SSM整合的主要内容，如果未能解决你的问题，请参考以下文章
