        <context:exclude-filter type="annotation"
            expression="org.springframework.stereotype.Controller" />
    </context:component-scan>
</beans>

spring mvc配置文件内容如下:

<?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:p="http://www.springframework.org/schema/p"

    xsi:schemaLocation="http://www.springframework.org/schema/beans

           http://www.springframework.org/schema/aop/spring-aop.xsd  
           http://www.springframework.org/schema/tx  
           http://www.springframework.org/schema/tx/spring-tx.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
           http://www.springframework.org/schema/cache 
           http://www.springframework.org/schema/cache/spring-cache.xsd">

    <context:component-scan base-package="com.kou.controller" />

    <mvc:default-servlet-handler />
    <mvc:annotation-driven />

</beans>

applicationContext.xml文件内容主要是spring的通用配置，例如数据源、事务管理、与mybatis的整合等等，需要注意的是，这里配置扫描的包不包括controller类的包，扫描controller注解类的配置应该放在spring mvc配置文件中，这里涉及到父容器、子容器的问题，不深入研究，能配置成功就好。

springmvc.xml文件内容主要是spring mvc一些特殊的配置，详见另一篇spring mvc。

其实，也可以把这两个配置文件合并为一个，合并和分开各有优缺点。合并之后，只需维护一个配置文件，这是优点，缺点是各种配置糅合在一起，不好看。

需要注意的是，mybatis整合spring后就不需要写映射文件了，只需要applicationContext.xml文件中mybatis相关的那2块配置就可以了。

web.xml文件内容:

<!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>
    <context-param>
        <!-- 参数名必须是contextConfigLocation -->
        <param-name>contextConfigLocation</param-name>
        <!-- 参数值是配置文件的名字 -->
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <filter>
        <filter-name>springCharacterEncodingFilter</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>springCharacterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

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

    <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.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet>
        <servlet-name>DruidStatView</servlet-name>
        <description>druid连接池监控</description>
        <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>DispatcherServlet</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>DruidStatView</servlet-name>
        <url-pattern>/druid/*</url-pattern>
    </servlet-mapping>
    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>
</web-app>

ContextLoaderListener监听器的contextConfigLocation属性是applicationContext.xml文件路径，DispatcherServlet的contextConfigLocation属性是springmvc.xml文件路径。

log4j.properties文件内容:

log4j.rootLogger=INFO,Console,File  
#定义日志输出目的地为控制台  
log4j.appender.Console=org.apache.log4j.ConsoleAppender
#可以灵活地指定日志输出格式，下面一行是指定具体的格式  
log4j.appender.Console.layout = org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n
  
#每天生成一个新的文件  
log4j.appender.File = org.apache.log4j.DailyRollingFileAppender  
#指定输出目录  
log4j.appender.File.File = /logs/root.log  
log4j.appender.File.layout = org.apache.log4j.PatternLayout  
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

log4j.properties文件放在classpath下，只需要有log4j-1.2.*.jar(如果使用slf4j的话，还需要slf4j-api-***.jar、slf4j-log4j12-***.jar)，不需要额外配置或者额外代码就可以在类中通过Logger.getLogger(class clazz)的方式生成logger对象，进而调用其info(Object obj)方法在log4j.properties配置的日志文件中输出日志。
