spring4.1.3+springmvc+mybatis3.2.1整合
注意：这里使用了mybatis3.2.1版本，刚开始用了3.4.1的版本，会报一个很奇怪的错(java.lang.AbstractMethodError: org.mybatis.spring.transaction.SpringManagedTransaction.getTimeout()Ljava/lang/Integer;)，换了这个包就好了
-
所需包，spring的jar包，mybatis的jar包，spring-mybatis.jar，数据库连接的mysql-connection.jar，日志的log4j.jar（33个包，如果用到了jstl还需要加入jstl包，36个）
-
在web.xml中添加spring的监听，以及配置springmvc的核心文件。
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<display-name></display-name>
<!-- spring文件的监听 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- spring 加载配置文件的路径 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:beans.xml</param-value>
</context-param>
<!-- 配置springmvc核心控制器 -->
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 加个过滤器，让所有请求页面的编码方式都为utf-8 -->
<filter>
<filter-name>CharEncodingFilter</filter-name>
<filter-class>com.sram.filter.CharEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharEncodingFilter</filter-name>
<!-- /*表示所有的请求都过滤 -->
<url-pattern>/*</url-pattern>
</filter-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
至此，web.xml文件配置结束
- 在WEB-INF目录添加spring-servlet.xml（ps:web.xml中配置的servlet核心名字叫spring，它就会去找叫spring-servlet.xml的springmvc配置文件）
配置如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"

<property name="prefix" value="/WEB-INF/jsp/"/>

</beans>
- 在src目录下添加spring的配置文件，beans.xml，内容如下：
