首先说明一下Web.xml中配置项的执行过程: <context-param> <listenser> <filter> <servlet>
首先初始化Spring的bean工厂,通过加载beans.xml初始化,其次通过spring的listener来监听,再次当请求时拦截并编码为UTF-8,最后由DispatcherServlet处理并分发到controller上

一、 项目结构图如下:
此项目主要目的是在于集成,主要包括一下步骤:

二、具体的详细步骤如下:
1. Jar包的加入,包括:spring、MyBatis、log、spring-mybatis、oracle。具体的jar包如下图所示,并简要的说明每个jar的作用。
2. 需要在Web.xml文件中配置每个框架的入口。如下所示:
- <?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">
- <display-name>ssm</display-name>
- <!-- 初始化spring的配置文件 -->
- <context-param>
- <param-name>contextConfigLocation</param-name>
- <param-value>classpath*:conf/beans.xml</param-value>
- </context-param>
- <listener>
- <description>spring监听器</description>
- <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
- </listener>
- <!-- 配置springmvc的入口 -->
- <servlet>
- <servlet-name>action</servlet-name>
- <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
- <init-param>
- <param-name>contextConfigLocation</param-name>
- <param-value>classpath*:conf/spring-mvc.xml</param-value>
- </init-param>
- <load-on-startup>1</load-on-startup>
- </servlet>
- <servlet-mapping>
- <servlet-name>action</servlet-name>
- <url-pattern>/</url-pattern>
- </servlet-mapping>
- <!—springMVC配置结束 -->
- <!-- 拦截器,对每个请求处理字符编码为UTF-8 -->
- <filter>
- <filter-name>encodingFilter</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>
- </filter>
- <filter-mapping>
- <filter-name>encodingFilter</filter-name>
- <url-pattern>/</url-pattern>
- </filter-mapping>
- <!-- 拦截器结束-->
- </web-app>

3. springMVC的配置文件
