框架整合思路：
一、Mapper层：整合mybatis和spring
需要的jar包：
1、mybatis的jar包
2、Mysql数据库驱动
3、数据库连接池
4、Mybatis和spring的整合包。
5、Spring的jar包
配置文件：
1、mybatis的配置文件：SqlMapConfig.xml
2、Spring的配置文件：applicationContext-dao.xml
数据源
1、数据库连接池
2、配置SqlSessionFactory（mybatis和spring整合包中的）
3、配置mapper文件的扫描器。
二、Service层：
使用的jar包：spring的jar包。
配置文件：applicationContext-service.xml
配置一个包扫描器，扫描所有带@Service注解的类。
事务配置：
配置文件：applicationContext-trans.xml
1、配置一个事务管理器
2、配置tx
3、配置切面
三、表现层
使用springmvc，需要使用springmvc和spring的jar包。
配置文件：springmvc.xml
1、配置注解驱动
2、配置一个视图解析器。
3、包扫描器，@Controller注解
Web.xml
1、配置springmvc的前端控制器
2、Spring容器初始化的listener。
部分配置文件：
1/web.xml文件配置：
<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="yc" version="2.5"> <display-name>yc-manager</display-name> <!-- 初始化spring容器 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext-*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 日志配置文件 --> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>classpath:properties/log4j.properties</param-value> </context-param> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <!-- 解决post乱码 --> <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> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- springmvc的前端控制器 --> <servlet> <servlet-name>yc-manager</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- contextConfigLocation不是必须的， 如果不配置contextConfigLocation， springmvc的配置文件默认在：WEB-INF/servlet的name+"-servlet.xml" --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/springmvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>yc-manager</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!--core中的web.xml --> <context-param> <param-name>webAppRootKey</param-name> <param-value>manager.root</param-value> </context-param> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <!-- 错误页面 --> <error-page> <error-code>403</error-code> <location>/WEB-INF/jsp/403.jsp</location> </error-page> <error-page> <error-code>404</error-code> <location>/WEB-INF/jsp/404.jsp</location> </error-page> <error-page> <error-code>500</error-code> <location>/WEB-INF/jsp/500.jsp</location> </error-page> <error-page> <exception-type>java.lang.Throwable</exception-type> <location>/WEB-INF/jsp/error.jsp</location> </error-page> </web-app>
2/SqlMapConfig.xml文件配置

3/db.properties配置文件：
