spring+mybatis+springmvc的配置

1.web.xml的配置

<?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">
    
    <!-- 上下文參數（第一啓動），指定jdbc配置文件位置  -->
    <context-param>
        <param-name>contextConfigLocation</param-name>  
        <param-value>classpath:/config/jdbc.xml</param-value>  
      </context-param>     
     
    <!-- spring監聽器（第二啓動），監聽springMvc環境 -->
    <listener>  
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
    </listener>  
    
    <!-- springMvc編碼攔截器（第三啓動），springMvc內置的編碼攔截器 -->
    <filter>  
        <filter-name>encodingFilter</filter-name>  
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>  
    </filter>  
     
    <filter-mapping>  
        <filter-name>encodingFilter</filter-name>  
        <url-pattern>/*</url-pattern>  
    </filter-mapping>
      
      <!-- springMvc前置總控制器（第四啓動），在分發其它的控制器前都要通過這個總控制器 -->
    <servlet>  
        <servlet-name>spring-mvc</servlet-name>  
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
    <init-param>  
        <param-name>contextConfigLocation</param-name>  
        <param-value>classpath:/config/springmvc.xml</param-value>  
    </init-param>  
    <load-on-startup>2</load-on-startup>  
    </servlet>  
     
    <servlet-mapping>  
        <servlet-name>spring-mvc</servlet-name>  
        <url-pattern>*.do</url-pattern>  
    </servlet-mapping>  
    
    <!-- 網站的默認首頁   -->
    <welcome-file-list>
        <welcome-file>begin.jsp</welcome-file>
    </welcome-file-list>
</web-app>

2.spring 的配置文件applicationContext-mybatis.xml

    <!-- 啓動時掃描全部的controller -->
    <context:component-scan base-package="com.springmvc.web" />
    
    <!--  主要做用於@Controller，激活該模式，下面是一種簡寫形式，徹底能夠手動配置替代這種簡寫形式，它會自動註冊DefaultAnnotationHandlerMapping與AnnotationMethodHandlerAdapter，是spring MVC爲@Controllers分發請求所必須的   -->
    <mvc:annotation-driven />
    
    <!-- 配置js,css等靜態文件直接映射到對應的文件夾，不被DispatcherServlet處理 -->
    <mvc:resources location="/WEB-INF/resources/**" mapping="/resources" />
    
    <!-- jsp頁面解析器，當Controller返回XXX字符串時，先經過攔截器，而後該類就會在/WEB-INF/views/目錄下，查找XXX.jsp文件 -->
