关于spring+springMVC+myBatis的一些基础配置以及整合

不说了多了   直接上代码  首先是从程序的入口开始说：

 web.xml

 <?xml version="1.0" encoding="UTF-8"?>  <web-app version="2.4"   xmlns="http://java.sun.com/xml/ns/j2ee"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">    <welcome-file-list>      <welcome-file>index.jsp</welcome-file>    </welcome-file-list>        <!--    设置session过期的时间    -->    <session-config>    <session-timeout>20</session-timeout>    </session-config>        <!--    读取spring的配置文件    -->   <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>classpath:config/spring.xml;classpath:config/spring-myBatis.xml</param-value>    </context-param>        <listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>         <listener>      <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>    </listener>      <!--    设置字符编码，将所有的字符编码同意设置为utf-8    -->    <filter>    <filter-name>filterEncoding</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>filterEncoding</filter-name>    <url-pattern>/</url-pattern>    </filter-mapping>        <!--    生成一次性验证码的servlet    -->    <servlet>    <servlet-name>verifyCode</servlet-name>    <servlet-class>com.longhang.tool.verifyCode.VerifyCodeServlet</servlet-class>    </servlet>        <!--    将所有*.do的请求交给springMVC的DispatcherServlet来处理    -->    <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:config/springMVC-config.xml</param-value>    </init-param>    <load-on-startup>1</load-on-startup>    </servlet>        <servlet-mapping>    <servlet-name>verifyCode</servlet-name>    <url-pattern>/verifyCode</url-pattern>    </servlet-mapping>        <servlet-mapping>    <servlet-name>DispatcherServlet</servlet-name>    <url-pattern>*.do</url-pattern>    </servlet-mapping>  </web-app>

springMVC的配置文件

<?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"                   xmlns:context="http://www.springframework.org/schema/context"              xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd                http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd                http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd                http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">        <!--    配置自动扫描的包，让其扫描    com.longhang,controller下面的所有包   -->        <context:component-scan base-package = "com.longhang.controller"></context:component-scan>       <!--      配置视图解析器    将视图逻辑名解析为/*.jsp   -->    <bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver">    <property name = "prefix" value = "/"></property>    <property name = "suffix" value = ".jsp"></property>    </bean>    </beans>

spring.xml的配置

<?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:context="http://www.springframework.org/schema/context" xsi:schemaLocation="  http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans-3.0.xsd  http://www.springframework.org/schema/context  http://www.springframework.org/schema/context/spring-context-3.0.xsd  ">  <context:property-placeholder location="classpath:config/druid.properties" />  <!-- 自动扫描(自动注入) -->  <context:component-scan base-package = "com.longhang.service"></context:component-scan>      </beans>
