spring 框架的配置文件

首先要导入需要的jar包配置web.xml:

<!-- Spring MVC配置 -->
<!-- ====================================== -->
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 可以自定义servlet.xml配置文件的位置和名称，默认为WEB-INF目录下，名称为[<servlet-name>]-servlet.xml，如spring-servlet.xml
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-servlet.xml</param-value>  默认
</init-param>
-->
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>*.jsp</url-pattern>

<!-- <url-pattern>/</url-pattern> -->

</servlet-mapping><!-- Spring配置 --><!-- ====================================== -->

<listener><listenerclass>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 指定Spring Bean的配置文件所在目录。默认配置在WEB-INF目录下 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:config/applicationContext.xml</param-value></context-param>

配置spring-servlet.xml(spring-servlet这个名字是因为上面web.xml中<servlet-name>标签配的值为spring（<servlet-name>spring</servlet-name>），再加上“-servlet”后缀而形成的spring-servlet.xml文件名，如果改为springMVC，对应的文件名则为springMVC-servlet.xml)：

<?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 <a href="http://www.springframework.org/schema/context/spring-context-3.0.xsd">http://www.springframework.org/schema/context/spring-context-3.0.xsd</a>"><!-- 启用spring mvc 注解 --><context:annotation-config /><!-- 设置使用注解的类所在的jar包 --><context:component-scan base-package="controller"></context:component-scan><!-- 完成请求和注解POJO的映射 --><bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />　　<!-- 对转向页面的路径解析。prefix：前缀， suffix：后缀 --><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/jsp/" p:suffix=".jsp" /></beans>
