环境:1、基于spring4.2.4版本,也是spring当前(2016.2)最新的GA版本
2、maven 3.2.1
3、jdk1.7
xml配置1:
web.xml
<?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_3_0.xsd"
id="WebApp_ID" version="3.0"> <display-name>SpringMVC</display-name> <!-- Spring配置;MyBatis配置 -->

</context-param> <listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener> <!-- Spring MVC配置 -->
<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:spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet> <servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping> </web-app>
xml配置2:spring与springMVC的配置文件没有放在默认的WEB-INF下面,而是放在src/main/resources下面
spring.xml 主要作用就是扫描非controller的bean,同时也可以承担引入外部属性文件,比喻mybatis的属性文件(连接字符串)
<?xml version="1.0" encoding="UTF-8"?>
