springmvc框架搭建之xml配置说明(spring4+hibernate4)

SpringMVC框架搭建说明Spring4.1.4 + hibernate4.3.81、web.xml配置程序运行时从web.xml开始，加载顺序为：context-param -> listener -> filter ->structs (如果使用structs的话)-> servlet如下为web.xml的配置说明<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="/2001/XMLSchema-instance"xmlns="/xml/ns/javaee"xmlns:web="/xml/ns/javaee/web-app_2_5.xsd"xsi:schemaLocation="/xml/ns/javaee/xml/ns/javaee/web-app_2_5.xsd"
