<!-- 自动扫描包，让指定包下的注解生效,由ioc容器统一管理 --> <context:component-scan base-package="controller"/> <!-- 1加载注解驱动 --><mvc:annotation-driven/> <!-- 2静态资源过滤 --><mvc:default-servlet-handler/><!-- 3视图解析器 --><bean id="internalresourceviewresolver" class= "org.springframework.web.servlet.view.internalresourceviewresolver"><property name="prefix" value="/web-inf/jsp/"/><property name="suffix" value=".jsp"/></bean> |
3、controller层

package controller;@controllerpublic class hellocontroller {@requestmapping("/hello")public string hello(model model){ // model 封装数据 model.addattribute("msg","hello my first spring mvc project"); // 返回的字符串就是视图的名字 会被视图解析器处理 return "hello"; }} |
4、jsp
在jsp包下新建hello.jsp

<%@ page contenttype="text/html;charset=utf-8" language="java" %> <html> <head><title>title</title> </head> <body>${msg} </body> </html> |
三、web.xml
1、配置前端控制器
|

<!-- 配置初始化参数 --><init-param><param-name>contextconfiglocation</param-name><param-value>classpath:applicationcontext.xml</param-value></init-param> |
3、设置启动级别
|

<!-- 设置启动级别 --><load-on-startup>1</load-on-startup></servlet> |
4、设置springmvc拦截请求
|

6、运行web
打包
file→project structure
删除默认的包
点ok→ok
