1.构建web的maven工程（具体看idea的web构建篇： idea的web构建篇 ）： 2.直接建立类，一部到位： 2.一个简单的springmvc例子： HelloContorller.java
@Controller public class HelloController { @RequestMapping("/hello") public String sayHello(){ System.out.println("hello StringMvc"); return "success"; }springmvc.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!--1.开启注解扫描，相当于把它交给ispringoc容器--> <context:component-scan base-package="cn.xiaosi.controller"></context:component-scan> <!--2.配置视图解析器解析类 @Controller public class HelloController { @RequestMapping("/hello") public String sayHello(){ System.out.println("hello StringMvc"); return "success"; } --> <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!--告诉我页面路径在哪里--> <property name="prefix" value="/WEB-INF/pages/"></property> <!--文件是以什么结尾的--> <property name="suffix" value=".jsp"></property> </bean> <!--3.开启动springmvc框架注解支持--> <mvc:annotation-driven/> </beans>web.xml
