(1)创建一个maven得web工程
(2)引入springmvc的依赖
1 <dependencies> 2 <dependency> 3 <groupId>org.springframework</groupId> 4 <artifactId>spring-webmvc</artifactId> 5 <version>5.3.4</version> 6 </dependency> 7 </dependencies>
(3) springmvc得配置文件
<?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:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd"> <!--包扫码 controller中类--> <context:component-scan base-package="com.ykq.controller"/> <!--视图解析器 prefix=前缀 /views/ suffix=后缀 .jsp --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/views/"/> <property name="suffix" value=".jsp"/> </bean> </beans>
(4)创建一个控制类
@Controller //表示该类为控制层类。 public class HelloController { @RequestMapping("/hello") public ModelAndView hello(){ System.out.println("hello方法被调用了"); ModelAndView mv=new ModelAndView("hello"); return mv; } }
(5) 在web.xml文件加载springmvc得配置文件
<servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.dispatcherServlet</servlet-class> <!--指定springmvc得配置文件的路径--> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
(6)测试 http://localhost:8080/项目名/资源
