springmvc的注解开发

1. 配置DispatcherServlet

   <servlet>
       <servlet-name>springmvc</servlet-name>
       <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
       <init-param>
           <param-name>contextConfigLocation</param-name>
           <param-value>classpath:springmvc-servlet.xml</param-value>
       </init-param>
       <load-on-startup>1</load-on-startup>
   </servlet>
   <servlet-mapping>
       <servlet-name>springmvc</servlet-name>
       <url-pattern>/</url-pattern>
   </servlet-mapping>

2. spring配置文件springmvc-servlet.xml

   <?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"
          xmlns:mvc="http://www.springframework.org/schema/mvc"
          xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context.xsd
           http://www.springframework.org/schema/mvc
           http://www.springframework.org/schema/mvc/spring-mvc.xsd">
   
       <!--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="cn.pinked.controller"/>
       <!--过滤默认的静态资源-->
       <mvc:default-servlet-handler/>
       <!--注解驱动-->
       <mvc:annotation-driven/>
       <!--视图解析器-->
       <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="internalResourceViewResolver">
           <property name="prefix" value="/WEB-INF/jsp/"/>
           <property name="suffix" value=".jsp"/>
       </bean>
   
   </beans>

3. 控制器

   @Controller
   public class HelloController {
       //真实路径
       @RequestMapping("/hello")
       public String hello(Model model) {
           //封装数据
           model.addAttribute("msg", "hello springmvc annotation");
           //返回给视图解析器拼接
           return "hello";
       }
   
   }

4. hello.jsp
