Spring MVC 编程流程步骤

1. 建立Maven工程

2. 添加Spring MVC依赖

  <dependencies>
  <dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-webmvc</artifactId>
  <version>4.3.9.RELEASE</version>
  </dependency>
  </dependencies>

3. 新建核心配置文件,并在核心配置文件里配置

  配置组件扫描:

  <context:component-scan base-package="com.jt"/>

  启用MVC默认配置(@RequestMapping):

  <mvc:annotation-driven/>

配置视图解析器

  <bean  id="viewResolver"   class="org.springframework.web.servlet.view.InternalResourceViewResolver">

   <property name="prefix" value="/WEB-INF/pages/"/>

    <property name="suffix" value=".jsp"/>

  </bean>

4. 配置Spring MVC前段控制器(在web.xml文件中配置)地

  <servlet>

  <servlet-name>dispatcherServlet</servlet-name>

  <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class>

  <init-param>

  <param-name>contextConfigLocation</param-name>

  <param-value>classpath:spring-configs.xml</param-value>

  </init-param>

  <load-on-startup>1</load-on-startup>

  </servlet>

  <servlet-mapping>

  <servlet-name>dispatcherServlet</servlet-name>

  <url-pattern>*.do</url-pattern>

  </servlet-mapping>

5. 创建并配置Spring MVC 后端控制器

6. 部署及测试spring mvc 项目应用
