SpringMVC 配置

时间:2022-08-18 09:27:00

1、在WEB-INF\web.xml中定义前端控制器

<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.xml</param-value>

  </init-param>

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

</servlet>

<servlet-mapping>

  <servlet-name>springmvc</servlet-name>

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

</servlet-mapping>

2、在springmvc配置文件中定义

  1)配置处理器适配器 

    <bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/>

  2)配置处理器映射器

    <!-- 根据bean的name进行查找Handler 将action的url配置在bean的name中 -->

    <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" />

  3)处理器开发

public class ItemList1 implements Controller {

    @Override
    public ModelAndView handleRequest(HttpServletRequest request,
            HttpServletResponse response) throws Exception {

        //商品列表
        List<Items> itemsList = new ArrayList<Items>();

        Items items_1 = new Items();
        items_1.setName("联想笔记本");
        items_1.setPrice(6000f);
        items_1.setDetail("ThinkPad T430 联想笔记本电脑!");

        Items items_2 = new Items();
        items_2.setName("苹果手机");
        items_2.setPrice(5000f);
        items_2.setDetail("iphone6苹果手机!");

        itemsList.add(items_1);
        itemsList.add(items_2);

        //创建modelAndView准备填充数据、设置视图
        ModelAndView modelAndView = new ModelAndView();

        //填充数据
        modelAndView.addObject("itemsList", itemsList);
        //视图
        modelAndView.setViewName("order/itemsList");

        return modelAndView;
    }

}

  

  4)处理器配置

    <!-- controller配置 -->

    <bean name="/items1.action" id="itemList1" class="cn.itcast.springmvc.controller.first.ItemList1"/>

  5)配置视图解析器   

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

    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>

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

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

  </bean>
