springMVC第一天

这些是springMVC3.2所用到的jar包

web.xml配置

<?xml version="1.0" encoding="UTF-8"?>

  <!-- springmvc前端控制器 -->
  <servlet>
  	<servlet-name>springmvc</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  	<!-- contextConfigLocation配置springmvc加载的配置文件（配置处理器映射器、适配器等等）
  	如果不配置contextConfigLocation，默认加载的是/WEB-INF/servlet名称-serlvet.xml（springmvc-servlet.xml）
  	 -->
  	<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>*.action</url-pattern>
  </servlet-mapping>
  
  
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

上面我讲配置文件放在classpath下面，在项目件文件夹的时候要注意要选择新建source folder；如果新建文件夹的时候选择的是folder在调用url的时候就会提示找不到配置文件(找不到springmvc.xml)

　springmvc.xml

</beans>

　controllter代码，没有查数据

package com.mvc.controller;

import java.util.ArrayList;
import java.util.Date;
import java.util.List;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.mvc.model.Items;

/***商品控制器*/
@Controller
@RequestMapping("/itemsController")
public class ItemsController {

	@RequestMapping("/queryItems")
	public ModelAndView queryItems(){
		
		List<Items> items=new ArrayList<Items>();
		
		Items items_1 = new Items();
		items_1.setName("小米note");
		items_1.setPrice(6000f);
		items_1.setDetail("ThinkPad");
		items_1.setCreatetime(new Date());
		
		Items items_2 = new Items();
		items_2.setName("荣耀华为plus");
		items_2.setPrice(5000f);
		items_2.setDetail("荣耀华为plus");
		items_2.setCreatetime(new Date());
		
		items.add(items_1);
		items.add(items_2);
		
		ModelAndView modelAndView=new ModelAndView();
		modelAndView.addObject("items", items);
		modelAndView.setViewName("items/itemsList");
		
		return modelAndView;
	}
}

　　前面springmvc.xml中将视图解析器的路径配置在/WEB-INF/jsp/下,文件名后缀为.jsp，所以对应的jsp路径就是/WEB-INF/jsp/items/itemsList.jsp
