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"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

<!-- 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

<!-- 注解方式 适配器、解析器加载 -->
<mvc:annotation-driven></mvc:annotation-driven>

<!-- 注解扫描制定的包路径    默认扫描com.mvc.controllter下的所有包含注解的类-->
<context:component-scan base-package="com.mvc.controller"></context:component-scan>

<!-- 视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 配置jsp路径的前缀 -->
<property name="prefix" value="/WEB-INF/jsp/"/>
<!-- 配置jsp路径的后缀 -->
<property name="suffix" value=".jsp"/>
</bean>
</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
