springMvc详解

1.web.xml

<!--Spring MVC 相关配置-->
    <servlet>
        <servlet-name>controller</servlet-name>
        <servlet-class>
			org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>
                classpath:spring/spring-mvc-controller.xml
            </param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>controller</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>

    在源文件夹下新建spring文件键创建spring-mvc-controller.xml

  2.spring-mvc-controller.xml

   

<?xml version="1.0" encoding="GBK"?>
<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:util="http://www.springframework.org/schema/util" xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/context

    http://www.springframework.org/schema/util
    http://www.springframework.org/schema/util/spring-util.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

    <!-- 对项目中的所有类进行扫描以完成Bean创建并进行自动注入。  支持 @Controller、@Service 以及 @Repository 和 @Component -->
	<context:component-scan base-package="org.leopard.controller" />

    <!--
        jsp视图解析器，对模型视图名称的解析，即在模型视图名称添加前后缀
        如/view/welcome.jsp对应的视图名就是：welcome
        这个类在视图解析器链中一定要定义在其他视图的后面，因为它始终会返回一个视图
    -->
   
     <!-- 对service层下的所有类进行检测，如果发现有相关的注解，使注解生效 -->
    <context:component-scan base-package="org.leopard.service" />
    <context:component-scan base-package="org.leopard.dao" />
    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/view/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

 

3.控制层的配置

package org.leopard.controller.product;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.leopard.model.product.Product;
import org.leopard.service.product.ProductService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller //表示控制层
public class ProductController {
	
	@Autowired  //自动注入
	private ProductService productService;
	
	@RequestMapping("/product/toAddProduct.do")
	public ModelAndView toAddProduct() {
		ModelAndView view = new ModelAndView();
		view.setViewName("addProduct");
		return view;
	}
	
	
	@RequestMapping("/product/addProduct.do")
	public String addProduct(Product product, String productName, float productPrice, HttpServletRequest request, HttpServletResponse rsponse, ModelMap modelMap) {
		System.out.println(product.getProductName()+":"+product.getProductPrice()+":"+productName+":"+productPrice+":"+request.getParameter("productName"));
		productService.addProduct(product);
		return "redirect:/product/productList.do";
	}
	
	@RequestMapping("/product/productList.do")
	public ModelAndView productList(ModelMap modelMap) {
		ModelAndView modelAndView = new ModelAndView();
		modelAndView.addObject("userName", "yuxy");
		modelMap.put("userAge", 10);
		modelAndView.setViewName("productList");
		modelAndView.addObject(modelMap);
		return modelAndView;
	}
}
