springMvc 通过url传值，实现访问
springMvc 通过url传值，实现访问
1、创建web项目，引入相关jar包，并完成相应配置，在上一篇博客已经实现
2、在WEB-INF下创建jsp文件夹，并创建hello.jsp文件
1 <%@ page language="java" contentType="text/html; charset=UTF-8" 2 pageEncoding="UTF-8"%> 3 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 4 <html> 5 <head> 6 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 7 <title>Hello</title> 8 </head> 9 <body> 10 你好，${name }! 11 12 </body> 13 </html>
3、在与web.xml同目录下创建mvcdemo-servlet.xml文件
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:mvc="http://www.springframework.org/schema/mvc" 5 xmlns:context="http://www.springframework.org/schema/context" 6 xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd 7 http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd 8 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd"> 9 <!-- 包扫描 --> 10 <context:component-scan base-package="com.GetcharZp.mvcdemo" /> 11 12 <!-- mvc注解驱动 --> 13 <mvc:annotation-driven /> 14 15 <!-- 视图解析器 ，支持多种视图 --> 16 <bean 17 class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"> 18 <property name="viewResolvers"> 19 <list> 20 <bean 21 class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 22 <property name="viewClass" 23 value="org.springframework.web.servlet.view.JstlView" /> 24 <property name="prefix" value="/WEB-INF/jsp/" /> 25 <property name="suffix" value=".jsp" /> 26 </bean> 27 <bean 28 class="org.springframework.web.servlet.view.BeanNameViewResolver" /> 29 </list> 30 </property> 31 <property name="defaultViews"> 32 <list> 33 <bean 34 class="org.springframework.web.servlet.view.json.MappingJackson2JsonView"></bean> 35 </list> 36 </property> 37 </bean> 38 39 </beans>
4、创建com.GetcharZp.mvcdemo包，并在其下创建HelloController.java代码
1 package com.GetcharZp.mvcdemo; 2 3 import org.springframework.stereotype.Controller; 4 import org.springframework.ui.ModelMap; 5 import org.springframework.web.bind.annotation.RequestMapping; 6 7 @Controller 8 public class HelloController { 9 10 @RequestMapping(value="h") 11 public String hellog(String name, ModelMap mm){ 12 mm.addAttribute("name", name); 13 return "hello"; 14 } 15 }
5、web.xml进行如下配置
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 3 xmlns="http://xmlns.jcp.org/xml/ns/javaee" 4 xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" 5 version="3.1"> 6 <display-name>mvcdemo</display-name> 7 8 <!-- 启动监听 --> 9 <listener> 10 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 11 </listener> 12 13 <!-- 分发的Servlet --> 14 <servlet> 15 <servlet-name>mvcdemo</servlet-name> 16 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 17 </servlet> 18 <servlet-mapping> 19 <servlet-name>mvcdemo</servlet-name> 20 <url-pattern>/</url-pattern> 21 </servlet-mapping> 22 <!-- 强制将根容器的配置指向mvc的容器 --> 23 <context-param> 24 <param-name>contextConfigLocation</param-name> 25 <param-value>/WEB-INF/mvcdemo-servlet.xml</param-value> 26 </context-param> 27 <!-- 字符编码集过滤器 --> 28 <filter> 29 <filter-name>characterEncodingFilter</filter-name> 30 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> 31 <init-param> 32 <param-name>encoding</param-name> 33 <param-value>UTF-8</param-value> 34 </init-param> 35 <init-param> 36 <param-name>forceEncoding</param-name> 37 <param-value>true</param-value> 38 </init-param> 39 </filter> 40 <filter-mapping> 41 <filter-name>characterEncodingFilter</filter-name> 42 <url-pattern>/*</url-pattern> 43 </filter-mapping> 44 45 </web-app>
