由于公司的项目转型，以后基本都要使用java了，10年的c#生涯要告一段落了。
今天是学习java的第2天，根据所学知识，自己做了第一个springmvc demo。
一。创建springmvc 工程
file=》new=》other=》web=》dynamic web project
二。添加相应的jar包
spring mvc 下载jar包地址https://repo.spring.io/libs-release-local/org/springframework/spring/4.3.4.RELEASE/spring-framework-4.3.4.RELEASE-dist.zip
commons-logging 下载地址 https://mirrors.tuna.tsinghua.edu.cn/apache//commons/logging/binaries/commons-logging-1.2-bin.zip
jstl 下载地址http://repo2.maven.org/maven2/javax/servlet/jstl/1.2/jstl-1.2.jar
三。添加controller
package springmvcfirest;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class hellozw {
@RequestMapping("/hellozw1")
public String hellozw1(Model model)
{
model.addAttribute("msg","hello sprinhellozwgmvcfirest!");
return "hellozw";
}
}
四，添加jsp文件
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<div>
${msg}</div>
</body>
</html>
五。添加 springmvcfirest-servlet.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.2.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd
http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task-4.2.xsd">
<!-- 自动扫描组件 -->
<context:component-scan base-package="springmvcfirest" />
<!-- 打开注解驱动 -->
<mvc:annotation-driven />
<!-- 配置jsp视图解析器 ，需要有jstl这个jar包，否则不能映射 -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/pages/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
六。修改web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
id="WebApp_ID" version="4.0">
<display-name>springmvcfirest</display-name>
<servlet>
<servlet-name>springmvcfirest</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvcfirest</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>/WEB-INF/pages/Hello2.jsp</welcome-file>
</welcome-file-list>
</web-app>
7运行效果
ok，第一个springmvc项目就弄好啦
