SpringMvc入门二----HelloWorld

1. 导入需要的架包：

2. 配置web.xml,添加Servlet

<servlet>

<servlet-name>springmvc</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:spring-mvc.xml</param-value>

</init-param>

</servlet>

<servlet-mapping>

<servlet-name>springmvc</servlet-name>

<url-pattern>*.do</url-pattern>

</servlet-mapping>

3. 添加spring-mvc.xml文件

<?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"

xsi:schemaLocation="

http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context.xsd">

<!-- 使用注解的包，包括子集 -->

<context:component-scan base-package="com.java1234"/>

<!-- 视图解析器 -->

<bean id="viewResolver"

class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<property name="prefix" value="/WEB-INF/jsp/" />

<property name="suffix" value=".jsp"></property>

</bean>

</beans>

4. 在index.jsp中添加如下代码：

<body>

<a href="helloWorld.do">Hello World SpringMvc</a>

</body>

5. 在/WEB-INF/下新建一个jsp文件，在jsp文件夹下建立一个helloword.jsp文件

<%@ page language="java" contentType="text/html; charset=UTF-8"

pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>Insert title here</title>

</head>

<body>

${message }

</body>

</html>

6. 编写Controller类HelloWorldController.java：

@Controller

public class HelloWorldController {

@RequestMapping("/helloWorld")

public String helloWorld(Model model){

model.addAttribute("message", "StringMvc大爷你好！");

return "helloWorld";

}

}
