怎么创建一个Spring MVC项目？-优快云博客

本文详细介绍了如何使用Maven创建JavaWeb项目，并配置SpringMVC依赖，通过编写控制器和视图实现基本功能。具体步骤包括创建项目、配置SpringMVC依赖、配置web.xml文件、编写控制器和视图类，最终部署并运行。

1、首先创建一个Java Web项目

2、配置Spring MVC依赖的jar包

在pom.xml中增加如下内容

<properties>
		<spring.version>3.0.5.RELEASE</spring.version>
	</properties>
 
	<dependencies>
 
		<!-- Spring 3 dependencies -->
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-core</artifactId>
			<version>${spring.version}</version>
		</dependency>
 
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-web</artifactId>
			<version>${spring.version}</version>
		</dependency>
 
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-webmvc</artifactId>
			<version>${spring.version}</version>
		</dependency>
 
	</dependencies>

3、配置web. xml，使Spring MVC起作用

web.xml配置为

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

	<display-name>Spring MVC Application</display-name>
 
	<servlet>
		<servlet-name>mvc-dispatcher</servlet-name>
		<servlet-class>
                       org.springframework.web.servlet.DispatcherServlet
                </servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>
 
	<servlet-mapping>
		<servlet-name>mvc-dispatcher</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
 
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/mvc-dispatcher-servlet.xml</param-value>
	</context-param>
 
	<listener>
		<listener-class>
                      org.springframework.web.context.ContextLoaderListener
                </listener-class>
	</listener>
</web-app>

并在WEB-INF文件夹下增加文件mvc-dispatcher-servlet.xml

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	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/context/spring-context-3.0.xsd">
 
	<context:component-scan base-package="com.zhi_qingchun.testSpringMVC" />
 
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix">
			<value>/WEB-INF/pages/</value>
		</property>
		<property name="suffix">
			<value>.jsp</value>
		</property>
	</bean>
 
</beans>

4、编写控制器和视图

HelloController .java文件

@Controller
@RequestMapping("/welcome")
public class HelloController {
 
	@RequestMapping(method = RequestMethod.GET)
	public String printWelcome(ModelMap model) {
 
		model.addAttribute("message", "Spring 3 MVC Hello World");
		return "hello";
 
	}
 
}

WEB-INF/pages/hello.jsp文件

<html>
<body>
	<h1>Message : ${message}</h1>	
</body>
</html>

部署到tomcat运行，输入http://localhost:8080/SpringMVC/welcome

即可以看到以下结果
