maven+springMVC搭建
1，创建一个maven项目：
image
image
image
image
项目创建完毕：
image
2，修改pom.xml，加入HttpServlet类以及springMVC
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>4.1.2.RELEASE</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.1.2.RELEASE</version>
<scope>compile</scope>
</dependency>
然后可以看到：

3，修改web.xml文件：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 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_3_0.xsd">
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
image
注意：上下servlet-name保持一致
项目会自动去WEB-INF下寻找'servlet-name'-servlet.xml（此处对应为spring-servlet.xml）
在WEB-INF下创建文件spring-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:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc"
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
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- 配置扫描的包 -->
<context:component-scan base-package="com.springdemo.*" />
<!-- 默认的注解映射的支持 -->
<mvc:annotation-driven />
<!-- 访问静态资源 -->
<mvc:default-servlet-handler />
<!-- 视图解析器 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>
1，语句
会从com.springdemo下所有的包中搜寻所有的注解
2，这里有设定（粗体字）视图文件的路径
所以，创建com.springdemo.controller包，并创建controller：
image
package com.springdemo.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("/demo")
public class DemoController {
@RequestMapping("/index")
public String index(){
return "index";
}
}
再在WEB-INF/view下创建index.jsp文件
然后访问http://127.0.0.1:8080/springDemo/demo
