创建SpringMVC项目（maven）

创建一个maven项目









创建对应文件目录：



刚建好的项目，页面会有红杠（不确定是否所有版本的eclipse创建的都有），在pom中引入下面的就可以了：

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency>

在pom文件中引入需要的SpringMVC，做测试用根据自己的需求引用适当的，不需要的可以删除：

<!-- 添加Spring-core包 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring-framework.version}</version>
</dependency>
<!-- 添加Spring-bean包 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>${spring-framework.version}</version>
</dependency>
<!-- 添加spring-context包 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${spring-framework.version}</version>
</dependency>
 
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>${spring-framework.version}</version>
</dependency>
 
<!--添加spring-web包 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring-framework.version}</version>
</dependency>
<!-- 添加Spring MVC -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring-framework.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
<version>${spring-framework.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-expression</artifactId>
<version>${spring-framework.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>${spring-framework.version}</version>
<scope>compile</scope>
</dependency>

配置spring-mvc.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:mvc="http://www.springframework.org/schema/mvc"  

     xmlns:context="http://www.springframework.org/schema/context"

     xsi:schemaLocation="

     http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
     http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
    
<mvc:annotation-driven />  
<mvc:default-servlet-handler/>
<context:component-scan base-package="com.test.springMVC.*"/>
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />  

    <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"></bean>  

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

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

    </bean> 

    

</beans>

开启注解扫描,注入了AnnotationMethodHandlerAdapter作用是对有RequestMapping注解的控制器进行HTTP路径、HTTP方法和请求参数解析.DefaultAnnotationHandlerMapping作用是映射处理程序方法级别的HTTP路径.在spring 3.1之后由RequestMappingHandlerAdapter和RequestMappingHandlerMapping代替

在web.xml加入对应信息：

<filter>
<filter-name>Encoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>Encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<servlet>
<servlet-name>dispatcher</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>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
<url-pattern>*.html</url-pattern>
</servlet-mapping>

创建对应目录：

package com.test.springMVC.action;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

@Controller

public class TestController {

@RequestMapping(value = "/hello")
public String hello() {
return "hello";
}

}

通过Tomcat启动（Tomcat与jdk的配置就不写了，不会的百度查查）：
