RESTFUL是一种网络应用程序的设计风格和开发方式，基于HTTP，可以使用XML格式定义或JSON格式定义。RESTFUL适用于移动互联网厂商作为业务接口的场景，实现第三方调用移动网络资源的功能，动作类型为新增、变更、删除所调用资源。接下来跟着我，我们来创建第一个RESTful应用，来吧，上车。
1.创建maven工程
2.配置Project Structure
3.配置Facets，选中web项目
4.配置web相关设置
配置tomcat
新建项目之后，项目结构为：
5.在pom.xml文件中引入阿里云远程仓库和spring-webmvc
<!-- 1.引入阿里云仓库-->
<repositories>
<repository>
<id>aliyun</id>
<name>aliyun</name>
<url>https://maven.aliyun.com/repository/public</url>
</repository>
</repositories>
<!-- 2.引入spring webmvc-->
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.1.9.RELEASE</version>
</dependency>
</dependencies>
6.在web.xml新增DispatcherServerlet和CharacterEncodingFilter过滤
<!--3.引入DispatcherServerlet-->
<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:applicationContext.xml</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--4.引入字符串过滤-->
<filter>
<filter-name>characterFilter</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>
</filter>
<filter-mapping>
<filter-name>characterFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
7.resources下新增applicationContext.xml文件,配置包扫描和StringHttpMessageConverter
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mv="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/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- 5.包扫描-->
<context:component-scan base-package="com.imooc.restful"/>
<!-- 6.引入StringHttpMessageConverter-->
<mvc:annotation-driven>
<mvc:message-converters>
<bean class="org.springframework.http.converter.StringHttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<!-- response.setContentType("text/html;charset=utf-8") -->
<value>text/html;charset=utf-8</value>
<value>application/json;charset=utf-8</value>
</list>
</property>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
<mvc:default-servlet-handler/>
</beans>
