## 二、编写程序 ##

### 1、配置pom依赖 ###

                <scope>provided</scope>
            </dependency>

### 2、创建web.xml ###

**在webapp-WEB-INF下创建web.xml**

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
             version="4.0">
    
        <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:springmvc.xml</param-value>
            </init-param>
        </servlet>
        <servlet-mapping>
            <servlet-name>springmvc</servlet-name>
            
            <url-pattern>/</url-pattern>
        </servlet-mapping>
    </web-app>

### 3、创建springmvc.xml ###

**在src-main-resources下创建springmvc.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/beans
           http://www.springframework.org/schema/beans/spring-beans.xsd
           http://www.springframework.org/schema/mvc
           https://www.springframework.org/schema/mvc/spring-mvc.xsd
           http://www.springframework.org/schema/context
           https://www.springframework.org/schema/context/spring-context.xsd">
    
        
        <context:component-scan base-package="com.wangsiqi.controller"/>
        
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/WEB-INF/jsp/"/>
            <property name="suffix" value=".jsp"/>
        </bean>
        
        <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>
    
        
        <bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>
        
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/WEB-INF/views/"></property>
            <property name="suffix" value=".jsp"></property>
        </bean>
        
        <bean name="/helloworld" class="com.wangsiqi.controller.TestController"></bean>
        
        
        
        <mvc:annotation-driven></mvc:annotation-driven>
    </beans>

### 4、创建TestController类 ###

**在src-main-java-com.controller下创建TestController类**

@RestController
        @RequestMapping("/test")
        public class TestController {
        
            @GetMapping("/hello")
            public String hello(){
        
                return "hello";
            }
        }

## 三、配置Tomcat ##

**1、文件(Feild)-项目结构(Project structure)-工件(Artifacts)-Web应用程序：展开型(Web Aplication:Exploded)-基于模块(From Modules)-选择需要配置的模块名称，然后点击Facet-Web下的模块，进行路径配置**  
![在这里插入图片描述][3e1ba1171bb4417681436204d5e5042d.png]  
**2、点击项目右上角编辑配置(Edit Configurations)-左上角±Tomcat服务器(Tomcat Server)-本地(localhost)**

**3、设置路径**  
![在这里插入图片描述][9d96c6c17d3041569c8759087a640ffd.png]  
**4、设置部署(Deployment)-工件(Artifact)，需注意应用程序上下文(Application context)的路径和服务器(Server)中的URL一致**
