### 1、第一步：导入依赖 ###

        </dependencies>

### 2、第二步：配置web.xml ###

*  配置编码过滤器
 *  配置HiddenHttpMethodFilter
 *  配置springMVC的前端控制器DispatcherServlet

            <url-pattern>/</url-pattern>
        </servlet-mapping>
    
    </web-app>

### 3、第三步：创建控制器 ###

### 4、第四步：创建springmvc配置文件 ###

*  配置扫描组件（为了扫描@Controller等注解）
 *  配置视图解析器（为了匹配请求路径）

### 测试（访问index.html） ###

部署到tomocat服务器后，网址输入：**http://localhost:8080/day03/**  
\[day03是默认上下文路径，也就是工程名\]

**配置成功！**

**重点（请求过程）：  
浏览器发送请求，若请求地址符合前端控制器的url-pattern，该请求就会被前端控制器 DispatcherServlet处理。前端控制器会读取SpringMVC的核心配置文件，通过扫描组件找到控制器，将请求地址和控制器中@RequestMapping注解的value属性值进行匹配，若匹配成功，该注解所标识的控制器方法就是处理请求的方法。处理请求的方法需要返回一个字符串类型的视图名称，该视图名称会被视图解析器解析，加上前缀和后缀组成视图的路径，通过Thymeleaf对视图进行渲染，最终转发到视图所对应页面。**
