在Spring Boot中配置DispatcherServlet

现有一项目，两套API，由于使用同一域名，需要采用URI部分增加命名空间来区分，采取修改DispatcherServlet映射路径的方式进行配置。

Spring Boot 编程式配置

    @Bean
    public ServletRegistrationBean dispatcherRegistration(DispatcherServlet dispatcherServlet) {
        return new ServletRegistrationBean(dispatcherServlet,"/web/*");
    }

传统配置方式

 <!--Spring MVC 配置-->
    <servlet>
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:conf/spring-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/web/*</url-pattern>
    </servlet-mapping>
