package com.pp.web;
    
    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.web.servlet.config.annotation.EnableWebMvc;
    
    /**

     */
    @EnableWebMvc
    /**
     * 设置componen的扫描包路径 
     */
    @ComponentScan("com.pp.web")
    public class AppConfig {
    
    }

package com.pp.web;
    
    import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
    
    /**
     * 系统初始化入口
     */
    public class AppDispatcherServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
    
    	/**
    	 * 设置spring容器启动的入口
    	 */
    	@Override
    	protected Class<?>[] getRootConfigClasses() {
    		return new Class<?>[]{AppConfig.class};
    	}
    
    	@Override
    	protected Class<?>[] getServletConfigClasses() {
    		return null;
    	}
    
    	/**
    	 * 设置DispatcherServlet的拦截路径
    	 */
    	@Override
    	protected String[] getServletMappings() {
    		return new String[]{"/"};
    	}
    }

package com.pp.web;
    
    import org.springframework.context.annotation.Configuration;
    import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
    import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
    
    /**

    @Configuration
    public class AppWebMvcConfigurer extends WebMvcConfigurerAdapter {
    
    	/**
    	 * 配置静态资源的映射
    	 */
    	public void addResourceHandlers(ResourceHandlerRegistry registry) {
    	    registry.addResourceHandler("/static/**").addResourceLocations("/static/");
    	}
    }

package com.pp.web.controller;
    
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class IndexController {
    
    	@GetMapping("/index")
    	public String index(){
    		return "hello index";
    	}
    }

最后，在项目的跟目录执行mvn clean jetty:run 运行项目
