本文介绍了一个基于Spring MVC的Web应用配置过程，包括视图解析器的设置、初始化器的实现及控制器的定义。同时展示了如何通过配置处理静态资源如JS、CSS和图片等文件。

resources 下新建 views文件夹下新建index.jsp；

@Configuration
@EnableWebMvc
@ComponentScan("com.hui.MySpringMVC")
public class MyMvcConfig {
    @Bean
    public InternalResourceViewResolver viewResolver(){
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("/WEB-INF/classes/views/");
        viewResolver.setSuffix(".jsp");
        viewResolver.setViewClass(JstlView.class);
        return viewResolver;
    }
}

public class WebInitializer implements WebApplicationInitializer {
    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
        context.register(MyMvcConfig.class);
        context.setServletContext(servletContext);
        Dynamic servlet = servletContext.addServlet("dispatcher",new DispatcherServlet(context));
        servlet.addMapping("/");
        servlet.setLoadOnStartup(1);
    }
}

@Controller
public class HelloController {
    @RequestMapping("/index")
    public String hello(){

        return "index";
    }
}

第一次运行的时候配置文件忘了@ComponentScan("com.hui.MySpringMVC")导致404错误

idea配置tomvat时需要artifact 选exploded 右侧输入 application context /test 也可不输入

静态资源

在resource下新建assets文件夹存放js、css、图片

@Configuration
@EnableWebMvc
@ComponentScan("com.hui.MySpringMVC")
public class MyMvcConfig extends WebMvcConfigurerAdapter {
    @Bean
    public InternalResourceViewResolver viewResolver(){
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("/WEB-INF/classes/views/");
        viewResolver.setSuffix(".jsp");
        viewResolver.setViewClass(JstlView.class);
        return viewResolver;
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/assets/**").addResourceLocations("classpath:/assets/");
    }
}
