正确地将WebMvcConfigurerAdapter覆盖到WebMvcConfigurer

Question

我之前在2017年使用WebMvcConfigurerAdapter进行了安全层项目的登录和注册，但是现在不建议使用，因为我正在努力更新代码。

@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {

// Handles HTTP GET requests for /resources/** by efficiently serving up static 
// resources in the ${webappRoot}/resources/ directory
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}

//Resolves views selected for rendering by @Controllers to .jsp resources in the 
// /WEB-INF/views directory
@Bean
public InternalResourceViewResolver viewResolver() {
    InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
    viewResolver.setViewClass(JstlView.class);
    viewResolver.setPrefix("/WEB-INF/views/");
    viewResolver.setSuffix(".jsp");
    viewResolver.setOrder(2);
    return viewResolver;
}
@Bean
public SimpleMappingExceptionResolver simpleMappingExceptionResolver()
{
    SimpleMappingExceptionResolver b = new SimpleMappingExceptionResolver();
    Properties mappings = new Properties();
    mappings.put("eMarket.controller.SpringException", "form/ExceptionPage");
    mappings.put("defaultErrorView", "form/error");
    b.setExceptionMappings(mappings);
    return b;
}   

}

我尝试使用

@Configuration 
public class WebConfig implements WebMvcConfigurer { ... }

执行此操作时，会发生以下错误：

- The type WebConfig must implement the inherited abstract method 
 WebMvcConfigurer.configureContentNegotiation(ContentNegotiationConfigurer)
- The type WebConfig must implement the inherited abstract method WebMvcConfigurer.getValidator()
- The type WebConfig must implement the inherited abstract method 
 WebMvcConfigurer.extendMessageConverters(List<HttpMessageConverter<?>>)
