Spring-dispatcher-servlet.xml到Java Config

Question

您好我正在尝试将我的Xml配置转换为Java Config。我现在真的输了。

这是 spring-dispatcher-servlet.xml

    <!-- This transaction manager is appropriate for applications that use a

以下是我为 Java Config 提出的建议。

@Configuration
@EnableWebMvc
@ComponentScan("com.test")
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addResourceHandlers(final ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/Resources/**")
                .addResourceLocations("/Resources/").setCachePeriod(31556926);
    }

    @Override
    public void configureDefaultServletHandling(
            DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

    @Bean
    public ViewResolver setupViewResolver(ContentNegotiationManager manager) {
        List<ViewResolver> resolvers = new ArrayList<ViewResolver>();


        InternalResourceViewResolver InternalResourceResolver = new InternalResourceViewResolver();
        InternalResourceResolver.setPrefix("/WEB-INF/jsp/");
        InternalResourceResolver.setSuffix(".jsp");
        resolvers.add(InternalResourceResolver);

        ContentNegotiatingViewResolver resolver2 = new ContentNegotiatingViewResolver();
        resolver2.setViewResolvers(resolvers);
        resolver2.setContentNegotiationManager(manager);
        return resolver2;

    }
}

非常感谢您的帮助。
