Question

我想在spring中为我的网站添加rss源代码，最后一步是配置CustomRssView的Bean。

但是教程使用xml来配置它。我希望使用@Bean注释。但是，它无法解析视图名称。

教程中的xml

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
    http://www.springframework.org/schema/beans     
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<context:component-scan base-package="com.mkyong.common.controller" />

<!-- Map returned view name "rssViewer" to bean id "rssViewer" -->
<bean class="org.springframework.web.servlet.view.BeanNameViewResolver" />

<bean id="rssViewer" class="com.mkyong.common.rss.CustomRssViewer" />

我的bean配置

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        ApplicationContext ctx = SpringApplication.run(Application.class, args);

        System.out.println("Let's inspect the beans provided by Spring Boot:");

        String[] beanNames = ctx.getBeanDefinitionNames();
        Arrays.sort(beanNames);
        for (String beanName : beanNames) {
            System.out.println(beanName);
        }
    }

    @Bean
    public RssView rssView() {
        return new RssView();
    }
}

注册成功，但BeanNameViewResolver无法解析视图名称。

一些调试信息

如何更改我的代码。

如何在spring中为带有注释的rssView配置Bean
