基于Spring注释的配置中的mvc：default-servlet-handler的等价物？ [英] Equivalent of mvc:default-servlet-handler in Spring annotation-based configuration?

问题描述

是否可以在 AnnotationConfig（Web）ApplicationContext中定义等效的< mvc：default-servlet-handler /> ？现在我有：

Is it possible to have the equivalent of <mvc:default-servlet-handler/> defined in an AnnotationConfig(Web)ApplicationContext? Right now I have:

@Configuration
@ImportResource("classpath:/mvc-resources.xml")
class AppConfig {
  // Other configuration...
}

在我的 resources / mvc-resources.xml中只有以下内容：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    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/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<mvc:default-servlet-handler/>
</beans>

它按预期工作。是否可以在不导入XML文件的情况下执行此操作？这将是一个减少一些样板的好方法。

And it works as expected. Is it possible to do this without importing an XML file? It would be a nice way to cut down on some boilerplate.

推荐答案

在深入挖掘之后，我发现这是一个已知问题，将在即将发布的中通过注释功能解决春季3.1 。

After digging a bit deeper, I found out that this is a known problem and is addressed by annotation features in the upcoming Spring 3.1.

我用以下代码解决了我的问题：

I solved my problem with the following code:

@Configuration
@Import(FeatureConfig.class)
class AppConfig {
   ...
}

@FeatureConfiguration
class FeatureConfig {
  @Feature
  public MvcDefaultServletHandler defaultHandler() {
    return new MvcDefaultServletHandler();
  }
}

这需要使用spring的里程碑版本，尽管，但它似乎是最清洁和首选的处理方式。

This does require using the milestone version of spring, though, but it seems to be the cleanest and preferred way of handling this.
