Spring 3.1 没有 xml，只是配置不起作用

Question

所以我正在尝试实现 Spring 3.1 博客文章中提到的关于 From XML to @Configuration 的内容，但它不想按预期工作。这是我正在使用的 web.xml（这是唯一的 xml），MvcFeatures 和 MvcBeans 或多或少与博客中的相同，只是添加了一些我的 bean。

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">

    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

        <init-param>
            <param-name>contextClass</param-name>
            <param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
        </init-param>

        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>
                com.example.config.MvcFeatures 
                com.example.config.MvcBeans
            </param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <welcome-file-list>
        <welcome-file></welcome-file>
    </welcome-file-list>

</web-app>

当尝试启动这个东西时，我在控制台中收到这些消息：

21 Mar 2011 00:52:58,203 INFO  org.springframework.web.context.support.AnnotationConfigWebApplicationContext []: No annotated classes found for specified class/package [com.example.config.MvcFeatures]
21 Mar 2011 00:52:58,203 INFO  org.springframework.web.context.support.AnnotationConfigWebApplicationContext []: No annotated classes found for specified class/package [com.example.config.MvcBeans]

有什么想法可能是错的吗？据我了解，我认为它不喜欢 contextConfigLocation 参数值。

编辑：添加 MvcFeatures 以防万一。

@FeatureConfiguration
public class MvcFeatures {

    /**
     * Enables the Spring MVC @Controller programming model.
     */
    @Feature
    public MvcAnnotationDriven annotationDriven(ConversionService conversionService) {
        return new MvcAnnotationDriven().conversionService(conversionService)
                .argumentResolvers(new CustomArgumentResolver());
    }

    /**
     * Maps '/' requests to the 'home' view.
     */
    @Feature
    public MvcViewControllers viewController() {
        return new MvcViewControllers("/", "index");
    }

    /**
     * Enables Spring's component scanning feature.
     */
    @Feature
    public ComponentScanSpec componentScan() {
        return new ComponentScanSpec("com.example.controllers").excludeFilters(
                new AnnotationTypeFilter(Configuration.class), new AnnotationTypeFilter(
                        FeatureConfiguration.class));
    }
}

Answer 1

试试

    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            com.example.config.**
        </param-value>
    </init-param>

或者根据文档设置分隔符：

Configuration locations must consist of one or more comma- or space-delimited 
fully-qualified @Configuration classes. Fully-qualified packages may also 
be specified for component-scanning

Answer 2

理查兹，试试这些。

1. contextConfigLocation = com.example.config
2. 用@Configuration 和@EnableWebMvc 标记MvcFeatures 类
