春季3(SWS2):< context:component-scan>和< sws:annotation-driven> [英] Spring 3 (SWS2): difference between <context:component-scan> and <sws:annotation-driven>

问题描述

当尝试一个仅带有一个@Endpoint注释类的简单Web Service Hello World示例时，使用<sws:annotation-driven/>命名空间时不会注册端点.

When trying a simple Web Service Hello World example with just one @Endpoint annotated class, the Endpoint is not registered when using the <sws:annotation-driven/> namespace.

但是，通过添加常规的<context:component-scan>，一切正常，可以正确注册Endpoint类. 这仅对于@Endpoint注释正确，所有其他注释(@RequestPayload，@ResponsePayload，@PayloadRoot)将按预期由sws-namespace注册.

However, by adding the usual <context:component-scan>, everything works well, the Endpoint-class is registered correctly. This is only true for the @Endpoint annotation, all other annotations (@RequestPayload, @ResponsePayload, @PayloadRoot) will be registered by the sws-namespace as expected.

该名称空间是否也不能处理@Endpoint批注?

Should the @Endpoint annotation not be processed by this namespace as well?

<beans>
   <!-- works for all annotations except @Endpoint -->
    <sws:annotation-driven/>

    <!-- when activated, @Endpoint is registered correctly <context:component-scan/> -->
</beans>
