Question

这个似乎是一个简单的问题。当我尝试在eclipse中运行或编译我的maven项目时，我收到错误：

SEVERE: Servlet /articleservices threw load() exception
org.xml.sax.SAXParseException; lineNumber: 73; columnNumber: 32; The prefix "p" for attribute "p:name" associated with an element type "bean" is not bound.
    at org.apache.xerces.util.ErrorHandlerWrapper.createSAXParseException(Unknown Source)
    at org.apache.xerces.util.ErrorHandlerWrapper.fatalError(Unknown Source)
    at org.apache.xerces.impl.XMLErrorReporter.reportError(Unknown Source)
    at org.apache.xerces.impl.XMLErrorReporter.reportError(Unknown Source)..

注意我截断了错误消息，因为我认为这个根本说明不太明确......但不管我看了多少并检查，我的配置文件似乎没有任何问题，这是如下：

            </set>
        </property>

</beans>

好吧，我只是懒得剪掉项目中使用的其他bean，但我的问题是......我实际上是为spring的缓存指定了正确的架构位置吗？或者我在这里遗漏了什么？

Answer 1

最后在spring文档中找到了这个名称空间xmlns:p="http://www.springframework.org/schema/p"

未包含在示例配置中。

Answer 2

您确定要在以下代码中编写p:name吗？

<bean class="org.springframework.cache.concurrent.ConcurrentCacheFactoryBean" p:name="rsspassthrough" />
