在Spring XML配置中使用p和util命名空间的正确方法 [英] Correct way to utilize p and util namespace in Spring XML Configuration
问题描述
我的目标是将xml文件的sessionFactory部分重写为与xml文件中所有其他区域相同的格式。我需要使用p命名空间来使事物看起来一致和整洁。我遇到的问题是使用util / p命名空间。
My goal is to rewrite the sessionFactory section of my xml file into the same format as all other areas in my xml file. I need to use the p-namespace to make things look consistent and neat. The problem that I ran into is using the util/p namespace.
感谢您让我编辑此帖子。这是我的整个xml文件：

这是我到目前为止 - 使用util：list和util：properties的组合：
This is what I have so far - using a combination of util:list and util:properties:
<util:list id="mappingResourcesList">
<value>/com/bookstore/domain/Book.hbm.xml</value>
</util:list>
<util:properties id="hibernatePropertiesProps">
<prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</util:properties>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"
p:dataSource-ref="dataSource"
p:mappingResources-ref="mappingResourcesList"
p:hibernateProperties-ref="hibernatePropertiesProps" />
我目前收到的有关util：list的错误消息，但我同样如此怀疑我的util：属性：
The error message that I'm getting currently pertains to the util:list, but I'm equally suspicious of my util:properties as well:
Exception in thread "main" org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException:
Line 22 in XML document from class path resource [application.xml] is invalid;
nested exception is org.xml.sax.SAXParseException: cvc-complex-type.2.4.c:
The matching wildcard is strict, but no declaration can be found for element 'util:list'.
我的util：list和util：属性的哪一部分必须更改才能使其生效？
What part of my util:list and util:properties must I change to get this to work?
推荐答案
XML命名空间的作用 p 和 util 映射到？这些需要用 xmlns声明：p =...和 xmlns：util =... XML元素中的某个位置或正在使用它们的父元素。
What XML namespaces do p and util map to? These need to be declared with xmlns:p="..." and xmlns:util="..." somewhere within the XML element or a parent element of which they are being used.
（您收到的错误并非特定于SAX，而是XML的通用错误解析。）
(The error you're receiving is not specific to SAX, but is generic to XML parsing.)
例如，对于使用 util ，您的XML应该从以下开始：
For example, for using util, your XML should begin with the following:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd">
Additional details are available at http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/xsd-config.html#xsd-config-body-schemas-util.
For p ，您还要添加：
For p, you'd also want to add:
xmlns:p="http://www.springframework.org/schema/p"
请注意，没有任何要求你使用 p：和 util：。这些只是按惯例使用。您可以重写XML以使用 a：和 b：无处不在 - 只要它们被定义为映射到相同的XML名称空间。 （这就是他们需要定义的原因。）
Note that nothing requires you to use p: and util:. These are simply being used by convention. You could rewrite your XML to use a: and b: everywhere - as long as they are defined to map to the same XML namespaces. (This is why they need to be defined.)
