Question

我的应用程序工作正常，直到今天早上，但我在今天早上重命名我的Netbeans 6.9项目后开始收到以下错误。

构建Spring 3.0.4应用程序时出现以下错误：

The prefix "p" for attribute "p:driverClassName" associated with an element type "beans:bean" is not bound

的applicationContext.xml：

    </beans>

的applicationContext安全：

    </http>


    <authentication-manager>
        <authentication-provider user-service-ref='myUserDetailsService'/>
    </authentication-manager>

    <beans:bean id="myUserDetailsService"
      class="org.springframework.security.core.userdetails.jdbc.JdbcDaoImpl">
        <beans:property name="dataSource" ref="TT-SQLServer"/>
    </beans:bean>
</beans:beans>

这里看错了什么？

Answer 1

您需要在bean声明中添加名称空间。

的xmlns：C =＆＃34; HTTP：//www.springframework.org/schema/c" 的xmlns：P =＆＃34; HTTP：//www.springframework.org/schema/p"

请参阅spring文档参考。

http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/beans.html#beans-p-namespace

Answer 2

我对Netbeans没有任何经验，但我想这个问题可能与p命名空间的XML模式有关。

这是一个疯狂的猜测，但让我接受它。也许您已将Netbeans配置为在其目录中添加自定义XSD并指向项目中的XSD文件。重命名项目后，p命名空间XML架构的路径无效。

我甚至不知道在Netbeans中是否可以进行这样的XML目录配置，我更喜欢Eclipse。但我会在你的位置检查一下。

Answer 3

我知道我迟到了但我得到了同样的错误，可能这对其他人有用..我把

p:something

进入

<property name="something" value="anything_you_want_to_set"/>

所以，而不是

p:driverClassName="net.sourceforge.jtds.jdbc.Driver"

试试这个：

<bean>
    <property name="driverClassName" value="net.sourceforge.jtds.jdbc.Driver" />
    <!-- and your others property -->
</bean>
