元素"beans:beans"的前缀"beans"未绑定

Question

我想补充CSS和JS对JSP页面中的spring MVC,这样我已经包括的参考项目js/css文件夹中dispatcher-servlet.xml,如下:

<?xml  version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">


    <context:annotation-config />
    <context:component-scan base-package="com.asurion" />

    <resources mapping="/js/**" location="/js/" />
    <resources mapping="/css/**" location="/css/" />

    <beans:bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix">
            <value>/WEB-INF/jsp/</value>
        </property>
        <property name="suffix">
            <value>.jsp</value>
        </property>
    </beans:bean>

    <beans:bean id="messageSource"
        class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
        <property name="basename" value="classpath:messages" />
        <property name="defaultEncoding" value="UTF-8" />
    </beans:bean>
    <beans:bean id="propertyConfigurer"
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"
        p:location="/WEB-INF/jdbc.properties" />

    <beans:bean id="dataSource"
        class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"
        p:driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver"
        p:url="jdbc:sqlserver://localhost:1433;DataBaseName=test" p:username="test"
        p:password="test" />


    <beans:bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="configLocation">
            <value>classpath:hibernate.cfg.xml</value>
        </property>
        <property name="configurationClass">
            <value>org.hibernate.cfg.AnnotationConfiguration</value>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">com.asurion.dialect.SQlServerDBDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
            </props>
        </property>
    </beans:bean>

    <beans:bean id="reportDAO" class="com.asurion.dao.ReportDaoImpl"></beans:bean>
    <beans:bean id="reportManager" class="com.asurion.service.ReportManagerImpl"></beans:bean>

    <tx:annotation-driven />
    <beans:bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </beans:bean>

</beans:beans>

但它显示"前缀"bean"for element"bean:bean"未绑定"在spring配置文件中,所以任何人都可以帮我解决这个问题吗？

看看你的根元素声明-您所指定的前缀命名空间mvc,xsi,context,p,和tx,但没有进行beans.您已经创建"http://www.springframework.org/schema/beans"了默认命名空间,但是您没有给它一个别名beans.

这里最简单的解决方法可能只是进行搜索并替换以beans:从整个文件中删除- 只需将默认设置放到其工作中即可.

或者,改变这个:

xmlns="http://www.springframework.org/schema/beans"

至

xmlns:beans="http://www.springframework.org/schema/beans"

...然后检查每个没有显式名称空间前缀的元素,看看你是否真的想要它beans.例如,考虑:

<resources mapping="/js/**" location="/js/" />

如果您使用显式命名空间,那可能应该是

<beans:resources mapping="/js/**" location="/js/" />

虽然这听起来像它应该实际上是

<mvc:resources mapping="/js/**" location="/js/" />

目前默认情况下它位于beans命名空间中,但默认和使用beans:前缀的混合非常令人困惑......
