java匹配的通配符是严格的,但在dispatcher servlet中找不到元素“context:componentscan”错误的声明
当我试图在浏览器上查看网页时,我收到此错误
堆栈跟踪:
org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 10 in XML document from ServletContext resource [/WEB-INF/DefaultServlet-servlet.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 10; columnNumber: 71; cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'context:component-scan'.
DefaultServlet。xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

此外,我还将包括我的applicationContext
,因为它在以下代码中也有相同的代码行:
<beans xmlns="http://www.springframework.org/schema/beans"

</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

<property name="hibernateProperties">

<prop
key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"
p:sessionFactory-ref="sessionFactory">
</bean>
</beans>
我还相信我的库和pom中有正确的相关性:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${spring.version}</version>
</dependency>
# 1 楼答案
根据这个post“您没有指定上下文名称空间的模式位置,这就是这个特定错误的原因
然而,似乎你有它,所以让我们看看它还能是什么
一个选项是,您可以指定SpringBeans的版本,因为您在应用程序上下文中使用3.2,所以在DefaultServlet servlet中使用相同的版本可能会有所帮助。xml
我感到担心的另一件事是路径http://www.springframework.org/schema/p,据我所知,您不需要指定schemaLocation。这似乎是对的,但我看不出这里有多少优势,而且一些XML名称空间没有被使用。所以,我修改了它,得到了这个,如果它有帮助,试试看,希望它能
