java - 无法找到命名空间的 NamespaceHandler [http ://www. springframework.org/schema/context]

Question

当我尝试运行我的应用程序时，我总是会收到错误消息:无法找到命名空间 [http://www.springframework.org/schema/context] 的 NamespaceHandler。我不知道出了什么问题。所以这是我的 application-context.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:ws="http://jax-ws.dev.java.net/spring/core"
    xmlns:wss="http://jax-ws.dev.java.net/spring/servlet"
    xsi:schemaLocation="
            http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
            http://jax-ws.dev.java.net/spring/core http://jax-ws.dev.java.net/spring/core.xsd
            http://jax-ws.dev.java.net/spring/servlet http://jax-ws.dev.java.net/spring/servlet.xsd">

    <import resource="classpath:datasource.xml" />

    <!-- Register @Autowired annotation -->
    <bean
        class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor" />

    <context:component-scan base-package="pl.edu.pk" />

    <wss:binding url="/StudentService.ws">
        <wss:service>
            <ws:service bean="#studentServiceEndpoint"></ws:service>
        </wss:service>
    </wss:binding>

    <bean id="studentServiceEndpoint" class="pl.edu.pk.webservices.StudentServiceEndpoint" />

</beans>

这是我的 pom.xml

我找不到问题所在；/应该是库问题，但哪里出了问题？

Answer 1

这通常是因为您的类路径中缺少 spring-context.jar。尝试将 spring-context 依赖项添加到您的 pom.xml

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-context</artifactId>
  <version>${spring.version}</version>
</dependency>
