不知道为什么会收到此错误。这里有很多类似的问题，但到目前为止，没有一个问题对我有用。

我的 ivy文件是

<ivy-module version="2.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:noNamespaceSchemaLocation="http://ant.apache.org/ivy/schemas/ivy.xsd">
    <info
        organisation=""
        module="knoxWeb"
        status="integration">
    </info>

    <dependencies>
        <dependency org="org.springframework" name="spring-core" rev="4.0.3.RELEASE"/>
        <dependency org="org.springframework" name="spring-context" rev="4.0.3.RELEASE"/>
        <dependency org="org.springframework" name="spring-web" rev="4.0.3.RELEASE"/>
        <dependency org="org.springframework" name="spring-webmvc" rev="4.0.3.RELEASE"/>
        <dependency org="org.springframework" name="spring-beans" rev="4.0.3.RELEASE"/>
    </dependencies>
</ivy-module>

而我的web.xml是

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>Knox Web Interface</display-name>

    <servlet>
    <servlet-name>action</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
   </servlet>
    <servlet-mapping>
        <servlet-name>action</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
</web-app>

我已经解决了 ivy。仍然有错误。我还可以在eclipse中看到这个类。

我真的很纠结于此。如有任何帮助或建议，我们将不胜感激。

PS：我也尝试添加，< dependency org="org.springframework" name="spring" rev="2.5.6"/>但常春藤无法解决。我懂了
