错误在Xml文件多个Anontations中无法理解

Question

我将Eclipse中的项目错误输入到我的XML文件中：

Multiple annotations found at this line:
    - cvc-elt.1: Cannot find the declaration of element 'beans'.
    - schema_reference.4: Failed to read schema document 'http://
     www.springframework.org/schema/beans/spring-beans-3.0.xsd', because 1) could not find the 
     document; 2) the document could not be read; 3) the root element of the document is not 
     <xsd:schema>.

当我只写一个空格然后保存文件时，错误消失，但在它再次返回之后。任何艾迪亚？谢谢
