关于schema的报错问题如下，请问是怎么回事呢 ？

Question

Multiple annotations found at this line: - schema_reference.4: Failed to read schema document 'http://www.osoa.org/xmlns/sca/1.0/spring-sca.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>. - cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'sca:service'.

Answer 1

你spring配置文件的头部 schema出问题了 
1)http://www.osoa.org/xmlns/sca/1.0/spring-sca.xsd这个找不到 
3)这个文件的根元素不是<xsd:schema> 
你可以找个正确的把你这个xml配置文件的头部替换一下，不知道你使用的spring哪个版本，下面我贴一个：仅供参考，或者你可以在网上搜索一个正确的替换下： 
<?xml version="1.0" encoding="UTF-8"?> 
<beans 
xmlns="http://www.springframework.org/schema/beans" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"> 
</beans>
