xml报错“cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element”

配置使用dubbo时，xml报错“cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element”

解决方案：

在线下载dubbo.xsd文件，放于某个文件夹。

在eclipse做如下配置：

Window—>preference—>XML—>XMLcatalog—>add，添加后右键校验XML文件即可
