搭建dubbo项目解决dubbo.xml标签报错的问题

报错内容：

Multiple annotations found at this line:

- cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration 
can be found for element 'dubbo:application'.
- schema_reference.4: Failed to read schema document 'http://
code.alibabatech.com/schema/dubbo/dubbo.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>.

解决步骤：

1.进入http://repo1.maven.org/maven2/com/alibaba/dubbo/下载相应的dubbojar包，解压拿到dubbo.xsd文件。

 

2.进入eclipse  windows-Preferences-XML-XML Catalog  点击Add添加

在Location位置选择下载的dubbo.xsd文件；

在Key位置输入：http://code.alibabatech.com/schema/dubbo/dubbo.xsd；

3.然后在dubbo.xml右击Refresh即可。
