導入dubbo項目到Eclipse，配置文件報了如下異常：
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>.
解決方案：
1、下載一個dubbo.xsd文件
2、windows->preferrence->xml->xmlcatalog
add->catalog entry->file system選擇剛剛下載的文件路徑
key type選擇schema locaiton
修改key值和配置文件的http://code.alibabatech.com/schema/dubbo/dubbo.xsd 相同
