SpringMVC跨伺服器上傳檔案出現的問題

一、上傳檔案檔名有中文，會報400錯！

Type 異常報告

解決方法：刪除上傳檔名稱的中文部分！

二、405錯誤

解決方法：改一下tomcat許可權：修改readonly為false！

相關配置(在tomcat/conf/web.xml中加):

		<init-param>
			<param-name>readonly</param-name>
			<param-value>false</param-value>
		</init-param>

三、409錯誤（接收檔案的那一端沒有生成指定的資料夾，如：upload資料夾）

解決方法：手動在接收端的WebApp下新建upload資料夾！
