spring 字节的 UTF-8 序列的字节 3 无效

最近在调试一些关于spring 的功能,自己搭建了一个小环境.

可是在配置了xml之后就出现如下的错误.

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Failed to import bean definitions from relative location [spring-db.xml]
Offending resource: class path resource [spring-context.xml]; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [spring-db.xml]; nested exception is com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: 3 字节的 UTF-8 序列的字节 2 无效。

经过一番狗血的查找之后.搜索到两个办法。
第一,可以直接在XML文件中更改UTF-8为GBK或GB2312

第二,可以在Eclipse中更改,在 eclipse 的功能表 [Project]→[Properties],點選 [Resources],在右邊的「Text file encoding」,把原來是系統預設的編碼,改為 「UTF-8」。

第一种方案可行,属于逃避的方法,放弃!第二种也不是解决我这种问题的,继续网上搜索惊奇的发现,原来解决方案是这样的:

把xml的encoding属性值UTF-8改为UTF8

重启解决问题

对此我只能呵呵…
