【Spring错误】

Spring错误

背景：配置spring xml，注释xml中文件元素

错误：

Caused by: org.xml.sax.SAXParseException: cvc-complex-type.2.3: 元素 'beans' 必须不含字符 [子级], 因为该类型的内容类型为“仅元素”。

原因有二：

一：从网上粘贴过来字符没有对应上，所以子元素property报错，将文字复制到Notepad++等编辑工具，转为UTF-8编码格式

二：xml文件中有特殊字符，删除即可

原来使用了这种注释：在spring*.xml中注释使用//,被认为是字符串

//

修改方法：注释应该使用<!--   -->
