錯誤類型：cvc-complex-type-2-3

該錯誤的類型如下：

cvc-complex-type-2-3

 Element ''{0}'' cannot have character [children], because the type''s content type is element-only.

在XML中是一般來說是不允許一些字符作爲定義外的元素存在的，要不然就會報如下的類似錯誤了：

Caused by: org.xml.sax.SAXParseException; lineNumber: 83; columnNumber: 9; cvc-complex-type.2.3: Element 'beans' cannot have character [children], because the type's content type is element-only.
