错误类型：cvc-complex-type-2-3

该错误的类型如下：

cvc-complex-type-2-3

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

在XML中是一般来说是不允许一些字符作为定义外的元素存在的，要不然就会报如下的类似错误了：

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.
