The content of elements must consist of well-formed character data or markup.

下面这段【xml】文件的代码报错

报错Cause: org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 869; The content of elements must consist of well-formed character data or markup.

提给gpt和豆包，返回的错误定位都是，xml中的这句代码

order by updateTime DESC ,createTime DESC

而实际上是@Select注解中的语句有问题，太依赖AI已经没有自己分析问题的能力了 T_T

我直接给你精准定位报错位置 + 100% 能解决的方案
你这个报错：
plaintext
SAXParseException; lineNumber: 1; columnNumber: 869;
The content of elements must consist of well-formed character data or markup.
意思是：XML 语法不合法！MyBatis 解析 XML 失败！
你这个 XML 里的真凶只有一个
xml
order by  updateTime DESC ,createTime DESC
