当我跟着字面意思去找BUG的时候,我的理解,他的错误应该就是在MenuMapper.xml文件中,但是当我找了一个多小时之后还是没找到,最后一句下面这句话,定位208行
Error creating document instance. Cause: org.xml.sax.SAXParseException; lineNumber: 208; columnNumber: 15; 元素类型为 "include" 的内容必须匹配 "((property)+)?"。
然后我一个一个去找各个mapper.xml文件中的208行,发现:
select from srwebseo_website_rapconfig where website_id = #{websiteId};
原来是多写了 include>标签,这里我们将include标签改成单标签即可。
这里,补充一个知识点:
SAXParseException: 解析xml格式字符串异常
