"is ignored, because it exists, maybe from xml file"这个错误信息的意思是因为存在同名的XML文件,所以被忽略了。 这意味着在MyBatisPlus启动时,已经加载了同名的XML文件中的节点,所以忽略了来自mapper的SQLProvider数据。 为了避免这个错误,你可以检查是否存在同名的XML文件,或者确认是否需要使用SQLProvider中的数据。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

mapper is ignored, because it exists, maybe from xml file
"mapper is ignored, because it exists, maybe from xml file"这个报错信息的意思是,当MyBatisPlus启动时,发现某个映射器已经存在,可能是来自于XML文件。这个报错信息出现的原因是在加载SQL语句时的顺序问题。MyBatisPlus首先会加载XML中的SQL语句,然后加载SqlProvider中的SQL语句,但是XML中的SQL语句和SqlProvider中的SQL语句不能包含相同的内容。如果已经加载了XML中的节点,那么就会忽略掉映射器中的SqlProvider数据,并报出这个错误信息。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

mapper[] is ignored, because it exists, maybe from xml file
根据引用、[2]和的信息,当出现 "mapper[] is ignored, because it exists, maybe from xml file" 的报错信息时,意味着在 MyBatisPlus 启动时,某个映射器(mapper)被忽略了,因为它已经存在,可能是来自于 XML 文件。这个报错信息提示了在项目中存在重复定义的映射器,导致 MyBatisPlus 忽略其中一个映射器。你可以检查你的项目中的 XML 文件和代码,确保没有重复定义同一个映射器。如果确实有重复定义的映射器,你可以删除其中一个来解决这个问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
