Property 'mapperLocations' was not specified

回答: 当出现Property 'mapperLocations' was not specified的提示时，可能是因为没有指定mybatis-plus的mapper文件的位置。有几种解决方案可以解决这个问题。其中一种方案是将mapper文件放在resources目录下的mapper文件夹中。这样做无需任何配置，也不会提示Property 'mapperLocations' was not specified。因为mybatis-plus的mapper-locations的默认值就是classpath*:/mapper/**/*.xml。\[1\]另一种方案是将mapper文件放在与UserMapper的包目录下，并在application.yml中添加配置mapper-locations: classpath*:com/jiguangchao/mybatisplus_01_quickstart/mapper/**/*.xml。这样做可以遵循maven项目规定，程序不会报错。但是如果不添加mapper-locations配置就会提示Property 'mapperLocations' was not specified。\[2\]此外，即使出现Property 'mapperLocations' was not specified的提示，可能不会影响项目的运行。这可能是因为mybatis-plus有默认的mapper文件位置配置。\[3\]
