    从你提供的错误信息来看，Spring Boot在尝试绑定mapper属性到tk.mybatis.mapper.entity.Config时遇到了问题。它找不到一个合适的转换器来将字符串转换为tk.mybatis.mapper.entity.Config类型。

    在你的application.properties文件中，你似乎没有为tk.mybatis的mapper属性设置任何值。可能的问题是，Spring Boot试图读取这个属性，但是由于找不到它，所以尝试使用默认值，而这个默认值可能是一个字符串，而不是tk.mybatis.mapper.entity.Config类型的对象。

    解决这个问题的方法可能有两种：

    1. 确保你的application.properties文件中包含tk.mybatis的mapper属性的正确设置。如果tk.mybatis.mapper.entity.Config类有默认的构造函数和必要的setter方法，那么你可能只需要提供一个字符串形式的配置路径。然而，由于我没有tk.mybatis.mapper.entity.Config类的具体信息，所以我无法给出具体的设置值。
    2. 如果你不需要在application.properties文件中设置tk.mybatis的mapper属性，你可以尝试在你的配置类中使用@ConfigurationProperties注解来忽略这个属性。例如：
    @Configuration
@ConfigurationProperties(ignoreUnknownFields = true)
public class MybatisConfig {
    // 其他属性...
}

    在这个例子中，ignoreUnknownFields = true会告诉Spring Boot忽略任何在application.properties文件中定义但在MybatisConfig类中不存在的属性。

    以上都是基于我对你问题的理解给出的建议，由于我缺乏关于你的tk.mybatis.mapper.entity.Config类的具体信息，所以可能需要你进行一些调整。如果问题仍然存在，我建议你查看tk.mybatis的文档，看看是否有关于如何正确设置mapper属性的信息。
