Spring mvc 是否可以将mybatis-config.xml转换为SpringMVC的类文件？

是否可以将mybatis-config.xml（文件类型为xml的sql映射配置）转换为java类文件

我尝试搜索，但只能找到映射器文件的类配置

请通过课堂让我知道这是否真的可行？

我不确定我是否理解你的问题，但请尝试以下方法：

如果您将mybatis与spring boot一起使用，请试用，然后您可以在ConfigurationCustomizer中自定义自己的配置，如下所示：

// @Configuration class
@Bean
ConfigurationCustomizer mybatisConfigurationCustomizer() {
    return new ConfigurationCustomizer() {
        @Override
        public void customize(Configuration configuration) {
            // customize ...
        }
    };
}
