通过myabatis generator 生成的对应mapperxml、dao、model，因为还要自定义，有的文件就重名了，请问除了改文件名，还有什么方法可以解决，求帮助~

https://developer.aliyun.com/profile/5yerqm5bn5yqg?spm=a2c6h.12873639.0.0.6eae304abcjaIB<p>应该可以分别指定扫描的package吧</p> 好的，我先试试 <p>首先这个跟spring boot没有关系，跟mybatis注册mapper的BeanName有关，你自定义beanNameGenerator就行了</p> <p>通过查看Spring源码得知，当我们使用注解创建bean时，spring使用了AnnotationBeanNameGenerator来创建bean的名称。<br> 解决方案：自己写一个Generator吧。如下：</p>@SpringBootApplication @ComponentScan(nameGenerator = MultidataApplication.SpringBeanNameGenerator.class) public class MultidataApplication { public static class SpringBeanNameGenerator extends AnnotationBeanNameGenerator { @Override protected String buildDefaultBeanName(BeanDefinition definition) { return definition.getBeanClassName(); } } public static void main(String[] args) { SpringApplication.run(MultidataApplication.class, args); } }Mybatis的MapperScan里新增：
nameGenerator = MultidataApplication.SpringBeanNameGenerator.class示例：
@MapperScan(basePackages="com.onlyas.appserver.dao", nameGenerator = MultidataApplication.SpringBeanNameGenerator.class)2020-06-07 18:05:14赞同 展开评论 打赏
