springBoot mybatis 包扫描
@MapperScan(basePackages = {"com.zscat.*.dao","com.zscat.*.*.dao"})
@EnableTransactionManagement(proxyTargetClass = true) @SpringBootApplication @MapperScan(basePackages = {"com.zscat.*.dao","com.zscat.*.*.dao"}) public class ShopServiceApplication { public static void main(String[] args) { SpringApplication application = new SpringApplication(ShopServiceApplication.class); application.run(args); } }
springBoot 扫描不到 mybatis 接口包
只需要在spring boot启动类上加上注解,并指定jar包中接口文件包路径即可
@MapperScan(basePackages = "com.xx.**.dao")
如果使用@Controller和@EnableAutoConfiguration 注解还应该再加上一个注解:@ComponentScan 就可以了。
@Controller和@EnableAutoConfiguration没有扫描注解的功能,而@ComponentScan是
springboot专门用来扫描@Component, @Service, @Repository, @Controller等注解的注解
总结:
使用springboot启动类配置扫描的两种注解配置方式:
1、@Controller
@EnableAutoConfiguration @ComponentScan
2、@SpringBootApplication
@SpringBootApplication注解等价于@Configuration, @EnableAutoConfiguration and @ComponentScan
另外application.java(启动类)也应该按照官方的建议放在root目录下,这样才能扫描到Service和dao,不然还会引起,扫描不到注解的问题。

最近用了最新的springboot 2.0.5.RELEASE 版本 多了一种新的扫描注解,新版的springboot application可以放在任意位置,只要加上
@ComponentScan(basePackages = {"com.oskyhang", "com.frames"})
注解就可以,注解指定扫描的包,就可以扫描到,更灵活方便。
以上为个人经验,希望能给大家一个参考,也希望大家多多支持自由互联。
