# 启动类中配置扫描包

SpringBootPlusApplication.java

  • scanBasePackages 配置扫描的多个包
// ...
@SpringBootApplication(scanBasePackages = {"io.geekidea.springbootplus","com.example"})
public class SpringBootPlusApplication {
    // ...
}

# application.yml配置swagger扫描包路径

使用分号隔开,Swagger2Config类中进行拆分

swagger:
  base:
    package: io.geekidea.springbootplus;com.example

# Swagger2Config类配置
