MapperScan scans to the specified package
@SpringBootApplication
#错误：要扫描指定的mapper包下
@MapperScan(basePackages = "com.atdession")
public class BillMain {
public static void main(String[] args) {
SpringApplication.run(BillMain.class,args);
}
}solve
Because my MapperScan scan is a full scan, just specify MapperScan to scan the Mapper package.
@SpringBootApplication
@MapperScan(basePackages = "com.atdession.mapper")
public class BillMain {
public static void main(String[] args) {
SpringApplication.run(BillMain.class,args);
}
}
