错误提示

在使用SpringBoot整合mybatisplus的时候，在数据库和controller联调的时候，发现这个错误。

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.atdession.service.UserService.getBaseMapper

错误原因

MapperScan要扫描到指定的包下

@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);
    }
}

解决

因为我MapperScan扫描的时候是全盘扫描，将MapperScan指定扫描Mapper包即可

@SpringBootApplication
@MapperScan(basePackages = "com.atdession.mapper")
public class BillMain {

    public static void main(String[] args) {
        SpringApplication.run(BillMain.class,args);
    }
}

解决啦
