我的问题

@SpringBootApplication
@EnableAsync
public class AppWebApplication {
    public static void main(String[] args) {
        SpringApplication.run(AppWebApplication.class,args);
    }
}

    @Autowired
    private LeaseAgreementService service;

    @Operation(summary = "获取个人租约基本信息列表")
    @GetMapping("listItem")
    public Result<List<AgreementItemVo>> listItem() {
        List<AgreementItemVo> result = service.listItemByPhone(LoginUserHolder.getLoginUser().getUsername());
        return Result.ok(result);
    }

@Service
public class LeaseAgreementServiceImpl extends ServiceImpl<LeaseAgreementMapper, LeaseAgreement>
        implements LeaseAgreementService {

    @Autowired
    private LeaseAgreementMapper leaseAgreementMapper;

    @Override
    public List<AgreementItemVo> listItemByPhone(String username) {
        return leaseAgreementMapper.listItemByPhone(username);
    }
    .....
    }

public interface LeaseAgreementMapper extends BaseMapper<LeaseAgreement> {

    List<AgreementItemVo> listItemByPhone(String username);
}

就如上面的，能配置的地方我都配置了，最后的我采取的解决办法是下面的

@MapperScan("com.miaow.lease.web.app.mapper") // 扫描mapper接口的包路径

错误描述和解决办法

这个错误表明Spring无法找到一个符合条件的LeaseAgreementMapper类型的bean。这通常是因为LeaseAgreementMapper没有被正确地注册到Spring的bean工厂中。你可以尝试以下步骤来解决这个问题：

• 确保LeaseAgreementMapper接口继承了Mapper接口（如果使用MyBatis），并且你的项目中包含了MyBatis的自动配置。
• 确保你的Mapper接口放置在正确的包下，Spring会自动扫描指定包及其子包下的bean。如果LeaseAgreementMapper接口不在被扫描的包下，你需要在@SpringBootApplication注解上添加@ComponentScan注解，并指定包含LeaseAgreementMapper接口的包路径。
• 如果你使用的是MyBatis-Spring-Boot-Starter，确保在配置文件中正确配置了数据库连接信息和MyBatis的相关配置。
• 确保你的LeaseAgreementMapper接口已经被正确地实现了，并且这个实现类被注册为一个Spring bean。你可以使用@MapperScan注解来扫描所有的Mapper接口，并自动创建它们的实现类作为bean。例如：

   @SpringBootApplication
   @MapperScan("com.miaow.lease.web.app.mapper") // 扫描mapper接口的包路径
   public class AppWebApplication {
       public static void main(String[] args) {
           SpringApplication.run(AppWebApplication.class,args);
       }
   }

或者，你也可以为每个Mapper接口创建一个实现类，并使用@Component或@Service注解将其实现类注册为一个Spring bean。

• 如果以上步骤都没有解决问题，你可以尝试在LeaseAgreementServiceImpl中手动创建LeaseAgreementMapper的实例，而不是通过@Autowired自动注入。例如：

 @Service
   public class LeaseAgreementServiceImpl implements LeaseAgreementService {
       
       private final LeaseAgreementMapper leaseAgreementMapper;
       
       public LeaseAgreementServiceImpl(LeaseAgreementMapper leaseAgreementMapper) {
           this.leaseAgreementMapper = leaseAgreementMapper;
       }
       
       // ...
   }

然后在你的配置类中使用@Bean注解来创建LeaseAgreementMapper的实例：

   @Configuration
   public class AppConfig {
       
       @Bean
       public LeaseAgreementMapper leaseAgreementMapper() {
           // 创建LeaseAgreementMapper的实例并返回
           // 例如使用MyBatis的SqlSessionFactory来创建Mapper实例
           return new LeaseAgreementMapper();
       }
   }
