MyBatis-Plus 3.3.1生成代码后，在controller注入service失败

当前使用版本(必填,否则不予处理)

mybatis-plus-boot-starter 3.3.1 mybatis-plus-generator 3.3.1

该问题是如何引起的？(确定最新版也有问题再提!!!)

生成代码之后，在controller注入service失败

重现步骤(如果有就写完整)

引入依赖

        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.3.1</version>
        </dependency>

        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-generator</artifactId>
            <version>3.3.1</version>
        </dependency>

        <dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity-engine-core</artifactId>
            <version>2.0</version>
        </dependency>

生成代码 service代码

public interface IUserService extends IService<User> {

}

serviceImpl代码

@Service
public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements IUserService {

}

controller代码

@RestController
@RequestMapping("/sys/user")
@RequiredArgsConstructor
public class UserController {

    private final IUserService service;
}

启动时报错

报错信息

Parameter 0 of constructor in com.jnh.web.bussiness.sys.controller.UserController required a single bean, but 2 were found: - UserServiceImpl: defined in file [D:\Project\yzgt\web\target\classes\com\jnh\web\bussiness\sys\service\impl\UserServiceImpl.class] - IUserService: defined in file [D:\Project\yzgt\web\target\classes\com\jnh\web\bussiness\sys\service\IUserService.class]

Action:

Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed
