SpringBoot中Swagger2多包扫描问题

Swagger在POM配置好后，修改SwaggerConfig类，我只贴出要修改的，直接用

/**注意导入包是否齐全**/
import com.google.common.base.Optional;
import com.google.common.base.Predicate;
import com.google.common.base.Function;

                .select()
                // 指定当前包路径，这里就添加了两个包，注意方法变成了basePackage，中间加上成员变量splitor
                .apis(basePackage("com.XX.api.controller.broad"+splitor+"com.XX.api.controller.village"))
                // 扫描所有 .apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.any())
                .build();
    }

    /**
     * 添加摘要信息
     * 这里是接口的描述配置，不重要
     */
    private ApiInfo apiInfo()
    {
        // 用ApiInfoBuilder进行定制
        return new ApiInfoBuilder()
                .title("XXX系统_接口文档")
