我正在尝试运行我的项目的jar文件.我正在研究intelliJ并使用工件来生成jar文件.但每次我试图运行我的jar文件时它给我异常.

在我的项目中,我得到了一个我正在我的collectionview上加载的数组

var dataSource = ["@", "@", "1", "2", "3", "4", "5", "6", "7", "8" , "9", "10", "@", "@"]

对于字符串"@"我想隐藏该特定单元格.所以最初我试图使用indexpath,然后尝试检查我的数组位置是否得到值"@".但我无法正确隐藏它,因为其他一些单元格会在滚动时被更改

这就是我在我的cellForItemAt上所做的:

if dataSource[indexPath.row] == "@" {

            cell.contentView.isHidden = true
            cell.layer.borderColor = UIColor.white.cgColor

        }

事情被认为是水平滚动,这是我的sizeForItemAt:

func collectionView(_ collectionView: UICollectionView,
                        layout collectionViewLayout: UICollectionViewLayout,
                        sizeForItemAt indexPath: IndexPath) -> CGSize {


        return CGSize(width: (self.numberCollectionView?.bounds.size.width)!/5 - 3, height: (self.numberCollectionView?.bounds.size.width)!/5 - 3 )
    }

我已将 Spring Boot 更新为2.5.2从2.1.8.RELEASE. 在此之前，活性和就绪性探测都很好。现在，在更新 Spring Boot 后，我​​更新了我的应用程序属性文件：

management.endpoints.web.exposure.include=*
management.endpoints.jmx.exposure.include=health,info
management.endpoint.metrics.enabled=true
management.endpoint.prometheus.enabled=true
management.metrics.enable.*=true
management.metrics.enable.all=true
management.metrics.export.prometheus.enabled=true
management.metrics.use-global-registry=true




management.endpoint.health.probes.enabled=true
management.health.livenessstate.enabled=true
management.health.readinessstate.enabled=true
management.endpoint.health.show-details=always

我已分别向某些文档添加了最后 4 行。

在本地启动项目并从浏览器检查后：

http://localhost:8090/actuator/health/liveness给出{"status":"UP"}

但 http://localhost:8090/actuator/health/readiness给出{"status":"OUT_OF_SERVICE"}的是 503 状态。

{
    "status": "OUT_OF_SERVICE",
    "components": {
        "diskSpace": {
            "status": "UP",
            "details": {
                "total": 499963174912,
                "free": 326313852928,
                "threshold": 10485760,
                "exists": true
            }
        },
        "livenessState": {
            "status": "UP"
        },
        "ping": {
            "status": "UP"
        },
        "readinessState": {
            "status": "OUT_OF_SERVICE"
        }
    },
    "groups": [
        "liveness",
        "readiness"
    ] …

我正在使用自定义titleView并将其分配给navigationItem titleView.在iOS 11之前它一直运行良好.由于更新它的位置错误地放在中心位置,因为它原来是在更左边.除此之外,用户交互无效.

titleView = Bundle.main.loadNibNamed("SomeNib", owner: self, options: nil)?.first as? SomeNib
navigationItem.titleView = titleView

titleView只是一个通常的笔尖.

然后启用互动:

if let titleView = self.navigationItem.titleView {
            let tap = UITapGestureRecognizer(target: self, action: #selector(onTitleViewTap))
            titleView.addGestureRecognizer(tap)
            titleView.isUserInteractionEnabled = true
        }

我以这种方式采用mRGBA下的当前帧:

mRgba = inputFrame.rgba();

然后创建一个矩形对象,它取当前相机框架的高度和宽度

rect = new Rect();
rect.width = mRgba.width();
rect.height = mRgba.height();

它需要整个框架的空间,但当我试图收缩这个矩形时,它在一侧收缩(不是我需要的整体)

所以我试图找到矩形中心,然后尝试根据该中心和预定义的大小创建另一个矩形

int x = (int) (rect.tl().x + rect.br().x)/2;
int y = (int) (rect.tl().y + rect.br().y)/2;

Rect rect1 = new Rect(x,y,280,280);

Imgproc.rectangle(mRgba, rect1.tl(), rect1.br(), new Scalar(255, 0, 0), 2, 8, 0);

但它不在中心!! 我不确定矩形对象采取的参数我没有找到opencv的文件非常有用.那么如何克服这种情况我希望矩形正好位于相机框架的中心.
