Question

我尝试使用以下代码从文件部署流程定义

#import "ALISBNScanViewController.h"
#import <Anyline/Anyline.h>

NSString * const kISBNLicenseKey = Anyline_LICENSE_KEY;

@interface ALISBNScanViewController ()<AnylineOCRModuleDelegate>
// The Anyline module used for OCR
@property (nonatomic, strong) AnylineOCRModuleView *ocrModuleView;

@end

@implementation ALISBNScanViewController
/*
 We will do our main setup in viewDidLoad. Its called once the view controller is getting ready to be displayed.
 */
- (void)viewDidLoad {
    [super viewDidLoad];
    // Set the background color to black to have a nicer transition
    self.view.backgroundColor = [UIColor blackColor];
    self.title = @"Text Recognition";

    // Initializing the module. Its a UIView subclass. We set the frame to fill the whole screen
    CGRect frame = [[UIScreen mainScreen] applicationFrame];
    frame = CGRectMake(frame.origin.x, frame.origin.y + self.navigationController.navigationBar.frame.size.height, frame.size.width, frame.size.height - self.navigationController.navigationBar.frame.size.height);
    self.ocrModuleView = [[AnylineOCRModuleView alloc] initWithFrame:frame];

    ALOCRConfig *config = [[ALOCRConfig alloc] init];
    config.tesseractLanguages = @[@"eng_no_dict", @"deu"];
    config.charWhiteList = @"PMMDOBCPSKA1234_/ ";
    config.scanMode = ALAuto;

    NSError *error = nil;
    BOOL success = [self.ocrModuleView setupWithLicenseKey:kISBNLicenseKey delegate:self ocrConfig:config error:&error];
    if (!success) {
        NSAssert(success, @"Setup Error: %@", error.debugDescription);
    }

    NSString *confPath = [[NSBundle mainBundle] pathForResource:@"isbn_config" ofType:@"json"];
    ALUIConfiguration *isbnconf = [ALUIConfiguration cutoutConfigurationFromJsonFile:confPath];
    self.ocrModuleView.currentConfiguration = isbnconf;

    [self.view addSubview:self.ocrModuleView];    
}


-(void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    [self startAnyline];
}

/*
 Cancel scanning to allow the module to clean up
 */
- (void)viewWillDisappear:(BOOL)animated {
    [self.ocrModuleView cancelScanningAndReturnError:nil];
}

- (void)startAnyline {
    NSError *error;
    BOOL success = [self.ocrModuleView startScanningAndReturnError:&error];
    if( !success ) {
        NSAssert(success, @"Start Scanning Error: %@", error.debugDescription);
    }
}

#pragma mark -- AnylineOCRModuleDelegate

/*
 This is the main delegate method Anyline uses to report its results
 */
- (void)anylineOCRModuleView:(AnylineOCRModuleView *)anylineOCRModuleView
               didFindResult:(ALOCRResult *)result {
    NSString *label = result.result;

    DLog(@"LABEL:%@",label);


    NSString *message = [NSString stringWithFormat:@"Testo riconosciuto: %@",label];


    UIAlertController * alert = [UIAlertController alertControllerWithTitle:@"Testo riconosciuto" message:message preferredStyle:UIAlertControllerStyleAlert];
    UIAlertAction* okBtn = [UIAlertAction actionWithTitle:@"Ok" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {
        [alert dismissViewControllerAnimated:YES completion:nil];
        [self startAnyline];
    }];


    [alert addAction:okBtn];

    [self presentViewController:alert animated:YES completion:nil];
}

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
    NSError *error = nil;
    BOOL success = [self.ocrModuleView startScanningAndReturnError:&error];

    NSAssert(success, @"We failed starting: %@",error.debugDescription);
}

@end

上面的代码成功运行，并打印出新的deploymentId。

稍后，我尝试使用以下代码列出已部署的流程定义

    DeploymentBuilder deploymentBuilder = repositoryService.createDeployment().name(definitionName);
    deploymentBuilder.addInputStream(definitionName, definitionFileInputStream);
    String deploymentId = deploymentBuilder.deploy().getId();
    System.out.println(deploymentId);

以上代码成功运行，但输出始终为0.

我做了一些调查，发现在List<ProcessDefinition> definitions = repositoryService.createProcessDefinitionQuery().list(); System.out.println(definitions.size());表中存在一个带有相应ACT_GE_BYTEARRAY的条目，deploymentId列包含定义文件的内容。< / p>

我还发现在BYTES_表中找不到相应的条目。

有什么东西搞乱吗？从API和示例中我发现上面的代码似乎已经足够了，或者是否有缺失的步骤？

感谢您的帮助

Answer 1

事实证明，该问题与definitionName (thanks thorben!)有关，因为它必须以.bpmn20.xml或.bpmn结束。

进一步测试后，以下definitionName代码

需要后缀

    deploymentBuilder.addInputStream(definitionName, definitionFileInputStream);

离开以下definitionName没有后缀是没错的

    repositoryService.createDeployment().name(definitionName);

Answer 2

您似乎忘记了部署的流程定义上的isExecutable标志。请检查您的流程模型是否包含isExecutable标志。如果使用camunda建模器，只需在过程的属性面板中设置此选项。

如果使用非可执行定义调用#deploy()，则会创建部署，但由于流程定义不可执行，因此未部署流程定义。

在最新版本的camunda平台（7.7）上，DeploymentBuilder添加了一个名为#deployWithResult()的新方法。此方法返回已部署的流程定义，因此很容易检查是否已部署流程定义。

通过API进行Camunda流程定义部署
