流程引擎之Camunda开发记录（六）流程部署的四种方法

第一种 文件方式部署

                Deployment deployment = repositoryService.createDeployment()
                .name("部署名称")
                .addClasspathResource(filePath + fileName + ".bpmn")
                .addClasspathResource("processes/images/" +  fileName + ".svg")
                .deploy();

filePath是相对于resources的相对路径

第二种 文件流方式部署

1.以下这种写法亲试有效

        String bpmnName = "collection_management_v1.bpmn";
        ClassPathResource classPathResource = new ClassPathResource("processes/collection_management_v1.bpmn");
        // 读取资源作为一个输入流
        InputStream bpmnfileInputStream = classPathResource.getInputStream();
        Deployment deployment = repositoryService .createDeployment()
                .name("部署名称")
                .addInputStream(bpmnName,bpmnfileInputStream)
                .deploy();//完成部署

2.以下报错提示找不到文件，解决方法暂时还没找到

        //获取资源相对路径
        String bpmnPath = "process/executeSolutionApproval.bpmn";
        String bpmnName = "executeSolutionApproval.bpmn";
        String pngPath = "process/executeSolutionApproval.png";
        String pngName = "executeSolutionApproval.png";

        //读取资源作为一个输入流
        FileInputStream bpmnfileInputStream = new FileInputStream(bpmnPath);
        FileInputStream pngfileInputStream = new FileInputStream(pngPath);
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        Deployment deployment = repositoryService .createDeployment()//创建部署对象
                .addInputStream(bpmnName,bpmnfileInputStream)
                .addInputStream(pngName, pngfileInputStream)
                .deploy();//完成部署

第三种 字符串方式部署

        //字符串
        String text = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><definitions>...</definitions>";

        Deployment deployment = processEngine.getRepositoryService()//获取流程定义和部署对象相关的Service
                .createDeployment()//创建部署对象
                .addString("helloworld.bpmn",text)
                .deploy();//完成部署

第四种 压缩包方式部署

        //从classpath路径下读取资源文件
        InputStream in = this.getClass().getClassLoader().getResourceAsStream("diagrams/helloworld.zip");
        ZipInputStream zipInputStream = new ZipInputStream(in);
        Deployment deployment = processEngine.getRepositoryService()//获取流程定义和部署对象相关的Service
                .createDeployment()//创建部署对象
                .addZipInputStream(zipInputStream)//使用zip方式部署，将helloworld.bpmn和helloworld.png压缩成zip格式的文件
                .deploy();//完成部署
