一、问题描述

• 流程在部署的时候调用服务RepositoryService，该服务通过createDeployment，创建了一个DeploymentBuilder，由builder的deploy，问题代码如下：

 inputStream=new FileInputStream(new File(filePath));
 DeploymentBuilder deploymentBuilder =  repositoryService.createDeployment().name("TEST_FLOW")
        .addInputStream("flowname",inputStream);

 Deployment deployment= deploymentBuilder.deploy();

用后查看部署信息表ACT_RE_DEPLOYMENT有内容，如下图:

查询ACT_RE_PROCDEF表发现没有内容:

二、问题定位

跟踪代码进入类ParsedDeploymentBuilder，build函数如下：

public ParsedDeployment build() {
        List<ProcessDefinitionEntity> processDefinitions = new ArrayList();
        Map<ProcessDefinitionEntity, BpmnParse> processDefinitionsToBpmnParseMap = new LinkedHashMap();
        Map<ProcessDefinitionEntity, EngineResource> processDefinitionsToResourceMap = new LinkedHashMap();
        DeploymentEntity deploymentEntity = (DeploymentEntity)this.deployment;
        Iterator var5 = deploymentEntity.getResources().values().iterator();

        while(true) {
            EngineResource resource;
            do {
                if (!var5.hasNext()) {
                    return new ParsedDeployment(deploymentEntity, processDefinitions, processDefinitionsToBpmnParseMap, processDefinitionsToResourceMap);
                }

                resource = (EngineResource)var5.next();
            } while(!this.isBpmnResource(resource.getName()));

            LOGGER.debug("Processing BPMN resource {}", resource.getName());
            BpmnParse parse = this.createBpmnParseFromResource(resource);
            Iterator var8 = parse.getProcessDefinitions().iterator();

            while(var8.hasNext()) {
                ProcessDefinitionEntity processDefinition = (ProcessDefinitionEntity)var8.next();
                processDefinitions.add(processDefinition);
                processDefinitionsToBpmnParseMap.put(processDefinition, parse);
                processDefinitionsToResourceMap.put(processDefinition, resource);
            }
        }
    }

看到调用了this.isBpmnResource(resource.getName())，我们输入的名字会进行校验，校验函数如下:

protected boolean isBpmnResource(String resourceName) {
        String[] var2 = ResourceNameUtil.BPMN_RESOURCE_SUFFIXES;
        int var3 = var2.length;

        for(int var4 = 0; var4 < var3; ++var4) {
            String suffix = var2[var4];
            if (resourceName.endsWith(suffix)) {
                return true;
            }
        }

        return false;
    }

其中资源后缀的定义如下:

 public static final String[] BPMN_RESOURCE_SUFFIXES = new String[]{"bpmn20.xml", "bpmn"};

三、解决方案

调整资源名以bpmn或者bpmn20.xml结尾。调整如下:

repositoryService.createDeployment().name("TEST_FLOW")
        .addInputStream("flowname.bpmn20.xml",inputStream);

四、验证结果

修改后重新调用，验证结果如下：
