Question

我们将构建一个工作流管理系统，我们将camunda引擎Rest API嵌入到Rest应用程序中。

现在我的库存定义如下：

public class Inventory {
    private String objectName;
    private int objectCount;

    // getters and setters
}

这是一个示例工作流程：

我最终会有一个html表单，它会提交这样的内容：

{ 
    "inventories" : [{"name": "banana","count": 3},{"name":"orange","count": 4}]
}

我想将此内容提交到/ task / {id} / submit-form，但我不知道要输入什么类型。

我尝试将模型中的类型设置为List<org.example.Inventory>，但是在部署流程定义时，其余的api会抛出异常：

org.camunda.bpm.engine.ProcessEngineException：ENGINE-09005无法解析BPMN流程。错误： *未知类型'列表'| org.example / PM.bpmn |第65行|第90栏

我也见过this示例，但我只使用Rest API而不是整个bpm平台（此外我们更喜欢使用纯html表单）。

那怎么办？我应该把什么类型放入？

我的camunda.cfg.xml：

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id="processEngineConfiguration" class="org.camunda.bpm.engine.impl.cfg.StandaloneProcessEngineConfiguration">

        <property name="jdbcUrl" value="jdbc:h2:mem:activiti;DB_CLOSE_DELAY=1000" />
        <property name="jdbcDriver" value="org.h2.Driver" />
        <property name="jdbcUsername" value="sa" />
        <property name="jdbcPassword" value="" />

        <property name="databaseSchemaUpdate" value="true" />
    </bean>

</beans>

我的processsengine提供者：

public class MyProcessEngineProvider implements ProcessEngineProvider {
    @Override
    public ProcessEngine getDefaultProcessEngine() {
        ProcessEngine engine = ProcessEngines.getDefaultProcessEngine();
        RepositoryService repositoryService = engine.getRepositoryService();
        repositoryService.createDeployment()
                .addClasspathResource("org.newtech/PM.bpmn")
                .deploy();            
        return engine;
    }

    @Override
    public ProcessEngine getProcessEngine(String s) {
        return getDefaultProcessEngine();
    }

    @Override
    public Set<String> getProcessEngineNames() {
        Set<String> names = new HashSet<>(1);
        names.add("default");
        return names;
    }
}

如何为camunda rest api创建List <inventory>类型的表单字段
