FormService简介：
formService主要是用来在流程中处理表单内容的，在学习formService之后，发现启动方式除了调用runtimeService中的startProcessInstanceById 或者startProcessInstanceBykey等方法紫外还有formService的方法如下：
//通过form服务启动
Map<String, String> properties = Maps.newHashMap();
properties.put("message", "this is my test message");
ProcessInstance processInstance = formService.submitStartFormData(processDefinition.getId(), properties);
完成方法也不止有complete这一种了，还有下面这种方法：
Map<String, String> properties1 = Maps.newHashMap();
properties1.put("yesOrNo", "yes");
formService.submitTaskFormData(task.getId(), properties1);
Task task1 = activitiRule.getTaskService().createTaskQuery().taskId(task.getId()).singleResult();
LOGGER.info("task1 = {}", task1);
完整测试的xml和代码如下：

测试类:
@Test
@Deployment(resources = {"my-process-form.bpmn20.xml"})
public void testFormService() {
FormService formService = activitiRule.getFormService();
ProcessDefinition processDefinition = activitiRule.getRepositoryService().createProcessDefinitionQuery().singleResult();
String startFormKey = formService.getStartFormKey(processDefinition.getId());
LOGGER.info("startFormKey = {}", startFormKey);
StartFormData startFormData = formService.getStartFormData(processDefinition.getId());
List<FormProperty> formProperties = startFormData.getFormProperties();
formProperties.forEach(form -> {
LOGGER.info("startFormKey = {}", ToStringBuilder.reflectionToString(startFormData, ToStringStyle.JSON_STYLE));
});
//通过form服务启动
Map<String, String> properties = Maps.newHashMap();
properties.put("message", "this is my test message");
ProcessInstance processInstance = formService.submitStartFormData(processDefinition.getId(), properties);
Task task = activitiRule.getTaskService().createTaskQuery().singleResult();
//流程启动才会确定taskId
TaskFormData taskFormData = formService.getTaskFormData(task.getId());
List<FormProperty> formProperties1 = taskFormData.getFormProperties();
formProperties1.forEach(formProperty -> {
LOGGER.info("formProperty = {}", ToStringBuilder.reflectionToString(formProperty, ToStringStyle.JSON_STYLE));
});
Map<String, String> properties1 = Maps.newHashMap();
properties1.put("yesOrNo", "yes");
formService.submitTaskFormData(task.getId(), properties1);
Task task1 = activitiRule.getTaskService().createTaskQuery().taskId(task.getId()).singleResult();
LOGGER.info("task1 = {}", task1);
}
