一、动态表单

表单分类
Flowable提供了一种简单灵活的方式，用来为业务流程中的人工步骤添加表单。由俩种方式使用表单的方法：

使用（由表单设计器创建的）表单定义的内置表单渲染（弊端是每一步都要设计表单）。
外部表单渲染。使用外部表单渲染时，可以使用表单参数；也可以使用表单key定义，引用外部的、使用自定义的代码解析表单。

动态表单相较于流程变量的优点在于变量是零散的，而表单是完整的，整存整取。
在这里插入图片描述

案例

部署流程定义，启动流程实例

/**
 * 部署流程
 */
@Test
void test_deploy() {
    Deployment deploy = repositoryService.createDeployment()
            .name("ManualDeployment").deploy();
    System.out.println(deploy.getId());
}

/**
 * 启动流程
 */
@Test
void startFormFlow() throws Exception{
    ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery()
            .processDefinitionKey(PROC_KEY)
            .latestVersion()
            .singleResult();
    Map<String,String> map = new HashMap<>();
    map.put("day","1");
    map.put("startTime","2023-01-29 21:03");
    map.put("reason","去看电影《深海》");
    ProcessInstance processInstance = formService.submitStartFormData(processDefinition.getId(), map);
    System.out.println("processInstance.getProcessInstanceId() = " + processInstance.getProcessInstanceId());
}

获取表单字段

/**
* 获取表单字段
*/
@Test
public void getStartFromData() {
   ProcessDefinition processDefinition = repositoryService
           .createProcessDefinitionQuery()
           .processDefinitionKey(PROC_KEY)
           .latestVersion()
           .singleResult();
   StartFormData startFormData = formService.getStartFormData(processDefinition.getId());
   List<FormProperty> formProperties = startFormData.getFormProperties();
   for (FormProperty formProperty : formProperties) {
       String id = formProperty.getId();
       String name = formProperty.getName();
       FormType type = formProperty.getType();
       System.out.println("id = " + id);
       System.out.println("name = " + name);
       System.out.println("type.getClass() = " + type.getClass());
   }
}

表单信息修改保存与查询

/**
 * 保存表单，并查询表单
 */
@Test
void saveAndQueryFormData() {
    Task task = taskService.createTaskQuery()
            .processDefinitionKey(PROC_KEY)
            .singleResult();
    Map<String, String> map = new HashMap<>();
    map.put("day", "3");
    map.put("startTime", "2023-01-27 22:42");
    map.put("reason", "测试以下提交流程");
    formService.saveFormData(task.getId(), map);
    TaskFormData taskFormData = formService.getTaskFormData(task.getId());
    List<FormProperty> formProperties = taskFormData.getFormProperties();
    for (FormProperty formProperty : formProperties) {
        System.out.println("formProperty.getId() = " + formProperty.getId());
        System.out.println("formProperty.getName() = " + formProperty.getName());
        System.out.println("formProperty.getValue() = " + formProperty.getValue());
    }
}

完成任务

@Test
void completeTask() {
    List<Task> tasks = taskService.createTaskQuery()
            .processDefinitionKey(PROC_KEY)
            .orderByTaskCreateTime().desc().list();
    Task task = tasks.get(0);
    System.out.println(task.getAssignee() + "-完成任务-" + task.getId());
    Map<String, String> map = new HashMap<>();
    map.put("day", "4");
    map.put("startTime", "2023-01-30 22:42");
    map.put("reason", "一起去看《深海》吧");
    formService.submitTaskFormData(task.getId(), map);
}

二、外置表单

1. json表单

集成SpringBoot的Flowable提供了.form的自动部署机制。会对保存在forms文件夹下的表单自动部署。

1.1 配置表单位置和表单后缀名

flowable:
  form:
    resource-suffixes: "**.form"    # 默认的表单⽂件后缀
    resource-location: "classpath*:/forms"    # 默认的表单⽂件位置

1.2 创建form表单

{
    "key": "qjlc_form.form",
    "name": "经理审批表单",
    "fields": [
        {
            "id": "days",
            "name": "请假天数",
            "type": "string",
            "required": true,
            "placeholder": "empty"
        },
        {
            "id": "reason",
            "name": "请假原因",
            "type": "string",
            "required": true,
            "placeholder": "empty"
        },
        {
            "id": "startTime",
            "name": "开始时间",
            "type": "date",
            "required": true,
            "placeholder": "empty"
        }
    ]
}

1.3 绘制流程

1.4 测试案例

部署流程与表单信息

@Test
void test_deploy() {
    Deployment deploy = repositoryService.createDeployment()
            .category("qjcl-table类型")
            .key("qjlc-json")
            .addClasspathResource("process/请假流程-json表单.bpmn20.xml")
            .name("ManualDeploy-" + PROC_KEY + new Date()).deploy();
    FormDeployment formDeployment = formRepositoryService.createDeployment()
            .addClasspathResource("forms/application_form.form")
            .name("外置表单-" + PROC_KEY)
            .parentDeploymentId(deploy.getId())
            .category("qjcl-table类型")
            .deploy();
    System.out.println("deploy.getId() = " + deploy.getId());
    System.out.println("formDeployment.getId() = " + formDeployment.getId());
}

2. 启动流程

@Test
void startFlow() {
    ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery()
            .processDefinitionKey(PROC_KEY)
            .latestVersion().singleResult();
    Map<String, Object> params = this.buildParams(3, "出去玩");
    ProcessInstance processInstance = runtimeService.startProcessInstanceWithForm(processDefinition.getId(), "请假开始",
            params
            , processDefinition.getName());
    System.out.println("processInstance.getId() = " + processInstance.getId());
}

获取表单信息

@Test
void getFormFields() {
    ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery()
            .processDefinitionKey(PROC_KEY)
            .latestVersion().singleResult();
    Task task = taskService.createTaskQuery()
            .processDefinitionId(processDefinition.getId())
            .singleResult();
    FormInfo formInfo = taskService.getTaskFormModel(task.getId());
    System.out.println("formInfo.getId() = " + formInfo.getId());
    SimpleFormModel formModel = (SimpleFormModel) formInfo.getFormModel();
    List<FormField> fields = formModel.getFields();
    fields.forEach(e -> {
        System.out.println("===================================");
        System.out.println("e.getId() = " + e.getId());
        System.out.println("e.getName() = " + e.getName());
        System.out.println("e.getType() = " + e.getType());
        System.out.println("e.getValue() = " + e.getValue());
    });
}

完成任务

@Test
void complete() {
    ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery()
            .processDefinitionKey(PROC_KEY)
            .latestVersion().singleResult();
    Task task = taskService.createTaskQuery()
            .processDefinitionId(processDefinition.getId())
            .singleResult();
    FormInfo formInfo = taskService.getTaskFormModel(task.getId());
    Map<String, Object> params = this.buildParams(6, "go home");
    taskService.completeTaskWithForm(task.getId(),
            formInfo.getId()
            , "请假处理中",
            params);
    System.out.println(task.getAssignee() + " 处理完成 task.getId() = " + task.getId());
}
/**
 * 保存表单与完成任务
 */
@Test
void complete2() {
    ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery()
            .processDefinitionKey(PROC_KEY)
            .latestVersion().singleResult();
    Task task = taskService.createTaskQuery()
            .processDefinitionId(processDefinition.getId())
            .singleResult();
    FormInfo formInfo = taskService.getTaskFormModel(task.getId());
    Map<String, String> params = new HashMap<>();
    params.put("days", "20");
    params.put("reason", "happy year");
    Map<String, Object> vars = new HashMap<>();
    vars.put("op", true);

    formService.saveFormData(task.getId(), params);
    taskService.complete(task.getId(), vars);
    System.out.println(task.getAssignee() + " 处理完成 task.getId() = " + task.getId());
}

查询历史表单信息

@Test
void getHiFormFields() {
    ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery()
            .processDefinitionKey(PROC_KEY)
            .latestVersion().singleResult();
    List<HistoricTaskInstance> list = historyService.createHistoricTaskInstanceQuery()
            .processDefinitionId(processDefinition.getId())
            .list();
    list.forEach(hti -> {
        System.out.println("hti.getExecutionId() = " + hti.getId());
        FormInfo formInfo = taskService.getTaskFormModel(hti.getId());
        System.out.println("formInfo = " + formInfo);
        if (formInfo != null) {
            SimpleFormModel formModel = (SimpleFormModel) formInfo.getFormModel();
            List<FormField> fields = formModel.getFields();
            fields.forEach(e -> System.out.println(e.getName() + " : " + e.getType() + " : " + e.getValue()));
        }
        System.out.println("===================================");
    });
}

2. html表单

2.2 创建html表单

leave_form.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<form action="">
    <table>
        <tr>
            <td>请假天数：</td>

</html>

2.3 测试案例

部署流程

@Test
void deploy() {
    DeploymentBuilder builder = repositoryService.createDeployment()
            .category("HX-FORM-TYPE")
            .name("HTML-FORM")
            .key(PROC_KEY)
            .addClasspathResource("process/请假流程-html表单.bpmn20.xml");

    InputStream is = this.getClass().getClassLoader().getResourceAsStream("templates/leave_form.html");
    // 注意！这里必须指定名称与流程定义的名称相同！否则将会报错
    // Form with formKey 'xxx.html' does not exist
    builder.addInputStream("leave_form.html", is);
    is = this.getClass().getClassLoader().getResourceAsStream("templates/approval.html");
    builder.addInputStream("approval.html", is);
    Deployment deployment = builder.deploy();
    System.out.println("deployment.getId() = " + deployment.getId());
}

获取表单信息

@Test
void getStartFormContent() {
    ProcessDefinition pd = repositoryService.createProcessDefinitionQuery()
            .latestVersion().processDefinitionKey(PROC_KEY).singleResult();
    System.out.println("pd = " + pd);
    String startFormKey = formService.getStartFormKey(pd.getId());
    System.out.println("startFormKey = " + startFormKey);
    String renderedStartForm = (String) formService.getRenderedStartForm(pd.getId());
    System.out.println("renderedStartForm = " + renderedStartForm);
} 

@Test
void getFormContent2() throws IOException {
    ProcessDefinition pd = repositoryService.createProcessDefinitionQuery()
            .latestVersion().processDefinitionKey(PROC_KEY).singleResult();
    List<String> deploymentResourceNames = repositoryService.getDeploymentResourceNames(pd.getDeploymentId());
    byte[] bt = new byte[1024];
    for (String name : deploymentResourceNames) {
        System.out.println("deploymentResourceName = " + name);
        InputStream is = repositoryService.getResourceAsStream(pd.getDeploymentId(), name);
        while (is.read(bt) != -1) {
            System.out.print(new String(bt, 0, bt.length));
        }
    }
}

启动流程

@Test
void startFlow() {
    ProcessDefinition pd = repositoryService.createProcessDefinitionQuery()
            .processDefinitionKey(PROC_KEY)
            .latestVersion().singleResult();
    Map<String, String> vars = new HashMap<>();
    vars.put("days", "3");
    vars.put("reason", "去看《深海》");
    vars.put("startTime", new Date().toString());
    ProcessInstance pi = formService.submitStartFormData(pd.getId(), vars);
    System.out.println("pi.getId() = " + pi.getId());
}

完成任务

@Test
void completeTask1() {
    ProcessDefinition pd = repositoryService.createProcessDefinitionQuery()
            .processDefinitionKey(PROC_KEY).latestVersion().singleResult();
    Task task = taskService.createTaskQuery()
            .taskCandidateOrAssigned("whx")
            .processDefinitionId(pd.getId()).singleResult();
    Map<String, String> vars = new HashMap<>();
    vars.put("days", "2");
    vars.put("reason", "去看《深海》吧");
    vars.put("startTime", new Date().toString());
    formService.submitTaskFormData(task.getId(), vars);
}

获取任务表单信息

@Test
void getTaskFormContent() {
    ProcessDefinition pd = repositoryService.createProcessDefinitionQuery()
            .processDefinitionKey(PROC_KEY).latestVersion().singleResult();
    Task task = taskService.createTaskQuery()
            .taskCandidateOrAssigned("dy")
            .processDefinitionId(pd.getId()).singleResult();
    String renderedTaskForm = (String) formService.getRenderedTaskForm(task.getId());
    System.out.println("renderedTaskForm = " + renderedTaskForm);
}

2.4 踩坑记录 FlowableObjectNotFoundException: Form with formKey ‘leave_form.html’ does not exist

注意！这里必须指定名称与流程定义的名称相同！否则将会报错 FlowableObjectNotFoundException: Form with formKey 'leave_form.html' does not exist
正确示例：指定表单的名称与流程定义文件中的一致。

InputStream is = this.getClass().getClassLoader().getResourceAsStream("templates/leave_form.html");
builder.addInputStream("leave_form.html", is);
is = this.getClass().getClassLoader().getResourceAsStream("templates/approval.html");
builder.addInputStream("approval.html", is);
Deployment deployment = builder.deploy();

错误示例：未指定表单的名称。

Deployment deploy = repositoryService.createDeployment()
       .addClasspathResource("process/请假流程-html表单.bpmn20.xml")
       .addClasspathResource("templates/leave_form.html")
       .addClasspathResource("templates/approval.html")
       .category(PROC_KEY)
       .name("ManualDeploy" + new Date())
       .key(PROC_KEY).deploy();

三、任务回退

1. 串行任务回退

在这里插入图片描述

2. 并行任务回退

并行任务中的一个审批人员驳回到提交节点，后续提交的同样回要求并行中的所有人审批。
示例流程图与子流程回退一起。

3. 子流程回退

子流程回退，也是同样的步骤。
在这里插入图片描述

案例代码：

private final String PROC_KEY = "back-child-proc";

@Test
void deploy() {
    Deployment deployment = repositoryService.createDeployment()
            .name("MunualDeploy-" + new Date()).deploy();
    System.out.println("deployment.getId() = " + deployment.getId());
    System.out.println("deployment.getName() = " + deployment.getName());
}

@Test
void startFlow() {
    ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(PROC_KEY);
    System.out.println("processInstance.getId() = " + processInstance.getId());
}

/**
 * 发起申报
 */
@Test
void completeTask() {
    Task task = taskService.createTaskQuery()
            .processDefinitionKey(PROC_KEY)
            .taskCandidateOrAssigned("huathy")
            .singleResult();
    Map<String, Object> params = new HashMap<>();
    params.put("num", 5);
    taskService.complete(task.getId(), params);
    System.out.println(task.getAssignee() + "-完成任务-" + task.getName() + task.getId());
}
@Test
void completeTask2() {
    Task task = taskService.createTaskQuery()
            .processDefinitionKey(PROC_KEY)
            .taskCandidateOrAssigned("u1")
            .singleResult();
    taskService.complete(task.getId());
    System.out.println(task.getAssignee() + "-完成任务-" + task.getName() + task.getId());
}

/**
 * 转派、回退
 */
@Test
void task_back(){
    Task task = taskService.createTaskQuery().processDefinitionKey(PROC_KEY)
            .taskCandidateOrAssigned("dy").singleResult();
    runtimeService.createChangeActivityStateBuilder()
            .processInstanceId(task.getProcessInstanceId())
            .moveActivityIdTo(task.getTaskDefinitionKey(),"a2")
            .changeState();
    System.out.println("回退成功");
}

测试步骤：

tjsq -> a1 -> a2 -> boss-sp[驳回a2] -> a2[驳回tjsq] -> tjsq
tjsq -> b1 -> b2[审批通过]、b3[驳回tjsq]
