我这里是集成在springboot中使用

新建表单：

在forms文件夹下新建test.form文件

{
"key": "form1",
"name": "请假流程",
"fields": [
            {
            "id": "startTime",
            "name": "开始时间",
            "type": "date",
            "required": true,
            "placeholder": "empty"

            },
            {
            "id": "endTime",
            "name": "结束时间",
            "type": "date",
            "required": true,
            "placeholder": "empty"
            },
            {
            "id": "reason",
            "name": "请假原因",
            "type": "text",
            "required": true,
            "placeholder": "empty"
            }
    ]
}

建立流程图

在processes文件夹下新建流程NewProcess.bpmn

使用eclipse插件绘制

流程id为newProcess，设置每个节点的Form Key为form1 流程图如下：

流程中排他网关后分支配置如下：

自动生成的XML代码如下

带参数启动流程方法：

    @Transactional
    public void startProcessUser() {
    	//设置当前线程用户ID
    	String id = "fed56399-c419-4e8a-8c7b-664bc9d0144b";
    	//注意一点:这个方法最终使用一个ThreadLocal类型的变量进行存储，也就是与当前的线程绑定，所以流程实例启动完毕之后，需要设置为null，防止多线程的时候出问题。
    	Authentication.setAuthenticatedUserId(id);
    	//带参数开始流程
    	Map<String, Object> formProperties;
        formProperties = new HashMap<>();
        formProperties.put("reason", "家里有事");
        formProperties.put("startTime", "2018");
        formProperties.put("endTime", "2018");
        //启动流程
        ProcessInstance pi = runtimeService.startProcessInstanceByKey("newProcess", formProperties);
        log.info("id:" + pi.getId());
//    	Authentication.setAuthenticatedUserId(null);
        //查询第一个任务
        Task task = taskService.createTaskQuery().taskAssignee(Authentication.getAuthenticatedUserId()).singleResult();
        Map<String, Object> info = taskService.getVariables(task.getId());
        log.info("请假原因：" + info.get("reason"));
        taskService.complete(task.getId());
        //查询第二个任务(未指定人查询所有)
        task = taskService.createTaskQuery().singleResult();
        log.info("taskID:" + task.getName());
        //完成任务
        taskService.complete(task.getId());
    }

绑定表单启动流程方法：

    @Transactional
    public void startProcessFrom() {
    	String id = "fed56399-c419-4e8a-8c7b-664bc9d0144b";
    	Authentication.setAuthenticatedUserId(id);
    	ProcessInstance pi = runtimeService.startProcessInstanceByKey("newProcess");
    	log.info("id:" + pi.getId());
    	Task task = taskService.createTaskQuery().taskAssignee(Authentication.getAuthenticatedUserId()).singleResult();
    	log.info("流程中表单ID ：" + task.getFormKey());
    	//获取个人任务表单
        FormInfo taskFM = taskService.getTaskFormModel(task.getId());
        SimpleFormModel fm = new SimpleFormModel();
        FormModel fmModel = taskFM.getFormModel();
        fm = (SimpleFormModel)fmModel;
        List<FormField> fields = fm.listAllFields();
        for(FormField ff:fields) {
        	log.info(ff.getId());
        	log.info(ff.getName());
        	log.info(ff.getValue() + "");
        }
    	//带表单流程
    	String outcome = "";
    	Map<String, Object> formProperties;
        formProperties = new HashMap<>();
        formProperties.put("reason", "家里有事");
        formProperties.put("startTime", "2018");
        formProperties.put("endTime", "2018");
        Map<String, Object> transientVariables = new HashMap<String, Object>(1);
        transientVariables.put("money", "190");
        taskService.completeTaskWithForm(task.getId(), taskFM.getId(), outcome, formProperties, transientVariables);
        //查询第二个任务(未指定人查询所有)
        task = taskService.createTaskQuery().singleResult();
        FormInfo fm2 = taskService.getTaskFormModel(task.getId());
        log.info(fm2.getKey());
        fmModel = fm2.getFormModel();
        fm = (SimpleFormModel)fmModel;
        fields = fm.listAllFields();
        for(FormField ff:fields) {
        	log.info(ff.getId());
        	log.info(ff.getName());
        	log.info(ff.getValue() + "");
        }
        //完成任务
        taskService.complete(task.getId());
    }

创建用户方法：

    /**
     * 创建用户
     * @param firstName
     * @param lastName
     * @param password
     * @param email
     * LianZheng-3130002311@qq.com
     * 2019年1月21日 下午5:35:27
     */
    @Transactional
    public void createUser(String firstName, String lastName, String password, String email) {
    	//生成ID
    	String id = UUID.randomUUID().toString();
    	User user = idmIdentityService.newUser(id);
    	user.setFirstName(firstName);
    	user.setLastName(lastName);
    	user.setPassword(password);
    	user.setEmail(email);
    	idmIdentityService.saveUser(user);
    	//根据id查询
    	user = idmIdentityService.createUserQuery().userId(id).singleResult();
    	log.info("创建成功 用户名：" + user.getLastName());
    	//设置当前线程用户ID
    	idmIdentityService.setAuthenticatedUserId(id);
    }
