activiti流程----变量设置与获取

流程的变量有多重方式进行设置与获取

---

1：流程图以及属性配置

---

---

2：发布流程并开始

---

 /**
     * setValiable 与 setLocalValiable作用域不同
     */
    @Test
    public void deploeyFlow() {
        String folderPath = "study/activiti/diagrams/sequenceFlow";
        HashMap map = new HashMap<>();
        map.put("name", "连线流程");// 名称
        map.put("id", "sequenceFlow");// id
        map.put("category", "办公流程");// 类别
        activitiService.devlopActiviti(folderPath, map);

    }

    @Test
    public void startActiviti() {
        String processDefinitionKey = "sequenceFlow";
        String orgCode = "070067801";
        // 设置变量
        HashMap map = new HashMap<>();
        map.put("createLoginName", "0003");
        map.put("orgCode", orgCode);
        activitiService.startActiviti(processDefinitionKey, map);

    }

此时没有完成第一个任务。

3：设置变量并获取变量

---

@Test
    public void setVariable() {
        // String excutionId = "25001";
        String taskId = "10008";
        HashMap<String, Object> map = new HashMap<>();
        map.put("message", "重要");
        boolean isLocal = true;
        // activitiService.setVariableByExcutionId(excutionId, isLocal, map);
        activitiService.setVariableByTaskId(taskId, isLocal, map);

    }
    @Test
    public void getVariable() {
       // String excutionId = "10001";
        String taskId = "10008";
        Map<String, Object> map = new HashMap<>();

        boolean isLocal = false;
         //map = activitiService.getVariableByExcutionId(excutionId, isLocal );
        map = activitiService.getVariableByTaskId(taskId, isLocal);
        LOGGER.info("message【{}】",(String)map.get("message"));
        //SequenceFlow sequenceFlow = activitiService.getVariableByTaskId(taskId, "sequenceFlow", SequenceFlow.class);

       // LOGGER.info("创建时间【{}】", sequenceFlow.getDate());
    }
 @Override
    public boolean setVariableByTaskId(String taskId, boolean isLocal, HashMap<String, Object> map) {
        /*
         * taskService.setVariable(taskId, variableName, value);
         *
         * 设置本执行对象的变量，该作用域只在当前的executionId中 taskService.setVariableLocal(taskId,
         * variableName, value); 可以设置对个变量，放在map中
         */
        if (isLocal) {
            taskService.setVariablesLocal(taskId, map);
        } else {
            taskService.setVariables(taskId, map);
        }
        return true;
    }
  @Override
    public Map<String, Object> getVariableByTaskId(String taskId, boolean isLocal) {
        Map<String, Object> variablesMap = new HashMap<String, Object>();
        if (isLocal) {
            variablesMap = taskService.getVariablesLocal(taskId);
        } else {
            variablesMap = taskService.getVariables(taskId);
        }
        return variablesMap;
    }

日志：

---

[20:39:24:795] [INFO] - wsylp.log.MyLog.logAfter(MyLog.java:29) - @AfterReturning：wsylp.service.ActivitiService.getVariableByTaskId end.
[20:39:24:795] [INFO] - serviceTest.ActivitiVariableTest.getVariable(ActivitiVariableTest.java:172) - message【重要】

---

4：设置变量为对象

---

如果变量为对象需要实现序列化接口

public class SequenceFlow implements Serializable {

    private static final long serialVersionUID = -1164661902871465047L;
    private String message;//信息（重要，不重要）
    private String createLoginName;// 申请人
    private Date date;// 申请日期

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public String getCreateLoginName() {
        return createLoginName;
    }

    public void setCreateLoginName(String createLoginName) {
        this.createLoginName = createLoginName;
    }

    public Date getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }

}

设置变量

 /**
     * 设置流程变量值
     */
    @Test
    public void setVariablesByBean() {
        String taskId = "10008";

        /**
         * 支持的变量类型
         * 
         * 

         * 简单类型：String boolean Integer double date 

         * 自定义对象bean
         */
        // 传递的是一个自定义的bean对象
        SequenceFlow sequenceFlow = new SequenceFlow();
        sequenceFlow.setCreateLoginName("0003");
        sequenceFlow.setDate(new Date());
        sequenceFlow.setMessage("重要");
        activitiService.setVariableByTaskId(taskId, "sequenceFlow", sequenceFlow);

    }

    @Test
    public void getVariable() {
       // String excutionId = "10001";
        String taskId = "10008";
        Map map = new HashMap<>();

        boolean isLocal = false;
         //map = activitiService.getVariableByExcutionId(excutionId, isLocal );
       // map = activitiService.getVariableByTaskId(taskId, isLocal);
        //LOGGER.info("message【{}】",(String)map.get("message"));
        SequenceFlow sequenceFlow = activitiService.getVariableByTaskId(taskId, "sequenceFlow", SequenceFlow.class);

       LOGGER.info("创建时间【{}】", sequenceFlow.getDate());
    }

日志

---

[20:45:47:841] [INFO] - wsylp.log.MyLog.logAfter(MyLog.java:29) - @AfterReturning：wsylp.service.ActivitiService.getVariableByTaskId end.
[20:45:47:841] [INFO] - serviceTest.ActivitiVariableTest.getVariable(ActivitiVariableTest.java:175) - 创建时间【2018-06-17T20:45:24.240+0800】

由于此时串的message为重要，那么下一个审批人为总经理

---

5：完成任务并查询

---

由于变量设置在sequenceFlow上，尽量设置变量为全局的。或者设置在执行对象上。

[20:53:50:698] [INFO] - wsylp.service.impl.ActivitiServiceImpl.finshTask(ActivitiServiceImpl.java:148) - 完成任务【10008】
