JBoss 系列九十九：Rest WebService jBPM 6 集成示例

标签：jboss bpm suite 6   jboss   bpm   

概述

jBPM 6 提供 Rest API 供第三方应用整合使用 jBPM 6，本文演示如果通过 Rest API：

• 启动流程
• 获取流程实例信息
• 启动 User Task
• 完成 User Task

本文所使用的流程如下

如上流程只有一个 User Task 节点，User Task 执行开始和执行结束都输出相关提示。流程 ID为 org.brms.test，节点名字为 Test，执行节点需要的 userID 为 kylin，角色为 IT。

为方便观察，我们需要 jBPM 6 使用 Mysql 替换默认的 H2 数据库。

启动流程

启动流程 Rest API 如下：

/runtime/{id: [a-zA-Z0-9-:\\.]+}")/process/{id: [a-zA-Z0-9-:\\.]+}/start

mysql> select id, duration, start_date, end_date, processId, processInstanceId, processName, status from ProcessInstanceLog;
+----+----------+---------------------+---------------------+---------------+-------------------+-------------+--------+
| id | duration | start_date          | end_date            | processId     | processInstanceId | processName | status |
+----+----------+---------------------+---------------------+---------------+-------------------+-------------+--------+
|  1 |    51569 | 2014-05-10 21:17:20 | 2014-05-10 21:18:11 | org.brms.test |                 1 | test        |      2 |
|  2 |  3770025 | 2014-05-10 21:24:57 | 2014-05-10 22:27:47 | org.brms.test |                 2 | test        |      2 |
|  3 |  4060507 | 2014-05-10 21:25:33 | 2014-05-10 22:33:13 | org.brms.test |                 3 | test        |      2 |
|  4 |  2620216 | 2014-05-10 21:49:41 | 2014-05-10 22:33:21 | org.brms.test |                 4 | test        |      2 |
|  5 |  2561315 | 2014-05-10 21:50:49 | 2014-05-10 22:33:30 | org.brms.test |                 5 | test        |      2 |
|  6 |  2557182 | 2014-05-10 21:51:01 | 2014-05-10 22:33:38 | org.brms.test |                 6 | test        |      2 |
|  7 |  2558504 | 2014-05-10 21:51:07 | 2014-05-10 22:33:45 | org.brms.test |                 7 | test        |      2 |
|  8 |     NULL | 2014-05-11 13:21:05 | NULL                | org.brms.test |                 1 | test        |      1 |
+----+----------+---------------------+---------------------+---------------+-------------------+-------------+--------+

获取流程实例

获取流程实例 Rest API 如下：

/runtime/{id: [a-zA-Z0-9-:\\.]+}")/process/instance/{id: [0-9]+}

ProcessInstance 1 [processId=org.brms.test,state=1]

http://localhost:8080/business-central/rest/runtime/org.kie.example:project1:1.0.0-SNAPSHOT/process/instance/1

开始 User Task

开始 User Task Rest API 如下：

/task/execute{id: \\d+}/start

mysql> select id, createdOn, deploymentId, processInstanceId, processId, status, createdBy_id from Task;
+----+---------------------+-----------------------------------------+-------------------+---------------+----------+--------------+
| id | createdOn           | deploymentId                            | processInstanceId | processId     | status   | createdBy_id |
+----+---------------------+-----------------------------------------+-------------------+---------------+----------+--------------+
|  1 | 2014-05-11 13:21:05 | org.kie.example:project1:1.0.0-SNAPSHOT |                 1 | org.brms.test | Reserved | kylin        |
+----+---------------------+-----------------------------------------+-------------------+---------------+----------+--------------+

运行 RestEasyClientTaskStart.java 开始执行 User Task ，执行之后我们同样到数据库查看当前 User Task  的信息：

mysql> select id, createdOn, deploymentId, processInstanceId, processId, status, createdBy_id from Task;
+----+---------------------+-----------------------------------------+-------------------+---------------+------------+--------------+
| id | createdOn           | deploymentId                            | processInstanceId | processId     | status     | createdBy_id |
+----+---------------------+-----------------------------------------+-------------------+---------------+------------+--------------+
|  1 | 2014-05-11 13:21:05 | org.kie.example:project1:1.0.0-SNAPSHOT |                 1 | org.brms.test | InProgress | kylin        |
+----+---------------------+-----------------------------------------+-------------------+---------------+------------+--------------+

完成User Task

完成User Task Rest API 如下：

/task/execute{id: \\d+}/complete

mysql> select id, createdOn, deploymentId, processInstanceId, processId, status, createdBy_id from Task;
Empty set (0.00 sec)

mysql> select id, duration, start_date, end_date, processId, processInstanceId, processName, status from ProcessInstanceLog;
+----+----------+---------------------+---------------------+---------------+-------------------+-------------+--------+
| id | duration | start_date          | end_date            | processId     | processInstanceId | processName | status |
+----+----------+---------------------+---------------------+---------------+-------------------+-------------+--------+
