BeanShell脚本

BeanShell是一种小巧、嵌入式的Java脚本语言。

http://www.beanshell.org/

• AWS BPMN2引擎支持的版本 BeanShell2.0

常用变量

常规Java类型beanshell已经帮你引入，可以通过import引入特定的Java包

import 包路径

为了简化编程，我们封装了3个常用的入口变量，可在脚本中直接使用。

脚本示例

假如测试流程定义了v1变量，以下代码演示了ctx、sdk、dbsql变量的使用

var hello = "Hello World, BeanShell! - Script1";

//引擎上下文对象测试
var processInstId=ctx.getProcessInstance().getId();
var taskInstId=ctx.getTaskInstance().getId();
print("processInstId="+processInstId);
print("taskInstId="+taskInstId);
ctx.setVariable("v1", hello);
print("v1="+ctx.getVariable("v1"));

//SDK测试
print("AWSVersion="+sdk.getPlatformAPI().getAWSServer().getAWSVersion());

//DBSql测试
var param = new HashMap();
param.put("ID",taskInstId);
print("taskTitle= "+dbsql.getString("SELECT TASKTITLE FROM WFC_TASK WHERE ID=:ID","TASKTITLE",param));
//query records
var rows = dbsql.getList("SELECT * FROM WFC_TASK WHERE ID=:ID",param);
print("taskTitle= "+rows.get(0).get("TASKTITLE"));
print(rows);

运行时打印如下结果

processInstId=50c973dc-2638-41b3-b58e-2389d048cdf4
taskInstId=54c312f0-5958-4ba5-92a3-4b1be283ca9f

异常处理

可以像Java代码一样，抛出错误异常。下面我们用示例抛出BPMNError业务异常，并捕获进行处理。

import com.actionsoft.exception.BPMNError;

throw new BPMNError("ERR110","业务代码错误");

流程图如下
