Looping流程如下图所示：

如上图所示，Looping流程有三个Script Task节点，Init, Loop, Done。

Init节点是Loop开始节点，它初始化两个变量count和i，分别赋值5和0，如下

System.out.println("Loop started"); kcontext.setVariable("count", 5); kcontext.setVariable("i", 0);

Loop节点每次输出变量i的值，并给变量i加1,当变量i小于count的值5时，执行循环，如下

System.out.println(" i = " + i); kcontext.setVariable("i", i+1);

Done节点输出Looping流程结束字符串，如下

System.out.println("Loop completed");

*  Looping流程运行代码：[https://github.com/kylinsoong/.../looping/LoopingStart.java][https_github.com_kylinsoong_..._looping_LoopingStart.java]
 *  Looping流程：[https://github.com/kylinsoong/.../quickstarts/looping.bpmn][https_github.com_kylinsoong_..._quickstarts_looping.bpmn]

运行 org.jbpm.quickstarts.looping.LoopingStart可运行Looping流程， LoopingStart代码如下

package org.jbpm.quickstarts.looping; import org.drools.runtime.StatefulKnowledgeSession; import org.jbpm.quickstarts.QuickStartBase; public class LoopingStart extends QuickStartBase{ public void test() { StatefulKnowledgeSession ksession = createKnowledgeSession("quickstarts/looping.bpmn"); ksession.startProcess("org.jbpm.quickstarts.looping"); } public static void main(String[] args) { new LoopingStart().test(); } }

运行 Looping流程输出结果如下：

Loop started i = 0 i = 1 i = 2 i = 3 i = 4 Loop completed
