使用Fork中的Script实现多路路由选择 在阅读本文之前，建议先阅读一下《JBPM源码解读之：Fork》以了解Fork中Script的配置方法及处理方式： 按照Fork对Script的规范Script必须包含一个具有write权限的变量，而且该变量必须实现java.util.Collection接口。 <?xml version="1.0" encoding="UTF-8"?> 附上单元测试代码： import junit.framework.TestCase; import org.jbpm.graph.def.ProcessDefinition; import org.jbpm.graph.exe.ProcessInstance; import org.junit.After; import org.junit.Before; import org.junit.Test; public class TestFork extends TestCase { private ProcessDefinition processDefinition; @Before public void setUp() throws Exception { String xmlPath = "jbpmTest/fork/jpdl/fork.xml"; processDefinition = ProcessDefinition.parseXmlResource(xmlPath); } @After public void tearDown() throws Exception { } @Test public void test() { ProcessInstance processInstance = new ProcessInstance(processDefinition); // processInstance.getContextInstance().setVariable("scenario", new Integer(1)); // processInstance.getContextInstance().setVariable("scenario", new Integer(2)); processInstance.getContextInstance().setVariable("scenario", new Integer(3)); processInstance.signal(); } }
