模拟自动执行任务工作流的流程图:

 

 

 

 

工作流配置:

serviceTaskExpression.bpmn20.xml

Xml代码   收藏代码                                                                                   Welcome to Beijing                                                Hello Mr. Bai                                                                                                                                                                                                                              

 

工作流的实现:

Java代码   收藏代码 package com.easyway.activiti.servicetask;    import org.activiti.engine.delegate.DelegateExecution;    /**  * 从配置文件注入多个属性类型必须为Expression  * @author longgangbai  *   * 2011-12-20  下午10:08:01  */  public class ReverseStringsFieldInjected implements JavaDelegate {                private Expression text1;         private Expression text2;                public void execute(DelegateExecution execution) {           String value1 = (String) text1.getValue(execution);           execution.setVariable("var1", new StringBuffer(value1).reverse().toString());                  String value2 = (String) text2.getValue(execution);           execution.setVariable("var2", new StringBuffer(value2).reverse().toString());         }       }  

 

 

Java代码   收藏代码 package com.easyway.activiti.servicetask;    import org.activiti.engine.delegate.DelegateExecution;    /**  *  从配置文件注入一个字符串用于变为写  * @author longgangbai  *   * 2011-12-20  下午09:56:59  */  public class ToUppercase implements JavaDelegate {         private Expression text;         public void execute(DelegateExecution execution) throws Exception {             String value1 = (String) text.getValue(execution);              execution.setVariable("input", value1);         }                }
