工作流中的请假流程
某人提出请假申请,先由项目经理审批,如果项目经理不同意,审批就直接结束
如项目经理同意,再看是否超过3天,如果三天以内,审批直接结束
否则,交给部门经理,部门经理审核后,无论是否同意,审批直接结束
状态类

package com.cmc; public abstract class State { public abstract void shenPi(Work w); } |
项目经理类,继承了状态类,并实现了状态由项目经理审批转移至部门经理审批:

package com.cmc; public class ProjectManager extends State { @Override public void shenPi(Work w) { if (w.isManagermentAccept()== false ){ System.out.println( "项目经理不同意,审批结束!" ); } else { if (w.getDay()<= 3 ){ System.out.println( "请假时间在三天以内,项目经理同意,审批结束" ); } else { System.out.println( "请假时间大于三天,移交给部门经理处理!" ); w.setCurrent( new PartmentMeneger()); w.shenPi(); } } } } |
部门经理类:

package com.cmc; public class PartmentMeneger extends State { @Override public void shenPi(Work w) { System.out.println( "已经过部门经理审批,审批结束!" ); } } |
工作类,拥有一个State的对象,在shenPi方法中将自己回传给State:
