设计模式学习之状态模式：请假流程

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);
}

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();
			}
		}
	}

}

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！");
	}

}

package com.cmc;

public class Work {
	private State current;
	private int day;
	private boolean isManagermentAccept;
	public Work() {
		current = new ProjectManager();
	}
	public State getCurrent() {
		return current;
	}
	public void setCurrent(State current) {
		this.current = current;
	}
	public int getDay() {
		return day;
	}
	public void setDay(int day) {
		this.day = day;
	}
	public boolean isManagermentAccept() {
		return isManagermentAccept;
	}
	public void setManagermentAccept(boolean isManagermentAccept) {
		this.isManagermentAccept = isManagermentAccept;
	}
	public void shenPi(){
		current.shenPi(this);
	}
}

客户端测试一下：

package com.cmc;

public class Client {
	public static void main(String [] args){
		Work w = new Work();
		w.setDay(4);
		w.setManagermentAccept(true);
		w.shenPi();
	}
}
