请求类
java
public class ApproverRequest {
private int type;//请求批准的类型
private float price;//请求的金额
private int id;//请求的编号
}
审批人抽象类
java
public abstract class ApproverPerson {
protected ApproverPerson next;
protected String name;
//审批过程
public abstract void processRequest(ApproverRequest request);
}
教导主任类
java
public class DepartmentApprover extends ApproverPerson {
@Override
public void processRequest(ApproverRequest request) {
System.out.println("教导主任正在处理批准...");
if (request.getPrice() <= 5000) {
System.out.println("请求编号 id= " + request.getId() + " 被教导主任 " + this.name + " 处理");
} else {
System.out.println("金额过大,教导主任处理不了,交给院长处理...");
next.processRequest(request);
}
}
}
院长类
java
public class CollegeApprover extends ApproverPerson {
@Override
public void processRequest(ApproverRequest request) {
System.out.println("院长正在处理批准...");
if (request.getPrice() > 5000 && request.getPrice() <= 10000) {
System.out.println("请求编号 id= " + request.getId() + " 被院长 " + this.name + " 处理");
} else {
System.out.println("金额过大,院长处理不了,交给副校长处理...");
next.processRequest(request);
}
}
}
副校长类
java
public class ViceSchoolMasterApprover extends ApproverPerson {
@Override
public void processRequest(ApproverRequest request) {
System.out.println("副校长正在处理批准...");
if (request.getPrice() > 10000 && request.getPrice() <= 15000) {
System.out.println("请求编号 id= " + request.getId() + " 被副校长 " + this.name + " 处理");
} else {
System.out.println("金额过大,副校长处理不了,交给校长处理...");
next.processRequest(request);
}
}
}
校长类
java
public class SchoolMasterApprover extends ApproverPerson {
@Override
public void processRequest(ApproverRequest request) {
System.out.println("校长正在处理批准...");
System.out.println("请求编号 id= " + request.getId() + " 被校长 " + this.name + " 处理");
}
}
演示类
java
public class Demo {
public static void main(String[] args) {
ApproverRequest request = new ApproverRequest(1, 20000, 1001);
ApproverPerson department = new DepartmentApprover("张主任");
ApproverPerson college = new CollegeApprover("李院长");
ApproverPerson viceSchoolMaster = new ViceSchoolMasterApprover("王副校长");
ApproverPerson schoolMaster = new SchoolMasterApprover("佟校长");
//设置当前审批人的指针,指向下一个审批人
department.setNext(college);
college.setNext(viceSchoolMaster);
viceSchoolMaster.setNext(schoolMaster);
department.processRequest(request);
}
}
