软件体系结构——工厂模式
(1)UML设计图
简单工厂模式UML:
普通工厂模式UML：
抽象工厂模式UML：
(2)核心实现代码
简单工厂模式：
| public class Simple extends javax.swing.JFrame { private void viewButtonActionPerformed(java.awt.event.ActionEvent evt) { // TODO add your handling code here: String option = (String)chooseInsur.getSelectedItem(); AutoInsurance ai = null;
//再获取具体的保险理赔对象 switch (option) { case "驾驶员身体受伤": ai = new BodyInjur(); break; case "汽车损坏": ai = new CarInjur(); break; case "人员伤亡": ai = new PersonInjur(); break; case "多种事故": ai = new OtherAccident(); break; }
insurInfoText.setText(ai.getInsurInfo()); }
|
普通工厂模式：
| public class Normal extends javax.swing.JFrame { private void viewButtonActionPerformed(java.awt.event.ActionEvent evt) { // TODO add your handling code here: String option = (String)chooseInsur.getSelectedItem();
PolicyProducer pp = null;
//再获取具体的保险理赔对象 switch (option) { case "驾驶员身体受伤": pp = new BodyPolicy(); break; case "汽车损坏": pp = new CarPolicy(); break; case "人员伤亡": pp = new PersonPolicy(); break; case "多种事故": pp = new OtherPolicy(); break; } AutoInsurance ai = pp.getInsurObj(); insurInfoText.setText(ai.getInsurInfo()); } |
抽象工厂模式：
| public class Abstract extends javax.swing.JFrame {
private void viewButtonActionPerformed(java.awt.event.ActionEvent evt) { // TODO add your handling code here: String company = (String)chooseCompany.getSelectedItem(); String option = (String)chooseInsur.getSelectedItem();
AutoInsurance ai = null;
//先获取具体的保险公司对象 Company c = Company.getCompany(company);
//再获取具体的保险理赔对象 switch (option) { case "驾驶员身体受伤": ai = c.getBodyInjur(); break; case "汽车损坏": ai = c.getCarInjur(); break; case "人员伤亡": ai = c.getPersonInjur(); break; case "多种事故": ai = c.getOtherInjur(); break; }
insurInfoText.setText(company+"：\n"+ai.getInsurInfo()); }
