这一章节我们讨论一下扩展增加检查订单功能,以便记录并检测输入的参数。
1.domain
蛋糕类:
package com.raylee.my_new_spring.my_new_spring.ch03.topic_1_8;public class Cake {private String name = "";public String getName() {return name;}public void setName(String name) {this.name = name;}}
烤炉类:
package com.raylee.my_new_spring.my_new_spring.ch03.topic_1_8;public class Oven {private String name = "";@Overridepublic String toString() {return name;}public String getName() {return name;}public void setName(String name) {this.name = name;}}
厨师类:
package com.raylee.my_new_spring.my_new_spring.ch03.topic_1_8;public class Chief {private static int index = 0;public static int getIndex() {return index;}public static void setIndex(int index) {Chief.index = index;}private Cake cake = null;private final int id = index++;private String name = "";private Oven oven = null;public Cake getCake() {return cake;}public int getId() {return id;}public String getName() {return name;}public Oven getOven() {return oven;}public void setCake(Cake cake) {this.cake = cake;}public void setName(String name) {this.name = name;}public void setOven(Oven oven) {this.oven = oven;}public void makeOneCake(Cake cake) {System.out.println(getName() + " make " + cake.getName());}}
日志类:
package com.raylee.my_new_spring.my_new_spring.ch03.topic_1_8;import org.aspectj.lang.JoinPoint;import org.aspectj.lang.ProceedingJoinPoint;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;import org.aspectj.lang.annotation.Pointcut;@Aspectpublic class Log {@Pointcut(value = "execution(* com.raylee.my_new_spring.my_new_spring.ch03.topic_1_8.Chief.*(..))")public void chiefPointCut() {}public void washOven() {System.out.println("washOven,logging.....");}@Before("chiefPointCut()")public void checkOrder(JoinPoint joinpoint) {for (Object item : joinpoint.getArgs()) {if (item instanceof Cake) {Cake cake = (Cake) item;System.out.println(cake.getName());}}}public void prepare() {System.out.println("prepare,logging.....");}public void after() {System.out.println("after someting to do,logging.....");}public void around(ProceedingJoinPoint joinPoint) throws Throwable {washOven();prepare();long startTime = System.currentTimeMillis();joinPoint.proceed();long endTime = System.currentTimeMillis();System.out.println("use time:" + (endTime - startTime));after();}}
配置类:(我们这里使用基于java的配置)
package com.raylee.my_new_spring.my_new_spring.ch03.topic_1_4;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;@Configurationpublic class SpringBeans {@Beanpublic Chief jack() {Chief chief = new Chief();chief.setName("jack");chief.setOven(oven());chief.setCake(cake());return chief;}@Beanpublic Oven oven() {Oven oven = new Oven();oven.setName("big oven");return oven;}@Beanpublic Cake cake() {Cake cake = new Cake();cake.setName("blueberryCheeseCake");return cake;}@Beanpublic Log log() {return new Log();}}
2.测试类:
package com.raylee.my_new_spring.my_new_spring.ch03.topic_1_8;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.ApplicationContext;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = {"/com/raylee/my_new_spring/my_new_spring/ch03/topic_1_8/ApplicationContext-test.xml" })public class ChiefTest {@Autowiredprivate ApplicationContext applicationContext;@Testpublic void testChief() {Chief jack = (Chief) applicationContext.getBean(Chief.class);Cake cake = applicationContext.getBean(Cake.class);cake.setName("blueberryCheeseCake");jack.makeOneCake(cake);}}
3.配置文件
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"xmlns:aop="http://www.springframework.org/schema/aop" xmlns:util="http://www.springframework.org/schema/util"xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsdhttp://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.1.xsdhttp://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.0.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd"><context:component-scanbase-package="com.raylee.my_new_spring.my_new_spring.ch03.topic_1_8" /><aop:aspectj-autoproxy /></beans>
测试输出:
blueberryCheeseCake
jack make blueberryCheeseCake
