Move接口
package com.spring.work01;
public interface Move {
void move();
}
实现
package com.spring.work01;
public class Tank implements Move{
@Override
public void move() {
System.out.println("tank is moving...");
}
}
package com.spring.work01;
public class TankProxy implements Move{
private Move t;
public TankProxy(Move t){
super();
this.t=t;
}
@Override
public void move() {
System.out.println("starting");
t.move();
System.out.println("stop ");
}
}
package com.spring.work01;
public class MoveApp {
public static void main( String[] args )
{
System.out.println( "" );
}
}
使用@AspectJ注解的例子
package com.spring.aspectj;
public class Tiger {
public void walk() {
System.out.println("Tiger is walking...");
}
}
- 定义切面和配置
前置通知和后置通知
Fighter类
package com.spring.aspectj;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
@Aspect
public class Fighter {
@Pointcut("execution(* com.spring.aspectj.Tiger.walk())")
public void foundTiger() {
}
@Before(value = "foundTiger()")
public void foundBefore() {
System.out.println("Fighter wait for tiger...");
}
@AfterReturning("foundTiger()")
public void foundAfter() {
System.out.println("Fighter fight with tiger...");
}
}
<!--启动AspectJ支持-->
<aop:aspectj-autoproxy/>
<!--配置bean-->
<bean id="tiger" class="com.spring.aspectj.Tiger"/>
<bean id="fighter" class="com.spring.aspectj.Fighter"/>
package com.spring.aspectj;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class FighterApp {
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
Tiger tiger = context.getBean(Tiger.class);
tiger.walk();
}
}
在IDEA中进行远程库推送的步骤
1.在settings中设置gi t和github
2.创建本地项目和远程项目
3.在VCS菜单中，找到git的remotes, 用git协议添加远程库
4.编写程序
5.选中项目，ctrl+alt+a添加文件， 如果冲突，用菜单操作
6. ctrl+K, 进行commi t提交
7. ctrl+shift+k,进行push操作
