    > 住在不同地方的双胞胎
4. [代理模式](./ProxyPatterns)
    > 专人专事
5. [策略模式](./StrategyPatterns)
    > 按照情景选择正确选项

# 列举SpringAOP、IOC、DI应用的代码片段

```java
@Aspect
public class Aop {

	@Pointcut("execution(* com.yang..*.*(..))")
	public void pointcut(){}

	@Before("pointcut()")
	public void before(){
		System.out.println("before");
	}

	@After("pointcut()")
	public void after(){
		System.out.println("after");
	}

	@Around("pointcut")
	public void around(){
		System.out.println("around");
	}

	@AfterThrowing(pointcut="pointcut()",throwing="error")
	public void afterThrowing(){
		System.out.println("afterThrowing");
	}
}
```

# IOC
```java
AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext("com.yang");
context.getBean(uncapitalize(ConfigForScanning.class.getSimpleName()));
```

# DI
```java
@Autowired
private Object service;
```
