靜態切入點只在代理建立時執行一次，而不是在執行期間每次呼叫方法時都執行，所以效能比動態切入點要好，是首選的切入點方式。

在Spring中定義了兩個靜態切入點的實現類。

StaticMethodMatcherPointcut：一個抽象的靜態Pointcut，它不能被例項化。開發者可以根據自己擴充套件該類來實現自定義的切入點。

NameMatchMethodPointcut：只能對方法名進行判別的靜態Pointcut實現類。

靜態Pointcut例項：

package test.pointcut;

public class People {

	public void speak() {
		System.out.println("People Speaking");
	}
	
	public void run() {
		System.out.println("People Run");
	}
	
	public void talk() {
		System.out.println("People Talk");
	}
}
 

package test.pointcut;

import java.lang.reflect.Method;

import org.springframework.aop.ClassFilter;
import org.springframework.aop.support.StaticMethodMatcherPointcutAdvisor;

public class PeopleAdvisor extends StaticMethodMatcherPointcutAdvisor {

	@Override
	public boolean matches(Method method, Class<?> targetClass) {
		// TODO Auto-generated method stub
		return "speak".equals(method.getName());
	}

	public ClassFilter getClassFilter() {
		
		return new ClassFilter() {
			@Override
			public boolean matches(Class<?> clazz) {
				return People.class.isAssignableFrom(clazz);
			}
		};
	}
}
 

package test.pointcut;

import java.lang.reflect.Method;

import org.springframework.aop.MethodBeforeAdvice;

public class PeopleBeforeAdvice implements MethodBeforeAdvice {

	@Override
	public void before(Method method, Object[] args, Object target) throws Throwable {
		System.out.println(target.getClass().getSimpleName() + " is " + method.getName() + " !" );
	}

}

執行結果：

正則表示式：

前面的方法通過方法名定義切入點，如果有多個方法需要定義切入點，需要在實現類中多次判斷，如果多個目標的名字有一定的規則，使用正則表示式過濾，將減少許多麻煩。

在Spring中，RegexpMethodPointcutAdvisor是正則表示式方法匹配的切面實現類。該類功能比較全，一般情況下，不需要擴充套件該類，因此也省去了編寫通知的麻煩。

與之前的除了配置有一定差異以外，程式碼都是一樣的。

在定義切入點是經常使用的正則表示式：
