静态代理--java

接口 ：

package com.ccl.reflect;

public interface STest {

	public void each();

}

实现:

package com.ccl.reflect;

public class STestImpl implements STest {

	@Override
	public void each() {
		System.out.println("stest.");
	}

}

静态代理类:

package com.ccl.reflect;

public class StaticProxy {

	private STest impl;

	public StaticProxy(STest s) {
		this.impl = s;
	}

	public void each() {

		System.out.println("transation begin.");
		impl.each();
		System.out.println("transation end.");

	}

	public static void main(String args[]) {

		STest s = new STestImpl();

		StaticProxy proxy = new StaticProxy(s);

		proxy.each();

	}

}

Console:

transation begin.
stest.
transation end.
