使用输入流写一个对象

这个不知道算是代理模式还是装饰者模式，不过本人认为更像是一个代理模式，继承了outputstream类，但是不用实现它的方法，而是另添加一个方法，可以直接写入一个对象

package io.proxy;

import java.io.Serializable;

public class User implements Serializable {
	private String account;
	private String password;
	public String getAccount() {
		return account;
	}
	public void setAccount(String account) {
		this.account = account;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	
}

package io.proxy;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;

import com.alibaba.fastjson.JSONObject;

public class FreshbinOutputStream extends OutputStream {
	
	private FileOutputStream out;
	
	public FreshbinOutputStream(String filePath) throws FileNotFoundException {
		this.out = new FileOutputStream(filePath,true);
	}

	public void write(Object user) {
		try {
			String jsonstr = JSONObject.toJSONString(user);
			out.write(jsonstr.getBytes());
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}		
	}

	public void close(){
		if(out != null) {
			try {
				out.close();
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
	}
	
	@Override
	public void write(int arg0) throws IOException {
		// TODO Auto-generated method stub
		
	}
}

package io.proxy;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;

public class Test {
	
	public static void main(String[] args) {
		User us1 = new User();
		us1.setAccount("freshbin");
		us1.setPassword("123");

		FreshbinOutputStream fos = null;
		try {
			fos = new FreshbinOutputStream("h:/test/test.txt");
			fos.write(us1);
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} finally {
			fos.close();
		}

	}
}
