java设计模式（简例）----适配器模式

//创建DBConnection借口

package com.adepter.test;

public interface DBConnection {

	public void insert();
}

//创建DBConnection的实现类DBConnectionImpl

package com.adepter.test;

public class DBConnectionImpl implements DBConnection {

	@Override
	public void insert() {
		// TODO Auto-generated method stub
		System.out.println("这是DBConnection类");
	}

}

//创建Regist接口

package com.adepter.test;

public interface Regist {

	public void writeFile();
}

//创建Regist接口的实现类

package com.adepter.test;


public class RegistImpl implements Regist {

    @Override
    public void writeFile() {
        // TODO Auto-generated method stub
        System.out.println("这是Regist类");
    }

}

//创建Adpater适配器类，实现接口的回调

package com.adepter.test;

public class Adapter implements Regist {

	public DBConnection dbcon;
	
	public Adapter(DBConnection dbcon){
		this.dbcon=dbcon;
	}
	@Override
	public void writeFile() {
		// TODO Auto-generated method stub
		dbcon.insert();
	}

}

//创建Test测试类

package com.adepter.test;

public class Test {

    
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        DBConnection dbcon=new DBConnectionImpl();
        Regist reg=new Adapter(dbcon);
        reg.writeFile();
    }

}
