java中如何进行对象属性复制呢?

实现思路:
     1.Apache提供的BeanUtil.copyProperties和PropertyUtil.copyProperties两种方式
	 2.Spring中BeanUtils.copyProperties("转换后的类", "要转换的类");
	 3.cglib提供的copy方式
	 4.Spring提供的copy方式

 
//1.Apache方式
import org.apache.commons.beanutils.BeanUtils;
import java.lang.reflect.InvocationTargetException;

public class TestDemo {
    public static void main(String[] args) {
        TestFrom testFrom = new TestFrom();
        testFrom.setName("java265.com");
        TestTo testTo = new TestTo();
        BeanUtils.copyProperties(testTo,testFrom);
     }
}

//2.spring提供的BeanUtil.copyProperties方式
import org.springframework.beans.BeanUtils;
public class TestDemo {
    public static void main(String[] args) {
        TestFrom testFrom = new TestFrom();
        testFrom.setName("java265.com");
        TestTo testTo = new TestTo();
        BeanUtils.copyProperties(testFrom,testTo);//没抛异常
    }
}

//3.cglib提供的copy方式
import net.sf.cglib.beans.BeanCopier;
public class TestDemo {
    public static void main(String[] args) {
        TestFrom testFrom = new TestFrom();
        testFrom.setName("java265.com");
        TestTo testTo = new TestTo();
        BeanCopier copier = BeanCopier.create(TestFrom.class,TestTo.class,false);
        copier.copy(testFrom,testTo,null);
    }
}

//4.spring提供的copy方式
import org.springframework.cglib.beans.BeanCopier;
public class TestDemo {
    public static void main(String[] args) {
        TestFrom testFrom = new TestFrom();
        testFrom.setName("java265.com");
        TestTo testTo = new TestTo();
		BeanCopier copier = BeanCopier.create(TestFrom.class,TestTo.class,false);
		copier.copy(testFrom,testTo,null);
    }
}
