commons-beanutils-1.8.3 动态设置属性

commons beanutils-动态设置属性
beanutils其实就是对反射的封装.下面做个动态设置属性的实验.

package test.common.beanutils;

import org.apache.commons.beanutils.PropertyUtils;

import test.common.db.Var;

public class BeanTest {
	public static void main(String[] args) throws Exception {
		DataValue dv = new DataValue();
		for (int i = 1; i <= 5; i++) {
			PropertyUtils.setProperty(dv, "data" + String.format("%02d", i), i);
		}
		PropertyUtils.setProperty(dv, "var", new Var());
		PropertyUtils.setProperty(dv, "var.id", "phl");
		PropertyUtils.setProperty(dv, "var.date_Time", "2010-08-04");

		// 打印看看
		for (int i = 1; i <= 5; i++) {
			System.out.println(PropertyUtils.getProperty(dv, "data" + String.format("%02d", i)));
		}
		System.out.println(PropertyUtils.getProperty(dv, "var.date_Time"));
	}
}

package test.common.beanutils;

import test.common.db.Var;

public class DataValue {
	public int data01;
	public int data02;
	public int data03;
	public int data04;
	public int data05;
	public Var var;
	public int getData01() {
		return data01;
	}
	public void setData01(int data01) {
		this.data01 = data01;
	}
	public int getData02() {
		return data02;
	}
	public void setData02(int data02) {
		this.data02 = data02;
	}
	public int getData03() {
		return data03;
	}
	public void setData03(int data03) {
		this.data03 = data03;
	}
	public int getData04() {
		return data04;
	}
	public void setData04(int data04) {
		this.data04 = data04;
	}
	public int getData05() {
		return data05;
	}
	public void setData05(int data05) {
		this.data05 = data05;
	}
	public Var getVar() {
		return var;
	}
	public void setVar(Var var) {
		this.var = var;
	}
}

package test.common.db;

import org.apache.commons.lang.builder.ToStringBuilder;
import org.apache.commons.lang.builder.ToStringStyle;

public class Var {
	private String id;
	private float value_t;
	private String Date_Time;

	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

	public float getValue_t() {
		return value_t;
	}

	public void setValue_t(float valueT) {
		value_t = valueT;
	}

	public String getDate_Time() {
		return Date_Time;
	}

	public void setDate_Time(String dateTime) {
		Date_Time = dateTime;
	}
}
