【BeanUtils】操作JavaBean

BeanUtils提供对 Java反射和自省API的包装。其主要目的是利用反射机制对JavaBean的属性进行处理。

Person.class

package com.xiaozhi.beanutils;

import java.util.Date;

public class Person {
	private String name;
	private String password;
	private int age;
	private Date birthday;
	public Date getBirthday() {
		return birthday;
	}
	public void setBirthday(Date birthday) {
		this.birthday = birthday;
	}
	public String getName() {
		return name;
	}
	public String getPassword() {
		return password;
	}
	public int getAge() {
		return age;
	}
	public void setName(String name) {
		this.name = name;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public void setAge(int age) {
		this.age = age;
	}

}

Test.java

package com.xiaozhi.beanutils;

import java.lang.reflect.InvocationTargetException;
import java.util.Date;

import org.apache.commons.beanutils.BeanUtils;
import org.apache.commons.beanutils.ConvertUtils;
import org.apache.commons.beanutils.locale.converters.DateLocaleConverter;

public class Test {

	public static void main(String[] args) throws Exception, InvocationTargetException {
		//使用beanUtils操纵bean的属性
//		Person person=new Person();
//		BeanUtils.setProperty(person, "name", "xiaozhi");
//		System.out.println(person.getName());
//		System.out.println(BeanUtils.getProperty(person, "name"));
		
		
		 //beanUtilsz支持八种类型自动转换
//		String name="xiaozhi";
//		String age="22";
//		String password="123456";
//		
//		Person person=new Person();
//		BeanUtils.setProperty(person, "name", name);
//		BeanUtils.setProperty(person, "age", age);
//		BeanUtils.setProperty(person, "password", password);
//		
//		System.out.println(person.getName());
//		System.out.println(person.getAge());
//		System.out.println(person.getPassword());
		
		//对于时间类型，要注册转换器
		String birthday ="1992-09-28";
		ConvertUtils.register(new DateLocaleConverter(), Date.class);
		Person person=new Person();
		BeanUtils.setProperty(person, "birthday", birthday);
		System.out.println(person.getBirthday());
