利用beanutils反射bean时类型转换问题

bean类

import java.util.Date;
public class Chenyujie {
private Date birthday;
public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
}

类型转换中api的使用

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.converters.DateConverter;
//import org.apache.commons.beanutils.locale.converters.DateLocaleConverter;
import cn.neu.domain.Chenyujie;
public class Utils {
public static void main(String[] args) throws IllegalAccessException, InvocationTargetException {

Chenyujie cyj = new Chenyujie();
//方式1
/*ConvertUtils.register(new DateLocaleConverter(), Date.class);
BeanUtils .setProperty(cyj, "birthday", "1990-08-13");*/
//方式二
DateConverter dateConverter = new DateConverter(null);
dateConverter.setPatterns(new String[]{"yyyy/MM/dd","yyyy-mm-dd"});
ConvertUtils.register(dateConverter, Date.class);
BeanUtils .setProperty(cyj, "birthday", "1999/08/13");
System.out.println(cyj.getBirthday());
}
}
