MutablePropertyValues的簡單用法

代碼例子：

package com.cy.model;

import lombok.Getter;
import lombok.Setter;
import lombok.ToString;

@Getter
@Setter
@ToString
public class Apple {
    private String id;
    private String name;
}

MutablePropertyValues的使用：

package com.cy.test.spring;

import com.cy.model.Apple;
import org.springframework.beans.BeanWrapper;
import org.springframework.beans.MutablePropertyValues;
import org.springframework.beans.PropertyAccessorFactory;

public class TestMutablePropertyValues {

    public static void main(String[] args) {
        //Apple的屬性名稱
        String[] properties = new String[]{"id", "name"};
        MutablePropertyValues pvs = new MutablePropertyValues();

        for(int i=0; i<properties.length; i++){
            String property = properties[i];
            String value = "test" + i;
            pvs.add(property, value);
        }

        Apple p = new Apple();
        BeanWrapper wrapper = PropertyAccessorFactory.forBeanPropertyAccess(p);
        wrapper.setPropertyValues(pvs);
        System.out.println(p);
    }
}

打印結果：

Apple(id=test0, name=test1)

注：

1.MutablePropertyValues中設置的屬性值類型，要和Apple中屬性對應的值類型要匹配，不然會報錯。java.lang.NumberFormatException等等。
