MutablePropertyValues的簡單用法

代碼例子：

 1 package com.cy.model;  2 
 3 import lombok.Getter;  4 import lombok.Setter;  5 import lombok.ToString;  6 
 7 @Getter  8 @Setter  9 @ToString 10 public class Apple { 11     private String id; 12     private String name; 13 }

View Code

MutablePropertyValues的使用：

 1 package com.cy.test.spring;  2 
 3 import com.cy.model.Apple;  4 import org.springframework.beans.BeanWrapper;  5 import org.springframework.beans.MutablePropertyValues;  6 import org.springframework.beans.PropertyAccessorFactory;  7 
 8 public class TestMutablePropertyValues {  9 
10     public static void main(String[] args) { 11         //Apple的屬性名稱
12         String[] properties = new String[]{"id", "name"}; 13         MutablePropertyValues pvs = new MutablePropertyValues(); 14 
15         for(int i=0; i<properties.length; i++){ 16             String property = properties[i]; 17             String value = "test" + i; 18  pvs.add(property, value); 19  } 20 
21         Apple p = new Apple(); 22         BeanWrapper wrapper = PropertyAccessorFactory.forBeanPropertyAccess(p); 23  wrapper.setPropertyValues(pvs); 24  System.out.println(p); 25  } 26 }

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，否則會報錯。java.lang.NumberFormatException等等。
