代码例子：
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 }
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的属性名称 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 }
打印结果：
Apple(id=test0, name=test1)
注：
1.MutablePropertyValues中设置的属性值类型，要和Apple中属性对应的值类型要匹配，不然会报错。java.lang.NumberFormatException等等。
