Spring中的BeanUtils工具类用法

BeanUtils.copyProperties(destination, source);

String value = BeanUtils.getProperty(bean, "propertyName");
BeanUtils.setProperty(bean, "propertyName", "value");

// 自定义转换器
class CustomConverter implements Converter {
    public Object convert(Class type, Object value) {
        // 自定义转换逻辑
        return convertedValue;
    }
}

// 使用自定义转换器进行属性复制
ConvertUtils.register(new CustomConverter(), String.class);
BeanUtils.copyProperties(destination, source);

Map<String, String> properties = new HashMap<>();
properties.put("propertyName1", "value1");
properties.put("propertyName2", "value2");
BeanUtils.populate(bean, properties);

public class BaseConverter {
    /**
     * 对象属性赋值
     * @param source 源对象
     * @param clazz 目标类
     * @param properties
     * @param <K>
     * @return
     */
    public static <K> K convert(Object source, Class<K> clazz, String... properties) {
        if (source == null) {
            return null;
        }
        K target = (K) BeanUtils.instantiate(clazz);
        BeanUtils.copyProperties(source, target, properties);
        return target;
    }

    /**
     * List集合之间的对象属性赋值
     * @param sourceList 输入集合
     * @param clazz 输出集合类型

    public static <K> List<K> convertList(List<?> sourceList, Class<K> clazz, String... properties) {
        List<K> list = new ArrayList<K>();
        if (null == sourceList || sourceList.size() < 1) {
            return list;
        }
        for (Object source : sourceList) {
            if (null == source) {
