使用反射将Object转换为HashMap

代码

public class MapUtils {


    /**
     * 使用反射获取对象的成员名作为key,值作为value
     *
     * @param o
     * @return
     */
    public static Map<String, String> objectField2Map(Object o) {
        Map<String, String> result = new HashMap<>();
        if (o == null) return result;
        Class oClass = o.getClass();
        Field[] fields = oClass.getDeclaredFields() ;
        String key;
        String value;
        if (fields != null && fields.length != 0) {
            for (Field field : fields) {
                try {
                    key = field.getName();
                    if ("serialVersionUID".equalsIgnoreCase(key)) continue;
                    field.setAccessible(true);
                    Object o1 = field.get(o) ;
                    value = o1.toString();
                    result.put(key, value);
                } catch (IllegalAccessException e) {
                    continue;
                }
            }
        }
        return result;
    }
}
