反射之設置對象字段值以及根據字段獲取對象字段值

1、通過反射獲取對象的字段值

public static long getObjectValueByEnumField(String fieldName, Object object, Class<?> clazz) {
        try {
            //獲取字段
            Field field = clazz.getDeclaredField(HumpTranUtil.lineToHump(fieldName));
            PropertyDescriptor pd = new PropertyDescriptor(field.getName(), clazz);
            //獲取get方法
            Method getMethod = pd.getReadMethod();
            Object valueObj = ReflectionUtils.invokeMethod(getMethod, object);
            return valueObj == null ? 0 : Long.valueOf(valueObj.toString());
        } catch (Exception e) {
            log.info("通過反射根據字段名稱獲取對應字段的值出錯，fielaName={}", fieldName, e);
            return 0;
        }
    }

 

2、通過反射設置對象字段的值

 public static void setObjValueByEnumField(Object object, Class<?> clazz, String fieldName, long value) {
        try {
            //獲取字段
            Field field = clazz.getDeclaredField(HumpTranUtil.lineToHump(fieldName));
            field.setAccessible(true);
            field.set(object, value);
            field.setAccessible(false);
        } catch (Exception e) {
            log.info("通過反射根據字段名稱設置對應字段的值出錯，fieldName={}|value={}", fieldName, value, e);
        }
    }
