BaseDao.getField()方法未正确过滤主键
public static void main(String[] args) { BaseDao<User, Long> userDao = new UserDao(null); List<Field> field = userDao.getField(new User(), false); System.out.println(field); }
返回结果中包含了被注解@pk标为主键的id。原因如下:
private List<Field> getField(T t, Boolean ignoreNull) { // 获取所有字段,包含父类中的字段 Field[] fields = ReflectUtil.getFields(t.getClass()); // 过滤数据库中不存在的字段,以及自增列 List<Field> filterField; Stream<Field> fieldStream = CollUtil.toList(fields).stream().filter(field -> ObjectUtil.isNull(field.getAnnotation(Ignore.class)) || ObjectUtil.isNull(field.getAnnotation(Pk.class))); // 是否过滤字段值为null的字段 if (ignoreNull) { filterField = fieldStream.filter(field -> ObjectUtil.isNotNull(ReflectUtil.getFieldValue(t, field))).collect(Collectors.toList()); } else { filterField = fieldStream.collect(Collectors.toList()); } return filterField; }
此函数过滤fieldStream时,filter中的两个过滤条件应当是与关系,并非或关系
