具体参见 1.9.5 milestone
1.特性 🆕
-
ConvertUtil
添加Map<K, V> toMap(K key1,V value1,K key2,V value2)
方法 fix #550该方法非常适合快速构造一个2个key的Map场景
比如对于以下代码:
Map<String, Long> map = new HashMap<>(); map.put("itemId", itemId); map.put("memberId", memberId); memberFavoritesDao.findMemberFavoritesByMemberIdAndItemId(map);
上面
4行
代码,可以重构成2行
:Map<String, Long> map = ConvertUtil.toMap("itemId", itemId, "memberId", memberId); memberFavoritesDao.findMemberFavoritesByMemberIdAndItemId(map);
-
BeanPredicateUtil
添加Predicate<T> equalPredicate(Map<String, ?> propertyNameAndPropertyValueMap)
方法 fix #113使用示例: 在list中查找 名字是 关羽,并且 年龄是30 的user
此时你可以:
User guanyu30 = new User("关羽", 30); List<User> list = ConvertUtil.toList(// new User("张飞", 23), new User("关羽", 24), new User("刘备", 25), guanyu30); Map<String, Object> map = ConvertUtil.toMap("name", "关羽", "age", 30); User result=com.feilong.core.util.CollectionsUtil.find(list, BeanPredicateUtil.<User> equalPredicate(map)); assertEquals(guanyu30, result);
寥寥几行代码,就可以搞定
-
BeanPredicateUtil.equalPredicate(String, V)
添加更多的 javadoc fix #546 -
添加更多的单元测试
2.修改
ConvertUtil
Map<K, V> toMap(Map.Entry<K, V>...mapEntrys)
方法重命名成Map<K, V> toMapUseEntrys(Map.Entry<K, V>...mapEntrys)
fix #549
3.移除
NumberFormatUtil
删除String format(Number value,String numberPattern)
方法, 请直接调用NumberUtil
String toString(Number value,String toStringPattern)
fix #245
4.Bug 修复 🐛
-
ParamUtil.toQueryStringUseArrayValueMap(Map<String, String[]>)
如果 map has value is null,返回paramName=
fix #372示例:
Map<String, String[]> keyAndArrayMap = new LinkedHashMap<>(); keyAndArrayMap.put("province", null); keyAndArrayMap.put("city", new String[] { "南通市" }); assertEquals("province=&city=南通市", ParamUtil.toQueryStringUseArrayValueMap(keyAndArrayMap));
