feilong-core 1.10.1 发布了,是一个让 Java 开发更简便的工具包, 可以让你从大量重复的底层代码中脱身,提高工作效率; 让你的代码更简炼,易写、易读、易于维护; 本次升级共有4处变更,具体参见 1.10.1 milestone 1.10.1 文档地址: http://feilong-core.mydoc.io/ 1.特性 添加 MapUtil.get(Map<K, V>, int) fix #595 添加 List<O> collect(Iterable<I> inputBeanIterable,Class<O> outputListBeanType,String...includePropertyNames) method fix #559 假设你有两个类, User,Customer 此时你需要将 List<User> 转换成 List<Customer> List<User> list = toList( new User(23L, "张飞"), new User(24L, "关羽"), new User(25L, "刘备")); 以前你需要如此这般写: List<Customer> customerList = new ArrayList<>(); for (User user : list){ Customer customer = new Customer(); customer.setId(user.getId()); customer.setName(user.getName()); customerList.add(customer); } 如果属性很多,书写代码很繁琐 现在你可以这么写: List<Customer> customerList = CollectionsUtil.collect(list, Customer.class); 一行代码搞定集合转换问题 如果你只想转换id属性,你可以: List<Customer> customerList = CollectionsUtil.collect(list, Customer.class,"id"); 添加 IgnoreCaseEquator fix #597 添加 BeanPredicateUtil.equalIgnoreCasePredicate(String,String) fix #598 在list中查找 name是 zhangfei(忽视大小写) 的user List<User> list = toList( new User("zhangfei", 22), new User("zhangFei", 22), new User("Zhangfei", 22), new User((String) null, 22), new User("guanyu", 25), new User("liubei", 30) ); List<User> select = select(list, BeanPredicateUtil.<User> equalIgnoreCasePredicate("name", "zhangfei")); 2.修改 none 3.移除 none 4.Bug 修复 change CollectionsUtil.collect method, 如果入参是null,那么返回null fix #601 feilong-core 1.10.1,让 Java 开发更简便的工具包下载地址
