1.10.1

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
