list集合中String类型字段转换为BigDecimal类型求和

List<User> userList = new ArrayList<>();
User user1 = new User();
user1.setMoney("10.1");//double类型
userList.add(user1);
User user2 = new User ();
user2.setMoney("20.1");//double类型
userList.add(user2);
BigDecimal sumMoney = userList.stream().map(User::getMoney).map(BigDecimal :: new).reduce(BigDecimal.ZERO,BigDecimal::add);
