Use math.Random()

Any one have spring security ashok it

krishnamoorthi1804 2022-07-14 19:27:22

No i have to use uuid for it

pragya0508 2022-07-14 19:33:40

No i have to use uuid for it

UUID is not for that purpose, you have to build your logic using math.Random()

You have done it nicely. I liked the way you have programmed to an interface. This will give you a lot of flexibility and provides loose coupling and will also help you in writing unit tests. Few suggestions:

1. The package name in java should start with a lowercase

2. Inside TodoRepoImp::getAllTodo() you can try using

var rowMapper = BeanPropertyRowMapper.newInstance(Todo.class);
List<Todo> rows = template.query(q, rowMapper);
This will help you in getting rid of a lot of boilerplate code you are doing. You can also try using the same suggestion in getTodoById() method

3. Write unit tests

I hope this helps and all the best for your future endeavors

You can also use lombok api to reduce the boiler plate coding
