Complete the following API:

• User sign up
  POST /users/sign-up with username, email and password.
• User sign in
  POST /users/sign-in with username and password.
• User sign out
  GET /users/sign-out.

If so, we can manipulate the whole HTTP response.

Review src/main/java/models/User.java.

There is an @JsonIgnore behind password field of domain class User, which causes a bug that the deserializer ignore the password field.

I run all the tests successfully in my own environment, whereas when pushing up and trying merging my branch into your master branch, the Travis logged and displayed errors as below:

which showing it ran 3 tests, but just 2 on mine. And the file containing the error information hinted by Travis is not my own.

So I don't think my code containing errors. Just merge my branch.

How to get a part of an Object ?
@zccz14

@ErinLq

Protocol Buffers(GFW proxy required) are a language-neutral, platform-neutral extensible mechanism for serializing structured data.

So the official website showed.
On which plenty of Google projects used as resource(data) representation.

This is a long term enhancement. Consider it only when we met the performance bottleneck of data transmission. And for the readability, JSON is the peerless choice.

So take it easy, as a interesting new tech to know.

We need a series of Error class to help with error handling.

reform out team and reschedule the project and... finish it.

Review src/main/java/com/funcxy/oj/models/Submission.java.

Here is my router for GET in problem controller:

  @RequestMapping(method = RequestMethod.GET)
    public List<Problem> getProblem(Problem problem){
        return problemService.find(problem);
    }

And codes for find() in problemService:

 public List<Problem> find(Problem problem) {
        List<Problem> problemList = new ArrayList<>();
        if (problem.getType() != null)
            problemList.addAll(findByType(problem.getType()));
        System.out.println(problemList);
        if (problem.getTitle() != null)
            problemList.retainAll(findByTitle(problem.getTitle()));
        System.out.println(problemList);
        if (problem.getCreator() != null)
            problemList.addAll(findByCreator(problem.getCreator()));
        return problemList;
    }

And according to the discussion before, users can use title or type or creator or some other things to identify a sort of problems. So here comes the dilemma: if a user uses both type and title to identify a specific problem(more precisely, many problems whose type and title are the same.), we need to get the intersection of problems from both findByType() and findByTitle()(Right?).
But the method retainAll() in interface List<> just compares the references rather than their inner contents, when we try getting the intersection from those two methods, we will get none.(Because we access MongoDB twice, so the two methods actually give back two different references.)

How to solve this? Maybe solve it in the front-end? @zccz14 @zccz14 @zccz14
