Answer 1

@RequestMapping(value="/list", method=RequestMethod.GET)//, headers=ACCEPT_JSON)
@ResponseBody
public List<User> userList() {
    LOG.info("get list of Users");

    List<User> users = new ArrayList<User>();
    users.add(new User("user1", "pass1", "name1", Boolean.TRUE));
    users.add(new User("user2", "pass2", "name2", Boolean.TRUE));
    users.add(new User("user3", "pass3", "name3", Boolean.TRUE));

    return users;
}
