How to use @produces in JSON object spring boot -


is possible use @produces json objects in spring boot? or there way implement this:

jsonobject j_session = new jsonobject(); j_session.put("session_id_j", session_jid); j_session.put("j_app", "j"); j_session.put("rest_id_j", rest_id);

here simple example:

restcontroller class:   import java.util.arraylist; import java.util.list;  import org.springframework.web.bind.annotation.requestmapping; import org.springframework.web.bind.annotation.requestmethod; import org.springframework.web.bind.annotation.restcontroller;  import com.websystique.springboot.model.user;  @restcontroller @requestmapping("/api") public class restapicontroller {      @requestmapping(value = "/user/", method = requestmethod.get, produces = { "application/json" })     public list<user> listallusers() {         list<user> users = new arraylist<user>();         users.add(new user(1, "sam", 30, 70000));         users.add(new user(2, "tom", 40, 50000));         users.add(new user(3, "jerome", 45, 30000));         users.add(new user(4, "silvia", 50, 40000));         return users;     } }

the attribute produces = { "application/json" } automatically converts list collection json response.

below pojo class.

user pojo class   public class user {      private long id;      private string name;      private int age;      private double salary;      public user(){     }      public user(long id, string name, int age, double salary){         this.id = id;         this.name = name;         this.age = age;         this.salary = salary;     } }

sample json response:

[    {       "id":1,       "name":"sam",       "age":30,       "salary":70000    },    {       "id":2,       "name":"tom",       "age":40,       "salary":50000    },    {       "id":3,       "name":"jerome",       "age":45,       "salary":30000    },    {       "id":4,       "name":"silvia",       "age":50,       "salary":40000    } ]

follow link complete detailed example crud operations.

the above code link itself, modified controller part make simple.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
