java - Architecture Microservices Jhipster -

-

i want start architecture microservices of jhipster have doubts. have 4 pieces.

  • "hr" <- front , backend application
  • "selection" <- front , backend application
  • validation <- 1 database front
  • customers <- shared between "hr" , "select" in front in microservice , "hr" , "select".

both applications must validated against same database (jwt). both applications must share microservicio "customer" have backend, front in each of 2 applications.

  • 1 - "hr" gateway?
  • 2 - "selection" gateway?
  • 3 - how implement security both against same database (jwt) validated
  • 4 - "customer" microservicio?

sorry english.

your needs fit using jhipster in conjunction jhipster uaa.

general design

your first part model bounded contextes, such "hr", "selection" or "customer". microservice backend. every single item in model, "customer", or customers "address", or "hr" entity, called resources. these resources have divided wise across services.

using gateway

the jhipster gateway 2 things you. first, takes of microservices , expose them via single api gateway. secondary feature offers user interface (here: in bootstrap + angular). not force use interface. can use "jhipster:client" generator, generate 2 clients "hr" , "selection" js+html only, , serve them using plaig old nginx, , refer 1 jhipster gateway.

security

this uaa option comes play. using default jwt implementation force login user (which stored in gateway), if "customer" microservice calling "hr" microservice.

the uaa offers option of using oauth2 enable kinds of secure communication. in case can make "customer" service ask "hr" more privileged data, user allowed see, using feignclients or general "client credentials grant".

if users "customers", jhipster uaa becomes "customer" microservice.

if have time wait this feature beeing merged, implementing become easy declare communication interfaces similar jpa repositories, handle securing you.

wrap up

look how design architecture. use 1 gateway services (maybe without ui), generate ui later jhipster:client , serve them on nginx, , other things of logic have realized rest apis inside small microservices, , take of how use uaa.

to learn how use uaa right way, suggest take on my spring security article , my example application, using unmerged pr mentioned above. had no time write official docs this, yet. wrote general article, how use jhipster microservices, can read addtionally official documentation.

beyond this, free ask me further information!

good luck

i have order , ordersearch models. in order list (actionindex) gridview there filtering , sorting. on of columns in order order_total (sum of products in order). i need implement sum of order_total in gridview. if manually counting activedataprovider->getmodels() array_map spend 3 seconds 3000 orders (localhost). don't want miss time. i see 2 ways make faster: create cache every filter , update lifetime (horrible) the interesting can right in ordersearch->search() method $query method. don't understand how can pass in controller. example of code 2nd way: class ordersearch extends order { public $totalsum; public function search($params) { $query = order::find(); $dataprovider = new activedataprovider([ 'query' => $query, ]); $this->load($params); $this->totalsum = $query->sum('order_total'); // works fast return $dataprovider; } } after i

Sass watch command compiles .scss files before full sftp upload -

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course,
