java - Spring Boot and Spring Data application with multiple DataSources created in runtime -

-

i developing spring boot application uses spring data jpa , need connect many different databases e.g. postresql, mysql, ms-sql, mongodb. need create datasources in runtime i.e. user choose these data gui in started application: -driver(one of list), -source, -port, -username, -password. , after writes native sql choosen database , results. read lot of things in stack , spring forums(e.g. abstractroutingdatasource) of these tutorials show how create datasources xml configuration or static definition in java bean. possible create many datsources in runtime? how manage transactions , how create many sessionfactories? possible use @transactional annotation? best method this? can explain me how 'step step'?

hope it's not late answer ;)

i developed module can integrated in spring project. uses meta-datasource hold tenant-datasource connection details. tenant-datasource abstractroutingdatasource used.

here find core implementation using abstractroutingdatasource. https://github.com/dactabird/multitenancy

here example show how integrate it. https://github.com/dactabird/multitenancy-sample in example i'm using h2 embedded db. of course can use whatever want.

feel free modify purposes or ask if questions left!

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
