Add configuration class Redissessionconfig
= $)// default is 1800 seconds expired, here test modified to 60 second publicclass redissessionconfig {} Add a controller class Sessioncontroller to test
@RestController Public class Sessioncontroller { @RequestMapping ("/uid") String UID (HttpSession session) { = (UUID ) Session.getattribute ("UID"); if NULL ) { = uuid.randomuuid (); } Session.setattribute ("UID", UID); return Session.getid (); }}Visit Http://localhost:8083/boot/uid First
Then modify the configuration file Application.yml
Spring: Profiles: test
Re-run the Idea,test profile configuration port is 8085, so the browser input http://localhost:8085/boot/uid
We see that the two UID is the same.
Here I use spring boot Redis for session sharing, and you can load balance with Nginx and share session.
About Nginx can refer to my other article: Nginx Detailed-server cluster
Spring Boot InternationalizationInternationalization is a simple thing to do in spring boot.
(1) Under the Resources directory, we create a few new resource files, messages.properties equivalent to the default configuration, when the other configuration can not find the record, the final will be in this configuration file to find.
Messages.propertiesmessages_en_us. propertiesmessages_zh_cn. Properties
Add the following configuration values in each of the three configuration files in turn:
Msg= , I'm Chinese .
msg=I ' m Chinese
Msg= , I'm Chinese .
Once added, these files are automatically wrapped in a
It should be noted that this naming is fastidious,messages.properties parts are fixed, in different languages, we can distinguish between them by _. Why is a fixed name, because the source code is hard-coded so named.
(2) Create a new configuration file localeconfig
@Configuration @enableautoconfiguration@componentscan Public classLocaleconfigextendsWebmvcconfigureradapter {@Bean Publiclocaleresolver Localeresolver () {sessionlocaleresolver SLR=NewSessionlocaleresolver (); //Default LanguageSlr.setdefaultlocale (Locale.china); returnSLR; } @Bean Publiclocalechangeinterceptor Localechangeinterceptor () {Localechangeinterceptor LCI=NewLocalechangeinterceptor (); //Name of parameterLci.setparamname ("Lang"); returnLCI; } @Override Public voidaddinterceptors (Interceptorregistry registry) {Registry.addinterceptor (Localechangeinterceptor ()); }}
(3) In the controller, we add the method of testing
//i18n@RequestMapping ("/") PublicString i18n () {return"I18n"; } @RequestMapping ("/changesessionlanauage") Publicstring Changesessionlanauage (httpservletrequest request, httpservletresponse Response, String lang) {System.ou T.println (lang); Localeresolver Localeresolver=Requestcontextutils.getlocaleresolver (Request); if("zh". Equals (lang)) {Localeresolver.setlocale (Request, Response,NewLocale ("zh", "CN")); }Else if("en". Equals (lang)) {Localeresolver.setlocale (Request, Response,NewLocale ("en", "US")); } return"redirect:/"; }
(4) Add view to show, create new file under Templates i18n.html, through # can get the value of configuration item in internationalization configuration file directly.
