java - Multiple servlets with different context in one Spring application -
i have spring application, has have 2 servlets (dispatchermain , dispatchercatalog) working different databases via hibernate (finance , finances_global).
first, in web.xml define:
- parent context config location (
application-config.xml) - servlets , own:
- context config locations (
dispatchermain-servlet.xml,dispatchercatalog-servlet.xml) - hibernate datasources config files (
databaseconfigmain.xml,databaseconfigcatalog.xml).
- context config locations (
second, in each of servlets' config file, create bean mainconfig reads resource bundle - separate each servlet (mainservlet.properties , catalogservlet.properties).
but turns out that configuration files never read, deployment failes. in log file, have lots of java.lang.runtimeexception: can't read property "server.redis" , caused by: java.lang.nullpointerexception @ klab.backend.utils.mainconfig.get(mainconfig.java:351).
what doing wrong?
here configs.
