java - How to configure a servlet init-param in a Spring boot application -

i have spring boot application (version 1.2.1.release) uses spring mvc, , need set development init parameter on jspservlet. in web.xml have looked following:

<servlet>         <servlet-name>jsp</servlet-name>         <servlet-class>org.apache.jasper.servlet.jspservlet</servlet-class>         ...         <init-param>             <param-name>development</param-name>             <param-value>false</param-value>         </init-param>          ... </servlet> 

i have thought this: how configure spring-boot servlet in web.xml?, don't think can replace new meteorservlet() new jspservlet() , go on way, sure jspservlet.init(servletconfig config) needs called valid servletconfig. and, of course if try without proper in initialization, application gives me null pointer exception (which occurs because private transient jspruntimecontext rctxt; null):

java.lang.nullpointerexception: null     @ org.apache.jasper.servlet.jspservlet.periodicevent(jspservlet.java:361)     @ org.apache.catalina.core.standardwrapper.backgroundprocess(standardwrapper.java:679)     @ org.apache.catalina.core.containerbase$containerbackgroundprocessor.processchildren(containerbase.java:1377)     @ org.apache.catalina.core.containerbase$containerbackgroundprocessor.processchildren(containerbase.java:1381)     @ org.apache.catalina.core.containerbase$containerbackgroundprocessor.run(containerbase.java:1349)     @ java.lang.thread.run(thread.java:745) 

also, have hacky way implementing tomcatembeddedservletcontainerfactory , providing servlet override init method , getinitparameter method of servletconfig, hateful, , hoping there better way. guidance appreciated.

lastly, code reads init-param in org.apache.jasper.embeddedservletoptions class , appears servletconfig init param can't specify context param (i don't think) awesome server.context-parameters.name=value.

string development = config.getinitparameter("development"); if (development != null) {     if (development.equalsignorecase("true")) {         this.development = true;     } else if (development.equalsignorecase("false")) {         this.development = false;     } else {         if (log.iswarnenabled()) {             log.warn(localizer.getmessage("jsp.warning.development"));         }     } 

}

and if try hit application anyway, following error:
