How do I catch BeanCreationException in Apache Camel route initialization to allow my Spring application to start anyway? -


i using apache camel , defined route receiving inputs 2 queues located on 2 distinct servers. want ideally consume both server want able run application when 1 of 2 destinations down.

here's route:

    try {         from("mccdsjmsrequest1:queue:{{mccds.queues.in}}").to("direct:apollomccdsroute");     } catch (exception e){         // debug line         system.out.println("ms1 not reachable");         e.printstacktrace();     }     try {         from("mccdsjmsrequest2:queue:{{mccds.queues.in}}").to("direct:apollomccdsroute");     } catch (exception e){         // debug line         system.out.println("ms2 not reachable");         e.printstacktrace();     }      from("direct:apollomccdsroute").routeid("apollomccdsroute")    // main route starts here...

i declare beans here:

@bean public jndiobjectfactorybean mccdsjmsconnectionfactory1() {     jndiobjectfactorybean cf = new jndiobjectfactorybean();     cf.setjndienvironment(prodmccdsjndiproperties.getjndi1());     cf.setjndiname(jndiname1);     return cf; }  @bean public jndiobjectfactorybean mccdsjmsconnectionfactory2(){     jndiobjectfactorybean cf = new jndiobjectfactorybean();     cf.setjndienvironment(prodmccdsjndiproperties.getjndi2());     cf.setjndiname(jndiname2);       return cf; }  @inject private camelcontext camelcontext;  @bean public jmscomponent mccdsjmsrequest1() {     jmscomponent ac = new jmscomponent(camelcontext);     ac.setconnectionfactory((connectionfactory) mccdsjmsconnectionfactory1().getobject());     ac.setconcurrentconsumers(5);     return ac; }  @bean public jmscomponent mccdsjmsrequest2(){     jmscomponent ac = new jmscomponent(camelcontext);     ac.setconnectionfactory((connectionfactory) mccdsjmsconnectionfactory2().getobject());     ac.setconcurrentconsumers(5);     return ac; }

if 1 of connection factory not reachable application doesn't start. catch ignore exception:

o.s.b.f.s.defaultlistablebeanfactory     : bean creation exception on non-lazy factorybean type check: org.springframework.beans.factory.beancreationexception: error creating bean name 'mccdsjmsconnectionfactory2' defined in class path resource [ca/bell/it/spa/uim/apollo/maximo/config/mccds/prodmccdsjmsconfiguration.class]: invocation of init method failed; nested exception javax.naming.communicationexception [root exception java.net.connectexception: t3://sometestserverip: destination unreachable; nested exception is:  java.net.connectexception: connection refused (connection refused); no available router destination]

try set lookuponstartup false. (add cf.setlookuponstartup(false) mccdsjmsconnectionfactory1 , mccdsjmsconnectionfactory2 bean definitions.)

vue.js - Create hooks for automated testing -

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
