Dear Fellow Developers, Just recently, I tried to upgrade my camel-spring boot project form camel 2.19.3 to camel 2.20.0 and I face the problem that, I cannot boot up my application any more, and I get the following stack trace
java.lang.NullPointerException at com.haufe.ssmp.sfdc.api.app.BeanConfiguration.afterApplicationStart(BeanConfiguration.java:66) at org.apache.camel.spring.boot.RoutesCollector.onApplicationEvent(RoutesCollector.java:226) at org.apache.camel.spring.boot.RoutesCollector.onApplicationEvent(RoutesCollector.java:54) at org.springframework.context.event.SimpleApplicationEventMulticaster.doInvokeListener(SimpleApplicationEventMulticaster.java:172) at org.springframework.context.event.SimpleApplicationEventMulticaster.invokeListener(SimpleApplicationEventMulticaster.java:165) at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:139) at org.springframework.context.support.AbstractApplicationContext.publishEvent(AbstractApplicationContext.java:393) at org.springframework.context.support.AbstractApplicationContext.publishEvent(AbstractApplicationContext.java:347) at org.springframework.context.support.AbstractApplicationContext.finishRefresh(AbstractApplicationContext.java:883) at org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.finishRefresh(EmbeddedWebApplicationContext.java:144) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:546) at org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.refresh(EmbeddedWebApplicationContext.java:122) at org.springframework.boot.SpringApplication.refresh(SpringApplication.java:693) at org.springframework.boot.SpringApplication.refreshContext(SpringApplication.java:360) at org.springframework.boot.SpringApplication.run(SpringApplication.java:303) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1118) at org.springframework.boot.SpringApplication.run(SpringApplication.java:1107) at com.haufe.ssmp.sfdc.api.Application.main(Application.java:12) Due to my complex use case, i would like to start one specific route manually and not use the autoconfiguration and autostart from camelcontext. I do this in my configuration class by over riding the before application start and after application start methods. @Configuration class BeanConfiguration implements CamelContextConfiguration { private static final Logger log = LoggerFactory.getLogger(BeanConfiguration.class); @Override public void beforeApplicationStart(CamelContext camelContext) { camelContext.setPackageScanClassResolver(new FatJarPackageScanClassResolver()); camelContext.resolveDataFormat("json-jackson"); } @Autowired SalesforceComponent sfdcComp; @Override public void afterApplicationStart(CamelContext camelContext) { try { sfdcComp.start(); camelContext.startRoute("salesforce-versions"); Route theRoute = camelContext.getRoute("salesforce-versions"); Endpoint ep = theRoute.getEndpoint(); Exchange exchange = ep.createExchange(); ProducerTemplate template = exchange.getContext().createProducerTemplate(); DefaultExchange o = (DefaultExchange) template.request(ep, new Processor() { @Override public void process(Exchange exchange) throws Exception { // TODO Auto-generated method stub } }); Object result = o.getOut().getBody(); if(result == null && !(result instanceof ArrayList)) throw new Exception("No Salesforce version, login failed."); ArrayList theList = (ArrayList) result; if(theList.size() <= 1) throw new Exception("No Salesforce version got, login failed."); log.debug("Connection to salesforce successfully established:"); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); throw new RuntimeException("No Connection to salesforce"); } } In this code, i saw during my debugging that it was able to start the routes in camelcontext object and get the endpoints, however with version 2.20.0 I see my routes are not added to the camelcontext and no routes are started. Could anyone help me here to trouble shoot this issue ? Thanks in advance -- Dicken George
