应用错误收集

我在运行underow和spring-boot 1.4时遇到 NullPointerException 。

如果您使用

运行joinfaces-example，则会看到此错误

java -jar target / joinfaces-example-2.1.3-SNAPSHOT.jar

我意识到如果我在IDE（NetBeans）中调试项目，则不会发生错误。

此外，当我将spring boot升级到1.4时，会出现此错误。如果我将jsf-spring-boot-parent版本更改为使用spring boot 1.3版本的2.0.0，则不会发生错误。

未激活StartupServletContextListener时可能会发生此错误。它由UndertowMyfacesSpringBootAutoConfiguration创建。 Debug说它被激活了：

   UndertowMyfacesSpringBootAutoConfiguration matched
      - @ConditionalOnClass classes found: io.undertow.Undertow,org.apache.myfaces.webapp.StartupServletContextListener (OnClassCondition)
