I'm trying to convert a simple Spring Boot app into a war file for deployment to my tomcat server but I keep on getting this error:
Caused by: org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'errorPageFilter': Initialization of bean failed; nested exception is java.lang.ClassCastException: org.springframework.boot.context.web.ErrorPageFilter cannot be cast to org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory
This Spring Boot app works perfectly when I run it as a jar but if I create a war, it gives me errors. As far as I can tell, I followed the Spring guide for this perfectly: http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file
This is my application class:
@Configuration
@EnableWebMvc
@ComponentScan({"XXX"})
@EnableAutoConfiguration
@EnableConfigurationProperties
@SpringBootApplication
@EnableAsync
public class Application extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
This is my build.gradle:
buildscript {

It does say that the error occurred in my java file called ContainerConfiguration.java:
@Configuration
public class ContainerConfiguration {
@Bean
EmbeddedServletContainerCustomizer containerCustomizer(
//all taken from the application.properties file
@Value("${keystore.file}") String keystoreFile,
@Value("${server.port}") final String serverPort,
@Value("${keystore.pass}") final String keystorePass)
throws Exception {
// This is boiler plate code to setup https on embedded Tomcat
// with Spring Boot:
final String absoluteKeystoreFile = new File(keystoreFile)
.getAbsolutePath();
return new EmbeddedServletContainerCustomizer() {
@Override
public void customize(ConfigurableEmbeddedServletContainer container) {
TomcatEmbeddedServletContainerFactory tomcat = (TomcatEmbeddedServletContainerFactory) container;
tomcat.addConnectorCustomizers(connector -> {
connector.setPort(Integer.parseInt(serverPort));
connector.setSecure(true);
connector.setScheme("https");
Http11NioProtocol proto = (Http11NioProtocol) connector
.getProtocolHandler();
proto.setSSLEnabled(true);
proto.setKeystoreFile(absoluteKeystoreFile);
proto.setKeystorePass(keystorePass);
proto.setKeystoreType("JKS");
proto.setKeyAlias("abcd");
});
}
};
}
}
The error is on this line:
tomcat.addConnectorCustomizers(connector -> {
connector.setPort(Integer.parseInt(serverPort));
connector.setSecure(true);
connector.setScheme("https");
I don't get how errorPageFilter is casted to TomcatEmbeddedServletContainerFactory?
Does anyone know how I can fix this error?
EDIT:
I have also create a simple SpringBoot test app to demonstrate this error as well , you can find it here: https://github.com/Winghin2517/testSpringBootTomcat
There are only two classes in the github repo:
- ContainerConfiguration - where the offensive class is sitting.
- DemoApplication - the main method sits here
If you comment out the ContainerConfiguration and build a war file then upload it to a tomcat server, it works perfectly. If you uncomment out the ContainerConfiguration and build the war file and upload it, you will get the error.
