我正在尝试将Alexa与Spring Boot webservice连接，但我面临的问题很少。 servlet不仅仅在服务器上工作，它会抛出404但在本地我得到的500和400与我用于servlet的URL相同。

请在setAmazonProperties()
SpringApplication.run(VocabBrawlAlexaApplication.class, args);方法
public static void main(String[] args) {
LOGGER.info("Info Message Logged !!!");
setAmazonProperties();
SpringApplication.run(VocabBrawlAlexaApplication.class, args);
LOGGER.info("Info Message Logged asdfsa !!!");
}
