我在ssl支持下构建了spring-boot可执行文件大战。我的application.properties文件是：

server.port = 8443
server.ssl.key-store = classpath:keystore.jks
server.ssl.key-store-password = secret
server.ssl.key-password = another-secret

WAR文件包含“ keystore.jks”文件。但是我得到一个奇怪的例外：

org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.boot.context.embedded.EmbeddedServletContainerException: Could not find key store classpath:keystore.jks



Caused by: java.io.FileNotFoundException: class path resource [keystore.jks] cannot be resolved to absolute file path because it does not reside in the file system: jar:file:/D:/projects/vi3na/vi3na.web/target/vi3na.war!/WEB-INF/classes!/keystore.jks

什么符号“！” 在路径’D：/projects/vi3na/vi3na.web/target/vi3na.war！/ WEB-INF /
classes！/keystore.jks’中的意思
