到目前为止，我已经设置了一个Spring Framework 5项目。需要为某些功能启用HTTPS，因此遵循教程。当前使用以下命令在服务器上生成证书和密钥：
keytool -genkeypair -alias tomcat -storetype PKCS12 -keyalg RSA -keysize 2048 -keystore keystore.p12 -validity 365000
然后我将此密钥库导入我的资源文件夹并使用以下属性：
server.ssl.key-store= classpath:keystore.p12
server.ssl.key-store-password= myPassword
server.ssl.key-store-type= PKCS12
server.ssl.key-alias= tomcat
server.port= 8444
我还设置了从HTTP到HTTPS的重定向，具有以下配置：
@Bean
public ServletWebServerFactory servletContainer() {
TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {
@Override
protected void postProcessContext(Context context) {
SecurityConstraint securityConstraint = new SecurityConstraint();
securityConstraint.setUserConstraint("CONFIDENTIAL");
SecurityCollection collection = new SecurityCollection();
collection.addPattern("/*");
securityConstraint.addCollection(collection);
context.addConstraint(securityConstraint);
}
};
tomcat.addAdditionalTomcatConnectors(redirectConnector());
return tomcat;
}
private Connector redirectConnector() {
Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
connector.setScheme("http");
connector.setPort(8182);
connector.setSecure(false);
connector.setRedirectPort(8444);
return connector;
}
从我的IDE本地运行或运行已编译的.jar时，它工作正常。然而，当我尝试在我的服务器上运行它（一个以前工作正常的本地运行的Synology NAS）时，我在Firefox上遇到以下错误时尝试到达地址（https://192.168.10.10:8444）时出错：SSL_ERROR_NO_CYPHER_OVERLAP和chrome ERR_SSL_VERSION_OR_CIPHER_MISMATCH。我找到了答案，但我没有找到任何改变这个问题结果的解决方案。

老问题，但我有同样的问题。 Synology站使用旧的JDK（1.8.0_161）。更新到最新的1.8（1.8.0_202-b08）后，一切正常。
典型的错误可能是您的* .p12文件无法打包到已部署的工件中。
你检查过你的罐子里有它吗？
