我只是尝试使用 Jersey 1.16 并在我的应用程序中添加 https 支持。使用Jersey https_grizzly 示例作为参考，我在 SecurityFilter.authority() 中添加了一行代码
final Principal principal = request.getSecurityContext().getUserPrincipal();
if (principal != null){
System.out.println("principal: " + principal.getName());
} else {
System.out.println("No principal") ;
}
然后我尝试使用 https 启动服务器并将 setNeedClientAuth 设置为 false 以避免通过更改 startServer() 中的 Server.java 来使用客户端证书：
webServer = GrizzlyServerFactory.createHttpServer(
getBaseURI(),
null,
true,
new SSLEngineConfigurator(sslContext).setClientMode(false).setNeedClientAuth(false)
);
setNeedClientAuth(false) 中的布尔参数最初为 true，以便请求客户端证书。我认为通过这种方式，我的应用程序可以适应有证书和没有证书的客户。如果没有证书，getUserPrincipal() 可能会返回 null，以便我知道这是一个匿名用户。不幸的是，在这种情况下，系统引发如下异常并且客户端没有收到任何信息：
java.lang.IllegalStateException: Handshake is not completed!

为什么在这种情况下我不能使用 getUserPrincipal() ？有人知道吗？谢谢你。
