This article comprehensively examines the common error "No subject alternative names matching IP address ... found" encountered in Java applications when establishing SSL/TLS connections with self-signed certificates. It begins by analyzing the root cause of the exception: the absence of matching Subject Alternative Names (SAN) for the target IP address in the certificate. By comparing the certificate validation mechanisms between web browsers and the Java Virtual Machine (JVM), it explains why the same certificate works in browsers but fails in Java. The core section presents two primary solutions: modifying the certificate generation process to include the IP address as an IPAddress-type SAN, and bypassing strict hostname verification through a custom HostnameVerifier. The article also discusses the security implications and applicable scenarios of these methods, providing detailed code examples and configuration steps to help developers fundamentally resolve IP address validation issues.
