如何使用Spring RestTemplate禁用SSL证书检查？
如何使用Spring RestTemplate禁用SSL证书检查？
提问于 2014-05-06 21:27:02
我正在尝试编写一个集成测试，其中我们的测试使用简单启动一个嵌入式HTTPS服务器。我keytool并能够使用浏览器访问服务器(特别是Chrome，我确实收到了关于自签名证书的警告)。
然而，当我尝试使用弹簧RestTemplate连接时，我得到了一个ResourceAccessException：
org.springframework.web.client.ResourceAccessException: I/O error on GET request for "https://localhost:8088":sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target; nested exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

private static final HostnameVerifier PROMISCUOUS_VERIFIER = ( s, sslSession ) -> true;我已经在全球范围和RestTemplate本身上设置了它：
HttpsURLConnection.setDefaultHostnameVerifier( PROMISCUOUS_VERIFIER );...and在RestTemplate本身上：
final RestTemplate restTemplate = new RestTemplate();
restTemplate.setRequestFactory( new SimpleClientHttpRequestFactory() {
@Override
protected void prepareConnection(HttpURLConnection connection, String httpMethod) throws IOException {
if(connection instanceof HttpsURLConnection ){
((HttpsURLConnection) connection).setHostnameVerifier(PROMISCUOUS_VERIFIER);
}
super.prepareConnection(connection, httpMethod);
}
});然而，我仍然得到上述错误。我怎么才能绕过它？
- 在单元测试之外本地安装证书不是一个选项，因为它需要手动安装在每台dev机器和构建服务器上，并且会导致大量的繁文缛节。
- 我们需要SSL，因为我们正在测试位于
RestTemplate之上的库，并且我们正在正确地配置它。
我使用的是Java 8(但可以使用7)和Spring4.0.3。
