是否可以附加证书而不在sslcontext的信任存储中存储
这是我的代码，而运行我的代码它不是x509格式的例外，我得到

@Bean(name="custRest")
    @Primary
    public RestTemplate restTemplate() throws Exception {
        char[] password = "password".toCharArray();

        SSLContext sslContext = SSLContextBuilder
                .create()
                .loadTrustMaterial(ResourceUtils.getFile("C:\\test\\test.der"), password,
                        new TrustSelfSignedStrategy())
                .build();

        HttpClient client = HttpClients.custom().setSSLContext(sslContext).build();
        return new RestTemplateBuilder().requestFactory(new HttpComponentsClientHttpRequestFactory(client))
                .build();
    }
