Specifying trust store information in spring boot application properties

Question

I am using springBootVersion 1 2 0 RELEASE  I m trying to have my keystore and truststore configured through application properties   When I add the following settings  I can get the keystore to work  but not the truststore   server ssl key-store classpath foo jks server ssl key-store-password password server ssl key-password password server ssl trust-store classpath foo jks server ssl trust-store-password password   However  if I add the truststore through gradle   bootRun       jvmArgs      -Djavax net ssl trustStore c   foo jks    -Djavax net ssl trustStorePassword password       it works just fine   Has anyone used the application properties for trust stores

I have the same problem  I ll try to explain it a bit more in detail   I m using spring-boot 1 2 2-RELEASE and tried it on both Tomcat and Undertow with the same result   Defining the trust-store in application yml like   server    ssl      trust-store  path-to-truststore        trust-store-password  my-secret-password      Doesn t work  while     java -Djavax net debug ssl -Djavax net ssl trustStore path-to-truststore    -Djavax net ssl trustStorePassword my-secret-password    -jar build libs   jar     works perfectly fine   The easiest way to see the difference at rutime is to enable ssl-debug in the client  When working  i e  using -D flags  something like the following is written to the console  during processing of the first request    trustStore is  path-to-truststore    trustStore type is   jks trustStore provider is   init truststore adding as trusted cert    Subject  C      ST      O      OU      CN       Issuer   C      ST      O      OU      CN       Algorithm  RSA  Serial number  0x4d2   Valid from Wed Oct 16 17 58 35 CEST 2013 until Tue Oct 11 17 58 35 CEST 2033   Without the -D flags I get   trustStore is   Library Java JavaVirtualMachines jdk1 8 0 11 jdk Contents Home jre lib security cacerts trustStore type is   jks trustStore provider is   init truststore adding as trusted cert       one for each CA-cert in the defult truststore       and when performing a request I get the exception   sun security validator ValidatorException  PKIX path building failed  sun security provider certpath SunCertPathBuilderException  unable to find valid certification path to requested target   Hope it helps to understand the issue better

In a microservice infrastructure  does not fit the problem  I know     you must not use   server    ssl      trust-store  path-to-truststore        trust-store-password  my-secret-password      Instead the ribbon loadbalancer can be configuered   ribbon     TrustStore  keystore jks   TrustStorePassword   example   ReadTimeout  60000   IsSecure  true   MaxAutoRetries  1   Here https   github com rajaramkushwaha https-zuul-proxy-spring-boot-app you can find a working sample  There was also a github discussion about that  but I didn t find it anymore

If you execute your Spring Boot application as a linux service  e g  init d script or similar   then you have the following option as well  Create a file called yourApplication conf and put it next to your executable war jar file  It s content should be something similar   JAVA OPTS   -Djavax net ssl trustStore path-to-your-trustStore-file -Djavax net ssl trustStorePassword yourCrazyPassword

I had the same problem with Spring Boot  Spring Cloud  microservices  and a self-signed SSL certificate  Keystore worked out of the box from application properties  and Truststore didn t   I ended up keeping both keystore and trustore configuration in application properties  and adding a separate configuration bean for configuring truststore properties with the System    Configuration public class SSLConfig        Autowired     private Environment env        PostConstruct     private void configureSSL             set to TLSv1 1 or TLSv1 2       System setProperty  https protocols    TLSv1 1             load the  javax net ssl trustStore  and          javax net ssl trustStorePassword  from application properties       System setProperty  javax net ssl trustStore   env getProperty  server ssl trust-store            System setProperty  javax net ssl trustStorePassword  env getProperty  server ssl trust-store-password

When everything sounded so complicated  this command worked for me   keytool -genkey -alias foo -keystore cacerts -dname cn test -storepass changeit -keypass changeit   When a developer is in trouble  I believe a simple working solution snippet is more than enough for him  Later he could diagnose the root cause and basic understanding related to the issue

I was also having the same issue with Spring Boot and embedded Tomcat   From what I understand these properties only set the Tomcat configuration parameters  According to the Tomcat documentation this is only used for Client authentication  i e  for two-way SSL  and not for verifying remote certificates      truststoreFile - The trust store file to use to validate client certificates    https   tomcat apache org tomcat-8 0-doc config http html  In order to configure the trust store for HttpClient it largely depends on the HttpClient implementation you use  For instance for RestTemplate by default Spring Boot uses a SimpleClientHttpRequestFactory based on standard J2SE classes like java net HttpURLConnection   I ve come up with a solution based on the Apache HttpClient docs and these posts  http   vincentdevillers blogspot pt 2013 02 configure-best-spring-resttemplate html http   literatejava com networks ignore-ssl-certificate-errors-apache-httpclient-4-4   Basically this allows for a RestTemplate bean that only trusts certificates signed by the root CA in the configured truststore    Configuration public class RestClientConfig           e g  Add http client ssl trust-store classpath ssl truststore jks to application properties      Value    http client ssl trust-store        private Resource trustStore        Value    http client ssl trust-store-password        private char   trustStorePassword        Value    http client maxPoolSize        private Integer maxPoolSize         Bean     public ClientHttpRequestFactory httpRequestFactory             return new HttpComponentsClientHttpRequestFactory httpClient                 Bean     public HttpClient httpClient                 Trust own CA and all child certs         Registry lt ConnectionSocketFactory gt  socketFactoryRegistry   null          try               SSLContext sslContext   SSLContexts                      custom                        loadTrustMaterial trustStore getFile                                trustStorePassword                       build                    Since only our own certs are trusted  hostname verification is probably safe to bypass             SSLConnectionSocketFactory sslSocketFactory   new SSLConnectionSocketFactory sslContext                      new HostnameVerifier                               Override                         public boolean verify final String hostname                                  final SSLSession session                                return true                                                         socketFactoryRegistry   RegistryBuilder  lt ConnectionSocketFactory gt create                        register  http   PlainConnectionSocketFactory getSocketFactory                         register  https   sslSocketFactory                       build                          catch  Exception e                  TODO  handle exceptions             e printStackTrace                       PoolingHttpClientConnectionManager connectionManager   new PoolingHttpClientConnectionManager socketFactoryRegistry           connectionManager setMaxTotal maxPoolSize              This client is for internal connections so only one route is expected         connectionManager setDefaultMaxPerRoute maxPoolSize           return HttpClientBuilder create                    setConnectionManager connectionManager                   disableCookieManagement                    disableAuthCaching                    build                Bean     public RestTemplate restTemplate             RestTemplate restTemplate   new RestTemplate            restTemplate setRequestFactory httpRequestFactory             return restTemplate                And then you can use this custom Rest client whenever you need to  e g     Autowired private RestTemplate restTemplate   restTemplate getForEntity        This assumes your trying to connect to a Rest endpoint  but you can also use the above HttpClient bean for whatever you want

If you are in Spring  try just add properties for it  use needed properties   and it should work for total JVM  javax    net      ssl        key-store-password    KEYSTORE SECRET        key-store-type  PKCS12       trust-store-password    TRUSTSTORE SECRET        trust-store-type  PKCS12

In case if you need to make a REST call you can use the next way   This will work for outgoing calls through RestTemplate   Declare the RestTemplate bean like this    Configuration public class SslConfiguration        Value    http client ssl trust-store        private Resource keyStore       Value    http client ssl trust-store-password        private String keyStorePassword        Bean     RestTemplate restTemplate   throws Exception           SSLContext sslContext   new SSLContextBuilder                    loadTrustMaterial                          keyStore getURL                            keyStorePassword toCharArray                     build            SSLConnectionSocketFactory socketFactory                    new SSLConnectionSocketFactory sslContext           HttpClient httpClient   HttpClients custom                    setSSLSocketFactory socketFactory  build            HttpComponentsClientHttpRequestFactory factory                    new HttpComponentsClientHttpRequestFactory httpClient           return new RestTemplate factory             Where http client ssl trust-store and http client ssl trust-store-password points to truststore in JKS format and the password for the specified truststore   This will override the RestTemplate bean provided with Spring Boot and make it use the trust store you need
