Google Geocoding SSL Handshake Exception

问题

I'm having trouble with my java truststore. I would be very grateful if someone could help me with this problem. I've built a micro service with Spring-Boot for geocoding in which I want to use the Google Geocoding API. Unfortunately, I'm getting a SSL Handshake Exception, despite the fact that I've downloaded the Google Authority G3 certificate via Open SSL, imported it into a new truststore file, and included this truststore file into my code.

Edit: This is the precise error message I'm getting:

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 targe

Here is my code:

The truststore entry in my application properties:

server.ssl.trust-store=src\\main\\java\\de\\projectname\\microservicename\\geographical\\files\\newTrustStore

server.ssl.trust-store-password=changeit

Edit2:

This is the keytool command I used to import the Google certificate in my truststore and save it in my microservice directory along the way (couple of directories have been renamed for data security reasons):

keytool -importcert C:\Users\jdoe\IdeaProjects\microservice\src\main\java\de\projectname\microservicename\geographical\files\googleapicert -keystore C:\Users\jdoe\IdeaProjects\microservice\src\main\java\de\projectname\projecttitle\geographical\files\truststore.jks -alias "jdoe"

Edit 3:

This is what my trust store looks like:

My Geocoding class:

public class Geocoding {
@Value("${google.geocoding.api}")
private String googleAPIKey;

@Value("${google.geocoding.url}")
private String url;

final static Logger logger = Logger.getLogger(Geocoding.class);

private GeoApiContext context = new GeoApiContext.Builder()
        .apiKey(googleAPIKey)
        .build();

@ApiModelProperty
private String langauge;

private Gson gson = new GsonBuilder().setPrettyPrinting().create();

public Geocoding() {
}

public Geocoding(String googleAPIKey, String url) {
    this.googleAPIKey = googleAPIKey;
    this.url = url;
    this.context = new GeoApiContext.Builder().apiKey(googleAPIKey).build();
}

public String getLangauge() {
    return langauge;
}

public void setLangauge(String langauge) {
    if (langauge.length() > 1) {
        IllegalArgumentException ex = new IllegalArgumentException("illegal representation of a language code");
        throw ex;
    }
    this.langauge = langauge;
}

public String generateOutput(String request) {
    String output = url;
    request = request.replaceAll("\\s+", "+");
    List<String> deserializedString = Arrays.asList(request.split("\\s*,\\s*"));
    output = output.concat(deserializedString.get(0))
            .concat(",").concat(deserializedString.get(1)).concat(",")
            .concat(deserializedString.get(2)).concat("&key=").concat(googleAPIKey);
    return output;
}

public Address geoCodingResult(String address) throws Exception {

        GeocodingResult[] results = GeocodingApi.geocode(context, address).await(); //The application throws an SSL handshake exception right here

    }
}

These are the dependencies I've included in Gradle for Geocoding:

//Google Geocoding
compile 'com.google.maps:google-maps-services:0.2.8'
compile 'org.slf4j:slf4j-nop:1.7.25'
compile 'com.squareup.okhttp3:okhttp:3.10.0'

I've already checked both the Google API key and the geocoding url multiple times and they both seem to be correct, so I'm ruling out that that's the issue. I've also looked into the "newTrustStore" file with keytools and it does in fact have the Google Authority G3 certificate in it.

Help is much appreciated!

回答1:

I faced same issue while using com.google.maps:google-maps-services on OpenJDK 10 which does not trust Google Internet Authority G3 for some reason.

To fix this it's better to import missing certificate to the system-wide keystore (usually found in $JAVA_HOME/lib/security/cacerts) using keytool:

wget http://pki.goog/gsr2/GTSGIAG3.crt
keytool -import -alias GTSGIAG3 -file GTSGIAG3.crt -keystore $JAVA_HOME/lib/security/cacerts

Then enter the password if prompted (the default is changeit).

If you are using Docker, you can import missing certificate using a following command:

FROM openjdk:10-jre-slim

RUN apt-get -qqy update \
    && apt-get -qqy --no-install-recommends install wget \
    && wget http://pki.goog/gsr2/GTSGIAG3.crt \
    && yes | keytool -import -alias GTSGIAG3 -file GTSGIAG3.crt -keystore $JAVA_HOME/lib/security/cacerts -storepass 'changeit' \
    && rm GTSGIAG3.crt \
    && apt-get -qqy purge wget \
    && rm -rf /var/lib/apt/lists/* /var/cache/apt/*

i am wondering: if you are in maven, then resources in

 src/main/java/....

will NOT end up in the jar. that directory is for classes only. to have it in the output, put the truststore in

 src/main/resources

also, you will probably have to adjust the path. it might be something like:

classpath:/path/within/the/resources/folder/trustStore

or just:

path/within/the/resources/folder/trustStore
