Above dependencies I have added, which is not helping.

package com.xxx.yyy.config;

import com.mongodb.MongoClient;
import com.mongodb.MongoClientOptions;
import com.mongodb.MongoClientURI;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.mongodb.config.AbstractMongoConfiguration;

@Configuration
public class MongoDbConfig extends AbstractMongoConfiguration {

    public MongoClientOptions.Builder mongoClientOptionsBuilder(){
        String javaPath = System.getProperty("java.home");
        System.setProperty ("javax.net.ssl.keyStore",javaPath+"/lib/security/cacerts");
        System.setProperty ("javax.net.ssl.keyStorePassword","changeit");
        System.out.println(javaPath);
        System.out.println(System.getProperty("javax.net.ssl.keyStore"));
        MongoClientOptions.Builder builder = MongoClientOptions.builder();
//        MongoClientOptions options=builder.sslEnabled(true).build();
        return builder;
    }


    MongoClientURI uri = new MongoClientURI("my_mongo_url",
            mongoClientOptionsBuilder().sslEnabled(true));

    @Override
    public MongoClient mongoClient() {
        return new MongoClient(uri);
    }

    @Override
    protected String getDatabaseName() {
        return "MY_DATABASE_NAME";
    }
}

Please check and thanks in advance
