• AWS Prerequisites

  You need to generate a truststore.jks file and application.conf

  Follow Link Amazon Keyspaces (for Apache Cassandra)

  just do it step by step

  1. If you have not already done so, sign up for an AWS account by following the steps at Signing up for AWS.

  2. Create credentials by following the steps at Creating credentials to access Amazon Keyspaces programmatically.

     • Download the AWS CLI at http://aws.amazon.com/cli .

     • Follow the instructions for Installing the AWS CLI and Configuring the AWS CLI in the AWS Command Line Interface User Guide.

     • Using the AWS CLI, run the following command to generate service-specific credentials for the user alice, so that she can access Amazon Keyspaces.

       
           aws iam create-service-specific-credential \
           --user-name alice \
           --service-name cassandra.amazonaws.com
       

     The output looks like the following.

     
         {
             "ServiceSpecificCredential":
             {
                 "CreateDate": "2019-10-09T16:12:04Z",
                 "ServiceName": "cassandra.amazonaws.com",
                 "ServiceUserName": "alice-at-111122223333",
                 "ServicePassword": "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY",
                 "ServiceSpecificCredentialId": "ACCAYFI33SINPGJEBYESF",
                 "UserName": "alice",
                 "Status": "Active"
             }
         }
     

  3. Create a JKS trust store file.

     1. Download the Starfield digital certificate using the following command and save sf-class2-root.crt locally or in your home directory.

        
            curl https://certs.secureserver.net/repository/sf-class2-root.crt -O
        

     2. Convert the Starfield digital certificate into a trustStore file.

        
            openssl x509 -outform der -in sf-class2-root.crt -out temp_file.der
            keytool -import -alias cassandra -keystore cassandra_truststore.jks -file temp_file.der
        

        In this step, you need to create a password for the keystore and trust this certificate. The interactive command looks like this.

        
            Enter keystore password:
            Re-enter new password:
            Owner: OU=Starfield Class 2 Certification Authority, O="Starfield Technologies, Inc.", C=US
            Issuer: OU=Starfield Class 2 Certification Authority, O="Starfield Technologies, Inc.", C=US
            Serial number: 0
            Valid from: Tue Jun 29 17:39:16 UTC 2004 until: Thu Jun 29 17:39:16 UTC 2034
            ..........
            ...
            Trust this certificate? [no]:  y
        

  4. Create an application.conf file

     
         datastax-java-driver {
             basic.request.consistency = LOCAL_QUORUM
             basic.contact-points = ["yours"]
             advanced.auth-provider{
               class = PlainTextAuthProvider
               username = "yours"
               password = "yours"
             }
             basic.load-balancing-policy {
               local-datacenter = "yours ex: ap-northeast-1"
             }
             advanced.ssl-engine-factory {
               class = DefaultSslEngineFactory
               truststore-path = "./src/main/resources/cassandra_truststore.jks"
               truststore-password = ""
               hostname-validation = false
             }
         }
     

• Setup your Project

  put application.conf and cassandra_truststore.jks in resources folder

  
      spring:
        main:
          allow-bean-definition-overriding: true
        http:
          encoding:
            force: true
        jpa:
          open-in-view: true
          properties:
            hibernate:
              dialect: org.hibernate.dialect.MySQL5Dialect
        datasource:
          url: jdbc:mysql://localhost:3306/animal_sys
          username: root
          password: password
          driver-class-name: com.mysql.cj.jdbc.Driver
        data:
          cassandra:
            config: classpath:application.conf  // if use spring-boot-starter-data-cassandra. it works.
            ssl: true
            keyspace-name: skskeyspace1
            port: 9142
            contact-points: cassandra.ap-northeast-1.amazonaws.com
            username:
            password:
      ssl:
        trustStore:
          trustStoreLocation: /cassandra_truststore.jks
          trustStorePassword:
  

• Setup Project POM

  more tips for pom.xml

  if you want use mysql comment out follows:

  
          <--
          <dependency>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-data-jpa</artifactId>
          </dependency>
          -->
      
  

  if you want use spring cassandra auto configure with spring.data.cassandra in properties, add follows

  
          <dependency>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-data-cassandra</artifactId>
          </dependency>
