Dati di primavera mongodb, come impostare SSL?

Se vuoi solo connettere la tua app di avvio primaverile con mongodb, puoi utilizzare keyStore e trustStore con codice java. Quindi non devi aggiungere il tuo certificato tramite riga di comando. Se stai usando Cloud Foundry puoi connettere la tua app con mongodbServices e poi hai tutte le credenziali di cui hai bisogno in System.getEnv("VCAP_SERVICES").

@Configuration
public class MongoConfiguration extends AbstractMongoConfiguration {
    private static Log logger = LogFactory.getLog(MongoConfiguration.class);
    @Value("${spring.data.mongodb.database}")
    private String defaultDatabase; //database you want to connect
    private String host;
    private int port;
    private String authenticationDb; //usually admin
    private String username;
    private char[] password;
    private String certificateDecoded; //your CA Certifcate decoded (starts with BEGIN CERTIFICATE)

    public MongoConfiguration() {
        //method for credentials initialization
    }

    //you can't set replicaset=replset in mongooptions so if you want set replicaset, you have to use 
    // customEditorConfigurer in combintaion with class that implementsPropertyEditorRegistrar
    @Bean
    public static CustomEditorConfigurer customEditorConfigurer(){
        CustomEditorConfigurer configurer = new CustomEditorConfigurer();
        configurer.setPropertyEditorRegistrars(
                new PropertyEditorRegistrar[]{new ServerAddressPropertyEditorRegistrar()});

    }

            keyStore.setCertificateEntry("caCert", caCert);

            trustManagerFactory.init(keyStore);
