SSL can be configured declaratively by setting various properties.
You can set either javax.net.ssl.trustStore to configure
JVM-wide SSL settings or spring.cloud.vault.ssl.trust-store
to set SSL settings only for Spring Cloud Vault Config.
spring.cloud.vault: ssl: trust-store: classpath:keystore.jks trust-store-password: changeit
trust-store sets the resource for the trust-store. SSL-secured Vault
communication will validate the Vault SSL certificate with the specified
trust-store.trust-store-password sets the trust-store passwordPlease note that configuring spring.cloud.vault.ssl.* can be only
applied when either Apache Http Components or the OkHttp client
is on your class-path.
