Design Issues
DI 1: 20170712: AAI Cert required for HTTPS REST calls
Use postman for adhoc rest calls - but if you want to code up call chains or hammer an endpoint use Spring RestController or the Rest client in JAX-RS 2.0
Calls to AAI such as the following require both the authentication header and an imported certificate. When running Postman - because it is a Chrome app - this is a simple case of loading a REST url in the browser and importing the certificate after an authentication challenge (AAI:AAI). However for a java client like a JAX-RS 2.0 client we need the certificate in a keystore (the default or a specially defined one).
Below we import the cert into the default keystore. Where did I get the cert? by extracting it from Firefox - however it is in the code base - looking it up

obrienbiometrics:onap michaelobrien$ ls $JAVA_HOME/jre/lib/security/cacerts
/Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/jre/lib/security/cacerts
sudo keytool -import -trustcacerts -alias aai -file /Users/michaelobrien/Dropbox/_amdocs/config/certs/aai/aaiapisimpledemoopenecomporg.cer -keystore $JAVA_HOME/jre/lib/security/cacerts
Running an https rest target using this certificate - if the cert is in a default keystore - you dont need to define it.

// require: cert, username, password, headers(X-FromAppId,Accept), Authenticator
public String run(boolean isSSL, String url, String port, String path) {String record = null;
Client client = null;
WebTarget latestTarget = null;
WebTarget rootTarget = null;
if(isSSL) {
SslConfigurator sslConfig = SslConfigurator.newInstance();
SSLContext sslContext = sslConfig.createSSLContext();
HostnameVerifier verifier = new HostnameVerifier() {
public boolean verify(String hostname, SSLSession sslSession) {
return true; // TODO: security breach
}};
client = ClientBuilder.newBuilder().sslContext(sslContext).hostnameVerifier(verifier).build();
client.register(new Authenticator("AAI","AAI"));
} else {
client = ClientBuilder.newClient();
}
rootTarget = client.target(url);
latestTarget = rootTarget.path(path);
try {
try { Thread.sleep(1); } catch (InterruptedException ie) { Thread.currentThread().interrupt(); }
record = finalTarget.request()
.header("X-FromAppId", "AAI").header("Accept", "application/json")
.get(String.class);

DI 2: 20170712: Spring Boot Backend Framework
Instead of using a full Tomcat deployment server - we will use an embedded Jetty container.
