Essentially I have created two entry points to the same service __createUser() on the same interface class UserRestService. I am going to repeat this pattern for all the other services I want to expose. This is a simple case of refactoring the interfaces methods.
The __createUser() method looks like this
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
private Response __createUser( User usr )
{
Response resp;
try
{
DBConnector connector = DBConnector.getConnector();
connector.loadAndConnect();
UserHandler.getLoader().addUser(connector.getConnection(), usr);
resp = Response.status(200).entity(usr).build();
} catch (IOException ex)
{
resp = Response.status(200).entity(new SimpleErrorMessage("CANNOT ADD USER - SERVER PROBLEM")).build();
Logger.getLogger(UserRestServices.class.getName()).log(Level.SEVERE, null, ex);
} catch (ResponseException ex)
{
Logger.getLogger(UserRestServices.class.getName()).log(Level.SEVERE, null, ex);
resp = Response.status(200).entity(ex.getResponse()).build();
} catch (SQLException ex)
{
resp = Response.status(200).entity(new SimpleErrorMessage(usr.getUserID() + " CANNOT BE ADDED - ALREADY EXIST")).build();
Logger.getLogger(UserRestServices.class.getName()).log(Level.SEVERE, null, ex);
}
return resp;

I didn't use Java 8 exception multi catch statements as I wanted to report different messages back to the client.
