Overview

RESTful web services are built to work best on the Web. Representational State Transfer (REST) is an architectural style that specifies constraints, such as the uniform interface, that if applied to a web service induce desirable properties, such as performance, scalability, and modifiability, that enable services to work best on the Web. In the REST architectural style, data and functionality are considered resources and are accessed using Uniform Resource Identifiers (URIs), typically links on the Web. The resources are acted upon by using a set of simple, well-defined operations. The REST architectural style constrains an architecture to a client/server architecture and is designed to use a stateless communication protocol, typically HTTP. In the REST architecture style, clients and servers exchange representations of resources by using a standardized interface and protocol. (as defined in https://docs.oracle.com/javaee/6/tutorial/doc/gijqy.html). 

Technology and Security

The services employ an implementation of the SpringBoot technology which allows each service to run standalone instead of running inside an applications server such as Apache Tomcat.

These services will use SSL and require a certificate.  Clients will either need a public key or must trust all certificates.

Configuration

The following directories are required on the host server

  • /srv/uconn_configs/webapi
  • /srv/uconn_configs/webapi/config
  • /srv/uconn_configs/webapi/security

Common properties files contained in the /config directory.  Key stores necessary to security the services are contained in the /security directory.

The initial configuration is as follows:

  • /srv/uconn_configs/webapi/config/db-config.properties
  • /srv/uconn_configs/webapi/config/ldap-config.properties
  • /srv/uconn_configs/webapi/config/ldap-client.properties
  • /srv/uconn_configs/webapi/config/affiliations.properties
  • /srv/uconn_configs/webapi/config/security.properties
  • /srv/uconn_configs/webapi/security/aewebapi.jks

Each service resides in a directory under the ../webapi directory for  example, the first rest service is financialwebapis it resides in /srv/uconn_configs/webapi/financialwebapis directory.  This contains the jar file, start and stop scripts and a /logs directory for the application log.
