+# README - slf4j-reference
+
+This project gives an example of ONAP-compliant logging using SLF4J logging.
+
+## Adapter
+
+In ```org.onap.logging.ref.slf4j.common```, there are TWO classes:
+1. ```org.onap.logging.ref.slf4j.common.ONAPLogConstants```, providing declarations of standard ONAP Markers, MDCs and HTTP headers.
+2. ```org.onap.logging.ref.slf4j.common.ONAPLogAdapter```, providing a lightweight, compliant implementation of the ONAP logging spec.
+
+The adapter provides:
+1. A loosely-coupled SLF4j logging wrapper:
+ * To be used for logging ONAP ```entry```, ```exit``` and ```invoke``` behavior.
+ * Devolving all *application* logging to the component, via the regular SLF4J ```Logger``` facade.
+2. Customization options:
+ * *Cheap*, by way of bean properties. This is suited to most Use Cases.
+ * *Sophisticated*:
+ * By OPTIONALLY implementing one of a number of adapters:
+ * ```RequestAdapter``` to read incoming headers.
+ * ```ServiceDescriptor``` for reporting attributes of the current service.
+ * ```ResponseDescriptor``` for reporting outcomes.
+ * ```RequestBuilder``` for setting southbound request headers.
+ * By OPTIONALLY overriding methods like ```ONAPLogAdapter#setMDCs(RequestAdapter)```.
+
+Note that:
+* The adapter implementation uses static inner classes in order to fit in a single source file. This was an objective.
+
+## WAR
+
+Building produces a simple (spring-boot](https://projects.spring.io/spring-boot/) example WAR, which can be launched from this directory with:
+
+```bash
+$ java -war target/*war
+```
+
+The WAR publishes four web services:
+1. ```services/alpha```
+2. ```services/beta```
+3. ```services/gamma```
+4. ```services/delta```
+
+... each of which can invoke the others.
+
+The purpose of this WAR is to demonstrate minimalist ONAP-compliant logging for web components, but a secondary purpose is to demonstrate that the call graph can be generated for a (mostly) representative set of interacting REST services.
+
+## Tests
+
+Tests for:
+1. Code in the (potentially) reusable ``common`` package.
+2. Validating that emitted logs can be used to generate an unambiguous call graph.

+/**
+ * Extensible adapter for cheaply meeting ONAP logging obligations using
+ * an SLF4J facade.
+ *
+ * <p>This can be used with any SLF4J-compatible logging provider, with
+ * appropriate provider configuration.</p>
+ *
+ * <p>The basics are that:
+ * <ul>
+ * <li>{@link #entering} sets all MDCs.</li>
+ * <li>{@link #exiting} unsets all MDCs *and* logs response information.</li>
+ * <li>{@link #invoke} logs and returns a UUID to passed during invocation,
+ * and optionally sets these for you on your downstream request by way of
+ * an adapter.</li>
+ * <li>Call {@link #getServiceDescriptor()} and its setters to set service-related MDCs.</li>
+ * <li>Call {@link #getResponseDescriptor()} and its setters to set response-related MDCs.</li>
+ * </ul>
+ * </p>
+ *
+ * <p>Minimal usage is:
+ * <ol>
+ * <li>#entering(RequestAdapter)</li>
+ * <li>#invoke, #invoke, ...</li>
+ * <li>#getResponse + setters (or #setResponse)</li>
+ * <li>#exiting</li>
+ * </ol>
+ * </p>
+ *
+ * <p> ... if you're happy for service information to be automatically derived as follows:
+ * <ul>
+ * <li><tt>ServiceName</tt> - from <tt>HttpServletRequest#getRequestURI()</tt></li>
+ * <li><tt>InstanceUUID</tt> - classloader-scope UUID.</li>
+ * </ul>
+ * </p>
+ *
+ * <p>... and if those defaults don't suit, then you can override using properties on
+ * {@link #getServiceDescriptor()}, or by injecting your own adapter using
+ * {@link #setServiceDescriptor(ServiceDescriptor)}, or by overriding
+ * a <tt>protected</tt> methods like{@link #setEnteringMDCs}.</p>
+ *
+ * <p>For everything else:
+ * <ul>
+ * <li>The underlying SLF4J {@link Logger} can be retrieved using {@link #unwrap}.
+ * Use this or create your own using the usual SLF4J factor.</li>
+ * <li>Set whatever MDCs you like.</li>
+ * <li>Log whatever else you like.</li>
+ * </ul>
