インタフェース StructuredParameterProvider

public interface StructuredParameterProvider

A user-supplied provider for StructuredParameters.

Any CDI beans registered under this class are applied to each log entry that is logged.

Example:

 @Singleton
 @Unremovable
 public final class TraceLogParameterProvider implements StructuredParameterProvider {

   @Override
   public StructuredParameter getParameter() {
     var b = Json.createObjectBuilder();
     b.add("traceId", Span.current().getSpanContext().getTraceId());
     b.add("spanId", Span.current().getSpanContext().getSpanId());
     return () -> b;
   }
 }
 

Result:

 {
   "jsonPayload": {
     "message": "Request rejected: unauthorized.",
     "traceId": "39f9a49a9567a8bd7087b708f8932550",
     "spanId": "c7431b14630b633d"
   }
 }

メソッドの詳細

getParameter

StructuredParameter getParameter()

Provides a StructuredParameter to add to each log entry that is logged.

It is often useful to return a custom StructuredParameter rather than a KeyValueParameter from this method. This way multiple key–value pairs can be generated by a single invocation.
