Trace http requests with Spring Actuator

List the last http request with ease

Spring Actuator provides also a httptrace endpoint. You get the last HTTP request with /httptrace.

After adding Spring Boot Actuator dependencies to your project dependencies, you have to expose the httptrace endpoint via your application.properties:

[code]management.endpoints.web.exposure.include=httptrace[/code]

[code] curl http://127.0.0.1:8080/actuator/httptrace | jq { "traces": [{ "timestamp": "2019-01-05T07:45:14.406Z", "principal": null, "session": null, "request": { "method": "GET", "uri": "http://127.0.0.1:8080/helloworld/peter", "headers": { "host": ["127.0.0.1:8080"], "accept": ["*/*"], "user-agent": ["curl/7.58.0"] }, "remoteAddress": null }, "response": { "status": 200, "headers": { "Content-Length": ["16"], "Date": ["Sat, 05 Jan 2019 07:45:14 GMT"], "Content-Type": ["text/plain;charset=UTF-8"] } }, "timeTaken": 7 }] } [/code]

In Spring Boot 2.0 the trace endpoint was renamed to httptrace. You can even configure the trace details (see TraceProperties.java code).
Here is an example

[code]management.httptrace.include = parameter[/code]


Here is the source code of my sample application 🙂
