If you are using the Spring Boot application and want to encrypt your credentials, such as DB passwords, server information, or personal data then the simplest way is to use Jasypt. What is Jasypt? Jasypt (Java Simplified Encryption) is a Java…

Developers use Actuator to enable API Gateway routes in order to keep track of the routes being used in their application. By exposing these routes through Actuator endpoints, developers can get valuable information…
Read More Viewing Spring Cloud API Gateway Routes with Spring Boot ActuatorIn a microservices architecture, it is common to have multiple services communicating with each other over the network. This distributed nature of the architecture can make it challenging to diagnose and debug issues when they arise. To address this problem, developers often use monitoring(Micrometer) and tracing tools(Zipkin) to track the flow of requests between microservices.…

In fact, /httptrace has been renamed to /httpexchanges, so this tutorial will teach you how to enable the Actuator’s /httpexchanges API endpoint instead of /httptrace. The httpexchanges endpoint provides information about HTTP request-response exchanges. These HTTP exchanges are essentially…
