Error: connect ECONNREFUSED 127.0.0.1:8080 in Postman

Testing a basic project in postman but getting

"Error: connect ECONNREFUSED 127.0.0.1:8080".

I am uploading an image in multipart file through postman in form-data along with JSON objects.

Below is my application.properties code.

spring.application.name=products-desc

# DataSource Configuration
spring.datasource.url=jdbc:mysql://localhost:3306/product
spring.datasource.username=root
spring.datasource.password=root


# JPA / Hibernate Configuration
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true


# File Upload Configuration
# Adjust the following properties according to your file upload requirements
# Maximum allowed size of a single file in bytes
spring.servlet.multipart.max-file-size=10MB
# Maximum allowed size of the entire multipart request in bytes
spring.servlet.multipart.max-request-size=10MB
# Temporary directory used to store uploaded files
spring.servlet.multipart.location=uploads

server.port=8080

Below is the run from Intellij

I thought error might be in localhost server,

  1. tried reinstalling postman,
  2. tried using postman web,
  3. turned off defender firewall,
  4. no VPN or proxy servers. Can't find solution for this also
  5. tried changing port numbers but no use.
  6. Rechecked the controller endpoints, URI.

The first error was indeed related to your application not running.

The second error is related to you not calling the proper URL or not calling it in the way that your URL expects. Therefore, api/product is somehow not reachable when you call it.

To further debug this, it would be helpful if you could share your controller code and the method you use to call it (perhaps you are using GET rather than POST, or vice versa), along with some other pieces of code (security, config, etc)

P.S.: Another thing you can do is to create a very simple endpoint in the same controller class, let's say an alive endpoint which just returns a simple JSON or string and shows that the application is running (or you can enable the actuator for that matter). In that case, you can validate that at least your Spring Security and other configurations, and your controller bean are alive, and you are only calling your other endpoint in the wrong way.
