[SOLVED] get external url from application.properties with pathvariable

get external url from application.properties with pathvariable

I have a situation were i need to call an external endpoint. I am using spring boot. I have placed the endpoint in the application.properties file and used a placeholder for the parameter I need to change like so: messageapi=http://localhost:8080/uxt/get/{{userId}}/messages/notification

where userid is a dynamic value generated in code.

what is the most efficient way for me to to access this value in asyncRestTemplate.exchange() method and replace the variable?

Solution

This how i would approach it. I would plase a string placeholder, get it with @Value and then I would use String.format. So here it goes:

Step 1 use this format in your application.properties file entry messageapi=http://localhost:8080/uxt/get/%s/messages/notification

Step 2 in your class use the

@Value("${messageapi}")
String messageapi;

and store the value

Step 3 use the following to replace the userId String.format(messageapi,"userId ")); and in your case somthing like
```
asycTemp.exchange(String.format(messageapi,"userId ")), method, requestEntity, responseType);
```

I hope I helped
