spring boot 1.3.3 create multiple resttemplate per env - spring-boot

Question

I am on spring boot 1.3.3 version, I have a requirement where my spring boot application need to call endpoint(s) based on env passed,
which means if env passed as Dev i would need to call devendpoint,
if env passed as Dev1 then need to call dev1endpoint and so on.
So how can I do this ?
Do I need to create multiple restTemplate instances ?
Should I construct the resttemplate dynamically based on env passed ?
As part of constructing resttemplate i would also need to add appllicable interceptor based on env selected.
Plesae suggest.

Answer 1

You can have two beans of the same class. One can be labeled as the primary, and the use on the #Autowired can specify which one to use with the #Qualifier.
Example:
#Configuration
public class MyConfig {
#Bean
#Primary
public RestTemplate typicalConfig() {
// various configs on your rest template
return new RestTemplate();
}
#Bean
public RestTemplate lessTypical() {
// various alternate configurations
return new RestTemplate();
}
}
Now in your service class:
#Service
public class MyService {
#Autowired
RestTemplate typicalRestTemplate;
#Autowired
#Qualifier("lessTypical")
private RestTemplate alternateRestTemplate;
...
}

correct me if I didn't understand your question. I understand that you are going to have different environments but you are going to change this endpoints in runtime depends on some information or whatever, but I don't understand the part when you said you have to create multiple instances of restTemplate for that environments, from my experience on spring boot applications you don't have to do things like that, You just have to create your restTemplate configuration bean.
#Bean
public RestTemplate restTemplate() {
return new RestTemplate();
}
And then injected that object on your services class and do whatever you want with them. I recommend you to read the follow article about restTempalte may this could help you http://www.baeldung.com/rest-template
