I’m working on a microservices project using Spring Boot and have multiple services that need to communicate with each other. Currently, I have the following services:
- Employee Service
- Department Service
- Project Service.
In the Employee Service, I need to call endpoints from both the Department Service and the Project Service using WebClient. Initially, I created individual WebClient beans for each service, like this:
@Autowired
private LoadBalancedExchangeFilterFunction filterFunction;
@Bean
public WebClient departmentWebClient() {
return WebClient.builder()
.baseUrl("https://department-service")
.filter(filterFunction)
.build();
}
@Bean
public DepartmentClient departmentClient() {
HttpServiceProxyFactory httpServiceProxyFactory
= HttpServiceProxyFactory
.builder(WebClientAdapter.forClient(departmentWebClient()))
.build();
return httpServiceProxyFactory.createClient(DepartmentClient.class);
}
@Bean
public WebClient projectWebClient() {
return WebClient.builder()
.baseUrl("https://project-service")
.filter(filterFunction)
.build();
}
@Bean
public TaskClient taskClient() {
HttpServiceProxyFactory httpServiceProxyFactory
= HttpServiceProxyFactory
.builder(WebClientAdapter.forClient(projectWebClient()))
.build();
return httpServiceProxyFactory.createClient(TaskClient.class);
}
While this works, it seems inefficient and cumbersome as the number of services increases. I’m looking for a better and more flexible approach if possible.
Could someone guide me on the best approach to achieve this, possibly with code examples?
If possible i curious and looking for another way to manage multiple WebClient configurations in a Spring Boot microservices architecture. The solution should minimize boilerplate code and handle dynamic client creation gracefully.
