How to send request parameters with the new Spring Boot 3.2 RestClient?

I have looked at the examples and the javadoc but I can't find an example anywhere.

I am migrating from WebClient to the new RestClient.

I have looked online in the obvious places.

I am trying to send 5 parameters and a path variable.

Solution

  • Example of using RestClient:

    RestClient restClient = RestClient.builder()
      .baseUrl("https://test.com/api")
      .build();

String pathVariable = "pathVariable";
ResponseEntity<String> response = restClient.get()
    .uri(uriBuilder -> uriBuilder
         .path("/" + pathVariable)
         .queryParam("param1", "value1")
         .queryParam("param2", "value2")
         .queryParam("param3", "value3")
         .queryParam("param4", "value4")
         .queryParam("param5", "value5")
         .build())
    .header("Content-Type", "application/json")
    .retrieve()
    .toEntity(String.class)
    .block();
