                      QUESTION

                      How does Spring (Boot) work with Pageable in controllers method argument?

                      Asked 2021-Oct-03 at 17:57

                      I'm curious to know how does Spring Boot work with Pageable in controllers methods? I add a Pageable parameter to my controller method and Spring handle it for me.

                      There is an example:

                      @GetMapping("search")
                      public ResponseEntity<List<ProductDTO>> searchProducts(
                              @RequestParam(value = "query", required = false, defaultValue = "") String query,
                              Pageable pageable) {
                          Specification<Product> spec = Specification.where(null); 
                          if(!StringUtils.isBlank(query)) {
                              Node rootNode = new RSQLParser().parse(query);
                              spec = rootNode.accept(new CustomRsqlVisitor<Product>());
                          }
                          Page<ProductDTO> page = service.searchProducts(spec, pageable);
                          // My Additional code....
                      }
                      

                      Now let's back to the main question: How does Spring handle Pageable? Then, how can I create the same business for myself to handle Specifications on input methods?

                      P.S. 1: I used rsql-parser to implement search over my products.

                      P.S. 2: You can find custom classes that are used to generate Specification under rsql package
