spring - 将实体链接作为@RequestParam 传递给@RepositoryRestController 方法

Question

我里面有一个 @RepositoryRestController

@RequestMapping(value = "/products/salesReport", method = RequestMethod.GET, produces = "application/json")
    public @ResponseBody
    ResponseEntity<?> get(
            @RequestParam(value = "customer", required = false) Resource<Organization> customer,
            @RequestParam(value = "supplier", required = false) Organization supplier,
            @DateTimeFormat(pattern = "dd-MM-yyyyy") @RequestParam(value = "startDate", required = false) Date startDate,
            @DateTimeFormat(pattern = "dd-MM-yyyyy") @RequestParam(value = "endDate", required = false) Date endDate,
            Pageable pageable
    ) { ...

这里的组织类型请求参数，我想作为 SDR 样式的 uris 传入。当我传入 Long ids 时，它工作正常并自动转换为实体对象。但是当我传入 uri 时，我得到:

Failed to convert value of type [java.lang.String] to required type [org.springframework.hateoas.Resource]; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [org.springframework.hateoas.Resource]: no matching editors or conversion strategy found"

有谁知道 Spring 是否真的支持在 @RepositoryRestController 中自动将 uri 转换为实体对象如何？

试试这个方法:

@RepositoryRestController
@RequestMapping("/products")
public class ProductsController {

    @Autoware
    private ProductService productService;

    @GetMapping("/{id}/report/{data}")
    public ResponseEntity<?> getReport(@PathVariable("id") Product product, @PathVariable("date") Date date) {
        // some checks...
        return ResponseEntity.ok(productService.makeReport(product, date);
    }
}
