如何解决如何将 Spring Rest 控制器从 Spring HATEOAS 0.x 迁移到 1.x？
我正在尝试在自定义 REST 控制器类中重新创建 Spring Data REST 控制器的功能，以便我可以获得 HAL 格式的 JSON 并能够使用投影。现在我可以使用以下代码在 Spring Boot 1.5.17 中做到这一点。
@RequestMapping(method = GET,value = "students/fetchProfile")
public @ResponseBody
ResponseEntity<?> fetchStduentProfile(@RequestParam(required = true) String idNumber,PersistentEntityResourceAssembler resourceAssembler) {
Student student = studentHandler.fetchStudent(idNumber);
if (student != null) {
return ResponseEntity.ok(resourceAssembler.toResource(student));
} else {
return new ResponseEntity<>(null,HttpStatus.NOT_FOUND);
}
}
但是一旦我升级到 Spring Boot 2.3.8，我就会收到一个 HttpMessageNotWritableException
265.79 kB (204.8 kB loaded)
org.springframework.http.converter.HttpMessageNotWritableException: Could not write JSON: Infinite recursion (StackOverflowError); nested exception is com.fasterxml.jackson.databind.JsonMappingException: Infinite recursion (StackOverflowError) (through reference chain: org.springframework.data.jpa.mapping.JpaPersistentPropertyImpl["owner"]->org.springframework.data.jpa.mapping.JpaPersistentEntityImpl["idProperty"]->org.springframework.data.jpa.mapping.JpaPersistentPropertyImpl["owner"]->org.springframework.data.jpa.mapping.JpaPersistentEntityImpl["idProperty"]-

现在我知道 Spring HATEOAS 发生了重大变化，但我不确定如何将此控制器迁移到新的 HATEOS 类。我什至尝试过 resourceAssembler.toModel() 并且它产生了同样的异常。
那么如何让这个控制器与新版本的 Spring HATEOAS 一起工作，以便我可以获得 HAL 格式的 JSON 并使用投影参数？
