我希望用自己的控制器覆盖spring-data-rest中资源的PATCH方法。我目前有以下代码:
我在这里创建了一个示例项目(带有演示错误的测试):https://github.com/JanRenkin/springdatarest。
@RepositoryRestResource
interface ItemRepository extends JpaRepository<Item, Long> {
}
@RepositoryRestController
@Slf4j
class ItemController {
@Autowired
private ItemRepository itemRepository;
@PatchMapping("/items/{id}")
public void updateItem(@PathVariable("id") Long id, @RequestBody ItemDTO itemDTO) {
log.info("Updating item {}", id);
Item found = itemRepository.findOne(id);
found.name = itemDTO.name;
itemRepository.save(found);
}
}
@Data
@NoArgsConstructor
@AllArgsConstructor
class ItemDTO {
String name;
}
我可以通过调用以下命令来创建一个项目:
curl -X POST \
http://localhost:8080/items \
-H 'Content-Type: application/json' \
-d '{
"name" : "anItem"
}'
但是,如果我尝试使用 PATCH
更新项目,如下所示:
curl -X PATCH \
http://localhost:8080/items/1 \
-H 'Content-Type: application/json' \
-d '{
"name" : "update"
}'
请求将由我的控制器处理,但应用程序也会抛出此堆栈跟踪并响应状态码400。
