问题描述
我使用其相应的实体存储库编写了一个自定义的 RepositoryRestController
。在此url上执行请求时,查询正在我的控制台中运行,但是url返回404。我还能够在日志中看到此url的requestHandlerMapping。请参阅我的以下代码段。
I have written a custom RepositoryRestController
using its corresponding entity repository. When performing request on this url, the query is running in my console, but the url returns 404. I also able to see the requestHandlerMapping for this url in logs. Refer my following code snippet.
存储库:
@RepositoryRestResource
public interface FooRepository extends BaseRepository<Foo, Integer> {
@RestResource(exported = false)
List<Foo> findByName(String name);
}
控制器:
@RepositoryRestController
public class FooResource {
@Aurowired
FooRepository fooRepository;
@Autowired
RestApiService restApiService;
@RequestMapping(value = "/foos/search/byApiName", method = GET)
public ResponseEntity<?> findByApiName(String name) {
List<String> apiNames = restApiService.getNameLike(name);
List<Foo> fooList = fooRepository.findByName(name);
List<String> fooNames = // list of names from fooList
...
System.out.println("FETCHING apiNames");
return apiNames;
}
当我执行以下curl命令时
When I execute the following curl command
curl -X GET http:localhost:8080/foos/search/byApiName
响应返回404错误。我不知道为什么
the response returns 404 error. I don't know why. But he printout statement is printing in console.
@hat我在这里做错了吗?
@hat I am doing wrong here?
推荐答案
我建议您将 @ResponseBody
添加到您的方法或返回值中(如SDR示例),或将您的列表包装在ResponseEntity中。
I would suggest that you need to add the @ResponseBody
to either your method or to the return value (as in the SDR example http://docs.spring.io/spring-data/rest/docs/current/reference/html/#customizing-sdr.overriding-sdr-response-handlers) or wrap your list in an ResponseEntity.
不确定这些方法之间是否有任何区别,但都应该如Spring MVC文档中所述:
Not sure if there are any differences between these approaches but all should, as noted in the Spring MVC docs:
表示返回类型应直接写入HTTP
响应正文中(而不是放置在Model中,或[be]解释为视图
名称)。
鉴于您调试了语句打印,但是得到了404,看来后面的动作是会发生什么。 / p>
Given you debug statement prints but you get a 404 it would seem the latter action is what happens.
@RequestMapping(value = "/foos/search/byApiName", method = GET)
@ResponseBody
public ResponseEntity<?> findByApiName(String name) {
// ....
}
或
@RequestMapping(value = "/foos/search/byApiName", method = GET)
public @ResponseBody ResponseEntity<?> findByApiName(String name) {
//....
}
或者,
@RequestMapping(value = "/foos/search/byApiName", method = GET)
public ResponseEntity<List<String>> findByApiName(String name) {
//....
return new ResponseEntity<List<String>>(fooNames, HttpStatus.OK);
}
