我创建了一个带有spring Boot 依赖项的Gradle项目,这是一个rest api。我默认使用netbeans版本12.6和java 17。应用程序运行在端口号8080的tomcat服务器上。我想在调用rest api方法时将数据显示到localhost中,但主要问题是当我尝试调用www.example.com的方法instance.http://localhost:8080/result/2。它显示以下错误消息。
{“错误”:“未找到-001”,“消息”:“未找到2”}
这是杰森的档案。

下面是主类代码。
@SpringBootApplication
public class ElectionsApiApplication {
public static void main(String[] args) throws IOException {
SpringApplication.run(ElectionsApiApplication.class, args);
}
}
这里是存储库。
@Component
public class MapBasedRepository implements ResultService {
private final Map<Integer,ConstituencyResult> results;
public MapBasedRepository() {
results = new ConcurrentHashMap<>();
}
@Override
public ConstituencyResult GetResult(Integer id) {
return results.get(id);
}
@Override
public void NewResult(ConstituencyResult result) {
results.put(result.getId(), result);
}
@Override
public Map<Integer, ConstituencyResult> GetAll() {
return results;
}
@Override
public void reset() {
results.clear();
}
@Override
public Scoreboard soreboardResult(Scoreboard scoreboard) {
return scoreboard;
}
}
下面是控制器代码。
@RestController
public class ResultsController {
private final ResultService results;
public ResultsController(ResultService resultService) {
this.results = resultService;
}
@GetMapping("/result/{id}")
ConstituencyResult getResult(@PathVariable Integer id) {
ConstituencyResult result = results.GetResult(id);
if (result == null) {
throw new ResultNotFoundException(id);
}
return results.GetResult(id);
}
@PostMapping("/result")
ResponseEntity<String> newResult(@RequestBody ConstituencyResult result) {
if (result.getId() != null) {
results.NewResult(result);
return ResponseEntity.created(URI.create("/result/"+result.getId())).build();
}
return ResponseEntity.badRequest().body("Id was null");
}
@GetMapping("/scoreoard")
Scoreboard soreboardResult(Scoreboard scoreboard) {
if(scoreboard==null){
throw new ResultNotFoundException();
}
return new Scoreboard();
}
}
下面是异常处理程序类。
@RestControllerAdvice
public class ResultsExceptionHandler {
@ExceptionHandler(ResultNotFoundException.class)
public ResponseEntity<ApiResponse> handleNotFoundApiException(
ResultNotFoundException ex) {
ApiResponse response =
ApiResponse.builder()
.error("not-found-001")
.message(String.format("%d not found",ex.getId()))
.build();
return new ResponseEntity<>(response, HttpStatus.NOT_FOUND);
}
@ExceptionHandler(NotImplementedException.class)
public ResponseEntity<ApiResponse> handleNotImplementedApiException(
NotImplementedException ex) {
ApiResponse response =
ApiResponse.builder()
.error("not-implemented-002")
.message("Function not yet implemented")
.build();
return new ResponseEntity<>(response, HttpStatus.INTERNAL_SERVER_ERROR);
}
}
下面是测试代码。
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
class ElectionsApiApplicationIntegrationTests {
@LocalServerPort
private int port;
private URL base;
@Autowired
private ObjectMapper objectMapper;

@BeforeEach
public void setUp() throws Exception {

@AfterEach
public void reset() throws Exception {

}
@Test
public void first5Test() throws Exception {

assertNotNull(scoreboard);
//Scoreboard sc = objectMapper.readValue(new File(".\\result001.json"), Scoreboard.class);

private Scoreboard runTest(int numberOfResults) throws Exception {

Class<?> clazz = this.getClass();
InputStream is = clazz.getResourceAsStream(String.format("/sample-election-results/result%s.json",String.format("%03d",i)));

}
ResponseEntity<Scoreboard> scores = template.getForEntity(base.toString()+"/scoreboard", Scoreboard.class);
return scores.getBody();
}
}

请求路径为http://localhost:8080/result/2,这是在查询id = 2,而您的json文件中不存在该id = 2。此文件仅包含id = 16
