為什麼要寫這篇貼?
要寫一個最簡單的CRUD 符合 Restful Api 規範的 一個Controller, 想百度搜尋一下 直接複製拷貝 簡單修改一下 方法內程式碼。
然而, 搜尋結果讓我無語到家。 沒一個是正在符合 Restful Api 規範的例項。 最無語的是 你呀直接 JSP 頁面了,還說什麼 Restful Api 啊!!!
為方便以後自己複製拷貝使用,我把自己剛寫的貼出來。
Swagger2:
@Configuration @EnableSwagger2 public class Swagger2 { @Bean public Docket createRestApi() { return new Docket(DocumentationType.SWAGGER_2) .apiInfo(apiInfo()) .select() .apis(RequestHandlerSelectors.basePackage("com.dj.edi.web")) .paths(PathSelectors.any()) .build(); } private ApiInfo apiInfo() { return new ApiInfoBuilder() .title("EID 使用者 CRUD") .description("EID 使用者 CRUD") .version("1.0") .build(); } }
Application:
@SpringBootApplication @Import(springfox.bean.validators.configuration.BeanValidatorPluginsConfiguration.class) public class ComEdiOrderUserApplication { public static void main(String[] args) {SpringApplication.run(ComEdiOrderUserApplication.class, args);} }
UserApiController:
@RestController @RequestMapping("/v1/user") public class UserApiController { private static final Logger LOGGER = LoggerFactory.getLogger(UserApiController.class); @Autowired private ClientUsersRepository repository; @ApiOperation(value = "獲取所有使用者資料") @RequestMapping(value = "/list", method = RequestMethod.GET) public ResponseEntity<List<ClientUsers>> getClientUsersList() { try { return ResponseEntity.ok(repository.findAll()); } catch (Exception e) { LOGGER.info(" 獲取所有使用者資料異常 " + e.getMessage(), e); return ResponseEntity.status(500).body(null); } } @ApiOperation(value = "獲取使用者資料") @ApiImplicitParam(name = "id", value = "使用者ID", required = true, dataType = "String", paramType = "path") @RequestMapping(value = "/{id}", method = RequestMethod.GET) public ResponseEntity<ClientUsers> getClientUsers(@PathVariable String id) { try { return ResponseEntity.ok(repository.findOne(id)); } catch (Exception e) { LOGGER.info(" 獲取使用者資料 " + id + " 資料異常 " + e.getMessage(), e); return ResponseEntity.status(500).body(null); } } @ApiOperation(value = "建立使用者", notes = "根據User物件建立使用者") @ApiImplicitParam(name = "users", value = "使用者詳細實體user", required = true, dataType = "ClientUsers", paramType = "body") @RequestMapping(method = RequestMethod.POST) public ResponseEntity<ClientUsers> createUser(@Valid @RequestBody ClientUsers users) { try { users.setId(ObjectId.get().toString()); return ResponseEntity.ok(repository.save(users)); } catch (Exception e) { LOGGER.info(" 建立使用者 " + users + " 資料異常 " + e.getMessage(), e); return ResponseEntity.status(500).body(null); } } @ApiOperation(value = "更新使用者詳細資訊", notes = "根據url的id來指定更新物件,並根據傳過來的user資訊來更新使用者詳細資訊") @ApiImplicitParams({ @ApiImplicitParam(name = "id", value = "使用者ID", required = true, dataType = "String", paramType = "path"), @ApiImplicitParam(name = "user", value = "使用者詳細實體user", required = true, dataType = "ClientUsers", paramType = "body") }) @RequestMapping(value = "{id}", method = RequestMethod.PUT) public ResponseEntity<ClientUsers> updateUser(@PathVariable("id") String id,@Valid @RequestBody ClientUsers user) { try { user.setId(id); return ResponseEntity.ok(repository.save(user)); } catch (Exception e) { LOGGER.info(" 更新使用者 " + user + " 資料異常 " + e.getMessage(), e); return ResponseEntity.status(500).body(null); } } @ApiOperation(value = "刪除使用者", notes = "根據url的id來指定刪除物件") @ApiImplicitParam(name = "id", value = "使用者ID", required = true, dataType = "String", paramType = "path") @RequestMapping(value = "{id}", method = RequestMethod.DELETE) public ResponseEntity<String> deleteUser(@PathVariable String id) { try { repository.delete(id); return ResponseEntity.ok("ok"); } catch (Exception e) { LOGGER.info(" 刪除使用者 " + id + " 資料異常 " + e.getMessage(), e); return ResponseEntity.status(500).body(null); } } }
ClientUsersRepository:
@Component public interface ClientUsersRepository extends MongoRepository<ClientUsers, String> { ClientUsers findByips(String ip); ClientUsers findByclientFlag(String clientFlag); }
ClientUsers:
@Data public class ClientUsers implements Serializable { @Id private String id; /** * 使用者名稱稱 */ @NotBlank(message = "使用者名稱稱 不能為空") @Pattern(regexp = "^(?!string)",message = "不能是 stirng") private String userName; /** * ip */ @NotNull(message = "ip 至少需要個") private List<String> ips; /** * 標識 */ @NotBlank(message = " 標識 不能為空") @Pattern(regexp = "^(?!string)",message = "不能是 stirng") private String clientFlag; /** * 客戶服務ID */ @NotBlank(message = "客戶服務ID 不能為空") @Pattern(regexp = "^(?!string)",message = "不能是 stirng") private String checkID; }
有哪裡不好的希望指正
