我一直坚持为我的一个微服务建立一个feignclient。我使用标准（用于过滤）和分页。在我的一个微服务上，我有一个服务休息区，另一个则使用feignclient请求。
AccountCriteria（来自jhipster的条件接口）
public class AccountCriteria implements Serializable, Criteria {
private LongFilter id;
private StringFilter user;
private LongFilter bankWebId;
private LongFilter bankApiId;
private LongFilter deactivationReasonId;
public AccountCriteria() {
}
public AccountCriteria(AccountCriteria other) {
this.id = other.id == null ? null : other.id.copy();
this.user = other.user == null ? null : other.user.copy();
this.bankWebId = other.bankWebId == null ? null : other.bankWebId.copy();
this.bankApiId = other.bankApiId == null ? null : other.bankApiId.copy();
this.deactivationReasonId = other.deactivationReasonId == null ? null : other.deactivationReasonId.copy();
}
@Override
public Criteria copy() {
return new AccountCriteria(this);
}
}
AccountIdentifierResource（其余资源）
@RestController
@RequestMapping(value = "/api", produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
public class AccountIdentifierResource {
log.debug("REST request to get AccountIdentifiers by criteria: {}", criteria);
Page<AccountIdentifier> page = accountIdentifierQueryService.findByCriteria(criteria, pageable);
HttpHeaders headers = PaginationUtil.generatePaginationHttpHeaders(uriBuilder.queryParams(queryParams), page);
return ResponseEntity.ok().headers(headers).body(page.getContent());
}
IdentityProviderFeignClient（虚假客户端）
@AuthorizedFeignClient(name = "identityprovider")
public interface IdentityProviderFeignClient {
@GetMapping("/api/account-identifiers")
List<AccountIdentifier> getAllAccountIdentifiers(AccountCriteria criteria,
Pageable pageable, @RequestParam("queryParams") MultiValueMap<String, String> queryParams, UriComponentsBuilder uriBuilder);
}
**IdentityProviderService** (the service interface)
```java
public interface IdentityProviderService {
List<AccountIdentifier> getAllAccountIdentifiers(AccountCriteria criteria, Pageable pageable, MultiValueMap<String, String> queryParams, UriComponentsBuilder uriBuilder);
}
IdentityProviderServiceImpl（服务实现）
@Service
public class IdentityProviderServiceImpl implements IdentityProviderService {
private final Logger log =
LoggerFactory.getLogger(IdentityProviderServiceImpl.class);
private final IdentityProviderFeignClient identityProviderFeignClient;
public IdentityProviderServiceImpl(IdentityProviderFeignClient identityProviderFeignClient) {
this.identityProviderFeignClient = identityProviderFeignClient;
}
@Override
public List<AccountIdentifier> getAllAccountIdentifiers(AccountCriteria criteria, Pageable pageable, MultiValueMap<String, String> queryParams, UriComponentsBuilder uriBuilder) {
log.debug("Request to get all AccountIdentifier from IdentityProvider with criteria : {}", criteria);
return this.identityProviderFeignClient.getAllAccountIdentifiers(criteria, pageable, queryParams, uriBuilder);
}
}

感谢大家的帮助。
您是否有任何实体可以配置feignclient？
有时我们需要设置解码器/编码器的配置以发送特定的对象。
