Rest FaignClient正在更改传递给它的LocalDate的格式

我的应用程序中有一个

@FeignClient

：

@FeignClient(name="${mongo.service.id}", url="${mongo.service.url}")
public interface MongoCustomerClaimInterface {
    @GetMapping(path = "/api/customerClaim/countClaims/{businessDate}")
    List<TransactionClaimStatusData> countClaimsByStatusToBusinessDate(
    @PathVariable @DateTimeFormat(iso = DateTimeFormat.ISO.DATE) 
    LocalDate businessDate);
}

调用将生成

404

错误和日志：

2020-24-02 18:10:25.433 INFO  DashboardServiceImpl - formattedDate: 2020-02-23
2020-24-02 18:10:25.440 DEBUG
RequestMappingHandlerMapping:
Looking up handler method for path /api/customerClaim/countClaims/2/23/20
RequestMappingHandlerMapping:
Did not find handler method for [/api/customerClaim/countClaims/2/23/20]

虽然我以

yyyy-mm-dd

格式传递日期，但它将匹配：

• @DateTimeFormat（iso=DateTimeFormat.iso.DATE）

• 佯装以某种方式更改日期，然后找不到匹配的url

---

我怎样才能防止Faign这样做，并配置一个统一的格式化程序呢？

显然，Faign不能处理所有的SpringMvc注释

@DateTimeFormat

是一个SpringMvc注释，而不是一个伪装的客户端注释。 我通过做几件事来解决这个问题：

在我的MvcConfig类中创建了一个MessageConvertersConfiguration类。 在其中，我创建了一个LocalDate&LocalDateTime转换器bean，并将其添加到该配置程序在http消息到达时使用的转换器列表中：

最后，我将配置属性添加到我的佯装客户端：

@FeignClient（name=“${mongo.service.id}”，url=“${mongo.service.url}”，configuration=FeignConfig.class）
公共接口MongoCustomerClaimInterface{
@GetMapping（路径=“/api/customerClaim/countClaimsByStatusToBusinessDate/{businessDate}”）
列出countClaimsByStatusToBusinessDate（@PathVariable@DateTimeFormat（iso=DateTimeFormat.iso.DATE）LocalDate businessDate）；
}

如何定义newMappingJackson2HttpMessageConverter？
