Java InvalidMimeTypeException:无效的mime类型“；{Content Type}"；：不包含'/'；

以下是我的服务代码：

public ChangeEmailOutputDto changeEmail( ChangeEmailInputDto changeEmailInputDto) 
{
 return changeEmailClient.changeEmail(changeEmailInputDto.getEmail(), changeEmailInputDto.getMemberId(), MediaType.APPLICATION_JSON_UTF8_VALUE, UUID.randomUUID(), "1");

}

和我的客户代码：

@FeignClient(name = "ChangeEmail",url = "${app.rest.changeEmail}")
public interface ChangeEmailClient 
{
    @PostMapping(value = "/{memberId}")
    ChangeEmailResponseDto changeEmail(@RequestBody String username,
                                       @PathVariable("memberId") String memberId,
                                       @RequestHeader(value = "Content-Type") String contentType,
                                       @RequestHeader(value = "x-correlation-id") UUID correlationId,
                                       @RequestHeader(value = "tenant-id") String tenantId);

}

如何在FaignClient中设置

内容类型

？

在注释中添加消费和生产将完成这项工作

@FeignClient(name = "ChangeEmail",url = "${app.rest.changeEmail}")
public interface ChangeEmailClient {
        @PostMapping(value = "/{memberId}", consumes = "application/json", produces = "application/json")
        ChangeEmailResponseDto changeEmail(@RequestBody String username, @PathVariable("memberId") String memberId, @RequestHeader(value = "Content-Type") String contentType, @RequestHeader(value = "x-correlation-id") UUID correlationId, @RequestHeader(value = "tenant-id") String tenantId);
}

}

内容类型的HTTP头字段是

Accept

，而不是

content-type

。请尝试在客户端代码中更改此选项：

@FeignClient(name = "ChangeEmail",url = "${app.rest.changeEmail}")
public interface ChangeEmailClient 
{
    @PostMapping(value = "/{memberId}")
    ChangeEmailResponseDto changeEmail(@RequestBody String username,
                                       @PathVariable("memberId") String memberId,
                                       @RequestHeader(value = "Content-Type") String contentType,
                                       @RequestHeader(value = "x-correlation-id") UUID correlationId,
                                       @RequestHeader(value = "tenant-id") String tenantId);

}

@FeignClient（name=“changemail”，url=“${app.rest.changemail}”）
公共接口客户端
{
@PostMapping（value=“/{memberId}”）
ChangeEmailResponsedToChangeEmail（@RequestBody字符串用户名，
@PathVariable（“memberId”）字符串memberId，
@RequestHeader（value=“Accept”）字符串内容类型，
@RequestHeader（value=“x-correlation-id”）UUID correlationId，
@RequestHeader（value=“tenant id”）字符串tenantId）；
}

内容类型的HTTP头字段是

接受

，而不是

内容类型

。请尝试在客户端代码中更改此选项：

@FeignClient(name = "ChangeEmail",url = "${app.rest.changeEmail}")
public interface ChangeEmailClient 
{
    @PostMapping(value = "/{memberId}")
    ChangeEmailResponseDto changeEmail(@RequestBody String username,
                                       @PathVariable("memberId") String memberId,
                                       @RequestHeader(value = "Content-Type") String contentType,
                                       @RequestHeader(value = "x-correlation-id") UUID correlationId,
                                       @RequestHeader(value = "tenant-id") String tenantId);

}

@FeignClient（name=“changemail”，url=“${app.rest.changemail}”）
公共接口客户端
{
@PostMapping（value=“/{memberId}”）
ChangeEmailResponsedToChangeEmail（@RequestBody字符串用户名，
@PathVariable（“memberId”）字符串memberId，
@RequestHeader（value=“Accept”）字符串内容类型，
@RequestHeader（value=“x-correlation-id”）UUID correlationId，
@RequestHeader（value=“tenant id”）字符串tenantId）；
}

used@Headers（{“Content-Type:application/json”}）和it错误消失了，有人能解释为什么吗？？？used@Headers（{“Content-Type:application/json”}）和it错误消失了，有人能解释为什么吗？？？
