Feign如何传实体Bean
需要加一个@RequestBody序列化对象
|
1 2 3 4 5 6 7 8 |
/** * 新增 */ @PostMapping ( "saveOrder" ) @ResponseBody public void saveOrder( @RequestBody OrderBean orderBean) { userService.saveOrder(orderBean); } |
接口接收请求也要加一个@RequestBody注解
|
1 2 3 4 5 6 |
/** * 新增 * @param orderBean */ @PostMapping ( "saveOrder" ) public void saveOrder( @RequestBody OrderBean orderBean); |
Feign注入Bean为null,启动报错
主要是feign版本和swagger版本冲突，本项目spring cloud 版本为 Finchley.M8
swagger冲突版本

feign Service案例
|
1 2 3 4 5 |
@FeignClient (name = "service-weixin" ,fallback = OAuthServiceFallBack. class , configuration = FeignConfig. class ) public interface OAuthService { @RequestMapping (value = "/oauth/getOauth2AuthorizationUrl" , method = RequestMethod.GET) ResultBean<String> getOauth2AuthorizationUrl( @RequestParam ( "url" )String url); } |
controller注入
|
1 2 3 4 5 6 7 8 |
@RestController @RequestMapping ( "/ticket" ) public class TicketController { @Autowired private TicketService ticketService; @Autowired private OAuthService oAuthService; ... |
以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
