【问题描述】：

当我使用 Feign Client 发布 Map<String,Object> 时，我收到错误消息：

feign.FeignException: 读取 MAp 的状态 400。

代码

//Client side
@Component
@FeignClient(name = ServiceID.TACHE)
@RibbonClient(name = ServiceID.TACHE)
public interface ITacheService extends ITache {
@RequestMapping(value = TACHE_CONTROLLER + "/save", produces = {"application/json; charset=UTF-8"},method = RequestMethod.POST)
    @ResponseBody
    Map<String, Object> save(@RequestBody Map<String,Object> map);
}

@Controller
@RequestMapping("/task")
public class TaskController {

// Server side
    @RequestMapping(value = "/save", produces = {"application/json; charset=UTF-8"},method = RequestMethod.POST)
    @ResponseBody
    Map<String, Object> save(@RequestBody Map<String, Object> map) throws ParseException { }
}

【解决方案1】：

您真的需要它作为地图吗？

尝试使用 Hashset 或 HashMap 之类的

//Client side
@Component
@FeignClient(name = ServiceID.TACHE)
@RibbonClient(name = ServiceID.TACHE)
public interface ITacheService extends ITache {
@RequestMapping(value = TACHE_CONTROLLER + "/save", produces = {"application/json; charset=UTF-8"},method = RequestMethod.POST)
    @ResponseBody
    HashMap<String, Object> save(@RequestBody HashMap<String,Object> map);
}

@Controller
@RequestMapping("/task")
public class TaskController {

// Server side
    @RequestMapping(value = "/save", produces = {"application/json; charset=UTF-8"},method = RequestMethod.POST)
    @ResponseBody
    HashMap<String, Object> save(@RequestBody HashMap<String, Object> map) throws ParseException { }
}

或

//Client side
@Component
@FeignClient(name = ServiceID.TACHE)
@RibbonClient(name = ServiceID.TACHE)
public interface ITacheService extends ITache {
@RequestMapping(value = TACHE_CONTROLLER + "/save", produces = {"application/json; charset=UTF-8"},method = RequestMethod.POST)
    @ResponseBody
    HashSet<String, Object> save(@RequestBody HashSet<String,Object> set);
}

@Controller
@RequestMapping("/task")
public class TaskController {

// Server side
    @RequestMapping(value = "/save", produces = {"application/json; charset=UTF-8"},method = RequestMethod.POST)
    @ResponseBody
    HashSet<String, Object> save(@RequestBody HashSet<String, Object> set) throws ParseException { }
}

Ewerton，你是说第二个 sn-p 中的 HashSet 吗？
