feignClient傳參（參數為對象類型）的一個坑

客戶端

    @RequestMapping(value = "/friendCircleComment/comment",method = RequestMethod.POST)
    R comment(@RequestBody FriendCircleComment friendCircleComment);

服務端

  @RequestMapping(value = "/comment")
  public R comment(@RequestBody FriendCircleComment friendCircleComment){
    friendCircleCommentService.comment(friendCircleComment);
    return new R();
  }

這么傳參是沒問題的，服務端也能接收到

但是，問題來了，

小程序的post請求的header必須為

  header：{ 'content-type':'application/x-www-form-urlencoded'  }, 

導致后台為@RequestBody接收不到參數，

feignClient默認參數請求類型是

header：{ 'content-type':'application/json'  }, 

定義@RequestBody接收參數的headers類型必須為 header：{ 'content-type':'application/json'  }, 

所以這樣就有沖突，feignClient和定義為'content-type':'application/x-www-form-urlencoded'的請求接口不能共用

解決方法

不使用對象接收，使用基本類型接收

如下

客戶端

    @RequestMapping(value = "/friendCircleComment/comment",method = RequestMethod.POST)
    R comment(@RequestParam(value = "friendCircleId",required = false)Integer friendCircleId,
              @RequestParam(value = "memberId",required = false)Integer memberId,
              @RequestParam(value = "parentId",required = false)Integer parentId,
              @RequestParam(value = "comment",required = false)String comment,
              @RequestParam(value = "replyMemberId",required = false)Integer replyMemberId);

服務端

  @RequestMapping(value = "/comment")
  public R comment(@RequestParam(value = "friendCircleId",required = false)Integer friendCircleId,
                   @RequestParam(value = "memberId",required = false)Integer memberId,
                   @RequestParam(value = "parentId",required = false)Integer parentId,
                   @RequestParam(value = "comment",required = false)String comment,
                   @RequestParam(value = "replyMemberId",required = false)Integer replyMemberId
                   ){
    FriendCircleComment friendCircleComment = new FriendCircleComment();
    friendCircleComment.setFriendCircleId(friendCircleId);
    friendCircleComment.setMemberId(memberId);
    friendCircleComment.setParentId(parentId);
    friendCircleComment.setComment(comment);
    friendCircleComment.setReplyMemberId(replyMemberId);
    friendCircleCommentService.comment(friendCircleComment);
    return new R();
  }
