feignClient传参（参数为对象类型）的一个坑

客户端

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

服务端

1   @RequestMapping(value = "/comment")
2   public R comment(@RequestBody FriendCircleComment friendCircleComment){
3     friendCircleCommentService.comment(friendCircleComment);
4     return new R();
5   }

这么传参是没问题的，服务端也能接收到

但是，问题来了，

小程序的post请求的header必须为

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

导致后台为@RequestBody接收不到参数，

定义@RequestBody接收参数的headers类型必须为 header：{ 'content-type':'application/json'  }, 

所以这样就有冲突，feignClient和定义为'content-type':'application/x-www-form-urlencoded'的请求接口不能共用

解决方法

不使用对象接收，使用基本类型接收

如下

客户端

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

服务端

 1   @RequestMapping(value = "/comment")
 2   public R comment(@RequestParam(value = "friendCircleId",required = false)Integer friendCircleId,
 3                    @RequestParam(value = "memberId",required = false)Integer memberId,
 4                    @RequestParam(value = "parentId",required = false)Integer parentId,
 5                    @RequestParam(value = "comment",required = false)String comment,
 6                    @RequestParam(value = "replyMemberId",required = false)Integer replyMemberId
 7                    ){
 8     FriendCircleComment friendCircleComment = new FriendCircleComment();
 9     friendCircleComment.setFriendCircleId(friendCircleId);
10     friendCircleComment.setMemberId(memberId);
11     friendCircleComment.setParentId(parentId);
12     friendCircleComment.setComment(comment);
13     friendCircleComment.setReplyMemberId(replyMemberId);
14     friendCircleCommentService.comment(friendCircleComment);
15     return new R();
16   }
