解决：

@FeignClient(url = "${kx.service.url}",name="kxserviceurl")public interface KxServiceApi {    @RequestMapping(value = "/t1", method = RequestMethod.GET)    public String t1(@RequestParam(value = "id",required = false)Integer id);    @RequestMapping(value = "/t3", method = RequestMethod.POST)    public String t3(@RequestBody UserVo userVo);    @RequestMapping(value = "/t4", method = RequestMethod.POST,consumes = MediaType.APPLICATION_JSON_VALUE)    public String t4(String s);}

一般有以下几种原因：

1、可能返回类型不对，注意保持一致！

2、可能是POST的头文件不一致！

consumes = MediaType.APPLICATION_JSON_VALUE

加这个类型就可以了
