Put请求 修改 的写法：

@PutMapping("{id}")
public R updateById(
                     @ApiParam(name = "id", value = "讲师ID", required = true)
                     @PathVariable String id,
                     @ApiParam(name = "teacher", value = "讲师对象", required = true)
                     @RequestBody Teacher teacher){
     teacher.setId(id);
     teacherService.updateById(teacher);
     return R.ok();
}
