swagger错误：Failed to execute 'fetch' on 'Window': Request with GET/HEAD method cannot have body

springboot 项目，在swagger页面点击try it out 测试的时候提示“Failed to execute 'fetch' on 'Window': Request with GET/HEAD method cannot have body”

根据这个提示，去找到对于的那个Controller方法，发现@GetMapping请求的方法请求参数却写了个@RequestBody。。。。

这就很尴尬了，粘贴复制代码以后要多注意下，检查好了再启动

解决办法，既然是Get请求，就将参数用@ApiImplicitParams注解

示例：

/**
	 * Description:查询该子账号的用户类型 <br>
	 * @author stf<br>
	 * @param userId,childUserId <br>
	 * @return ObjectRestResponse <br>
	 * @throws Exception <br>
	 * */
	@GetMapping("/getChildUserTypes")
	@ApiOperation(value="查询该子账号的用户类型", notes="查询该子账号的用户类型 ")
	@ApiImplicitParams({
			@ApiImplicitParam(name = "userId", value = "用户id", required = true, dataType = "String", paramType="query"),
			@ApiImplicitParam(name = "childUserId", value = "子账号的用户id", required = true, dataType = "String", paramType="query")
	})
	public ResponseEntity<?> getChildUserTypes(String userId,String childUserId) throws Exception{
            ...
}
