springBoot 整合log4j 2 在訪問介面文件的時候會出現下面這個錯誤

java.lang.NumberFormatException: For input string: ""

後端原始介面

 @ApiOperation(value = "根據id獲取使用者")
    @GetMapping("{id}")
    public ApiResult getUser(@ApiParam(name = "id", value = "使用者id",required = true) @PathVariable("id") Long id) {
        SysUser sysUser = sysUserService.getUser(id);
        return ApiResult.ok(sysUser);
    }

分析原因:

原因就是引數沒有預設值,需要一個long,但是空值預設為""

解決方式:

在介面中新增預設值example屬性值:

 @ApiOperation(value = "根據id獲取使用者")
    @GetMapping("{id}")
    public ApiResult getUser(@ApiParam(name = "id", value = "使用者id",example = "120",required = true) @PathVariable("id") Long id) {
        SysUser sysUser = sysUserService.getUser(id);
        return ApiResult.ok(sysUser);
    }
