Java Could not resolve placeholder 'spring.http.multipart.maxFileSize' in string value

Could not resolve placeholder 'spring.http.multipart.maxFileSize' in string value "${spring.http.multipart.maxFileSize}"

 

 

接手一个java项目，本地一跑就报错了

 

这错误就是

 

@Value("${spring.http.multipart.maxFileSize}")
    private  String maxFileSize;
    @Value("${spring.http.multipart.maxRequestSize}")
    private  String maxRequestSize;

可以暂时改成

@Value("100MB")
    private  String maxFileSize;
    @Value("100MB")
    private  String maxRequestSize;
