##问题

@Data@Builderpublic class Demo {    @Tolerate    public Demo(){    }    private int type = 2;    private String url;}

通过builder模式，如果不设置type，还指望它能够设置2，恐怕要令你失望了。

##告警

Warning:(95, 30) java: @Builder will ignore the initializing expression entirely. If you want the initializing expression to serve as default, add @Builder.Default. if it is not supposed to be settable during building, add @Builder.Constant.

      lombok

@Builder.Defaultprivate int type = 2;

这样就ok了。
