Java lombok 使用 @Data 遇到 extends 會發生警告要如何處理( Multiple markers at this line)

如果遇到

Multiple markers at this line

就表示你的父類已經有 @Data 了

範例

    @Data
    public static class Val implements OType {
        private String clazz;

        public Val() {
            clazz = this.getClass().getName();
        }
    }

    @Data
    public static class RefVal extends Val {
        private VarLv lv;
        private String name;
    }

這時候就會出現

Multiple markers at this line

如何解決

增加

@EqualsAndHashCode(callSuper = false)

此 Annotation 即可

完整如下

    @Data
    public static class Val implements OType {
        private String clazz;

        public Val() {
            clazz = this.getClass().getName();
        }
    }

    @Data
    @EqualsAndHashCode(callSuper = false)
    public static class RefVal extends Val {
        private VarLv lv;
        private String name;
    }
