3. 解释为何需要同时生成equals和hashCode方法 在Java中,equals()方法用于比较两个对象是否相等,而hashCode()方法返回一个整数值,该值用作对象的哈希码。当你将对象存储在基于哈希的集合中(如HashMap、HashSet等)时,这两个方法必须保持一致。也就是说,如果两个对象通过equals()方法比较是相等的,
1、lombok警告,没有注入父类的字段 当我们给一个继承了父类的子类上使用@Data @ToString @EqualsAndHashCode 注解时,IDE 会警告 Generating equals/hashCode implementation but without a call to superclass 意思是,该注解在实现 ToString EqualsAndHashCode 方法时,不会考虑父类的属性,通过反编译的源码也是可以看到...
1. 使用@Getter @Setter @ToString代替@Data并且自定义equals(Object other) 和 hashCode()方法,比如有些类只需要判断主键id是否相等即足矣。 2. 或者使用在使用@Data时同时加上@EqualsAndHashCode(callSuper=true)注解。 为什么使用lombok 的@Data 注解的时候会出现警告提示? Generating equals/hashCode implementation ...
