Required arguments with a lombok @Builder

霸气de小男生 提交于 2019-12-09 04:05:43
问题 If I add @Builder to a class. The builder method is created. Person.builder().name("john").surname("Smith").build(); I have a requirement where a particular field is required. In this case, the name field is required but the surname is not. Ideally, I would like to declare it like so. Person.builder("john").surname("Smith").build() I can't work out how to do this. I have tried adding the @Builder to a constructor but it didn't work. @Builder public Person(String name) { this.name = name; }

问题 This question already has answers here : Can't compile project when I'm using Lombok under IntelliJ IDEA (26 answers) Closed last year . I'm trying to introduce Lombok annotations into a Maven Java project in IntelliJ IDEA and followed the steps here and here. @Data annotation (for one) is not being recognized: Here's the relevant Maven stanza: <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.16.18</version> </dependency> </dependencies> I'm on Idea

Gradle build fails on Lombok annotated classes

99封情书 提交于 2019-12-08 15:29:59
问题 I have a JHipster project in which I have added dependency for Lombok in build.gradle: compile group: 'org.projectlombok', name: 'lombok', version: lombok_version And I have the Lombok plugin stalled for IntelliJ. I've turned on annotation processing in IntelliJ, I can build without errors from the IntelliJ IDE, but when I try to build from the command line I get build errors. It seems like Gradle is not processing the annotations and can't find the getter/setter and log declarations. The

Lombok annotations vs code coverage in Cobertura or similar tool

喜夏-厌秋 提交于 2019-12-08 14:58:21
问题 Configure cobertura to ignore certain blocks of code From what I have read from above question, there's no way in Cobertura to exclude given code part from being tested versus having coverage in tests. Is that true? / Is it possible in any simmilar tool? I'm usuing Lombok annotations @Getter , @Setter and so on, which are great, but they result in being 'red' in coverage report, even if I'm testing getter and setter methods. - I would like to do something with that... Is there any way to fix

Getting around Json jackson and lombok constructor requirements

别说谁变了你拦得住时间么 提交于 2019-12-08 03:59:32
Using json to save and load data requires a constructor for json to load the object, and I'm having trouble getting lombok annotations to work with this. What should I do? This is what my class looked like before and after attempting to use an annotation to construct my item: @Data public class Item { //before private int id; private int amount; public Item(@JsonProperty("id") int id, @JsonProperty("amount") int amount) { this.id = id; this.amount = amount; } } @Data @AllArgsConstructor @NoArgsConstructor //I don't want this here as it could cause complications in other places. But json

Parceler and Lombok not working together?

血红的双手。 提交于 2019-12-07 13:11:38
问题 For my android app I use the parceler library and the lombok library. These are the annotations of my class: @Table @ToString @Getter @NoArgsConstructor @Parcel public class MyClass { However, during gradle build, Parceler complains that there is no default empty constructor. So does this mean it doesn't recognize the @NoArgsConstructor annotation and these two simply won't work together? Because e.g. SugarORM has no probs with it. Or am I just missing something? 回答1: This gets into how

java并发编程-12个原子类

背景 多线程更新变量的值,可能得不到预期的值,当然增加syncronized关键字可以解决线程并发的问题。 这里提供另外一种解决问题的方案,即位于 java.util.concurrent.atomic包下的原子操作类,提供了一种用法简单,性能高效,线程安全的更新变量的方式。 其它两个附带的类顺带看了一下: LongAddr 多线程先的sum操作 LongAccomulator 多线程下的函数式操作,性能低于AtomicLong,主要是函数式的支持; 简单分类: 基本类型原子类 使用原子的方式更新基本类型,包括: AtomicBoolean AtomicInteger AtomicLong 核心方法: 直接看源码了。 类签名: public class AtomicInteger extends Number implements java.io.Serializable {} 方法 功能说明 构造方法 两个构造方法,不传或者传入值 get方法 get()获取值;对应的有set(int)方法,layzySet(int) 懒设置 getAndAdd(int) 获得老值然后增加一个数字, 对应的有addAndGet(int)增加一个数字并返回新值 getAndSet(int) 获得老值然后更新为新值 getAndIncreament() 获得老值然后+1
