Looking to use your builder with Jackson, the JSON/XML tool? @Builder.Default functionality was added in lombok v1.16.16. @Builder @Builder注释为你的类生成复杂的构建器API。 lets you automatically produce the code required to have your class be instantiable with code such as: Person.builder().name("Adam Savage").city("San Francisco").job("Mythbusters").job("Unchained Reaction").build(); 直接看官方示例,对比一下就都明白了 @Builder(builderMethodName = "") is legal (and will suppress generation of the builder method) starting with lombok v1.18.8. In this tutorial I show you how to use Project Lombok Builder annotations in Eclipse IDE. You can put the @Builder.ObtainVia annotation on the parameters (in case of a constructor or method) or fields (in case of @Builder on a type) to indicate alternative means by which the value for that field/parameter is obtained from this instance.

I created a pull-request (#1337, hehe) that addresses this issue.I followed the idea of @Krzychek mentioned before: Generate a constructor on the type that takes a builder as a parameter and uses the fields from the builder to set the fields of the new instance. We annotate it with @Builder, instead of the class: This way, we'll be able to access a convenient builder from the Child class, which will allow us to specify also the Parent class' fields: In case the superclass is itself annotated with @Builder, we'll get the following error when annotating the Child class' constructor: The return type is incompatible with Parent.builder(). If lombok cannot singularize your identifier, or it is ambiguous, lombok will generate an error and force you to explicitly specify the singular name. 在我的博客阅读本文1. Either use a star static import: `import static TypeThatHasABuilder. Note that we have to annotate all classes. Calling one of the 'adder' methods, or the 'clear' method, after invoking. For example.

As always, the full source code is available over on Github. Sometimes you use @Builder on a class that inherits from a parent class. 在面向对象的设计里,继承是非常必要的,我们会把共有的属性和方法抽象到父类中,由它统一去实现,而在进行lombok时代之后,更多的打法是使用@Builder来进行对象赋值,我们直接在类上加@Builder之后,我们的继承就被无情的屏蔽了,这主要是由于构造方法与父类冲突的问题导致的,事实 … This only works if you haven't written any explicit constructors yourself. For example, if @Builder is applied to a class named com.yoyodyne.FancyList, then the builder name will be FancyListBuilder. Must explicitly invoke another constructor.

Instead, invoke the generated builder-setter method if you want to set the property inside a custom method inside the builder. The sorted collections (java.util: SortedSet, NavigableSet, SortedMap, NavigableMap and guava: ImmutableSortedSet, ImmutableSortedMap) require that the type argument of the collection has natural order (implements java.util.Comparable). You can use @Builder for copy constructors: foo.toBuilder().build() makes a shallow clone. GitHub Gist: star and fork cherniag's gists by creating an account on GitHub. In some cases, we may need to support deeper inheritance hierarchies. By providing another unique method name in the annotation, we can obtain builders for Parent, Child or Student.

I meet a problem that subclass 's builder() can't override the parentclass 's builder() when i use the @builder annotation. Lombok will not consider fields from the superclass in the generated builder class. For example. Because lombok ensures that generated collections are compacted, a new backing instance of a set or map must be constructed anyway, and storing the data as an ArrayList during the build process is more efficient that storing it as a map or set.
