Lombok

问题 I'm using project lombok for the first time and I have problems compiling the project via maven when I run the build I receive errors where methods annotated with project lombok annotations are called. This is the annotated parameter: private @Getter @Setter String paymentNonce = null; and in this line for example the maven breaks the build: if (!StringUtilities.isNullOrEmpty(getPaymentNonce())) { this is my maven dependency <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok

问题 I have a class called Address which looks like this: @Value class Address { @NotNull String userId; @NotNull String line1; String line2; private Address(Builder b) { // copy everything from builder } // override getter for line2 so that it returns Optional<String> public Optional<String> getLine2() { return Optional.ofNullable(this.line2); } // and a Builder public static class Builder { // builder methods } } Here I am forced to write Builder and a Getter because, if I want to return an

问题 I have a problem with my project. It is an Spring CRUD RestFul API that expose services witch are providing Json datas. I use JDK-7, Eclipse-Neon and Maven to code, build and the project is deployed into a JBossEAP 6.4 server. Every thing is working well, the services are responding correctly. So I decide to add Lombok, to reduce the boiler code and improve the readability of the code. By the way I used Lombok on an another project before and is worked fine. Here is my problem, after

问题 I want to use a data class in Lombok. Since it has about a dozen fields, I annotated it with @Data in order to generate all the setters and getter. However there is one special field for which I don't want to the accessors to be implemented. How does Lombok omit this field? 回答1: You can pass an access level to the @Getter and @Setter annotations. This is useful to make getters or setters protected or private. It can also be used to override the default. With @Data , you have public access to

问题 Lets say I have a lombok annotated class like @Builder class Band { String name; String type; } I know I can do: Band rollingStones = Band.builder().name("Rolling Stones").type("Rock Band").build(); Is there an easy way to create an object of Foo using the existing object as a template and changing one of it's properties? Something like: Band nirvana = Band.builder(rollingStones).name("Nirvana"); I can't find this in the lombok documentation. 回答1: You can use the toBuilder parameter to give

问题 I am trying to add groovy to an existing Java Maven project that leverages Lombok. Unfortunately when I enable the groovy-maven-eclipse compiler with the pom fragment below, my lombok annotated java files fail to compile. As far as I can tell, Lombok is not participating in the compilation of java files at all. <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>2.3.1</version> <configuration> <compilerId>groovy-eclipse-compiler</compilerId> <verbose>true</verbose> <

问题 I am using Java lombok annotation @Getter to generate getters for my POJO. I have a 'boolean' field by the name 'isAbc'. The @Getter annotation in this case generates a method by the name 'isAbc()'. Shouldn't it generate a method by the name 'isIsAbc()'? 回答1: Read the 'small print' section on the lombok page https://projectlombok.org/features/GetterSetter.html For boolean fields that start with is immediately followed by a title-case letter, nothing is prefixed to generate the getter name. So

问题 I upgraded recently to the new Eclipse version (Oxygen). I downloaded the lombok.jar from the website and installed it. This is how the eclipse.ini looks like after installation: -startup plugins/org.eclipse.equinox.launcher_1.4.0.v20161219-1356.jar --launcher.library C:\Users\xxx\.p2\pool\plugins\org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.500.v20170531-1133 -product org.eclipse.epp.package.jee.product -showsplash org.eclipse.epp.package.common --launcher.defaultAction openFile -

问题 I have a class @Value @NonFinal public class A { int x; int y; } I have another class B @Value public class B extends A { int z; } lombok is throwing error saying it cant find A() constructor, explicitly call it what i want lombok to do is to give annotation to class b such that it generates the following code: public class B extends A { int z; public B( int x, int y, int z) { super( x , y ); this.z = z; } } Do we have an annotation to do that in Lombok? 回答1: This is not possible in Lombok.
