Lombok

问题 I'm using the Lombok Plugin for IntelliJ IDEA. When try to run Java code using the var keyword, I get the following error: Use of var is disabled by default. Please add 'lombok.var.flagUsage = ALLOW' to 'lombok.config' if you want to enable is. How do you do that in IntelliJ IDEA ? I created the lombok.config in the project root and pasted lombok.var.flagUsage = ALLOW but it didn't fix it. val is working but not var . I can't seem to find clear instructions on enabling var .

问题 So, after updating eclipse from Helios to Kepler, I found my Lombok-dependent project to be full of errors, due to eclipse not seeing the added methods by @Getter and stuff, so i reinstalled Lombok, however eclipse either crashed or just didnt see the methods, depending on how i run it. If I ran it from eclipse.exe from windows explorer, it starts without lombok, and if i type it into the run dialog it just crashes like this: Java was started but returned exit code=1 C:\Windows\system32\javaw

问题 Jackson can deserialize json for the following class in 2.6.5 but fails in 2.8.8.

问题 I wrote a Custom Serializer and Custom Deserializer to serialize properties marked with @Confidential annotation. @Data public class Person { private String name; @Confidential private String address; } The Custom Serializer serializes a POJO with following values: { "name": "John Doe", "address": "Kearney St"} as follows: {"name":"John Doe", "address": {"value":"IjIwMzEwIDU4dGggTG4gTkUi"}} The Custom Deserializer is also able to deserialize the JSON back to the Person POJO fine. However,

问题 I am writing a simple app: @Slf4j public class MyApp { public static void main(String[] argv) { log.info("hello world!"); } } This code compiles just fine, and indeed, when run I see "hello world!" being logged out. Intellij however doesn't agree this works. I am constantly getting "Cannot resolve symbol log" even though this works and it compiles. Here's what I have done: I have installed the latest Lombok plugin I have enabled annotation processing All other Lombok annotations seem to work

问题 Intellij doesn't recognize @SLF4J annotation. I have the following error: Error:(105, 9) java: cannot find symbol symbol: variable log location: class com.xxxxx.SdsConfig knowing that I have already Enable annotation processing (Settings -> Compiler -> Annotation Processors) I use java 8 compiler. 回答1: Use lombok plugin for Intellij: https://plugins.jetbrains.com/plugin/6317 This will highlight everything correctly and allow you to use auto completion for generated methods.

问题 After upgrading SonarQube from 4.0 to 4.2, I got a bunch of 'Unused private fields should be removed' errors from the classes with Lombok annotations. I have @SuppressWarnings("PMD.UnusedPrivateField") declared at the beginning of all those classes. It worked fine when I was using SonarQube 3.7 and 4.0. I use mvn sonar:sonar to generate the SonarQube report. And this shows how my class look like: @Data @SuppressWarnings("PMD.UnusedPrivateField") public class MyClass { private String field; }

问题 I've recently been working with Lombok--and I'm wondering it would be possible to provide a class level or method level annotation that adds final to all parameters. For example: @finalizer void foo(Bar bar); Becomes void foo(final Bar bar); 回答1: It is possible. Lombok could do it, there's already the FieldDefaults annotation allowing to make all fields final by default. Doing this for parameters would be even easier. While final on fields is something the JVM deals with (by not allowing
