[JAVA] How to use Lombok in Spring

Make a note of what you did when using Lombok for Spring

Add as a library

Specify as follows in pom.xml




Precautions for use

Instead of using @Data, use as much as you need (Addition: Because "@Getter, @Setter, @ToString, @EqualsAndHashCode, @RequiredArgsConstructor" will be given together. There is no problem if you use it after understanding it. )

When using @toString in a mutually related class, it loops infinitely, so add the exclude attribute to avoid it.

Postscript (2019/9/6)

When I tried to Maven build the project, the following error was displayed. java.lang.ClassNotFoundException: com.sun.tools.javac.code.TypeTags When I checked it, it looked like a bug and the countermeasures had already been taken, so if I specified 1.16.22, the error was resolved. It was said that it occurred in JDK10, but it also occurred in 1.8. Github:lombok Changed the version of pom.xml from 1.16.18 to 1.18.8.
