How to use lombok.Data annotation in a Spring Boot application?

Question

I have used @Data annotation in my POJO Class but the getters and setters are not generated. IDE which I am using is sts(Spring Tool Suite)

//User POJO Class import lombok.Data;  @Data public class UserVo {      private String name;     private String userName;     private String email;     private String mobile;     private String password; }

Answer 1

The problem here is likely related to your ability to check if getters/setters were actually generated.

1. If your IDE tells you getters/setters not generated - the IDE might be wrong. It may not pick that getters/setters were generated; For your IDE - make sure you have relevant plugins for that. This is most likely your issue as you are mentioning STS. Try one of links relevant to your case:

   • https://projectlombok.org/setup/eclipse
   • https://projectlombok.org/setup/intellij

2. Use IDE-independent Maven build to make sure that Lombok generates what it is supposed to.

Answer 2

For Maven:

<dependency>     <groupId>org.springframework.boot</groupId>     <artifactId>spring-boot-devtools</artifactId>     <scope>runtime</scope> </dependency>  <dependency>     <groupId>org.projectlombok</groupId>     <artifactId>lombok</artifactId>     <optional>true</optional> </dependency> 

For Gradle:

developmentOnly 'org.springframework.boot:spring-boot-devtools' compileOnly 'org.projectlombok:lombok' annotationProcessor 'org.projectlombok:lombok'
