Spring jpa entity and Lombok

Question

I've created project with spring.

dependencies {
    compile('org.springframework.boot:spring-boot-starter-cache')
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    compile('org.springframework.boot:spring-boot-starter-data-rest')
    compile('org.springframework.boot:spring-boot-devtools')
    compile('org.projectlombok:lombok')
    compile('org.springframework.boot:spring-boot-starter-thymeleaf')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.codehaus.groovy:groovy')
    runtime('com.h2database:h2')
    runtime('mysql:mysql-connector-java')
    testCompile('org.springframework.boot:spring-boot-starter-test') 
    testCompile('org.springframework.restdocs:spring-restdocs-mockmvc')
}

application.properties:

spring.data.rest.base-path=/api

spring.datasource.url=jdbc:mysql://localhost/secret_backend
spring.datasource.username=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update

And the entity class:

package com.app.Entity

import lombok.Data

import javax.persistence.Entity
import javax.persistence.GeneratedValue
import javax.persistence.Id
import javax.persistence.Table

@Data
@Entity
@Table(name = "cities")
public class City {

    private @Id @GeneratedValue Long id;
    private String slug;
    private String title;
    private String titleShort;

    private City() {}

    /*public String getSlug(){
        return slug;
    }*/

    public City(String slug) {
        this.slug = slug;
    }
}

When I'm navigating to localhost:8080/api/cities, I don't see actual data form database:

{
  "_embedded": {
    "cities": [
      {
        "_links": {
          "self": {
            "href": "http://localhost:8080/api/cities/7"
          },
          "city": {
            "href": "http://localhost:8080/api/cities/7"
          }
        }
      },
      {
        "_links": {
          "self": {
            "href": "http://localhost:8080/api/cities/8"
          },
          "city": {
            "href": "http://localhost:8080/api/cities/8"
          }
        }
      },
...

Only if I'm adding getters to entity I see the data, but from lombok documentation @Data annotation must generate getters and setters for all entity properties.

Did you check the actual output? Did lombok instrument the classes? Also, lombok is only needed for compilation time not runtime. — highstakes
Actual output? Maybe some info for java(spring) dummy? And lombok is in compile('org.projectlombok:lombok') — Cawa
I mean, check the compiled .class files and see if the methods have been added into them (use a java decompiler or the 'javap' command on it). Compile dependency means it will be included in the produced artifact, this would be provided scope (which you need a plugin for in gradle) though this is unimportant. — highstakes
I've checked compiled entity, and theres no getters and setters pastie.org/10759960 So it seems that lombock is not working — Cawa
You should try running lombok in isolation on your class. It is an annotation preprocessor which could interfere with other preprocessors if done incorrectly. — highstakes

Renamed City.groovy to City.java, and now it working fine. Thanks to @highstakes
