Lombok generated getters and setters are accessible but don't work


Controller: To the endpoint I sent { "name" : "someSensorName" } json and its supposed to save it

package kz.don.sensorTracker.controller;

import kz.don.sensorTracker.model.Sensor;
import kz.don.sensorTracker.service.SensorService;
import lombok.RequiredArgsConstructor;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/sensors")
@RequiredArgsConstructor
public class SensorController {

    private SensorService sensorService;

    @PostMapping("/registration")
    public Sensor save(@RequestBody Sensor sensor) {
        Sensor sensor1 = new Sensor();
        sensor1.setName("Test");
        return sensorService.save(sensor);
    }

}

Model: Simple Sensor entity with JPA

package kz.don.sensorTracker.model;

import jakarta.persistence.*;
import lombok.*;

import java.io.Serializable;
import java.time.LocalDateTime;

@Setter
@Getter
@Entity
@Table(name = "SENSORS")
@AllArgsConstructor
@NoArgsConstructor
@Builder
public class Sensor implements Serializable {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "ID")
    private Long id;

    @Column(name = "NAME", nullable = false, unique = true)
    private String name;

    private LocalDateTime initDate;

    @PrePersist
    public void prePersist(){
        initDate = LocalDateTime.now();
    }

}

pom.xml: I tried to specifically provide newer version of lombok to tackle the problem, yet nothing changed.

/Users/coldkey/Downloads/sensorTracker/src/main/java/kz/don/sensorTracker/controller/SensorController.java:23:16java: cannot find symbolsymbol:   method setName(java.lang.String)location: variable sensor1 of type kz.don.sensorTracker.model.Sensor

build failed - thats the whole stack trace

With manually IDEA generated getters and setters it works perfectly however the IDEA itself suggests to use lombok.

The error occurs every time I try to use methods generated by lombok, however the constructor works okay with all-args and no-args ones.


Solution

  • Following @shshi009, once you are on this setting panel (Build,Execution,Deployment > Annotation Processors) select your application module and in the right side activate "Obtain processors from project classpath" - which is deactivated by default.
