如何在使用lombok调用Java class或Java接口时访问getter方法？

Question

Using JDK 1.8 and the following lombok version:

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.12</version>
    <scope>provided</scope>
</dependency>

Have the following Java interface:

package com.myapp.bridge;

public interface MyBridge {
    
    public void run();

}

---

Implementing class:

package com.myapp.bridge;

import lombok.Getter;
import lombok.Setter;

public class MyBridgeHandler implements MyBridge {
    
    @Getter(AccessLevel.PACKAGE)
    @Setter(AccessLevel.PACKAGE)
    public String value;

    public void run() {

        String msg = "hello";
        setValue(msg);
        
        // This works and prints hello ten times.
        for (int i = 0; i < 10; i++) {
           System.out.println(getValue());
        }

    } 
}

---

Calling class:

package com.myapp.bridge;

import lombok.Getter;

public class App {
    
    @Getter 
    private MyBridge bridge = new MyBridgeHandler();

    public void printValue() {
        // IntelliJ IDEA doesn't seem to let me access this getter? 
        String aValue = getBridge().getValue();
        System.out.println(aValue); 
    }

    public static void main(String args []) {
        App app = new App();
        app.printValue();

    }
} 

---

Question(s):

1. How do I obtain / access the MyBridgetHandler.getValue() method inside my calling class (IntelliJ IDEA's code completion doesn't even display / or opt for this method after I put a dot after getBridge(). inside my printValue method)?

2. Should it be placed inside the MyBridge interface? If so, how would the implementation look like?

---

Note, this is not an IntelliJ specific question as my other POJOs have lombok-based @getter & @setter annotations and work inside calling classes via IntelliJ IDEA.

Am able to see hello be printed to stdout 10 times so it is getting set.

Seems like a visibility / accessibility issue.

Answer 1

Fixed / found the solution...

Inside the MyBridge interface, I added the following method:

package com.myapp.bridge;

public interface MyBridge {
    
    public void run();
  
    String getValue();
}

---

Implemented it like this inside MyBridgeHandler Java class:

package com.myapp.bridge;

import lombok.Getter;
import lombok.Setter;

public class MyBridgeHandler implements MyBridge {
    
    @Setter(AccessLevel.PACKAGE)
    public String value;

    public void run() {

        String msg = "hello";
        setValue(msg);
        
        // This works and prints hello ten times.
        for (int i = 0; i < 10; i++) {
           System.out.println(getValue());
        }
    } 

    public String getValue() {
        return value;
    } 
}

---

Voila! I am able to access it now inside the App.printValue() method.
