带有自定义分配的RequiredArgsConstructor

我很好奇是否可以在构造函数调用期间使用 @RequiredArgsConstructor 分配自定义值。即

private String value1;
private String value2;
private String value3;

public MyConstructor(String value1, String value2) {
    this.value1 = value1;
    this.value2 = value2;
    this.value3 = createString();
}

相反，我会寻找：

@RequiredArgsConstructor
public class MyConstructor {
    @NonNull
    private String value1;
    @NonNull
    private String value2;
    private String value3;

    private String createString() {
        return "test";
    }
}

I'm curious if it's possible to assign a custom value during a constructor call using @RequiredArgsConstructor. I.e.

private String value1;
private String value2;
private String value3;

public MyConstructor(String value1, String value2) {
    this.value1 = value1;
    this.value2 = value2;
    this.value3 = createString();
}

Instead I'll be looking for:

@RequiredArgsConstructor
public class MyConstructor {
    @NonNull
    private String value1;
    @NonNull
    private String value2;
    private String value3;

    private String createString() {
        return "test";
    }
}

您可以直接在属性的定义中分配createString()。因此，当创建新实例时，value3 也会被初始化。

@RequiredArgsConstructor
public class MyConstructor {
    @NonNull
    private String value1;
    @NonNull
    private String value2;
    private String value3 = createString();

    private String createString() {
        return "test";
    }
}

You can assign createString() directly in the definition of the attribute. Therefore, when a new instance is created, also the value3 is initialized.

@RequiredArgsConstructor
public class MyConstructor {
    @NonNull
    private String value1;
    @NonNull
    private String value2;
    private String value3 = createString();

    private String createString() {
        return "test";
    }
}
