英文:
Lombok String Array Property
问题
以下是翻译好的内容：
有没有办法将 JSON 对象中的数组值用作 lombok 值。例如，请求体如下：
{
"associatedCompanyIds": [
332510120384
]
}
转化为：
@lombok.value
private static class Payload {
private List<String> associatedCompanyIds;
}
我知道这样做行不通，但我正在尝试类似这样的操作，以便可以提取数组的第一个值。
英文:
Is there away to use an array value from a JSON object as a lombok value. For example the body
{
"associatedCompanyIds": [
332510120384
]
}
As
@lombok.value
private static class Payload{
private List<String> associatedCompanyIds;
}
I know this won't work, but I'm trying to do something similar to this so that I can extract that first value of the array.

这几乎可以直接使用。您唯一需要做的是告诉 Lombok 生成一个 @java.beans.ConstructorProperties 注解，以便 Jackson 知道要将哪个构造函数参数用于哪个 JSON 值。
只需在项目根文件夹中创建一个名为 lombok.config 的文件，并包含以下内容：
lombok.anyConstructor.addConstructorProperties = true
config.stopBubbling = true
缺点是 Jackson 会传递一个可变的 ArrayList。因此，如果您想要一个真正的不可变值类，您需要使用 lombok 的 @Builder 和 @Singular：
@Builder(setterPrefix = "with")
@JsonDeserialize(builder = Payload.PayloadBuilder.class)
@Value
public class Payload {
@Singular
private List<String> associatedCompanyIds;
}
采用这种方法甚至不需要 lombok.config，但至少需要 lombok 版本为 v1.18.12（因为涉及到 setterPrefix）。
英文:
This works almost out of the box. The only thing you have to do is to advise lombok to generate a @java.beans.ConstructorProperties annotation, so that Jackson knows which constructor parameter to use for which JSON value.
Simply create a lombok.config in your project root folder with this content:
lombok.anyConstructor.addConstructorProperties = true
config.stopBubbling = true
The drawback is that Jackson will pass an ArrayList, which is mutable. So if you want a truely immutable value class, you have to use lombok's @Builder with @Singular:
@Builder(setterPrefix = "with")
@JsonDeserialize(builder = Payload.PayloadBuilder.class)
@Value
public class Payload {
@Singular
private List<String> associatedCompanyIds;
}
You don't even need the lombok.config with this approach, but you need at least lombok v1.18.12 (because of the setterPrefix).
