在IntelliT Idea for Kotlin @ConfigurationProperties类中不生成spring-configuration-metadata.json文件

问题描述

我正在尝试为基于Spring Boot的项目生成spring-configuration-metadata.json文件。如果我使用Java @ConfigurationProperties 类，它会自动生成并自动生成：

I'm trying to generate spring-configuration-metadata.json file for my Spring Boot based project. If I use Java @ConfigurationProperties class it is generated correctly and automatically:

@ConfigurationProperties("myprops")
public class MyProps {

    private String hello;

    public String getHello() {
        return hello;
    }

    public void setHello(String hello) {
        this.hello = hello;
    }
}

但如果我使用Kotlin类春天未生成-configuration-metadata.json 文件（我已尝试 gradle build 和Idea 重建项目）。

But if I use Kotlin class the spring-configuration-metadata.json file is not generated (I've tried both gradle build and Idea Rebuild Project).

@ConfigurationProperties("myprops")
class MyProps {
    var hello: String? = null
}

AFAIK Kotlin使用构造函数，getter和setter生成相同的类，并且应该充当常规Java bean。

AFAIK Kotlin generates the same class with constructor, getters and setters and should act as regular Java bean.

为什么 spring-boot-configuration-processor 不适用于Kotlin类的任何想法？

Any ideas why spring-boot-configuration-processor doesn't work with Kotlin classes?

推荐答案

感谢您指点我正确的方向。因此解决方案是添加

Thank you for pointing me in the right direction. So the solution is to add

dependencies {
    ...
    kapt "org.springframework.boot:spring-boot-configuration-processor"
    optional "org.springframework.boot:spring-boot-configuration-processor"
    ...
}

到 build.gradle 文件，在命令行中运行 gradle compileJava 并打开注释IntelliJ Idea设置中的处理构建，执行，部署 - >编译器 - >注释处理器 - >启用anotation处理。其余配置仍然是

to build.gradle file, run gradle compileJava in command line and turn on annotation processing in IntelliJ Idea settings Build, Execution, Deployment -> Compiler -> Annotation processor -> Enable anotation processing. The rest of configuration remains the same

另请注意，没有此行

optional "org.springframework.boot:spring-boot-configuration-processor"

IntelliJ Idea会抱怨whith

IntelliJ Idea will complain whith

$ application.properties 或 application.yml
