Springboot--Cannot prompt about the yml of custom stater

1 Introduction

I encountered a similar situation when building the architecture in the past. When using the @EnableConfigurationProperties annotation, no matter what, the properties in the properties were not automatically prompted when the starter was introduced in the project.

@Data
@ConfigurationProperties(prefix = "properties")
public class DefaultProperties {

    @NestedConfigurationProperty
    public SwaggerProperties swagger;
}

--------以上为properties
properties:
  swagger:
    type: service
    packages: com.wsq.controller
    api-tittle: 'swagger文档'
    service-url:
    writer-name: 'wangqueyue'
    version: '1.0.0'
------无法识别，只能一个个的敲击。

2.Solution

2.1Introduce dependency packages

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-configuration-processor</artifactId>
	<optional>true</optional>
</dependency>

2.2 Placement idea

The creation of spring-configuration-metadata.json is explained online. This file is too cumbersome and it is almost impossible to write it manually, so here is a simple generation method. You only need to modify it after generation.

setting>Build,execution,deployment>Compiker>Annotation Processors

Check Enable annotation processing

2.3 Package and compile starter (key points)

You must use maven clean when compiling, otherwise the things you compiled and packaged last time were wrong and you still thought they were correct.
Then maven compile (remember, the type of starter must be jar, not pom)
maven install, the project must be packaged into a local service.

In the target directory, a spring-configuration-metadata.jsonfile will be generated. There is no need to create it manually. Some files you create in the starter will still be invalid without packaging.

2.4additional-spring-configuration-metadata.json file creation

This file is a supplementary explanation to the previous file, and the creation method is also very simple.

Copy the files in the target directory spring-configuration-metadata.jsonto resourcethe directory below META-INF. It does not need to be created directly.
Change the file to the name of the title and continue maven clean, compile, and install.
A additional-spring-configuration-metadata.jsonfile will be generated in the target directory, so the supplementary file is completed.
