Spring Boot Configuration Annota

IDEA报错后，点开文档内容如下：

B.3 Generating Your Own Metadata by Using the Annotation Processor
You can easily generate your own configuration metadata file from items annotated with @ConfigurationProperties by using the spring-boot-configuration-processor jar. The jar includes a Java annotation processor which is invoked as your project is compiled. To use the processor, include a dependency on spring-boot-configuration-processor.
With Maven the dependency should be declared as optional, as shown in the following example:

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

使用Maven时，依赖项应声明为可选，如以下示例所示：
