Spring Boot Configuration Annotation Processor not configured

这个错误通常表示你的项目缺少了必要的依赖或者配置。

首先，你需要检查你的pom.xml文件，确保以下依赖被添加：

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

如果依赖已经存在，那么你需要检查你的IDE是否支持注解处理器。如果你使用的是IntelliJ IDEA，你需要在"Preferences" -> "Build, Execution, Deployment" -> "Compiler" -> "Annotation Processors"中勾选"Enable annotation processing"选项。

如果你使用的是Eclipse，你需要在"Project properties" -> "Java Compiler" -> "Annotation Processing"中勾选"Enable annotation processing"选项。

完成以上步骤后，重新编译你的项目，应该就能够正常运行了。

Spring Boot Configuration AnnotationProcessor not configured

The error message "Spring Boot Configuration AnnotationProcessor not configured" typically occurs when you're missing the necessary dependencies or configurations for annotation processing in your Spring Boot project. Here are a few steps you can take to resolve this issue:

1. Make sure you have the necessary dependencies in your project's build file (e.g., pom.xml for Maven or build.gradle for Gradle). You'll need to include the following dependency:

For Maven:

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

For Gradle:

   implementation 'org.springframework.boot:spring-boot-configuration-processor'

2. Verify that your project's configuration class is annotated with `@Configuration` or `@SpringBootApplication`. This annotation is required for Spring Boot to perform the necessary annotation processing.

3. Ensure that your IDE is properly configured to support annotation processing. In IntelliJ IDEA, go to `Settings/Preferences -> Build, Execution, Deployment -> Compiler -> Annotation Processors` and make sure "Enable annotation processing" is checked.

4. Clean and rebuild your project to ensure that all necessary classes and configurations are properly processed.

5. If you're using an older version of Spring Boot, consider upgrading to the latest stable version, as newer versions often include bug fixes and improvements related to annotation processing.

By following these steps, you should be able to resolve the "Spring Boot Configuration AnnotationProcessor not configured" error.
