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 Annotation Processor not configured

To configure the Spring Boot Configuration Annotation Processor, you need to follow these steps:

1. Add the required dependencies to your project's build file, such as Maven or Gradle.

For Maven, add the following dependency to your `pom.xml` file:

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

For Gradle, add the following dependency to your `build.gradle` file:

dependencies {
    // other dependencies
    annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor'
}

2. Ensure that your Spring Boot version supports the Configuration Annotation Processor. Starting from Spring Boot 1.2.0, the Configuration Annotation Processor is automatically enabled.

3. Make sure that you have the necessary annotations in your code. The Spring Boot Configuration Annotation Processor processes annotations such as `@ConfigurationProperties`, `@Value`, and `@Validated`.

4. Build your project to trigger the annotation processing. The Configuration Annotation Processor will generate the necessary metadata for your configuration properties.

By following these steps, you should be able to configure and use the Spring Boot Configuration Annotation Processor in your project.
