使用注解@ConfigurationProperties报错

1，使用注解@ConfigurationProperties报错：Spring Boot Configuration Annotation Processor not found in classpath

解决方式：在pom文件添加：

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

2，添加pom之后报错：Re-run Spring Boot Configuration Annootation Processor to update gennerated

解决方式：Settings --->Build ----> Annottation Processors,重新设置即可
