Cannot resolve symbol 'NotBlank

引用中提到，如果在pom.xml中找不到parent节点，可以手动添加以下配置来解决该问题：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-dependencies</artifactId>
    <version>2.4.5</version>
</parent>

引用中提到，如果遇到爆红错误，可以在pom.xml中添加以下配置来解决该问题：

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

至于你提到的错误`Cannot resolve symbol 'NotBlank'`，它是与AOP操作（使用AspectJ注解）相关的错误。这种错误通常是由于缺少相应的依赖库引起的。你可能需要在pom.xml中添加相应的依赖，例如`spring-boot-starter-aop`:

<dependency>
    <groupId>org.springframework.boot</groupId>
<span class="em">1</span><span class="em">2</span><span class="em">3</span>
