[英]Cannot resolve spring annotations in intellij idea
我下载了 jdk 11 和 maven 3.6.3 和 Itellj Idea 并导入了一个项目:
mvn clean install
但我总是得到这个错误:
Cannot resolve symbol 'SpringBootApplication'

我试图删除.idea
文件夹或“无效缓存并重新启动”,但第一种方法和第二种方法都没有解决问题。 有一个类似的问题Cannot resolve symbol SpringApplication但答案没有解决我的问题。 我该如何解决?
运行以下命令为我解决了这个问题:
mvn idea:idea
我通过降级 maven 版本解决了这个问题。
您似乎使用 Spring Boot version 1.0.1,@SpringBootApplication annotation 在 1.2 中引入
您没有使用 SpringBoot parent 而是您自己的,您需要添加依赖项:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>${spring-boot.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
你需要添加依赖
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.3.0.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
