在springboot maven项目上更改java jdk

Question

我之前使用的是java jdk 17，我用jdk 17构建了我所有的springboots maven项目，但现在我已经在我的笔记本电脑上安装了java jdk 23，然后我尝试运行我的springboot maven项目，它告诉我错误

所以，我尝试将版本从 17 更改为 23，并在 intellij 的项目结构中更改它，但仍然遇到相同的错误

Failed to read candidate component class: file [C:\SpringBoot Projects\springboot-jwt-token-auth\springboot-jwt-token-auth\target\classes\com\abdul\springbootjwttokenauth\config\JwtAuthenticationFilter.class]

和

Unsupported class file major version 67

Answer 1

Update Java Version in Maven Configuration: 

<properties>
    <java.version>23</java.version>
</properties>
Invalidate Caches and Restart IntelliJ: In IntelliJ, go to File > Invalidate Caches / Restart. 

Delete Target Directory: 

mvn clean install

Check for Compatibility with JDK 23:  You may need to update Spring Boot or specific dependencies to ensure compatibility with JDK 23.

Verify JDK in IntelliJ: Go to File > Project Structure > Project and make sure the Project SDK is set to JDK 23. Also, check Modules > Sources to confirm the Language level is compatible with your JDK 23
