在SpringBoot中找不到符號(所有建構式、getter和setter)

2022-01-21 18:43:22 前端設計

我的專案早些時候運行良好,但是當我在 STS 中打開它然后在 IntelliJ 中打開它時,它開始給我這個錯誤。我正在尋找解決方案,但沒有得到任何解決方案。任何人,請幫助我。

另外,我已經在 IntelliJ 中安裝了 Lombok 插件

uj5u.com熱心網友回復:

對于 IntelliJ Idea,使用 Lombok 時,您必須啟用注釋處理。

  • 首選項 ( Ctrl Alt S)
    • 構建、執行、部署
      • 編譯器
        • 注釋處理器
          • 啟用注釋處理

如果問題仍然存在:

添加版本 1.18.16。

<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.16</version> 
<scope>provided</scope>
