java - 如何在 Spring Boot 应用程序中使用 lombok.Data 注解？

Question

我在我的 POJO 类中使用了 @Data 注释，但是没有生成 getter 和 setter。我使用的IDE是sts(Spring Tool Suite)

//User POJO Class
import lombok.Data;

@Data
public class UserVo {

    private String name;
    private String userName;
    private String email;
    private String mobile;
    private String password;
}

Answer 1

这里的问题可能与您检查是否实际生成了 getter/setter 的能力有关。

1. 如果您的 IDE 告诉您未生成 getter/setter - IDE 可能是错误的。它可能不会选择生成了 getters/setters；对于你的 IDE - 确保你有相关的插件。当您提到 STS 时，这很可能是您的问题。尝试与您的案例相关的链接之一:

   • https://projectlombok.org/setup/eclipse
   • https://projectlombok.org/setup/intellij

2. 使用独立于 IDE 的 Maven 构建来确保 Lombok 生成它应该生成的内容。
