Lombok生成的Getter/Setter无法使用，手动生成则正常

问题概述 #

Spring Boot 3.4.1（Java 21）项目中，JPA实体类Sensor添加Lombok的@Setter、@Getter注解后，编译时调用sensor1.setName("Test")提示找不到方法，构建失败。手动生成Getter/Setter可正常运行，Lombok生成的全参、无参构造函数能正常使用，升级Lombok版本未解决问题。

编译错误信息 #

/Users/coldkey/Downloads/sensorTracker/src/main/java/kz/don/sensorTracker/controller/SensorController.java:23:16java: cannot find symbolsymbol:   method setName(java.lang.String)location: variable sensor1 of type kz.don.sensorTracker.model.Sensor

解决方案 #

• 启用IDEA的注解处理和Lombok插件
  打开IDEA设置（File > Settings），进入Plugins确认Lombok插件已安装启用；再进入Build, Execution, Deployment > Compiler > Annotation Processors，勾选Enable annotation processing。

• 明确指定Lombok版本
  在pom.xml的properties节点添加Lombok版本（Spring Boot 3.4.1推荐使用1.18.34及以上兼容版本）：

  <properties>
      <java.version>21</java.version>
      <lombok.version>1.18.34</lombok.version>
  </properties>
  

  同时在Lombok依赖和maven-compiler-plugin的注解处理器路径中统一使用该版本：

  <dependency>
      <groupId>org.projectlombok</groupId>
      <artifactId>lombok</artifactId>
      <version>${lombok.version}</version>
      <scope>provided</scope>
  </dependency>
  

  <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <configuration>
          <annotationProcessorPaths>
              <path>
                  <groupId>org.projectlombok</groupId>
                  <artifactId>lombok</artifactId>
                  <version>${lombok.version}</version>
              </path>
          </annotationProcessorPaths>
      </configuration>
  </plugin>
  

• 清理缓存并重新构建
  执行Maven命令清理并重新构建：

  mvn clean install -U
  

  同时在IDEA中执行File > Invalidate Caches... > Invalidate and Restart，清除IDE缓存后重启。

• 调整注解顺序
  将@Setter、@Getter放在类的最顶部（优先于@Entity等JPA注解），避免注解处理顺序冲突：

  @Setter
  @Getter
  @Entity
  @Table(name = "SENSORS")
  @AllArgsConstructor
  @NoArgsConstructor
  @Builder
  public class Sensor implements Serializable {
      // ... 类内容
  }
