没有找到带有休眠 4 的龙目岛的属性

【问题标题】：property not found lombok with hibernate 4没有找到带有休眠 4 的龙目岛的属性
【发布时间】：2014-12-06 19:50:44
【问题描述】：

我正在使用 lombok 1.14.8 和 Hibernate 4.2.0。 我注释了模型类，如下所示：

@Getter
@Setter
@Entity
public class Employee {

@Id
@Column(name="pk_id")
@GeneratedValue(strategy=GenerationType.AUTO)
private Integer employeeId;

@Column(name="name")
private String name;

@Column(name="salary")
private double salary;

@Column(name="birth_date")
private Date birthDate;

@Column(name="hire_date")
private Date hireDate;

@ManyToOne
@JoinColumn(referencedColumnName="pk_id", name="fk_dept_id")
private Department department;

@Column(name="marital_status")
private Integer maritalStatus;

@Column(name="job_title")
private String jobTitle;
}

在运行应用程序时，我得到 property not found 异常，这样我就没有 getter 和 setter。

当添加普通的 getter 和 setter 时，它可以正常工作，但我必须使用 lombok。 这是一个例外：

感谢您的帮助:)

编辑 .class 文件不包含 getter 和 setter lombok 不会生成它们。

【问题讨论】：

  • 抱歉忘了说……它是 Eclipse Luna

标签： hibernate spring-mvc setter getter lombok


【解决方案1】：

解决办法是这样的：

Unix 用户

  1. 首先，关闭 Eclipse IDE。
  2. cd 到 Lombok.jar 包的文件夹。
  3. un java -jar lombok.jar.
  4. 将显示一个 GUI。指定 Eclipse luna 的位置
  5. 点击安装/更新按钮
  6. 玩得开心

Windows 用户

  1. 请关闭您的 Eclipse IDE
  2. 双击lombok.jar
  3. 指定 Eclipse 的位置
  4. 点击安装/更新按钮
  5. 玩得开心

希望这会有所帮助。萨拉姆
