Eclipse JPA Facet生成实体导入错误，如何配置默认持久化类？

我在使用Eclipse 2023-03从现有数据库生成JPA实体时遇到问题：添加JPA Facet后生成的类结构正确，但导入语句错误，生成的是import javax.persistence.*;，而预期应为import jakarta.persistence.*;。我的项目是Spring Boot 3.0.6 starter项目，pom.xml依赖如下：

生成的实体类示例：

import java.io.Serializable;
import javax.persistence.*;

@Entity
@Table(name="teams")
@NamedQuery(name="Team.findAll", query="SELECT t FROM Team t")
public class Team implements Serializable {

预期的实体类示例：

import java.io.Serializable;
import jakarta.persistence.*;

@Entity
@Table(name="teams")
@NamedQuery(name="Team.findAll", query="SELECT t FROM Team t")
public class Team implements Serializable {

解决方案：配置JPA Facet使用Jakarta Persistence #

• 右键项目 → Properties
• 左侧菜单选择 Project Facets，找到JPA选项，点击右侧的Configure...
• 在JPA配置窗口中，修改Platform下拉选项：
  • 选择支持Jakarta Persistence的平台，比如Hibernate 6.x（Spring Boot 3默认适配该版本）
  • 若列表中无对应平台，点击**Download...**下载安装
• 确认Default persistence provider选择的是支持Jakarta的实现（如Hibernate 6.x）
• 点击Apply and Close，重新生成JPA实体

补充：修改persistence.xml（若存在） #

如果项目中有persistence.xml文件，确保其命名空间使用Jakarta规范：

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="3.0" xmlns="https://jakarta.ee/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="https://jakarta.ee/xml/ns/persistence https://jakarta.ee/xml/ns/persistence/persistence_3_0.xsd">
    <!-- 此处配置你的persistence单元 -->
</persistence>
