我最近将我的应用程序切换到 Spring Boot 2。我依靠 Spring Data JPA 来处理所有事务，我注意到这与我的旧配置之间存在巨大的速度差异。大约 6 秒内完成了大约 1000 个元素的存储，现在需要超过 25 秒。我看过有关使用 Data JPA 进行批处理的 SO 帖子，但这些帖子都没有奏效。

让我向您展示两种配置：

实体（两者共有）：

    @Entity
    @Table(name = "category")
    public class CategoryDB implements Serializable
    {
        private static final long serialVersionUID = -7047292240228252349L;

        private String category_id;

        @Column(name = "category_name", length = 50)

        private String pluralName;

        @Column(name = "url_icon", length = 200)
        private String url;

        @Column(name = "parent_category", length = …
