因此，我使用一个简单的JpaRepository并调用了saveAll（）方法。
hibernate.jdbc.batch_size = 500
hibernate.order_inserts = true
hibernate.generate_statistics = true
运行应用程序后：
8045055 nanoseconds spent acquiring 1 JDBC connections;
0 nanoseconds spent releasing 0 JDBC connections;
137189246 nanoseconds spent preparing 1158 JDBC statements;
1417689514 nanoseconds spent executing 1158 JDBC statements;
0 nanoseconds spent executing 0 JDBC batches;
0 nanoseconds spent performing 0 L2C puts;
0 nanoseconds spent performing 0 L2C hits;
0 nanoseconds spent performing 0 L2C misses;
16270990 nanoseconds spent executing 1 flushes (flushing a total of 1158 entities and 0 collections);
0 nanoseconds spent executing 0 partial-flushes (flushing a total of 0 entities and 0 collections)
谁能看到执行JDBC批处理为0的原因？
另外，我必须指出我的实体具有@GeneratedValue（strategy = IDENTITY）主键
最佳答案
Hibernate不会使用身份标识符生成器执行插入批处理。
