用mybatis缓冲结果集

Question

I need to develop a program in java with MyBatis, which reads records from the database and writes them to a file. The query I am using retrieves a large amount of data and there is a risk of OutOfMemoryExceptions .

How do I tell MyBatis to process the records without running out of memory?

Answer 1

根据我在这里看到的文档（ fetchSize ），您似乎可以告诉MyBatis为其基础的JDBC连接使用非默认的获取大小。
