AUTOCOMMIT = 0如果插入查询看起来像这样，在 MySQL 中批量插入数据之前使用（用于性能调整）是否更好

INSERT INTO SomeTable (column1, column2) VALUES (val1,val2),(val3,val4),... ?

我想执行一些语句，并在最后提交整个批处理。我尝试了以下方法：

connection.setAutoCommit(false);            // Don't commit for each statement
int[] returnCodes = pstmt.executeBatch();   // Execute all statements
connection.setAutoCommit(true);             // Back to normal state - future statements
                                            // will be committed instantly
connection.commit();                        // Commit our batch

哪个失败了：

java.sql.SQLException: Can't call commit when autocommit=true
--reference to the line with connection.commit()--

正确的做法是什么？是否connection.setAutoCommit(true)提交所有已执行的批处理语句？
