MySQL itself has no real "batch" API for prepared statements. If you add the configuration property "rewriteBatchedStatements=true" to your JDBC connection string for Connector/J, the driver will rewrite batches of prepared INSERTs into multi-value form, and all other forms of statements into multi-statements, which does give a large performance gain (7-10x).
注意:
jdbc driver 版本需要 5.1.8 及以上
