我目前无法通过java将多查询发送到mysql数据库。代码是这样的：
String query = "Query 1; Query 2; Query 3;... Query 59"
stmt = connection.createStatement();
System.out.println(query);
stmt.execute(query);
然后我收到以下错误：

该代码适用于1个查询（任何查询）。
我已经设置了allowMultiQueries = true，问题也不是数据包太大的问题，因为我只截断了第3个查询并得到了相同的错误。
有任何想法吗？谢谢！
我在spring boot应用程序中遇到了这个问题，发现“mysql-connector-java”版本5.1.6导致了这个问题。我用5.1.45更新了它并解决了这个问题。
我仍然没有答案，但我找到了解决方法。我没有尝试一次执行多个查询并在java中建立事务，而是添加了BEGIN TRANSACTION;查询开头和COMMIT;在末尾。然后我用以下代码执行查询：
stmt = connection.createStatement();
for(int i=0;i<numQueries;i++){
stmt.execute(queries[i]);
}
其中queries []是一个字符串数组，包含我想以适当的顺序执行的查询。这可能不是最佳的，但是，在我的情况下，它做了伎俩。当我在netbeans IDE中执行查询时，我需要大约22秒，而执行上面的代码需要大约25秒。希望人们觉得这很有帮助！
