我正在尝试运行jdbc查询。这是我的代码

 Timestamp timeStamp = new Timestamp(svnLog.getTime().getTime());

 String query = "Insert into transaction (RevisionId, AuthorId, LogMessage, Time) values (?,?,?,?) ";


    System.out.println("The query is " + query + svnLog.getRevisionId() + "," + svnLog.getAuthorId() + "," + svnLog.getLogMessage() + "," + timeStamp);

    try {

        PreparedStatement stmt = connManager.getConnection().prepareStatement(query);
        stmt.setLong(1, svnLog.getRevisionId());
        stmt.setString(2, svnLog.getAuthorId());
        stmt.setString(3, svnLog.getLogMessage());
        stmt.setTimestamp(4, timeStamp);

        System.out.println("After binding " + stmt.toString());

这会引发以下异常。

   After binding com.mysql.jdbc.PreparedStatement@478e4327: Insert into transaction   (RevisionId, AuthorId, LogMessage, Time) values (214,'mknauer','Initial import.','2007-03-01 06:39:21.128') 
   com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '?,?,?,?)' at line 1

我在绑定后打印了准备好的声明。我在命令行上运行时打印的查询工作正常。我在其他一些帖子中看到了这个错误,其中解决方案是更改my.cnf文件以进行字符编码。我将这两行添加到此文件

character_set_server=utf8
collation_server=utf8_general_ci

它没有解决错误。
