JAVAPreparedStatement参数值出现在查询中

Question

我搜索了很多如何记录JAVAPreparedstatement参数值，例如

prepStmt.setString, prepStmt.setInt,.... etc.

我知道这个问题似乎之前已经解决了，但实际上通过打印 prepStmt 来回答的问题并不适用于我之前尝试过的所有 JDBC 驱动程序。

Answer 1

我已采取解决方法来解决此问题。

解决方案:

// Initialize connection
PreparedStatement prepStmt = connection.prepareStatement(sql);

PreparedStatementHelper prepHelper = new PreparedStatementHelper(prepStmt);

// User prepHelper.setXXX(indx++, value);
// .....

try {
   Pattern pattern = Pattern.compile("\\?");
   Matcher matcher = pattern.matcher(sql);
   StringBuffer sb = new StringBuffer();
   int indx = 1;  // Parameter begin with index 1
   while (matcher.find()) {
 matcher.appendReplacement(sb, prepHelper.getParameter(indx++));
   }
   matcher.appendTail(sb);
   LOGGER.debug("Executing Query [" + sb.toString() + "] with Database[" + /*db name*/ + "] ...");
   } catch (Exception ex) {
    LOGGER.debug("Executing Query [" + sql + "] with Database[" +  /*db name*/+ "] ...");
}
