Question

有没有办法在执行前记录Anorm语句。目前我正在通过JDBC驱动程序技巧记录语句：

application.conf：

db.default.driver="com.mysql.jdbc.Driver"
db.default.url="jdbc:mysql://someDBServer/db?useUnicode=true&characterEncoding=utf8&autoReconnect=true&logger=com.mysql.jdbc.log.Slf4JLogger&profileSQL=true"
db.default.logStatements=true

但是我想在执行之前记录语句，以便进行调试和记录。例如，我的sql语法有错误，我使用Hickary CP（2.5.x Playframework）

日志输出无效：

2017-01-23 16:37:01  application-akka.actor.default-dispatcher-3 [INFO ] controllers.AppController  - com.mysql.jdbc.exceptions.jdbc4.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

Println也没有帮助：

  db.withConnection { implicit c =>
    def sql = SQL("delete from USER where (username = {username} or username = {org_jed }) and id = {id}").on(
      'username -> user.username,
      'org_jed -> user.org_jed,
      'id -> some.id
    )
    println("Statement: " + sql.preparedStatement(c))

    sql.executeUpdate()
  }

执行前的Anorm日志语句
