我创建了自己的日志目标，如DbTarget，在记录时记录DB中的某些特定信息，但每个执行查询都被其他目标记录。如何禁用它？
目标配置：
public void dls(int limit) {
Set<Integer> visited = new HashSet<>();
int start = 0;
stack.push(start);
display(start);
int depth = 1;
while (!stack.isEmpty()) {
int current = stack.peek();
visited.add(current);
int next = -1;
for (int adj = 0; adj < noOfNodes; adj++) {
if (neighbourMatrix[current][adj] == 1 && !visited.contains(adj)) {
next = adj;
}
}
if (depth <= limit) {
if (next == -1) {
stack.pop();
depth--;
} else {
stack.push(next);
display(next);
depth++;
}
} else {
stack.pop();
depth--;
}
}
}
一些AdvDbTarget方法：

AdvDbTarget扩展了DbTarget。
名为/**
* Stores log messages to DB.
*/
public function export()
{
$this->enableLogging(false); //Here I try to avoid logging of execute info
$tableName = $this->db->quoteTableName($this->logTable);
$sql = "INSERT INTO $tableName ([[level]], [[category]], [[log_time]], [[prefix]], [[message]], [[info]], [[url]], [[application]], [[application_id]], [[user_id]], [[device_id]])
VALUES (:level, :category, :log_time, :prefix, :message, :info, :url, :application, :application_id, :user_id, :device_id)";
$command = $this->db->createCommand($sql);
foreach ($this->messages as $message) {
list($text, $level, $category, $timestamp) = $message;
if (!is_string($text)) {
if ($text instanceof \Throwable || $text instanceof \Exception) {
$text = (string) $text;
} else {
$text = VarDumper::export($text);
}
}
$url = isset($_SERVER['REQUEST_URI'])?$_SERVER['REQUEST_URI']:'';
$application = Yii::$app->id;
$application_id = $this->getApplicationId();
$user_id = $this->getUserId();
$device_id = $this->getDeviceId();
$info = $this->getContextMessage();
$prefix = $this->getMessagePrefix($message);
$command->bindValues([
':level' => $level,
':category' => $category,
':log_time' => $timestamp,
':prefix' => $prefix,
':message' => $text,
':info' => $info,
':url' => $url,
':application' => $application,
':application_id' => $application_id,
':user_id' => $user_id,
':device_id' => $device_id,
])->execute();
}
$this->enableLogging(true);
}
/**
* The method makes commands just like
* Yii::$app->log->targets['query']->enabled = false/true
*
* @param boolean $enable
*/
protected function enableLogging($enable)
{
if (!empty($this->disableTargets)) {
foreach ($this->disableTargets as $target) {
if (isset(Yii::$app->log->targets[$target])) {
$targetObject = Yii::$app->log->targets[$target];
if (!$enable) {
$this->_diasbledTargets[$target] = $targetObject->enabled;
$targetObject->enabled = $enable;
} else {
$targetObject->enabled = $this->_diasbledTargets[$target];
}
}
}
}
}
的目标是从AdvDbTarget记录'query'消息的目标。使用yii\db\Command方法的代码无效。
答案 0 :(得分：0)
解决方案是通过自定义命令类扩展yii\db\Command，重载execute方法而不跟踪＆amp;分析和配置连接，如下所示：$this->db->commandClass = Command::className();
