我的Spring Boot应用程序中有以下预定的代码：
switch (what) {
case Android.Media.MediaInfo.BufferingStart:
//AppLog.showLogE(TAG,"Buffering...");
progressView.Visibility=(ViewStates.Visible);
break;
case Android.Media.MediaInfo.BufferingEnd:
//AppLog.showLogE(TAG,"Buffering End");
progressView.Visibility=(ViewStates.Gone);
break;
}
在我的private static String getWithoutRepetitions(String sentence){
String result = sentence;
String[] allWords = (sentence.replaceAll(",", " ").replaceAll("\\.", " ")).split(" ");
HashMap<String, Integer> pairs = new HashMap<>();
for(String s : allWords){
if(pairs.get(s) == null && s != null){
pairs.put(s, 1);
}else{
pairs.put(s, pairs.get(s)+1);
}
}
for (Entry<String, Integer> entry : pairs.entrySet()) {
String key = entry.getKey();
Integer value = (Integer) entry.getValue();
if(value > 1){
result = result.replaceAll(key, "");
}
}
result = result.trim().replaceAll(" +", " ");
return result;
}
组件中，<?php
$con = mysqli_connect("****", "****", "*****", "*****");
$id = $_POST["ID"];
$paxfwdcabin = $_POST["PAXFWDCABIN"];
$paxmidcabin = $_POST["PAXMIDCABIN"];
$paxaftcabin = $_POST["PAXAFTCABIN"];
$forwardhold1 = $_POST["FORWARDHOLD1"];
$forwardhold2 = $_POST["FORWARDHOLD2"];
$afthold3 = $_POST["AFTHOLD3"];
$childadjustments = $_POST["CHILDADJUSTMENTS"];
$statement = mysqli_prepare($con, "SELECT * FROM RyanAirCWBalance WHERE ID = ? ");
mysqli_stmt_bind_param($statement, "i", $id);
mysqli_stmt_execute($statement);
mysqli_stmt_store_result($statement);
mysqli_stmt_bind_param($statment, $id, $paxfwdcabin, $paxmidcabin, $paxaftcabin, $forwardhold1, $forwardhold2, $afthold3, $childadjustments);
$response = array();
$response["success"] = false;
while(mysqli_stmt_fetch($statement)) {
$response["success"] = true;
$response["ID"] = $id;
$response["PAXFWDCABIN"] = $paxfwdcabin;
$response["PAXMIDCABIN"] = $paxmidcabin;
$response["PAXAFTCABIN"] = $paxaftcabin;
$response["FORWARDHOLD1"] = $forwardhold1;
$response["FORWARDHOLD2"] = $forwardhold2;
$response["AFTHOLD3"] = $afthold3;
$response["CHILDADJUSTMENTS"] = $childadjustments;
}
echo json_encode($response);
?>
看起来像这样：
@Scheduled(fixedDelay = DELAY_SECONDS)
private void processJobQueue() {
BlockingQueue<ReportDeliverable> jobQueue = JobQueueFactory.getJobQueueInstance();
while (!jobQueue.isEmpty()) {
//do stuff
if (rCount == 0) {
status = send(reportDeliverable);
if (status == TransferStatus.FAILURE) {
populateQueue(reportDeliverable);
}
if (status == TransferStatus.SUCCESS) { //write the metadata to database
int i = dbMetadataWriter.writeMetadata(reportDeliverable);
}
} else if (rCount == -1) {
populateQueue(reportDeliverable);
} else
logger.info("Record exists in MetaData for {}. Ignoring the File transfer....", reportDeliverable.getFilePath());
}
}
在某些情况下，当将插入数据写入数据库时，我得到数据库的表空间问题，此时我认为关闭spring启动应用程序直到表空间问题得到解决是明智的。
处理这些罕见案件的正确方法是什么？我可以使用什么技术来优雅地关闭spring启动应用程序，如何在上面的代码中执行此操作？
我的入口点类，我在处理之前最初验证所有数据库连接等，具有以下内容......
DBMetadataWriter答案 0 :(得分：0)
你在SpringApplication类上有exit（）方法，它可以用来优雅地退出Spring启动应用程序。
它需要2个参数：

代码示例：
@Autowired
public void shutDown(ExecutorServiceExitCodeGenerator exitCodeGenerator) {
SpringApplication.exit(applicationContext, exitCodeGenerator);
}
当您获得No Table space
的异常时调用此方法
