我正在使用hibernate search 5.5.4，同时向数据库添加新记录，发生此异常并且数据已成功插入数据库但未创建索引
发生异常org.apache.lucene.store.LockObtainFailedException：由另一个程序持有的锁：var / lucene / indexes / com.org.Recipe / write.lock

Ya解决了，问题是当我将session.save()更改为session.persist()时我试图将数据保持为import java.util.Scanner;
public class Programming {
/*
* get the number of matching digits between the guess and the
* answer, ignoring repeated matches
*/
public static int numberDigitsMatch(String guess, String answer) {
int numberMatch = 0;
int currentIndex = 0;
int matchingIndex;
while (currentIndex < guess.length()) {
// check if the current digit of the guess is in the answer
matchingIndex = answer.indexOf(guess.charAt(currentIndex));
if (matchingIndex < 0) {
currentIndex++;
}
else {
currentIndex++;
numberMatch++;
// remove the no longer relevant character from the answer
answer = answer.substring(0, matchingIndex) +
answer.substring(matchingIndex + 1);
}
}
return numberMatch;
}
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
// generate the winning number
int lotteryNumber = (int) (Math.random() * 10000);
String lotteryString = "" + lotteryNumber;
System.out.println("The lottery number is " + lotteryString);
// Prompt the user to enter a guess
System.out.print("Enter your lottery pick (four digits): ");
// get the user's guess
int guessNumber = in.nextInt();
String guessString = "" + guessNumber;
// NOTE: these guessDigit numbers are not necessary. I am leaving
// them here so you can see how to pick out individual digits
int guessDigit1 = guessNumber % 10;
int guessDigit2 = (guessNumber / 10) % 10;
int guessDigit3 = (guessNumber / 100) % 10;
int guessDigit4 = (guessNumber / 1000) % 10;
int lotteryDigit1 = lotteryNumber % 10;
int lotteryDigit2 = (lotteryNumber / 10) % 10;
int lotteryDigit3 = (lotteryNumber / 100) % 10;
int lotteryDigit4 = (lotteryNumber / 1000) % 10;
System.out.println("The lottery number is " + lotteryString);
int numMatchingDigits = numberDigitsMatch(guessString, lotteryString);
if (guessNumber == lotteryNumber) {
System.out.println("Exact match: you win $10,000");
}
else if (4 == numMatchingDigits) {
System.out.println("Match all digits: you win $5,000");
}
else if (3 == numMatchingDigits) {
System.out.println("Match three digits: you win $2,000");
}
else if (2 == numMatchingDigits) {
System.out.println("Match two digits: you win $500");
}
else if (1 == numMatchingDigits) {
System.out.println("Match two digit: you win $500");
}
else {
System.out.println("Sorry, no match");
}
}
}
问题消失了，索引值只能在持久，更新，删除等时更新。

字面意思是错误所说的：还有另一个进程仍在运行，它“拥有”索引上的锁。
这很可能是Hibernate Search的另一个实例;例如，如果您之前启动了应用程序，并且没有将其关闭，就会发生这种情况。
