Question

我有一张表ReservationDataHash。相同的实体是：

ReservationDataHash.java：

set_error_handler('fatalErrorHandler', [E_ERROR]);

function fatalErrorHandler($errno, $errstr, $errfile, $errline){
     throw new \Exception($errstr." @$errfile:$errline", $errno);
}

/* ... */ 

try{
     // Likely defective code...
}catch(\Exception $e) {
     $cronlocklog->add("cron job failed with error: ".$e->getMessage());
} finally {
     flock($cronlockfd, LOCK_UN);
}

存储库是，

GuestHashCodeRepository.java ：

import java.io.Serializable;
import java.util.Date;
import java.util.UUID;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

import org.hibernate.annotations.GenericGenerator;
import org.hibernate.annotations.Type;

/**

@Entity
@Table(name = "reservationdatahash", schema = "public")
public class ReservationDataHash implements Serializable{

/**

private static final long serialVersionUID = 1L;

/** The entity hash id. */
@Id
@GenericGenerator(name = "uuid", strategy = "uuid2")
@GeneratedValue(generator = "uuid")
@Column(name = "reservationdatahashid", unique = true, nullable = false)

public UUID getHashId() {
    return hashId;
}

public void setHashId(UUID hashId) {
    this.hashId = hashId;
}

public String getUniqueSourceId() {
    return uniqueSourceId;
}

public void setUniqueSourceId(String uniqueSourceId) {
    this.uniqueSourceId = uniqueSourceId;
}

/**

public final String getDxpId() {
    return dxpId;
}

/**

public final void setDxpId(final String dxpId) {
    this.dxpId = dxpId;
}

/**

 *

 */
public final String getHashCode() {
    return hashCode;
}

/**
 * Sets the hash code.
 *
 * @param hashCode
 *            the new hash code
 */
public final void setHashCode(final String hashCode) {
    this.hashCode = hashCode;
}

/**
 * Gets the failed hash code.
 *
 * @return the failed hash code
 */
public final String getFailedHashCode() {
    return failedHashCode;
}

/**
 * Sets the failed hash code.
 *
 * @param failedHashCode
 *            the new failed hash code
 */
public final void setFailedHashCode(final String failedHashCode) {
    this.failedHashCode = failedHashCode;
}

/**
 * Gets the retry attempt.
 *
 * @return the retry attempt
 */
public final Integer getRetryAttempt() {
    return retryAttempt;
}

/**
 * Sets the retry attempt.
 *
 * @param retryAttempt
 *            the new retry attempt
 */
public final void setRetryAttempt(final Integer retryAttempt) {
    this.retryAttempt = retryAttempt;
}

/**

 */
public final Date getLastModifiedDate() {
    return lastModifiedDate;
}

/**

 *            the new last modified date
 */
public final void setLastModifiedDate(final Date lastModifiedDate) {
    this.lastModifiedDate = lastModifiedDate;
}

}

我经常在我的Processor（）中调用方法import java.util.UUID; import javax.transaction.Transactional; import org.springframework.data.jpa.repository.JpaRepository; import org.springframework.data.jpa.repository.Query; import org.springframework.data.repository.query.Param; import org.springframework.data.rest.core.annotation.RepositoryRestResource; import org.springframework.stereotype.Repository; /** * The Interface EntityHashRepository. */ @Repository @Transactional public interface GuestHashCodeRepository extends JpaRepository<ReservationDataHash, UUID> { @Query("select r from ReservationDataHash r " + "where (r.uniqueSourceId = :uniqueSourceId) ") ReservationDataHash findByUniqueSourceId( @Param("uniqueSourceId") String uniqueSourceId ); }，

findByUniqueSourceId()

一段时间后，当批处理作业在环境中运行时，我开始在服务中看到此方法中传递的所有数据的以下错误，

public ReservationDataHash getReservationGuestHashCodeByUniqueSourceId(String uniqueSourceID) {

    return guestHashCodeRepo.findByUniqueSourceId(uniqueSourceID);
}

当我为本地连接到同一数据库的特定数据测试相同内容时，我不会遇到任何错误。

请帮助我，因为我无法理解这个问题。

看起来你的堆栈跟踪很低，你的交易中止了 - 我猜你的交易会因为死锁而被取消？

其他人可能只是锁定了您要读取的行，最终导致死锁。

也许你可以通过不使用交易来逃脱它？（假设这些ID不会改变）否则，您可能需要在较高级别重新启动事务。
