我有一個運行這樣的代碼：的EclipseLink MySQLSyntaxErrorException找不到錯誤

S3Logs s3Logs = new S3Logs(); 
          s3Logs.setBucketOwner(a.getBucketOwner()); 
          s3Logs.setBucket(a.getBucket()); 
          s3Logs.setTime(a.getTime().toString()); 
          s3Logs.setRemoteIpAddress(a.getRemoteIpAddress()); 
          s3Logs.setRequester(a.getRequester()); 
          s3Logs.setRequestId(a.getRequestId()); 
          s3Logs.setOperation(a.getOperation()); 
          s3Logs.setKey(a.getKey()); 
          s3Logs.setRequestUri(a.getRequestUri()); 
          s3Logs.setHttpStatus(a.getHttpStatus()); 
          s3Logs.setErrorCode(a.getErrorCode()); 
          s3Logs.setBytesSent(a.getBytesSent()); 
          s3Logs.setObjectSize(a.getObjectSize()); 
          s3Logs.setTotalTime(a.getTotalTime()); 
          s3Logs.setTurnAroundTime(a.getTurnAroundTime()); 
          if(a.getReferrer() == "-"){ 
           s3Logs.setReferrer(null); 
          }else{ 
          s3Logs.setReferrer(a.getReferrer());} 
          if(a.getUserAgent().contains(",")){ 
           String s = a.getUserAgent().replace(",", ""); 
           s3Logs.setUserAgent(s); 
          }else{ 
           s3Logs.setUserAgent(a.getUserAgent()); 
          } 

          s3Logs.setVersionId(a.getVersionId()); 
          LogsDAO.em.persist(s3Logs); 
          LogsDAO.em.getTransaction().commit();

但是，當我試圖運行，它給了我的錯誤，像這樣：

我試着找出錯誤，但直到現在才知道。我甚至試圖實例化S3Log對象而不放入任何東西，但它仍然給出了相同的錯誤。

這裏是我的S3Log對象：

@Entity 
public class S3Logs { 

    public S3Logs() { 

    } 

    @Id 
    @GeneratedValue(strategy = GenerationType.SEQUENCE) 
    public long id; 

    private String bucketOwner; 
    private String bucket; 
    private String time; 
    private String remoteIpAddress; 
    private String requester; 
    private String requestId; 
    private String operation; 
    private String key; 
    private String requestUri; 
    private int httpStatus; 
    private String errorCode; 
    private long bytesSent; 
    private long objectSize; 
    private long totalTime; 
    private long turnAroundTime; 
    private String referrer; 
    private String userAgent; 
    private String versionId; 
}

密鑰是保留字。在查詢時用反引號將其撤銷，最好儘量避免在保留的SQL關鍵字等數據庫中命名錶/列。 –

或使用JPA提供程序來爲您做到這一點，所以您不必妥協...... –

的問題

MySQL是給你一個有關問題的所在，這裏提示：

錯誤代碼：1064

您的SQL語法有錯誤;檢查對應於你的MySQL服務器版本的手冊正確的語法附近

'KEY, OBJECTSIZE, OPERATION, REFERRER, REMOTEIPADDRESS, REQUESTID, REQUESTURI, RE' at line 1

KEY使用是一個保留字在MySQL。並且保留字不能用作標識符（例如表名，列名）

要使用保留字作爲標識符（或使用包含無效字符（如空格）的字符串），標識符可以通過將它包含在反引號字符中來逃脫。

例如：

INSERT INTO `mytable` (`mycol`, `key`, ... 
      ^ ^^ ^^ ^

THE FIX

一種快速的方法來解決這一問題是增加一個JPA 2.0指令中的源極，覆蓋默認的列名，指定反引號中包含的列名如下所示：

private String operation; 
@Column(name="`key`") 
private String key; 
private String requestUri;

將列名更改爲保留字以外的內容將是另一個（首選）選項。

有些人會（正確地）爭辯說這是一個MySQL特定的修補程序。 （MySQL使用單向反引號，SQL Server使用方括號來轉義標識符，Oracle使用雙引號等等）。所以這個「修復」在數據庫可移植性方面飛速發展。

在JPA配置中應該有一些常規設置，它有效地表示「轉義所有標識符」，這不會是數據庫特定的。

JPA規範定義了使用@Column（name =「\」key \「」）（JPA 2。0，第2.13節），以按名稱使用分隔符。這將轉換爲數據庫特定的表示法，並且使用變通辦法可能會導致本機查詢出現問題，其中返回的列名可能與列定義不匹配。 – Chris
