EclipseLink MySQLSyntaxErrorException 找不到错误
EclipseLink MySQLSyntaxErrorException can't find the error
我有一个代码 运行 是这样的：
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();
但是当我尝试 运行 时，它给了我这样的错误：

我试图找出错误所在，但直到现在才弄明白。我什至试图在不放入任何东西的情况下实例化 S3Log 对象，但它仍然给出了同样的错误。
这是我的 S3Log 对象：
@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 requestId;
private String operation;
private String key;
private String requestUri;
private int httpStatus;

问题
MySQL 在这里提示您问题出在哪里：
Error Code: 1064
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near
'KEY, OBJECTSIZE, OPERATION, REFERRER, REMOTEIPADDRESS, REQUESTID, REQUESTURI, RE' at line 1
KEY 是 MySQL 中的保留字。并且保留字不能用作标识符（例如table名称，列名称）
要使用保留字作为标识符（或使用包含无效字符的字符串，例如 space），可以通过将标识符括在反引号字符中对其进行转义。
例如：
INSERT INTO `mytable` (`mycol`, `key`, ...
^ ^ ^ ^ ^ ^
修复
解决此问题的一种快速方法是在源代码中添加 JPA 2.0 指令，以覆盖默认列名，指定用反引号括起来的列名，如下所示：
private String operation;
@Column(name="`key`")
private String key;
private String requestUri;
将列名更改为保留字以外的名称是另一种（首选）选择。
有些人会（正确地）争辩说这是 MySQL 特定的修复。 （MySQL 使用单反引号，SQL 服务器使用方括号来转义标识符，Oracle 使用双引号等）所以这个“修复”与数据库的可移植性背道而驰。
JPA 配置中应该有一些通用设置，有效地表示“转义所有标识符”，这不是特定于数据库的。
我有一个代码 运行 是这样的：
S3Logs s3Logs = new S3Logs();
