Question

我想通过log4j2 JDBCAppender将日志文件导入数据库，但是我不知道如何在数据库表中添加一列来保存指定的值，例如，您可以手动指定ID日志记录，以便以后通过ID检索记录

log4j2-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="error">
    <Appenders>
        <JDBC name="databaseAppender" tableName="wyy.logs">

           <!-- <Column name="EVENT_ID" literal="logs_event_id_pk" isUnicode="false" />-->

            <AppenderRef ref="databaseAppender"/>
            <AppenderRef ref="Console"/>
        </Root>
    </Loggers>

</Configuration>

java

@RestController
public class HelloController {
    private final static Logger logger = LoggerFactory.getLogger(HelloController.class);
    @RequestMapping(value = "/hello",method = RequestMethod.GET)
    public String sayHello(){
        logger.info("Inside HelloController creating instance"+DateFormat.getInstance().format(new Date()));
        logger.error("error");
        return "Hello,Spring boot!";
    }
}

表结构

create table logs
(
  event_id   serial not null
    constraint logs_event_id_pk
    primary key,
  event_date timestamp,
  logger     text,
  level      text,
  message    text,
  throwable  text,
  id         integer
);

将日志插入数据库时，我可以手动输入id列

如何通过log4j2 JDBCAppender在自定义列中添加指定的值
