使用logback-1.0.13.jar.

用于创建所需表的 DDL 脚本DBAppender位于该 JAR 内：

logback-1.0.13/logback-access/src/main/java/ch/qos/logback/ access /db/script/mysql.sql

这个文件的内容是：

# INNODB tables.


BEGIN;
DROP TABLE IF EXISTS access_event_header;
DROP TABLE IF EXISTS access_event;
COMMIT;

BEGIN;
CREATE TABLE ACCESS_EVENT 
(
timestmp          BIGINT NOT NULL,
requestURI        VARCHAR(254),
requestURL        VARCHAR(254),
remoteHost        VARCHAR(254),
remoteUser        VARCHAR(254),
remoteAddr        VARCHAR(254),
protocol          VARCHAR(254),
method            VARCHAR(254),
serverName        VARCHAR(254),
postContent       VARCHAR(254),
event_id          BIGINT NOT NULL AUTO_INCREMENT PRIMARY KEY
);
COMMIT;

BEGIN;
CREATE TABLE access_event_header
(
event_id          BIGINT NOT NULL,
header_key        VARCHAR(254) NOT NULL,
header_value      VARCHAR(1024),
PRIMARY KEY(event_id, header_key),
FOREIGN KEY (event_id) REFERENCES access_event(event_id)
);
COMMIT;

我在我的 MySQL 服务器上运行了这个脚本，它成功执行，创建了 access_event表access_event_header。

我的logback-test.xml配置：

<configuration debug="true" scan="true" scanPeriod="5 minutes">
    <appender name="logManager-dbAppender" class="ch.qos.logback.**classic**.db.DBAppender">
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>INFO</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>NEUTRAL</onMismatch>
        </filter>
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>WARN</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>NEUTRAL</onMismatch>
        </filter>
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>ERROR</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>

        <connectionSource class="ch.qos.logback.core.db.DriverManagerConnectionSource">
            <driverClass>com.mysql.jdbc.Driver</driverClass>
            <url>jdbc:mysql://mysql.server.example.com:3306/my_db</url>
            <user>my_user</user>
            <password>my_password</password>
        </connectionSource>
    </appender>

    <root level="ALL">
        <appender-ref ref="logManager-dbAppender" />
    </root>
</configuration>

我使用 Logback 的 Java 驱动程序：

public class LogbackTester {
    private Logger logger = LoggerFactory.getLogger(LogbackTester.class);

    public static void main(String[] args) {
        LogbackTester tester = new LogbackTester();
        tester.run();
    }

    private void run() {
        logger.debug("Logging a DEBUG message.");
        logger.trace("Logging a TRACE message.");
        logger.info("Logging an INFO message.");
        logger.warn("Logging a WARN message.");
        logger.error("Logging an ERROR message.");
    }
}

当那个 Java 执行时，我得到这个控制台输出：

22:09:55,266 |-ERROR in ch.qos.logback.classic.db.DBAppender[logManager-dbAppender] - problem appending event com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'my_db.logging_event' doesn't exist

为什么要找logging_event桌子？1.0.13 是否附带了错误的 DDL 脚本？如果是这样，与 1.0.13 一起使用的正确 DDL 是什么DBAppender？

您将logback-access与logback-classic混淆了。在“logback-1.0.13/logback- classic /src/main/java/...”下搜索 mysql.sql 并使用该文件创建表。

Logback-access 用于与 Jetty 或 Tomcat 等 Web 服务器一起记录 (HTTP) 访问事件。原生实现 SLF4J API 的 Logback-classic 用于开发人员日志记录。
