mySql---logback日志写入数据库(mysql)配置

如题建议将日志级别设置为ERROR。这样可以避免存储过多的数据到数据中。

1 logback 配置文件（如下）

<?xml version="1.0" encoding="UTF-8" ?>

<configuration scan="true">

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">

        <encoder>

            <pattern>%d{HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n

            </pattern>

        </encoder>

    </appender>

    <!-- 将日志写入日志文件 -->

    <appender name="FILE" class="ch.qos.logback.core.FileAppender">

        <file>${catalina.base}/logs/cnsurvey-order-ws.log</file>

        <append>true</append><!-- 日志追加 -->

        <encoder>

            <pattern>%d{HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n

            </pattern>

        </encoder>

    </appender>

    <!-- 将日志写入数据库 -->

    <appender name="DB-CLASSIC-MYSQL-POOL" class="ch.qos.logback.classic.db.DBAppender">

        <connectionSource class="ch.qos.logback.core.db.DataSourceConnectionSource">

            <dataSource class="org.apache.commons.dbcp.BasicDataSource">

                <driverClassName>com.mysql.jdbc.Driver</driverClassName>

                <url>jdbc:mysql://localhost:3306/cbs_ifs_order?characterEncoding=UTF-8</url>

                <username>root</username>

                <password>root</password>

            </dataSource>

        </connectionSource>

    </appender>

    <root level="ERROR">

        <appender-ref ref="STDOUT" />

        <appender-ref ref="FILE" />

        <appender-ref ref="DB-CLASSIC-MYSQL-POOL" />

    </root>

</configuration>

如果想让日志写入到数据库中，必须手动添加额外的数据库表（mysql 测试）。如果mysql 中没有指定表，则不会写数据。

表结构如下

BEGIN;

DROP TABLE IF EXISTS logging_event_property;

DROP TABLE IF EXISTS logging_event_exception;

DROP TABLE IF EXISTS logging_event;

COMMIT;

BEGIN;

CREATE TABLE logging_event

  (

    timestmp         BIGINT NOT NULL,

    formatted_message  TEXT NOT NULL,

    logger_name       VARCHAR(254) NOT NULL,

    level_string      VARCHAR(254) NOT NULL,

    thread_name       VARCHAR(254),

    reference_flag    SMALLINT,

    arg0              VARCHAR(254),

    arg1              VARCHAR(254),

    arg2              VARCHAR(254),

    arg3              VARCHAR(254),

    caller_filename   VARCHAR(254) NOT NULL,

    caller_class      VARCHAR(254) NOT NULL,

    caller_method     VARCHAR(254) NOT NULL,

    caller_line       CHAR(4) NOT NULL,

    event_id          BIGINT NOT NULL AUTO_INCREMENT PRIMARY KEY

  );

COMMIT;

BEGIN;

CREATE TABLE logging_event_property

  (

    event_id       BIGINT NOT NULL,

    mapped_key        VARCHAR(254) NOT NULL,

    mapped_value      TEXT,

    PRIMARY KEY(event_id, mapped_key),

    FOREIGN KEY (event_id) REFERENCES logging_event(event_id)

  );

COMMIT;

BEGIN;

CREATE TABLE logging_event_exception

  (

    event_id         BIGINT NOT NULL,

    i                SMALLINT NOT NULL,

    trace_line       VARCHAR(254) NOT NULL,

    PRIMARY KEY(event_id, i),

    FOREIGN KEY (event_id) REFERENCES logging_event(event_id)

  );

COMMIT;
