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;
