logback日志配置.docx

logback日志配置一、简介：logback是一个可靠、通用、快速而又灵活的Java日志框架。 声称要取代log4j.Logback is intended as a successor to the popular log4j projeclogback当前分成三个模块：logback-core，logback- classic和logback-access。logback-core是其它两个模块的基础模块。logback-classic是log4j的一个改良版本。logback-classic完整实现SLF4J API使你可以很方便地更换成其它日志系统如log4j或JDK14 Logging。 logback-access访问模块与Servlet容器集成提供通过Http来访问日志的功能。所以，导入的架包必须有以下：若实现日志保存到mysql数据库，还需要：以日志导入到mysql数据库为例（maven项目）：pom.xml配置：org.slf4jslf4j-api$slf4j.versioncompilech.qos.logbacklogback-classic$logback.versionruntimemysqlmysql-connector-java5.1.25commons-dbcpcommons-dbcp1.4在mysql中创建3张表（一定要手动建立，logback不会自动生成）：语句如下：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;新建logBack.xml文件并进行配置如下： UTF-8 %dyyyy-MM-dd HH:mm:ss.SSS %thread %-5level %logger50 - %msg%n UTF-8 $LOG_HOME/myProject.log.%dyyyy-MM-dd.log 30 %dyyyy-MM-dd HH:mm:ss.SSS %thread %-5level %logger50 - %msg%n 10MB com.mysql.jdbc.Driver jdbc:mysql:/:3306/数据库 用户名 密码 使用与log4j相同：private static final Logger
