中提到的getGeneratedKeys 误导了,都以为,只要是表格里支持的,就不用自动建立表了,而只需要加上sqlDialect方言。其实不是,不管支持与否都要手动创建表。(当然你可以自己写一个java bean自动运行脚本来创建)。
还有看了很多网上的文章,经常出现 sqlDialect 这个配置节点。
我从logback 0.9.8开始测试的,对于Mysql,都不需要配置这个节点,oracle也不需要。
这一步,大家只需要在mysql中运行下面的脚本:
# Logback: the reliable, generic, fast and flexible logging framework. # Copyright (C) 1999-2010, QOS.ch. All rights reserved. # # See http://logback.qos.ch/license.html for the applicable licensing # conditions. # This SQL script creates the required tables by ch.qos.logback.classic.db.DBAppender. # # It is intended for MySQL databases. It has been tested on MySQL 5.1.37 # on Linux use tumorpredict; 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;第三必要条件:正确的配置。
这里给出一个用c3p0连接池管理的logback配置:
<appender name="db-classic-mysql" class="ch.qos.logback.classic.db.DBAppender"> <connectionSource class="ch.qos.logback.core.db.DataSourceConnectionSource"> <dataSource class="com.mchange.v2.c3p0.ComboPooledDataSource"> <driverClass>com.mysql.jdbc.Driver</driverClass> <jdbcUrl>jdbc:mysql://{$server ip}:3306/{$dbname}</jdbcUrl> <user>{$user}</user> <password>{$password}</password> </dataSource> </connectionSource> </appender>缺一不可。

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.

When selecting MySQL's BLOB and TEXT data types, BLOB is suitable for storing binary data, and TEXT is suitable for storing text data. 1) BLOB is suitable for binary data such as pictures and audio, 2) TEXT is suitable for text data such as articles and comments. When choosing, data properties and performance optimization must be considered.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
