JDBC 是 Java 应用程序中访问关系型数据库的标准 API,但并非唯一选择。相比其他选项,JDBC 标准化程度高,但开销较高,而其他选项针对特定数据库优化,性能可能更高。可移植性方面,JDBC 跨不同数据库可移植性高,但其他选项仅限于支持的数据库。最后,JDBC 学习曲线较陡,而其他选项的学习曲线因选项而异。

Java 数据库连接与 JDBC 的比较

Java 数据库连接 (JDBC) 是一种访问数据库的标准 API,用于在 Java 应用程序中建立与关系型数据库的连接。虽然 JDBC 是最流行的 Java 数据库连接,但它并不是唯一的选择。本文将介绍 Java 数据库连接与 JDBC 的主要区别,并提供一个实战案例来说明这些区别。

区别

特征 JDBC 其他选项
标准化 标准 API 依赖于特定数据库
连接器 由 JDBC 驱动程序提供 由数据库提供
性能 由于标准化,开销较高 由于针对特定数据库进行优化,可能性能更高
可移植性 跨不同数据库高度可移植 仅限于支持的数据库
学习曲线 学习曲线较陡 学习曲线因选项而异

实战案例

考虑一个需要访问 MySQL 数据库的 Java 应用程序。以下是使用 JDBC 和另一种数据库连接选项(例如 MySQL Connector/J)实现此功能的代码:

使用 JDBC:

// 加载 JDBC 驱动程序
Class.forName("com.mysql.jdbc.Driver");

// 建立数据库连接
Connection connection = DriverManager.getConnection("jdbc:mysql://localhost/mydb", "root", "password");

使用 MySQL Connector/J:

// 加载 MySQL Connector/J 驱动程序
Class.forName("com.mysql.cj.jdbc.Driver");

// 建立数据库连接
Connection connection = DriverManager.getConnection("jdbc:mysql://localhost/mydb?user=root&password=password");

结论

虽然 JDBC 是 Java 数据库连接的标准选择,但它并非万能的。在某些情况下,使用特定数据库提供的替代选项可能更合适。在做出决策之前,考虑性能、可移植性和学习曲线的权衡因素至关重要。

Java implementation "write once, run everywhere" is compiled into bytecode and run on a Java virtual machine (JVM). 1) Write Java code and compile it into bytecode. 2) Bytecode runs on any platform with JVM installed. 3) Use Java native interface (JNI) to handle platform-specific functions. Despite challenges such as JVM consistency and the use of platform-specific libraries, WORA greatly improves development efficiency and deployment flexibility.

mPDF

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),
