重装数据库之后,项目出现中文乱码
乱码问题的出现,根本原因就是编码没统一,既然重装数据库之前,项目是没有中文乱码的,所以问题肯定是出现在数据库的编码上。 运行mysql之后,输入以下命令 show variables like 'character%'; 笔者的查询结果如下: 其中,character_set_client 客户端编码
乱码问题的出现,根本原因就是编码没统一,既然重装数据库之前,项目是没有中文乱码的,所以问题肯定是出现在数据库的编码上。
运行mysql之后,输入以下命令
show variables like 'character%';
笔者的查询结果如下:
其中,character_set_client 客户端编码方式;
character_set_connection 建立连接使用的编码;
character_set_database 数据库的编码;
character_set_results 结果集的编码;
character_set_server 数据库服务器的编码;
只要保证以上四个采用的编码方式一样,就不会出现乱码问题。由此可见笔者的数据库果然是会出现编码问题的。。解决方法也很简单,在每个项目的数据库连接配置文件中加上这个就可以了
jdbc:mysql://localhost:3306/databasename?useUnicode=true&characterEncoding=utf-8
或者
jdbc:mysql://localhost:3306/databasename?useUnicode=true&characterEncoding=utf-8
可以根据不同的XML解析工具来选择其中一个来用。

Fermat's last theorem, about to be conquered by AI? And the most meaningful part of the whole thing is that Fermat’s Last Theorem, which AI is about to solve, is precisely to prove that AI is useless. Once upon a time, mathematics belonged to the realm of pure human intelligence; now, this territory is being deciphered and trampled by advanced algorithms. Image Fermat's Last Theorem is a "notorious" puzzle that has puzzled mathematicians for centuries. It was proven in 1993, and now mathematicians have a big plan: to recreate the proof using computers. They hope that any logical errors in this version of the proof can be checked by a computer.

Tips for solving Chinese garbled characters written by PHP into txt files. With the rapid development of the Internet, PHP, as a widely used programming language, is used by more and more developers. In PHP development, it is often necessary to read and write text files, including txt files that write Chinese content. However, due to encoding format problems, sometimes the written Chinese will appear garbled. This article will introduce some techniques to solve the problem of Chinese garbled characters written into txt files by PHP, and provide specific code examples. Problem analysis in PHP, text

Go language is an efficient, concise and easy-to-learn programming language. It is favored by developers because of its advantages in concurrent programming and network programming. In actual development, database operations are an indispensable part. This article will introduce how to use Go language to implement database addition, deletion, modification and query operations. In Go language, we usually use third-party libraries to operate databases, such as commonly used sql packages, gorm, etc. Here we take the sql package as an example to introduce how to implement the addition, deletion, modification and query operations of the database. Assume we are using a MySQL database.

Hibernate polymorphic mapping can map inherited classes to the database and provides the following mapping types: joined-subclass: Create a separate table for the subclass, including all columns of the parent class. table-per-class: Create a separate table for subclasses, containing only subclass-specific columns. union-subclass: similar to joined-subclass, but the parent class table unions all subclass columns.

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

HTML cannot read the database directly, but it can be achieved through JavaScript and AJAX. The steps include establishing a database connection, sending a query, processing the response, and updating the page. This article provides a practical example of using JavaScript, AJAX and PHP to read data from a MySQL database, showing how to dynamically display query results in an HTML page. This example uses XMLHttpRequest to establish a database connection, send a query and process the response, thereby filling data into page elements and realizing the function of HTML reading the database.

To handle database connection errors in PHP, you can use the following steps: Use mysqli_connect_errno() to obtain the error code. Use mysqli_connect_error() to get the error message. By capturing and logging these error messages, database connection issues can be easily identified and resolved, ensuring the smooth running of your application.

How to use MySQLi to establish a database connection in PHP: Include MySQLi extension (require_once) Create connection function (functionconnect_to_db) Call connection function ($conn=connect_to_db()) Execute query ($result=$conn->query()) Close connection ( $conn->close())
