最近要做毕业设计,以前用的数据库是oracle,基本上没出现过中文乱码的问题。可是毕业设计人在外地,带的笔记本比较垃圾,oracle根本带不起。一个eclipse加上一个火狐cpu就已经跑到90%了。所以最后决定用mysql数据库。前台用的是jsp,使用的编码格式是utf-8。
不过mysql的中文乱码让我纠结了许久。经过一番查询,最终解决了。
一:查看编程环境是否为utf-8
方法:右键项目名称-属性 找到文本文件编码 选择utf-8.
二:设置jsp页面的编码格式:
方法:contentType="text/html; charset=utf-8"
meta http-equiv="Content-Type" content="text/html; charset=utf-8"
三:设置request和response的编码格式:
方法:response.setContentType("text/html ;charset=utf-8");
request.setCharacterEncoding("utf-8");
四:编写过滤器
五:连接数据库的方式改为:jdbc:mysql://localhost/databasename?useUnicode=true&characterEncoding=UTF-8
经过以上5步,如果问题依然没有解决的话,则有可能是出现在mysql服务器上。
数据库方面
一:首先查看数据库字符集设置
方法:set character_set_client=utf8;
用这个方法可以看到几个字符集。
然后用以下命令修改
set character_set_client=utf8;
set character_set_connection=utf8;
set character_set_database=utf8;
set character_set_results=utf8;
set character_set_server=utf8;
当然也可以在mysql的安装目录下,一般在c盘中的 my.ini下修改凡是看到字符集有关的都修改成utf8
做到这步,基本上从数据库中取出的数据都是中文,但是还是有可能会出现问题,比如在用dos打开的时候,中文依然显示为乱码,而且不能在dos环境下用sql语句插入中文字符。
这时,要把set character_set_results=utf8; 改为 set character_set_results=gbk;
set character_set_client=utf8; 改为 set character_set_client=gbk;
这样,基本就能解决了。

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

Apache connects to a database requires the following steps: Install the database driver. Configure the web.xml file to create a connection pool. Create a JDBC data source and specify the connection settings. Use the JDBC API to access the database from Java code, including getting connections, creating statements, binding parameters, executing queries or updates, and processing results.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The process of starting MySQL in Docker consists of the following steps: Pull the MySQL image to create and start the container, set the root user password, and map the port verification connection Create the database and the user grants all permissions to the database

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

I encountered a tricky problem when developing a small application: the need to quickly integrate a lightweight database operation library. After trying multiple libraries, I found that they either have too much functionality or are not very compatible. Eventually, I found minii/db, a simplified version based on Yii2 that solved my problem perfectly.
