HomeDatabaseMysql Tutorial服务器-hibernate操作mysql,模糊查询时中文查不到,数字和英文可以查到

服务器mysql远程连接hibernate

用hibernate做模糊查询,页面传递参数也处理了乱码
@Action(value="searchNameByad")
public String searchNameByad()throws Exception{
System.out.println("android发送请求获取的参数是:"+buildingname);
//解决乱码问题
String bn = new String(buildingname.getBytes("iso-8859-1"),"UTF-8");
List buildings = buildingService.getByName(bn);
在本地测试传中文参数可以查到数据,但是在上传到服务器后,传递中文参数却查不到,只能数字、英文可以查询到结果。我用本地远程连接服务器数据库,也是中文参数查不到数据。。。在服务器上的数据库里操作查询也是可以查的到。。求解
这是本地远程连接服务器数据库后的hql语句
Hibernate: select building0_.buildingid as buildingid11_, building0_.area as area11_, building0_.buildingname as building3_11_, building0_.linkman as linkman11_, building0_.linkphone as linkphone11_, building0_.email as email11_, building0_.qrcode as qrcode11_, building0_.province as province11_, building0_.city as city11_ from airquality.building building0_ where building0_.buildingname like '%广%'

Common security vulnerabilities in MySQL include SQL injection, weak passwords, improper permission configuration, and unupdated software. 1. SQL injection can be prevented by using preprocessing statements. 2. Weak passwords can be avoided by forcibly using strong password strategies. 3. Improper permission configuration can be resolved through regular review and adjustment of user permissions. 4. Unupdated software can be patched by regularly checking and updating the MySQL version.

How can you identify slow queries in MySQL?How can you identify slow queries in MySQL?Apr 26, 2025 am 12:15 AM

Identifying slow queries in MySQL can be achieved by enabling slow query logs and setting thresholds. 1. Enable slow query logs and set thresholds. 2. View and analyze slow query log files, and use tools such as mysqldumpslow or pt-query-digest for in-depth analysis. 3. Optimizing slow queries can be achieved through index optimization, query rewriting and avoiding the use of SELECT*.

How can you monitor MySQL server health and performance?How can you monitor MySQL server health and performance?Apr 26, 2025 am 12:15 AM

To monitor the health and performance of MySQL servers, you should pay attention to system health, performance metrics and query execution. 1) Monitor system health: Use top, htop or SHOWGLOBALSTATUS commands to view CPU, memory, disk I/O and network activities. 2) Track performance indicators: monitor key indicators such as query number per second, average query time and cache hit rate. 3) Ensure query execution optimization: Enable slow query logs, record and optimize queries whose execution time exceeds the set threshold.

When would you choose InnoDB over MyISAM, and vice versa?When would you choose InnoDB over MyISAM, and vice versa?Apr 25, 2025 am 12:22 AM

The situations when choosing InnoDB instead of MyISAM include: 1) transaction support, 2) high concurrency environment, 3) high data consistency; conversely, the situation when choosing MyISAM includes: 1) mainly read operations, 2) no transaction support is required. InnoDB is suitable for applications that require high data consistency and transaction processing, such as e-commerce platforms, while MyISAM is suitable for read-intensive and transaction-free applications such as blog systems.
