你这种情况不只是在Hibernate中会碰到,就是在我们现在主流的php中同样会碰到,如果你的数据库编码与页面编码不一样,就可能出现中文乱码的问题。
今天在用Hibernate向MySQL中插入数据时出现了乱码的问题,具体表现时我在插入前用utf-8打印出来中文时OK的,然后用MySQL Workbench设置成uft-8来显示从MySQL中查询出来的数据也是正确的,但是当我把代码中的数据插入之后再进行查询时查询出来的就是乱码了,不知道怎么设置,因为两头utf-8都没问题,那问题肯定时出在了中间环节,也就是connect的时候。网上到处找结果终于找到了。
我们只需要在hibernate.property或者时hibernate.cfg.xml(取决于你是怎么连接数据库的)文件中进行一下设置就OK了。
原本我的连接语句是这么写的:
代码如下 | 复制代码 |
jdbc:://localhost:3306/tablename |
然后我修改成了:
代码如下 | 复制代码 |
jdbc:mysql://localhost:3306/tablename?useUnicode=true&characterEncoding=utf8 |
发现还是不行,原来是要改成这样:
代码如下 | 复制代码 |
jdbc:mysql://localhost:3306/tablename?useUnicode=true&characterEncoding=utf8 ]]> |

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

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.
