Also, make sure the MySQL database is UTF-8 aware. For instance, you can create a UTF-8-aware MySQL database like this:
~~~create-database.sql~~~

create database hibernatetest
DEFAULT CHARACTER SET utf8
DEFAULT COLLATE utf8_general_ci;

~~~create-database.sql~~~

you just need to encode the ampersand with & on the persistence xml.

…?autoReconnect=true&useUnicode=true&characterEncoding=UTF-8

after much struggling this is what works for me:

1. yes, you can modify the JDBC URL, but it’s a little clunky and requires just the right string, e.g.:
jdbc:mysql://localhost/db?useUnicode=true&characterEncoding=utf8 (assuming this is embedded in XML)

2. a litter clearer, but not well documented at all, are these additional connection settings in the hibernate cfg XML:

utf8
true

NOTE: both charSet and useUnicode are required for latest version of hibernate and mysql. it took me quite a while to figure this out.

again, either 1. or 2. will work, but my preference is for #2.

i wonder when the world will finally understand and make encoding easier…..

frustrated, but struggled and *finally* got it right.

In Hibernate 3.0 with MySQL 4 and mysql-connector 3.0.8, UTF-8 is not working…
core mysql APIs are fetching and inserting utf8 characters correctly, but Hibernate session is not selecting or inserting special characters. I have tried it with Hibernate 3.0 + Mysql 5 + mysql-connector 5.0.8, working fine… but not with above config

Please help me, how can I insert special characters (UTF-8) using this config : Hibernate 3.0 + Mysql 4.0.1 + mysql-connector 3.0.8

my hibernat-cfg.xml file contain:

true
UTF-8

In JSPs :

in HTML :

Even I am using :
request.setCharacterEncoding(“UTF-8″);
in Filter.

I will highly appreciate…

Took me a little while to work out that you need to escape the ‘&’ with & in the hibernate.cfg.xml

useUnicode=true&characterEncoding=UTF-8
