Incorrect encoding when initializing database with DataSourceInitializer in Spring Framework

Question

I am using Spring Framework 4 and Hibernate 4 together with MySQL database. For initializing database with data I use initialization script configured in hibernate.xml file.

Initialization of database goes alright, but in database appears ? instead of characters with diacritics. For example instead of Česko I see ?esko.

Any ideas?

database.sql

INSERT INTO COUNTRY (ID, NAME) VALUES (1, 'Slovensko'), (2, 'Česko'), (3, 'Poľsko'), (4, 'Maďarsko');

COUNTRY table created by Hibernate

CREATE TABLE `country` (
  `ID` bigint(20) NOT NULL AUTO_INCREMENT,
  `NAME` varchar(100) NOT NULL,
  PRIMARY KEY (`ID`),
  UNIQUE KEY `UK_l7qlysdc1xbo69vsmueersr2k` (`NAME`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8

database.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/BPM?UseUnicode=true;characterEncoding=utf8
jdbc.username=root
jdbc.password=root

Answer 1

I managed to solve the issue. The problem was in connection URL, it should be:

jdbc.url=jdbc:mysql://localhost:3306/BPM?characterEncoding=UTF-8
