For some MySQL data types full column definition results in the following exception (that stops a spring boot application from starting): org.hibernate.tool.schema.spi.SchemaManagementException: Schema-validation: wrong column type encountered in column [level] in table [test_data] ; found tinyint (Types#TINYINT) ( #TINYINT) ) , but expecting tinyint unsigned default '0' (Types#INTEGER) ( #INTEGER) ) For example, for this table: CREATE TABLE `test_data` ( `id` int unsigned NOT NULL AUTO_INCREMENT, `level` tinyint unsigned DEFAULT '0', `delete_date` datetime DEFAULT '1970-01-01 00:00:00', PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; this is fine: @Column(name = "level", columnDefinition = "tinyint") private int level; but this results in the exception mentioned above: @Column(name = "level", columnDefinition = "tinyint UNSIGNED DEFAULT '0'") private int level; Same for datetime, bit and maybe others.
