The first time you run the program, the Hibernate.hbm2ddl.auto in Hibernte is set to create, allowing hibernate to help automatically build the table, but not successfully, with the following information:
You have a error in your SQL syntax; Check the manual-corresponds to your MySQL server version for the right syntax-use-near ' Type=innodb ' on line 1
I wonder why there was no such a problem before? Is it the wrong syntax for building a table statement? After contrast, it does not seem. Then read the error message carefully, looking at "MySQL Server version for the right syntax"!!
Later, the online search, found that because the TYPE=INNODB is available before 5.0, but after 5.1 is not. If we change the Type=innodb to Engine=innodb, we will not have this problem. But, I want to use Hibernate, automatically help me to build a table, how to do it. This is related to the database dialect (dialect) that we have specified.
Prior to my configuration was:
<PropKey="Hibernate.dialect">Org.hibernate.dialect.MySQLInnoDBDialect</Prop>
Now instead
<PropKey="Hibernate.dialect">Org.hibernate.dialect.MySQL5InnoDBDialect</Prop>
OK, so the problem is solved. Summary below:
Hibernate, for MySQL version5.1~5.5, are 'mysql5innodbdialect '!!
Type=innodb and Engine=innodb note points when first touch Hibernate01--mysql is built
