使用hibernate自動建立Mysql表失敗緣由

1.使用 schemaExport(hibernate5.2.3)建立Mysql表 sql

@Test
    public void testSchemaExport() {

        ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().configure().build();
        Metadata metadata = new MetadataSources(serviceRegistry).buildMetadata();
        SchemaExport schemaExport = new SchemaExport();
        schemaExport.create(EnumSet.of(TargetType.DATABASE), metadata);

    }

2.使用上面的代碼能夠生成SQL可是建表別沒有成功;ui

Hibernate: 
    create table User (
        id integer not null,
        age integer,
        name varchar(255),
        primary key (id)
    ) type=InnoDB

把hibernate生成的SQL語句在Navicat中執行出現錯誤;spa

[Err] 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Hibernate: 
    create table User (
        id integer not null,
        age ' at line 1

3.通過查找發現是hibernate裏的dialect和Mysql的版本不匹配,SQL語句裏的type=InnoDB使用在MySQL5.0以前,5.0以後就要是使用engine=InnoDBhibernate

MySql5.0以前的配置

 <property name="dialect">org.hibernate.dialect.MySQLInnoDBDialect</property>

5.0以後須要使用

<property name="dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>

4.修改後的hibernate生成SQL語句以下,建表成功;code

Hibernate: 
    create table User (
        id integer not null,
        age integer,
        name varchar(255),
        primary key (id)
    ) ENGINE=InnoDB
