mysql生成uuid的操作
hibernate中这样配置主键生成后，mysql中并未指定主键生成机制，
使用navicat通过sql语句insert数据时仍需指定id，
java代码
insert into g_distinct values ( replace(uuid(),'-',''),'110101','东城区','110100');
java代码
@id
@genericgenerator(name = generator, strategy = uuid.hex)
@generatedvalue(generator = generator)
@column(name = location_id, length = 40)
public string getlocationid() {
return locationid;
}
