调用wuid生成id后，会自动关闭数据库连接，导致后续数据库操作无法继续执行
package tools
import (

"database/sql"
"github.com/astaxie/beego/orm"
"github.com/edwingeng/wuid/mysql"
_"github.com/go-sql-driver/mysql"

)

var newDB = func() (*sql.DB,bool,error){
db,_ := orm.GetDB()
return db,true,nil
}

var g = wuid.NewWUID("default", nil)

func NewId() (uint64){
g.LoadH28FromMysql(newDB, "wuid")
return g.Next()
}

调用代码：

func AddUser(u *User) (int64, error) {
// db,err := orm.GetDB()
//fmt.Println(err)
o := orm.NewOrm()
u.Id = 74837477878
for i:=0;i<100;i++ {
fmt.Println(tools.NewId())
}

fmt.Println(u)
return o.Insert(u)

}

插入操作无法继续执行，

var newDB = func() (*sql.DB,bool,error){
db,_ := orm.GetDB()
return db,true,nil

这样就可以了：return db, false, nil
