mysql pool 查询为空

发现了一个不错的包，地址为：https://github.com/hopehook/golang-db 大致把mysql 连接池封装了起来，看着很不错的样子 我尝试了一下，查询为空，不知道为什么，那位高人给看看： my main package: ``` package main import( "github.com/gin-gonic/gin" "net/http" "fecshop.com/module/user" //"fecshop.com/common/cdb" _ "github.com/go-sql-driver/mysql" mysqlPool "github.com/hopehook/golang-db/mysql" ) func mysqlDBPool() *mysqlPool.SQLConnPool{ host := `127.0.0.1:3306` database := `go_test` user := `root` password := `xxx` charset := `utf8` // 用于设置最大打开的连接数 maxOpenConns := 200 // 用于设置闲置的连接数 maxIdleConns := 100 mysqlDB := mysqlPool.InitMySQLPool(host, database, user, password, charset, maxOpenConns, maxIdleConns) return mysqlDB } func main() { mysqlDB := mysqlDBPool(); r := gin.Default() v2 := r.Group("/v2") { // 查询部分 v2.GET("/users", func(c *gin.Context) { data := user.List2(mysqlDB); c.JSON(http.StatusOK, data) }) } r.Run("120.24.37.249:3000") // listen and serve on 0.0.0.0:8080 } ``` my user package code : ``` package user import ( "fmt" "github.com/gin-gonic/gin" mysqlPool "github.com/hopehook/golang-db/mysql" ) func List2(mysqlDB *mysqlPool.SQLConnPool) gin.H{ body := make(gin.H) rows, err := mysqlDB.Query("SELECT * From user") if err != nil { fmt.Printf("%s\r\n","mysql query error") } fmt.Printf("%v\r\n",rows) var dbdata []gin.H if rows != nil { for _, row := range rows { h := make(gin.H) for k,v := range row { h[k] = v } dbdata = append(dbdata, h) } } body["data"] = dbdata return body } ``` `fmt.Printf("%v\r\n",rows)` : ``` [map[] map[] map[] map[] map[] map[] map[] map[] map[]] ``` return empty go_test.user: ``` CREATE TABLE IF NOT EXISTS `user` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `name` varchar(20) DEFAULT '', `age` int(11) DEFAULT '0', PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=11 ; -- -- 转存表中的数据 `user` -- INSERT INTO `user` (`id`, `name`, `age`) VALUES (1, '111', 111), (2, 'terry', 44), (3, 'terry', 55), (4, 'terry', 44), (5, 'terry', 44), (6, 'terry', 44), (7, 'terry', 44), (8, 'te11rry', 929), (10, 'terry', 66); ``` can you help me ? thank you!
