我们可以通过DB.Stats方法获取orm对象的连接池状态。我们来看个示例：
| Code Block | ||
|---|---|---|
| ||
package main
import (
_ "github.com/gogf/gf/contrib/drivers/mysql/v2"
"github.com/gogf/gf/v2/database/gdb"
"github.com/gogf/gf/v2/frame/g"
"github.com/gogf/gf/v2/os/gctx"
)
func main() {
var ctx = gctx.New()
db, err := gdb.New(gdb.ConfigNode{
Link: "mysql:root:12345678@tcp(127.0.0.1:3306)/test",
})
if err != nil {
g.Log().Fatal(ctx, err)
}
err = db.PingMaster()
if err != nil {
g.Log().Fatal(ctx, err)
}
stats := db.Stats(ctx)
g.Dump(stats)
} |
执行后，终端输出如下，可以看到每个链接的数据库节点以及对应的连接池状态信息。
