配置文件config.yml
mysql:
type: mysql
dsn: "user:pass@tcp(localhost:30306)/db_name?charset=utf8&parseTime=True&loc=Local"
maxopen: 100
maxidle: 10
maxlifetime: 300
redis:
host: 127.0.0.1
port: 3306
读取配置文件
package config
import (
"github.com/spf13/viper"
"path"
"runtime"
"time"
)
type mysqlConfig struct { // 配置属性跟类型字段不同名是要加下面这个tag
Type string `mapstructure:"type"`
DSN string `mapstructure:"dsn"`
MaxOpenConn int `mapstructure:"maxopen"`
MaxIdleConn int `mapstructure:"maxidle"`
MaxLifeTime time.Duration `mapstructure:"maxlifetime"`
}
type redisConfig struct { // 配置属性跟类型字段不同名是要加下面这个tag
Host string `mapstructure:"host"`
Port string `mapstructure:"port"`
}
var Mysql *mysqlConfig
var Redis *redisConfig
func init() {
// 获取当前文件的路径
_, filename, _, _ := runtime.Caller(0)
// 配置文件目录的路径
configBaseDir := path.Dir(filename)
vp := viper.New()
vp.AddConfigPath(configBaseDir)
vp.SetConfigType("yaml")
err := vp.ReadInConfig()
if err != nil {
panic(err)
}
vp.UnmarshalKey("mysql", &Mysql)
vp.UnmarshalKey("redis", &Redis)
Mysql.MaxLifeTime *= time.Second
}
调用配置内容
import (
"fmt"
"lianxi/config"
)
func main() {
fmt.Println(config.Redis.Port)
fmt.Println(config.Mysql.Type)
}
