You can use a field tag to tell exactly how the name should look like:

ReportSeconds int64 `yaml:"reportSeconds"`

from yaml.

By the way, there's full documentation for these options at:

http://gopkg.in/yaml.v2#Marshal

from yaml.

Oh sorry, thanks for the help!

from yaml.

ReportSeconds int64 `yaml:"reportSeconds"`

it doesnt work

the yaml file:

max: 1
maxIdleConnections: 10
max_open_connections: 10

the demo code here:

package main

import (
	"fmt"
	"gopkg.in/yaml.v3"
	"io/ioutil"
)

func main() {
	
	
	// 加载配置
	var d Database
	d.LoadConfig("config.yaml")
	
	fmt.Println(d.Max)
	fmt.Println(d.MaxOpenConnections)
	fmt.Println(d.MaxOpenConnections)
}

// 映射 总配置信息
type Database struct {
	Max	                int		    `yaml: "max"`
	MaxIdleConnections	int64       `yaml: "maxIdleConnections"`
	MaxOpenConnections	int64       `yaml: 'max_open_connections'`
}

func (configuration *Database)LoadConfig(filename string){
	//应该是 绝对地址
	yamlFile, err := ioutil.ReadFile(filename)
	if err != nil {
		fmt.Println(err.Error())
	}
	err = yaml.Unmarshal(yamlFile, configuration)
	if err != nil {
		fmt.Println(err.Error())
	}
}
