一键开启美好：

go get -t github.com/jialanli/windward
    
    或
    
    cd $GOPATH/src/github.com  
    git clone https://github.com/jialanli/windward.git v1.0.1

### 方便、舒适、高效、简洁 ###

支持批量配置不同类型文件读取，举例如下:

工程目录目标配置文件1，c.json

{
      "name": "你好",
      "id": 25,
      "type": "哈哈",
      "class": {
        "data": "A",
        "ins": "无名"
      },
      "other": [
        {
          "s1": "雨落山岚",
          "s2": 55
        },
        {
          "s1": "雨落山岚晚成风",
          "s2": 99
        }
      ]
    }

目标配置文件2，c.yml

apiVersion: v1
    kind: Service
    metadata:
      name: wordpress3
      namespace: default
    spec:
      ports:
        - port: 19987
          protocol: TCP
          targetPort: 19987
      sessionAffinity: None
      type: ClusterIP

读取&注入配置：

import (
    	"fmt"
    	"github.com/jialanli/windward"
    )
    
    // 全部配置注入时定义对应结构体
    type metadata struct {
    	Name      string `yaml:"name"`
    	Namespace string `yaml:"namespace"`
    }
    
    type ports struct {
    	TargetPort int    `yaml:"targetPort"`
    	Port       int    `yaml:"port"`
    	Protocol   string `yaml:"protocol"`
    }
    
    type spec struct {
    	Ports           []ports `yaml:"ports"`
    	SessionAffinity string  `yaml:"sessionAffinity"`
    	Type            string  `yaml:"type"`
    }
    
    type YamlDemo struct {
    	Kind       string   `yaml:"kind"`
    	Metadata   metadata `yaml:"metadata"`
    	Spec       spec     `yaml:"spec"`
    	ApiVersion string   `yaml:"apiVersion"`
    }
    
    type other struct {
    	S1 string `json:"s1"`
    	S2 int    `json:"s2"`
    }
    type JsonDemo struct {
    	Name  string `json:"name"`
    	ID    int    `json:"id"`
    	Type  string `json:"type"`
    	Class struct {
    		Data string `json:"data"`
    		Ins  string `json:"ins"`
    	} `json:"class"`
    	Other []other `json:"other"`
    }
    
    func main() {
    	name, name1 := "./conf/c.json", "./conf/c.yml"  // 自定义配置文件所在目录
    	w := windward.GetWindward()
    	w.InitConf([]string{name, name1})  // 初始化自定义的配置文件
    
    	var data JsonDemo
    	err := w.ReadConfig(name, &data)  // json配置文件的全部配置

    	fmt.Println("\nmetadata.namespace-->", dataYaml.Metadata.Namespace) //
    
    // 指定单个配置获取

    	targetPort := w.GetVal(name1, "spec.ports.targetPort")
    	fmt.Println("spec.ports.targetPort-->", targetPort) //
