一、项目目录树结构

由于时间有限，不可能在博客上花太多时间、也不可能每一个细节都说的很细，所以，下面的内容虽然一时间看着比较懵，但是文末有项目的GitHub地址，或者不懂的可以留言；

这个是粗糙的项目结构，没有细分，实际应用的话应该是授权的代码要和验证的代码分开，防止授权的代码引进客户端系统中，被破解和拆穿，也为了防止公钥store被客户端用户串改；

正确、良好的结构应该是如下的：

由于上面的结构里面引入了其他包，故在最后，我就不放这个结构的代码在我的github上了

二、如何生成秘钥对

网上有，这个不再细说了，直接上文本：

1、首先要用KeyTool工具来生成私匙库：（-alias别名 –validity 3650表示10年有效）
keytool -genkey -alias privatekey -keystore privateKeys.store -validity 3650

2、然后把私匙库内的公匙导出到一个文件当中：
keytool -export -alias privatekey -file certfile.cer -keystore privateKeys.store

3、然后再把这个证书文件导入到公匙库：
keytool -import -alias publiccert -file certfile.cer -keystore publicCerts.store

最后生成文件privateKeys.store、publicCerts.store拷贝出来备用。

三、如何应用

（1）获取服务器硬件信息

访问地址：localhost:8066/license/getServerInfos

{
    "ipAddress": [
        "10.16.248.102"
    ],
    "macAddress": [
        "58-00-E3-D4-83-2B"
    ],
    "cpuSerial": "BFEBFBFF000506E3",
    "mainBoardSerial": "",
    "macCheck": false,
    "ipCheck": false,
    "cpuCheck": false,
    "boardCheck": false
}

（2）生成许可文件

生成接口：localhost:8066/license/generateLicense

注册信息：

{
	"subject": "landi",
	"privateAlias": "privateKey",
	"keyPass": "123456a",
	"storePass": "123456a",
	"licensePath": "F:\\app\\license.lic",
	"privateKeysStorePath": "/privateKeys.store",
	"issuedTime": "2019-09-26 14:50:00",
	"expiryTime": "2019-09-27 17:45:55",
	"consumerType": "User",
	"consumerAmount": 1,
	"description": "这是证书描述信息",
	"licenseCheck": {
		"ipCheck":true,
		"ipAddress": [
			"10.16.248.102", "10.0.5.22"
		],
		"macCheck":true,
		"macAddress": [
			"58-00-E3-D4-83-2B", "50-7B-9D-F9-18-41"
		],
		"cpuSerial": "BFEBFBFF000406E3",
		"mainBoardSerial": "L1HF65E00X9"
	}
}

注册结果：

{
    "result": "ok",
    "msg": {
        "subject": "landi",
        "privateAlias": "privateKey",
        "keyPass": "123456a",

            ],
            "macAddress": [

                "50-7B-9D-F9-18-41"
            ],

            "mainBoardSerial": "L1HF65E00X9",
            "macCheck": true,
            "ipCheck": true,
            "cpuCheck": false,
            "boardCheck": false
        }
    },
    "date": "证书安装成功，证书有效期：2019-09-26 14:50:00 - 2019-09-27 17:45:55"
}
