IntelliJ IDEA 远程激活服务器搭建教程

不建议你们使用此方法激活，若资金容许，请点击https://www.jetbrains.com/idea/buy/购买正版，谢谢合做！

前言

用过 IDEA 的同窗应该都知道，这个软件是收费的，对于笔者来讲是很贵了，所以只能另寻他法。 咱们能够很轻松的从网上找到搭建本地激活服务器的教程，可是每次打开 IDEA 都要先打开激活服务器，太麻烦。 或者从网上找别人搭建好的激活服务器，可是可能某一天忽然就用不了了，因此若是有条件仍是本身搭建一个激活服务器比较靠谱。

要求

一台能够远程访问的主机 一个 Spring web 项目

动手

打开咱们的 Spring 项目，若是没有的话请自行百度教程，添加一个 Controller

@RestController
@RequestMapping("/rpc")
public class LicenseController {

    @RequestMapping("/obtainTicket.action")
    public String obtainTicket(String salt, String userName) throws Exception {
        String content = "<ObtainTicketResponse>" +
                "<message></message>" +
                "<prolongationPeriod>607875500</prolongationPeriod>" +
                "<responseCode>OK</responseCode>" +
                "<salt>" + salt + "</salt>" +
                "<ticketId>1</ticketId>" +
                "<ticketProperties>licensee=" + userName + " licenseType=0 </ticketProperties>" +
                "</ObtainTicketResponse>";
        return LicenseUtils.rsaSign(content);
    }

    @RequestMapping("/releaseTicket.action")
    public void releaseTicket(HttpServletResponse httpServletResponse) {
        httpServletResponse.setStatus(HttpServletResponse.SC_NOT_FOUND);
    }

    @RequestMapping("ping.action")
    public String ping(String salt) throws Exception {
        String content = "<PingResponse>" +
                "<message></message>" +
                "<responseCode>OK</responseCode>" +
                "<salt>" + salt + "</salt>" +
                "</PingResponse>";
        return LicenseUtils.rsaSign(content);
    }
}

添加工具类

public class LicenseUtils {

    public static String rsaSign(String content) throws Exception {
        PrivateKey pk = getPrivateKey();
        RSAPrivateKey rpk = (RSAPrivateKey) pk;
        byte[] a = hashed(content);
        byte[] result = sign(rpk, a);
        String mm = byte2HexStr(result).toLowerCase();
        return "<!-- " + mm + " -->\n" + content;
    }

    private static PrivateKey getPrivateKey() throws Exception {
        String priKeyData = "MIIBVQIBADANBgkqhkiG9w0BAQEFAASCAT8wggE7AgEAAkEAt5yrcHAAjhglnCEn" +
                "6yecMWPeUXcMyo0+itXrLlkpcKIIyqPw546bGThhlb1ppX1ySX/OUA4jSakHekNP" +
                "5eWPawIDAQABAkBbr9pUPTmpuxkcy9m5LYBrkWk02PQEOV/fyE62SEPPP+GRhv4Q" +
                "Fgsu+V2GCwPQ69E3LzKHPsSNpSosIHSO4g3hAiEAywlDfGIl6acnakPrmJE0IL8q" +

                "7MHx821EWbGc";
        byte[] keyBytes = Base64.getDecoder().decode(priKeyData.getBytes());
        PKCS8EncodedKeySpec keySpec = new PKCS8EncodedKeySpec(keyBytes);
        KeyFactory keyFactory = KeyFactory.getInstance("RSA");
        return keyFactory.generatePrivate(keySpec);
    }

    private static byte[] hashed(String content) throws NoSuchAlgorithmException {
        byte[] bytes = content.getBytes();
        MessageDigest digest = MessageDigest.getInstance("MD5");
        return digest.digest(bytes);
    }

    private static byte[] sign(RSAPrivateKey pri, byte[] hashed) throws NoSuchAlgorithmException, InvalidKeyException, SignatureException {
        int hashLen = hashed.length;
        byte[] prefix = new byte[]{48, 32, 48, 12, 6, 8, 42, -122, 72, -122, -9, 13, 2, 5, 5, 0, 4, 16};
        int tLen = prefix.length + hashLen;
        int k = (pri.getModulus().bitLength() + 7) / 8;

        byte[] em = new byte[k];
        em[1] = (byte) 1;
        for (int i = 2; i < k - tLen - 1; i++) {
            em[i] = (byte) 0xFF;
        }
        System.arraycopy(prefix, 0, em, k - tLen, prefix.length);
        System.arraycopy(hashed, 0, em, k - hashLen, hashLen);
        BigInteger m = new BigInteger(em);
        byte[] src = m.modPow(pri.getPrivateExponent(), pri.getModulus()).toByteArray();
        int numPaddingBytes = em.length - src.length;
        for (int i = 0; i < numPaddingBytes; i++) {
            em[i] = 0;
        }
        if (src.length > em.length) {
            System.arraycopy(src, 1, em, numPaddingBytes + 1, src.length - 1);
        } else {
            System.arraycopy(src, 0, em, numPaddingBytes, src.length);
        }
        return em;
    }

    private static String byte2HexStr(byte[] bytes) {
        StringBuilder sb = new StringBuilder();
        for (byte b : bytes) {
            String tmp = Integer.toHexString(b & 0xFF);
            sb.append((tmp.length() == 1) ? ("0" + tmp) : tmp);
        }
        return sb.toString().toUpperCase().trim();
    }
}

而后打包，部署。 部署成功后把 IDEA 的激活服务器地址改成你的项目的地址（不带/rpc），就能够愉快的激活 IDEA 了。

福利

若是实在没条件本身搭建服务器，能够用笔者搭建好的激活服务器地址，低调使用，否则可能会被封

最后重申一下，不建议你们使用此方法激活，若资金容许，请点击https://www.jetbrains.com/idea/buy/购买正版，谢谢合做！
