Java java.io.IOException: Invalid keystore format问题解决

        Caused by: java.io.IOException: Invalid keystore format

1、使用KeyStore.load()方法merlion.jks文件不对导致报错。

    
    @Bean
    public KeyPair keyPair() {
        try (InputStream inputStream = new ClassPathResource("keystore/merlion.jks").getInputStream()) {
            KeyStore keyStore = KeyStore.getInstance("jks");
            String alias = "merlion";
            char[] password = "admin@123".toCharArray();
            keyStore.load(inputStream, password);
            PrivateKey privateKey = (PrivateKey) keyStore.getKey(alias, password);
            PublicKey publicKey = keyStore.getCertificate(alias).getPublicKey();
            return new KeyPair(publicKey, privateKey);
        } catch (IOException | KeyStoreException | NoSuchAlgorithmException | CertificateException | UnrecoverableKeyException e) {
            throw new RuntimeException(e);
        }
    }

解决办法：

        打开jdk的bin目录，进入cmd窗口，执行keytool -genkey -alias merlion -keyalg RSA -storepass admin@123 -keysize 1024 -keystore merlion.jks -validity 3655命令，重新生成merlion.jks文件。再把生成的merlion.jks文件替换项目中原有的merlion.jks文件。
