1.application.yml配置

2.利用jaspty工具类将数据库密码明文加密

/**
     * 明文加密
     */
    public static String encrypt(String str,String pwd) {
        BasicTextEncryptor basicTextEncryptor = new BasicTextEncryptor();
        basicTextEncryptor.setPassword(pwd);
        String ciphertext = basicTextEncryptor.encrypt(str);
        return ciphertext;
    }

    /**
     * 解密
     */
    public static String decrypt(String ciphertext,String pwd) {
        BasicTextEncryptor basicTextEncryptor = new BasicTextEncryptor();
        basicTextEncryptor.setPassword(pwd);
        ciphertext = "ENC(" + ciphertext + ")";
        if (PropertyValueEncryptionUtils.isEncryptedValue(ciphertext)) {
            String plaintext = PropertyValueEncryptionUtils.
decrypt(ciphertext, basicTextEncryptor);
            return plaintext;
        }
        return "";
    }

 public static void main(String[] args) {
        String str = encrypt("xjmfc1","123456");

        System.out.println(str);

    }
