SpringBoot配置文件密码加密保存笔记

Springboot低版本，2.x

引入jar包

<dependency>
            <groupId>com.github.ulisesbocchio</groupId>
            <artifactId>jasypt-spring-boot-starter</artifactId>
            <version>2.1.0</version>
        </dependency>

编辑测试类

//加密
@Test
    public void testEncrypt() {
        StandardPBEStringEncryptor standardPBEStringEncryptor = new StandardPBEStringEncryptor();
        EnvironmentPBEConfig config = new EnvironmentPBEConfig();
 
        config.setAlgorithm("PBEWithMD5AndDES");          // 加密的算法，这个算法是默认的
        config.setPassword("Angel");                        // 加密的密钥，随便自己填写，很重要千万不要告诉别人
        standardPBEStringEncryptor.setConfig(config);
        String plainText = "123456";         //自己的密码
        String encryptedText = standardPBEStringEncryptor.encrypt(plainText);
        System.out.println(encryptedText);
    }

//解密
@Test
    public void testDe() {
        StandardPBEStringEncryptor standardPBEStringEncryptor = new StandardPBEStringEncryptor();
        EnvironmentPBEConfig config = new EnvironmentPBEConfig();
 
        config.setAlgorithm("PBEWithMD5AndDES");
        config.setPassword("Angel");
        standardPBEStringEncryptor.setConfig(config);
        String encryptedText = "4o+eS8OaWQ7HcjVgrkoX0A==";   //加密后的密码
        String plainText = standardPBEStringEncryptor.decrypt(encryptedText);
        System.out.println(plainText);
    }

yml配置

spring:
 datasource:
  username: root
  password: ENC(4o+eS8OaWQ7HcjVgrkoX0A==)  //固定格式ENC()，括号里填加密字符串
  url: jdbc:mysql://localhost:3306/test?
 
jasypt:
 encryptor:
  password: Angel        //密钥，自定义
  algorithm: PBEWithMD5AndDES        //加密算法，默认

}

手动配置了JCE的方法来支持加密程序，然而jasypt3.x版本对于jdk8自带的jce包不兼容，需要升级一下，所以下载jdk8对应的jce_policy-8，里面有两个jar包然后到jdk路径下：C:\Program Files\Java\jdk1.8.0_25\jre\lib\security去替换即可

否则运行报错

org.jasypt.exceptions.EncryptionOperationNotPossibleException: Encryption raised an exception. A possible cause is you are using strong encryption algorithms and you have not installed the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files in this Java Virtual Machine
