使用jasypt对yml中的数据进行加密

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

使用方法有以下三种

基础使用

/**
    * 加密
    */
    @Test
    public void testEncrypt(){
        StandardPBEStringEncryptor standardPBEStringEncryptor = new StandardPBEStringEncryptor();
        EnvironmentPBEConfig config = new EnvironmentPBEConfig();
        // 加密的算法
        config.setAlgorithm("PBEWithMD5AndDES");
        // 加密的密钥，类似于盐，不要告诉别人
        config.setPassword("Hello");

        standardPBEStringEncryptor.setConfig(config);
        // 明文
        String plainText = "123456";
        // 加密后的密文
        String encryptText = standardPBEStringEncryptor.encrypt(plainText);
        System.out.println(encryptText);
    }

    /**
    * 解密
    */
    @Test
    public void testDecrypt(){
        StandardPBEStringEncryptor standardPBEStringEncryptor = new StandardPBEStringEncryptor();
        EnvironmentPBEConfig config = new EnvironmentPBEConfig();
        // 加密的算法
        config.setAlgorithm("PBEWithMD5AndDES");
        // 加密的密钥，类似于盐，不要告诉别人
        config.setPassword("Hello");

        standardPBEStringEncryptor.setConfig(config);
        String encryptText = "l6jdd5zFTWVuxxAL2lq19w==";
        String decryptText = standardPBEStringEncryptor.decrypt(encryptText);

        System.out.println(decryptText);
    }

注解使用

也可以使用注解

@Resource
private StringEncryptor stringEncryptor;

stringEncryptor.encrypt()

推荐：配置文件中使用ENC()直接解密
