【springboot】【jasypt】加密密码

springboot的版本是

Spring Boot ::        (v2.1.5.RELEASE)

依赖

<dependency>
    <groupId>com.github.ulisesbocchio</groupId>
    <artifactId>jasypt-spring-boot-starter</artifactId>
    <version>2.1.1</version>
</dependency>

生成秘钥类

 import org.jasypt.encryption.pbe.StandardPBEStringEncryptor;
 import org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig;

 /**
  * 把密文放到配置文件中的时候要注意：
  * ENC(密文)
  */
 public class ConfigEncryptUtils {

     /**
      * 2.1.1
      * Spring Boot ::        (v2.1.5.RELEASE)
      * @param args
      */
     public static void main(String[] args) {

         //加密工具
         StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();

         //加密配置
         EnvironmentStringPBEConfig config = new EnvironmentStringPBEConfig();
         config.setAlgorithm("PBEWithMD5AndDES");

         //生成秘钥的公钥
         config.setPassword("xiaostudy");

         //应用配置
         encryptor.setConfig(config);

         //明文密码
         String plaintext = "123456";

         //加密
         String ciphertext = encryptor.encrypt(plaintext);

         System.out.println(plaintext + "加密后: " + ciphertext);

         //解密 过程
         String pText = encryptor.decrypt(ciphertext);
         System.out.println(ciphertext + "解密后: " + pText);
     }
 }

配置文件application.yml添加

jasypt:
  encryptor:
    password: xiaostudy

密码：

注：如果发现启动报错，可能就是springboot与jasypt版本不对
