有没有办法让jasypt在Springboot中具有自定义加密功能

Question

请就如何实现这一点提出一个方法？

=========================================================================================================

jaspyt提供了3种不同的密码解密方法。我尝试了前两种方法，并且能够成功地加密/解密，但问题是密钥必须作为环境或系统属性传递。

第三种方法是使用自定义JASYPT加密器。我想这个解决方案就是我想要的，在这里我可以将密码保存在外部文件中，并从bootstrap.yml传递路径。

pom.xml

<dependency>
     <groupId>com.github.ulisesbocchio</groupId>
     <artifactId>jasypt-spring-boot-starter</artifactId>
     <version>1.18</version>
</dependency>

配置类

@Bean(name = "encryptorBean")
public StringEncryptor stringEncryptor() {
    PooledPBEStringEncryptor encryptor = new PooledPBEStringEncryptor();
    SimpleStringPBEConfig config = new SimpleStringPBEConfig();
    \\ will add code here to get the password from the file                                 
    config.setPassword("Read from a file"); 
    config.setAlgorithm("PBEWithMD5AndDES");
    config.setKeyObtentionIterations("1000");
    config.setPoolSize("1");
    config.setProviderName("SunJCE");
    config.setSaltGeneratorClassName("org.jasypt.salt.RandomSaltGenerator");
    config.setStringOutputType("base64");
    encryptor.setConfig(config);
    return encryptor;
}

jasypt:
  encryptor:
    bean: encryptorBean

Answer 1

将bean名称更改为JasyptStringEncryptor：

> @Bean(name = "jasyptStringEncryptor") public StringEncryptor
> stringEncryptor() {

或

设置jasypt.encryptor.bean属性

jasypt.encryptor.bean=encryptorBean
