重写解密处理类

@Component("encryptablePropertyResolver")
public class BasicEncryptablePropertyResolver implements EncryptablePropertyResolver {
    private final PooledPBEStringEncryptor encryptor;
    /**
     * 标识配置文件中需要解密的值前缀
     */
    private final String prefix = "ENC[";
    /**
     * 标识配置文件中需要解密的值后缀
     */
    private final String suffix = "]";
​
    public BasicEncryptablePropertyResolver(){
        encryptor = new PooledPBEStringEncryptor();
        SimpleStringPBEConfig config = new SimpleStringPBEConfig();
        //加密盐
        config.setPassword("mioto-project");
        config.setAlgorithm("PBEWithMD5AndDES");
        config.setKeyObtentionIterations("1000");
        config.setPoolSize("1");
        config.setProviderName("SunJCE");
        config.setSaltGeneratorClassName("org.jasypt.salt.RandomSaltGenerator");
        config.setIvGeneratorClassName("org.jasypt.iv.RandomIvGenerator");
        config.setStringOutputType("base64");
        encryptor.setConfig(config);
    }
​
    @Override
    public String resolvePropertyValue(String value) {
        if (value != null && value.startsWith(prefix) && value.endsWith(suffix)) {
            return encryptor.decrypt(value.substring(prefix.length() - 1));
        }
        return value;
    }
}

加解密测试

 

 public static void main(String[] args) {
        BasicEncryptablePropertyResolver encryptablePropertyResolver = new BasicEncryptablePropertyResolver();
        System.out.println(encryptablePropertyResolver.encryptor.encrypt("mioto88888"));
        System.out.println(encryptablePropertyResolver.resolvePropertyValue("mioto[gzhFpmXjYXyITMDOZsCZylyBZuQkylidN/d4BfBu860=]"));
    }

 

编写配置文件需加密属性值

 

spring.datasource.password=ENC[gYwKmL6bj7TSqondKvfnWhC9DYT9IsKvVkpsl+ve6Gw=]

 备注

1. jasypt每次加密的结果都不相同，但是解密的结果是一致的
2. 配置需加密的属性值时，将加密后的值放入到prefix和suffix中
3. 重写的处理类必须为encryptablePropertyResolver
