【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：

ENC(Gs5skfuo8ovc/gSeQ45UlBF2fMWqipMksESuQPYIpao=)

注：如果发现启动报错，可能就是springboot与jasypt版本不对
