一：pom

<!-- Jasypt加密 -->
<dependency>
    <groupId>com.github.ulisesbocchio</groupId>
    <artifactId>jasypt-spring-boot-starter</artifactId>
    <version>2.0.0</version>
</dependency>

二：yml配置文件中引入passwodk，也就是鹽

# 配置文件加密key
jasypt:
  encryptor:
    password: panther

三：創(chuàng)建工具包

package com.xxx.xxx.xxx;

import org.jasypt.encryption.pbe.PooledPBEStringEncryptor;
import org.jasypt.encryption.pbe.StandardPBEByteEncryptor;
import org.jasypt.encryption.pbe.config.SimpleStringPBEConfig;

        return result;
    }

        return result;
    }

        config.setAlgorithm(StandardPBEByteEncryptor.DEFAULT_ALGORITHM);
        config.setKeyObtentionIterations("1000");
        config.setPoolSize("1");
        config.setProviderName(null);
        config.setSaltGeneratorClassName("org.jasypt.salt.RandomSaltGenerator");
        config.setStringOutputType("base64");
        return config;
    }

    public static void main(String[] args) {
        // 加密
        System.out.println(encryptPwd("EbfYkitulv73I2p0mXI50JMXoaxZTKJ7", "root@1234"));
        // 解密
//        mysql@1234
//        System.out.println(decyptPwd("EbfYkitulv73I2p0mXI50JMXoaxZTKJ7", "bgWQ4OfVCUJ1ExsqNhGV+KKBgpx8alv+"));

//        root@1234
//        System.out.println(decyptPwd("EbfYkitulv73I2p0mXI50JMXoaxZTKJ7", "tdHzge8YvviOJaiV/+P6uQ9wgB44D1aH"));
    }

}

四：使用方法
運(yùn)行main方法僚楞，填入配置的鹽毫缆，然后填入需要加密的value玲躯，直接運(yùn)行即可。

類似配置文件中的數(shù)據(jù)庫(kù)連接
