1. 需求讲解

对配置文件的组件密码加密,比如数据库redis等密码加密

2. 开发

2.1 依赖引入

        <!-- jasypt 加解密 --><dependency><groupId>com.github.ulisesbocchio</groupId><artifactId>jasypt-spring-boot-starter</artifactId><version>2.1.2</version></dependency>

2.2 加密解密代码

package com.imooc.test;import org.jasypt.encryption.pbe.StandardPBEStringEncryptor;
import org.jasypt.encryption.pbe.config.EnvironmentPBEConfig;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;@SpringBootTest
public class JasyptTest {@Testpublic void testPwdEncrypt() {// 实例化加密器StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();// 配置加密算法和秘钥EnvironmentPBEConfig config = new EnvironmentPBEConfig();config.setPassword("fengjianyingyue");      // 用于加密的秘钥(盐)，可以是随机字符串，或者固定，一定要存储好，不要被其他人知道config.setAlgorithm("PBEWithMD5AndDES");    // 设置加密算法，默认encryptor.setConfig(config);// 对密码进行加密String myPwd = "imooc";String encryptedPwd = encryptor.encrypt(myPwd);System.out.println("++++++++++++++++++++++++++++++");System.out.println("+ 原密码为：" + myPwd);System.out.println("+ 加密后的密码为：" + encryptedPwd);System.out.println("++++++++++++++++++++++++++++++");}
}

2.3 配置文件配置jasypt属性

jasypt:encryptor:algorithm: PBEWithMD5AndDES password: fengjianyingyue

2.4 加密密码

在ENC()里面写加密后的密码即可,开箱即用

  rabbitmq:host: 121.43.139.228port: 5672virtual-host: /username: imoocpassword: ENC(UnoiHtPp84zMjjwLoJe/Kg==)
