springboot配置

jasypt:encryptor:password: saltValue    #salt值，密文加盐
spring:datasource: # 数据库链接db1:jdbc-url: jdbc:mysql://x.x.x.x:3306/db_test?useUnicode=true&characterEncoding=utf8&useSSL=false&allowPublicKeyRetrieval=true&serverTimezone=GMT%2B8username: root      #也可以加密用户名,依然是ENC()格式，这里没有进行加密password: ENC(OVL1V3KDtTa8w9IIOVuSdeyCOsZXAN0+)  #加密了密码，ENC()括号内为密文driver-class-name: com.mysql.cj.jdbc.Drivermapper-locations: classpath*:mapper/otcmapper/*.xml

启动类添加注解：@EnableEncryptableProperties

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
@EnableEncryptableProperties
@EnableScheduling
//@EnableAsync
public class SpBatchApplication {public static void main(String[] args) {SpringApplication.run(SpBatchApplication.class, args);}
}

通过明文获取加密的值

• cmd在自己的maven仓库目录下执行命令，（要保证依赖下载下来了）
  解释：
  input：文字的明文
  password：加密的盐值（可随意，必须=jasypt:encryptor:password: saltValue）
  algorithm：PBEWithMD5AndDES（默认算法）

java -cp org/jasypt/jasypt/1.9.2/jasypt-1.9.2.jar org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI input="密码明文" password=saltValue algorithm=PBEWithMD5AndDES

执行后输出结果：OUTPUT就是密文了，把密文替换yml的属性值就行
ENC(OVL1V3KDtTa8w9IIOVuSdeyCOsZXAN0+)

----ARGUMENTS-------------------algorithm: PBEWithMD5AndDES
input: 密码明文
password: saltValue----OUTPUT----------------------OVL1V3KDtTa8w9IIOVuSdeyCOsZXAN0+

启动springboot就会自动解密了

通过密文和盐值解密得到明文

java -cp jasypt-1.9.2.jar org.jasypt.intf.cli.JasyptPBEStringDecryptionCLI input="加密后的密文" password=saltValue algorithm=PBEWithMD5AndDES
