1.使用环境
springboot:2.1.4.RELEASE
JDK:8
jasypt-spring-boot-starter:3.0.2
2.引入依赖

3.application.properties配置
server.port=8080### mybatis
mybatis.mapper-locations=classpath:mapper/*.xml
mybatis.type-aliases-package=com.xx.xx ### xxl-job, datasource
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/xxx?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&serverTimezone=Asia/Shanghai
spring.datasource.username=root
spring.datasource.password=ENC(jGfd15IFYKMjMW5bUYp06BQ8OCdHTXi3zbD4j9tw6U3PPvvA5GS8zn10kgVmgxXY)
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver#加密盐值，获取加密后的值后删除，在vmOptions配置(如下图)
jasypt.encryptor.password=123adf
加密后，可删除jasypt.encryptor.password配置；发版时可在命令行中配置
4.明文加密
@SpringBootTest
@RunWith(SpringRunner.class)
public class D2ApplicationTests {@Resourceprivate StringEncryptor jasyptStringEncryptor;@Testpublic void contextLoads() {String pwd = jasyptStringEncryptor.encrypt("root");System.out.println("pwd:" + pwd);}}
5.所遇问题
