硬编码问题

Jasypt maven 插件

1. 添加依赖

<!-- https://mvnrepository.com/artifact/com.github.ulisesbocchio/jasypt-spring-boot-starter -->
<dependency>
    <groupId>com.github.ulisesbocchio</groupId>
    <artifactId>jasypt-spring-boot-starter</artifactId>
    <version>3.0.5</version>
</dependency>

2. 配置插件

<!--jasypt-maven-plugin-->
<plugin>
    <groupId>com.github.ulisesbocchio</groupId>
    <artifactId>jasypt-maven-plugin</artifactId>
    <version>3.0.5</version>
    <configuration>
        <path>file:src/main/resources/application.yml</path>
    </configuration>
</plugin>

3. 配置文件

server:
  port: 9527

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url-helper: DEC(localhost:3306/test)
    url: jdbc:mysql://${spring.datasource.url-helper}?useSSL=false&useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai
    username: DEC(ROOT)
    password: DEC(123456)
  redis:
    host: DEC(localhost)
    port-helper: DEC(6379)
    port: ${spring.redis.port-helper}
    password: DEC(123456)
jasypt:
  encryptor:
    password: DEC(123456)

4. 执行命令

mvn jasypt:encrypt

或者点击idea中的插件 jasypt -> jasypt:encrypt

5. 删除配置文件中的jasypt.encryptor.password配置
6. 打包
7. 生产运行项目，并设置jasypt.encryptor.password参数 这个参数得和配置文件中设置的密码一致

java -jar target/Jasypt-1.0-SNAPSHOT.jar --jasypt.encryptor.password="DEC(123456)"

或者

java -Djasypt.encryptor.password="DEC(123456)" -jar target/Jasypt-1.0-SNAPSHOT.jar

8. 访问接口，获取配置文件，得到解密后的数据
