使用Jasypt对SpringBoot配置文件加密(数据源为SpringBoot默认的数据源HikariDataSource)

引入Jasypt依赖

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

将要加密的数据进行加密，例如数据库名，数据库密码

  public static void main(String[] args) {
        BasicTextEncryptor textEncryptor = new BasicTextEncryptor();
        //加密所需的salt(盐)，随便写
        textEncryptor.setPassword("G0CvDz7oJn6");
        //要加密的数据（数据库的用户名或密码）
        String username = textEncryptor.encrypt("root");
        String password = textEncryptor.encrypt("root123");
        System.out.println("username:"+username);
        System.out.println("password:"+password);
    }

输出信息为

username:i8QgEN4uOy2E1rHzrpSTYA==
password:6eaMh/RX5oXUVca9ignvtg==

配置yml文件，将生成的加密字符加入到ENC(加密字符串)

spring:
  datasource:
    username: ENC(i8QgEN4uOy2E1rHzrpSTYA==)
    password: ENC(6eaMh/RX5oXUVca9ignvtg==)
    url: jdbc:oracle:thin:@localhost:1521:data
    type: com.zaxxer.hikari.HikariDataSource
    driver-class-name: oracle.jdbc.driver.OracleDriver
