# jasypt加密的密匙 jasypt:   encryptor:     password: Y6M9fAJQdU7jNp5MW 

@RunWith(SpringRunner.class) @SpringBootTest public class DatabaseTest { 
              @Autowired     private StringEncryptor encryptor;      @Test     public void getPass() { 
                 String url = encryptor.encrypt("jdbc:mysql://localhost:3306/mydb?autoReconnect=true&serverTimezone=GMT+8&useUnicode=true&characterEncoding=utf-8");         String name = encryptor.encrypt("root");         String password = encryptor.encrypt("123456");         System.out.println("database url: "   url);         System.out.println("database name: " + name);
        System.out.println("database password: " + password);
        Assert.assertTrue(url.length() > 0);
        Assert.assertTrue(name.length() > 0);
        Assert.assertTrue(password.length() > 0);
    }
}

下面是输出加密字符串：

注意: 上面的 ENC() 是固定写法，运行后会将加密值改为明文运行。

部署时配置salt(盐)值 为了防止salt(盐)泄露,反解出密码.可以在项目部署的时候使用命令传入salt(盐)值:

java -jar xxx.jar -Djasypt.encryptor.password=Y6M9fAJQdU7jNp5MW

或者在服务器的环境变量里配置,进一步提高安全性. 打开/etc/profile文件

vim /etc/profile

在profile文件末尾插入salt(盐)变量

export JASYPT_PASSWORD = Y6M9fAJQdU7jNp5MW

编译，使配置文件生效

source /etc/profile

运行

java -jar -Djasypt.encryptor.password=${ 
        JASYPT_PASSWORD} xxx.jar
