java - 在 Spring Boot Web 应用程序中使用加密密码进行数据库连接

Question

这可能已经被其他人回答或询问过，但我无法找到满足我的用例的答案。我正在我的 Spring Boot Web 应用程序中建立数据库连接(注意:我的应用程序打包为“WAR”，并且不包含嵌入式 tomcat)，方法是在我的 application.properties 文件中指定以下属性。

spring.datasource.driver-class-name=com.teradata.jdbc.TeraDriver
spring.datasource.url=jdbc:teradata://localhost/database=test
spring.datasource.username=root
spring.datasource.password=root

通过使用上述属性，我能够成功建立数据库连接，现在我想放置一个加密密码而不是简单密码。我正在使用下面的命令来加密密码

java -cp jasypt-1.9.2.jar org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI input="mypassword" password=SimplePassword algorithm=PBEWithMD5AndDES

我得到的加密文件为“IlwjvmfqoPXVbyue17zN6Hx8mlJnGIuu”，我将其放置在属性文件中，如下所示

spring.datasource.password=ENC(IlwjvmfqoPXVbyue17zN6Hx8mlJnGIuu)

但是 spring 无法将其识别为加密的(因为，我没有指定它是加密值的任何位置，并且在使用它之前需要对其进行解密。

我对 Spring Boot 开发相当陌生，如果有人知道如何做到这一点，请指导我，那将非常有帮助。我已点击此链接，但无法使其正常工作“https://www.baeldung.com/spring-boot-jasypt ”

根据@梦のの梦的回复，我已经添加了依赖项并将版本设置为2.1.0，属性“jasypt.encryptor.password=SimplePassword”我已将其添加到文件“application.properties”中我能够完美地构建应用程序，并且它成功地建立了连接池，但是当我从 eclipse 在 tomcat 服务器上运行它时，我收到以下错误

我在这里做错了什么其他配置吗？，为什么我的应用程序能够正常构建，所有测试都成功完成，但无法在服务器上运行？，如果有人看到上述错误，请告诉我原因导致该错误。谢谢大家。

Answer 1

Since, i am not specifying any where that it is a encrypted value and it needs to be decrypted before using it

你不需要。如果您包含以下依赖项，Spring Boot 会自动为您配置默认的 jasypt。您只需确保将 key 添加到虚拟机中，例如 Djasypt.encryptor.password=SimplePassword

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