在Spring Boot Web应用程序中使用加密密码进行数据库连接

时间：2019-01-22 21:33:18

标签： java spring-boot spring-mvc jasypt

可能已经有人回答或问过这个问题，但是我找不到能满足用例的问题。 通过在application.properties文件中指定以下属性，我在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）。

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

通过使用以上属性，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。我正在使用以下命令使用以下命令对密码进行加密

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”，并将其如下所示放置在属性文件中

spring.datasource.password=ENC(IlwjvmfqoPXVbyue17zN6Hx8mlJnGIuu)

但是spring无法将其标识为已加密（因为我没有在任何地方指定它是加密值，因此在使用它之前需要对其进行解密。

我对Spring Boot的开发还很陌生，如果有人知道怎么做，请指导我，这真的很有帮助。我已跟踪此链接，但无法使其正常运行“ https://www.baeldung.com/spring-boot-jasypt”

根据@梦のの梦的回复，我已经添加了依赖性，并将版本设为2.1.0，并将属性“ jasypt.encryptor.password = SimplePassword”添加到了文件“ application.properties”中。并且我能够完美地构建应用程序，并且成功建立了连接池，但是当我从eclipse的tomcat服务器上运行它时，出现以下错误

我在这里做任何其他配置错误吗？为什么我的应用程序能够在所有测试成功完成但无法在服务器上运行的情况下正常构建？如果有人看到以上错误，请告诉我为什么导致该错误。 谢谢大家。

自此，我没有在任何地方指定它是加密值，并且在使用它之前需要对其进行解密

您不需要。如果您包括以下依赖项，Spring Boot会自动为您配置默认的jasypt。您只需要确保将密钥添加到VM中即可，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>
