Spring Boot应用程序属性解密jpa密码

Question

Hi I have a Spring Boot application properties file where I configured the JPA datasource details such as username, url, password, etc. The password I have encrypted using my own encryption method from another jar file. So the password is something like

spring.datasource.password="ASDFIOM#KFS(@JSDF@N2"

I made up a random password for the sake of an example. But now I want to decrypt that password but the moment you run spring boot it opens a connection with the DB using the JPA datasource details.

How do I decrypt this password before Spring Boot makes a connection with the DB with JPA's datasource

Answer 1

You need to specify the dataSource programmatically :

And in the line :

 dataSourceBuilder.password("");

Use your custom method to decrypt.

 dataSourceBuilder.password(decrypt(dbPassPropertieCrypted));
