Spring Cloud Config Client with 4.0.1 with Jasypt 3.0.5 does not decrypt the credentials for the Spring Cloud Config Server on startup

[saurabhsule82]

I'm trying to using Jasypt 3.0.5 in our Spring Cloud Config Client based on 4.0.1 release (Spring 6.0.5 release) so that I can encrypt the credentials for the Spring Cloud Config Server in the client's application.properties file. I've written the client based on the examples provided and I see that the credentials are not decrypted when the client is executed. As a result the connection fails. I'm unable to find a way where the credentials are decrypted before they are used by the client to make a connection to the config server. Encrypting any other custom property in the application.properties works well.

Here is my sample code:

//////////////////////////

import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.CommandLineRunner; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.core.env.Environment;

import com.ulisesbocchio.jasyptspringboot.annotation.EnableEncryptableProperties;

@SpringBootApplication @EnableEncryptableProperties public class ConfigServerSampleClient implements CommandLineRunner {

@Autowired
private Environment env;

public static void main(String[] args) throws Exception {
    SpringApplication.run(ConfigServerSampleClient.class, args);
}

}

//////////////////////

Here is my application.properties file:

spring.profiles.active=test

spring.application.name=config-client

spring.config.import=configserver:https://localhost:8443/config-server/

spring.cloud.config.username=ENC(ESbGS75MjvgICT/bPDwk/vTo2ZBVTnqQkpyoGNP/WohJobV653/UswcirTRVP5aQ)

spring.cloud.config.password=ENC(oCirYOlGhC9yQRVLe+WXGfPvRokLH5t/12182FmtAuHvcLNIwA3JEprsUBUYlEcL)

Any help is really appreciated.

I resolved the issue. Here is what I had to do to implement Jasypt encryption in Spring Cloud Config Client which basically is a Spring Boot Application that acts as client for Spring Cloud Config Server:

1. Inside my pom.xml, I had to import following dependencies:

   org.springframework.cloud spring-cloud-starter-config

   <dependency>
       <groupId>org.springframework.cloud</groupId>
       <artifactId>spring-cloud-starter-bootstrap</artifactId>
   </dependency>
   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-web</artifactId>
   </dependency>
   <dependency>
       <groupId>com.github.ulisesbocchio</groupId>
       <artifactId>jasypt-spring-boot-starter</artifactId>
       <version>3.0.5</version>
   </dependency>
   <dependency>
       <groupId>com.github.ulisesbocchio</groupId>
       <artifactId>jasypt-spring-boot</artifactId>
       <version>3.0.5</version>
   </dependency>

2. In my main class, I made two changes: Earlier (not working): @SpringBootApplication @@EnableEncryptableProperties public class ConfigServerSampleClient implements CommandLineRunner { public static void main(String[] args) throws Exception { SpringApplication.run(ConfigServerSampleClient.class, args); } } Now (working): @SpringBootApplication public class ConfigServerSampleClient implements CommandLineRunner { public static void main(String[] args) throws Exception { new SpringApplicationBuilder() .environment(new StandardEncryptableEnvironment()) .sources(ConfigServerSampleClient.class).run(args); } }
