Mail test application

This application is used for test if java can send email in local server.

Usage

Three options:

Set configuration in application.yml

Edit the application.yml file before build the application. Set the correct info in spring.mail section (see https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-email.html)

After build use with the correct profile and an email:

java -Dspring.profiles.active=production -jar target/mail-test-0.0.1-SNAPSHOT.jar "email@email.com"

or with extra params:

java -Dspring.profiles.active=production -jar target/mail-test-0.0.1-SNAPSHOT.jar "email@email.com" "subject" "message"

Set configuration in application.yml with encrypted info

If you need crypt info (like the password), you can crypt any configuration key in application.yml with jaspyt framework.

Firts, you need crypt the key_value:

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

Use a custom password and don't storage in 'application.yml'

Sample output:

# java -cp jasypt-1.9.2.jar org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI jasypt-1.9.2.jar org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI input="a key value" password="custom-password" algorithm=PBEWithMD5AndDES

----ENVIRONMENT-----------------

Runtime: Oracle Corporation Java HotSpot(TM) 64-Bit Server VM 25.162-b12



----ARGUMENTS-------------------

algorithm: PBEWithMD5AndDES
input: a key value
password: custom-password



----OUTPUT----------------------

VnS9Hrbh5KlmqZXeW9E2A1Y9JCh3F0YM

Use the output with ENC command, like:

spring:
    mail:
        password: ENC(VnS9Hrbh5KlmqZXeW9E2A1Y9JCh3F0YM)

After build the app, you cant usage with jasypt.encryptor.password enviroment property:

java -Dspring.profiles.active=development -Djasypt.encryptor.password="custom-password"  -jar target/mail-test-0.0.1-SNAPSHOT.jar "email@email.com"
