Action:
Consider defining a bean of type 'org.springframework.mail.javamail.JavaMailSender' in your configuration.
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.messaging.Message;
import org.springframework.messaging.MessagingException;

Answer 1

you've to provide the mail configuration in application.properties
spring.mail.host=MAIL_SERVER_IP
spring.mail.port=MAIL_SERVER_PORT
spring.mail.userName=USER_NAME
spring.mail.password=THE_PASSWORD
and if authentication not enable in server then
remove userName and password and add this
spring.mail.properties.mail.smtp.auth=false
spring.mail.properties.mail.smtp.starttls.enable=false

Answer 2

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.JavaMailSenderImpl;
#Configuration
public class Config {
#Bean
public JavaMailSender javaMailSender() {
return new JavaMailSenderImpl();
}
}
You can also return an instance of JavaMailSenderImpl() from your #Bean above saving you the hustle of having to implement a bunch of methods when you try to return the actual JavaMailSender() class.

Answer 3

Declare a #Bean of the type JavaMailSender in a Configuration class (This is useful when you want to inject a class which is not part of your Spring Context, like a class that belongs to a 3rd-party lib, which happens to be your case). For example:
#Configuration
public class MyConfig {
#Bean
public JavaMailSender javaMailSender() {
return new JavaMailSender();
}
}
Make sure that the you have set the right properties under application.properties as well.
Also, take a look into this question, as I believe this is a duplicate (if it's not, I am sorry)

Answer 4

In My project i was reading email properties file like hostname, port etc from spring config server (Spring cloud).
I was missing a dependency at client end. Once i added that Dependency.
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
JavamailSender class able to read those properties and worked fine.
In spring boot we need not define JavaMailSender bean manually. spring boot does itself.

Answer 5

the best answer I ve found was to check if you have a type in your application.properties:
spring.mail.host
spring.mail.username
spring.mail.password
spring.mail.port

I have this error and it was related to missing properties in application.yml in the test folder.
