SpringMVC发送电子邮件

Question

I'm trying to send email using SpringMVC. I've made a bean JavaMailSender and get an error.

@Bean
public JavaMailSender javaMailSender(){
  JavaMailSenderImpl javaMailSender = new JavaMailSenderImpl();
  javaMailSender.setUsername("test");
  javaMailSender.setPassword("test");
  javaMailSender.setPort(56);
  javaMailSender.setHost("smtp.test.ru");
  return javaMailSender;
}

Error:

04-Dec-2016 20:05:50.699 SEVERE [RMI TCP Connection(31)-127.0.0.1] org.springframework.web.context.ContextLoader.initWebApplicationContext Context initialization failed java.lang.NoClassDefFoundError: org/springframework/mail/javamail/JavaMailSender

My context with this bean:

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.JavaMailSenderImpl;

import java.util.Properties;

@Configuration
@PropertySource("classpath:util.properties")
@PropertySource(value = {"classpath:auth.properties"})
public class MailContext {
    @Bean
    public JavaMailSender javaMailSender(){
        JavaMailSenderImpl javaMailSender = new JavaMailSenderImpl();
        javaMailSender.setUsername("test");
        javaMailSender.setPassword("test");
        javaMailSender.setPort(556);
        javaMailSender.setHost("test.ru");
        javaMailSender.setProtocol("smtp");
        Properties properties = new Properties();
        properties.setProperty("mail.debug", "true");
        javaMailSender.setJavaMailProperties(properties);

        return javaMailSender;
    }
}

My pom :

...
<dependency>
  <groupId>com.sun.mail</groupId>
  <artifactId>javax.mail</artifactId>
  <version>1.5.5</version>
</dependency>
<dependency>
  <groupId>javax.activation</groupId>

<dependency>

What did I do wrong?

Answer 1

It appears that you need, but do not have spring-context-support-4.3.4.RELEASE.jar on your classpath.

To add this to your application's classpath in IntelliJ, edit your project's Project Structure , and add a Library under Libraries referencing the Spring jar file. Add or edit your Module and add the library to the Module . Add or edit Artifacts and make sure the library or module is one of the Available Elements for the Artifact .

Under the Run menu, click Edit Configurations for your Tomcat configuration, on the Deployment tab, add the artifact (or library) to the Deploy at server startup list.

This information at JetBrains provides more information on configuring your Intellij setup to get desired jars on your classpath.

It is also possible that you need to make a simple configuration change to your dependency in your pom.xml:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context-support</artifactId>
    <version>4.3.4.RELEASE</version>
    <scope>runtime</scope>
</dependency>

(NOTE the addition of the <scope> element. More information on Maven scopes available here .)

(These instructions may vary depending on the version of Intellij that you are using.)

In summary, you need to get the Spring jar on your application's classpath at runtime.
