相信使用過Spring的衆多開發者都知道Spring提供了很是好用的JavaMailSender接口實現郵件發送。在Spring Boot的Starter模塊中也爲此提供了自動化配置。下面經過實例看看如何在Spring Boot中使用JavaMailSender發送郵件。html

快速入門

在Spring Boot的工程中的pom.xml中引入spring-boot-starter-mail依賴：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.1.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.ctf</groupId>
    <artifactId>project</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>project</name>
    <description>Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.3.2</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>
    </dependencies>
</project>

如其餘自動化配置模塊同樣，在完成了依賴引入以後，只須要在application.properties中配置相應的屬性內容。java

下面咱們以QQ郵箱爲例，在application.properties中加入以下配置（注意替換本身的用戶名和密碼）：spring

spring.mail.host=smtp.qq.com
spring.mail.username=QQ郵箱地址
spring.mail.password=QQ郵箱的受權碼
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true

若是不是用QQ郵箱作郵箱服務器的話，請參考相關郵箱服務的相關說明。apache

這裏給出QQ郵箱的相關說明：https://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=1001256服務器

經過單元測試來實現一封簡單郵件的發送：

package com.ctf.project;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import javax.mail.internet.MimeMessage;

/**
 * @author: Tu9ohost
 */
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest
public class sendInlineMail {
    @Autowired
    private JavaMailSender mailSender;

    @Test
    public void sendAttachmentsMail() throws Exception{
        MimeMessage mimeMessage = mailSender.createMimeMessage();

        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage,true);
        helper.setFrom("liuyu1199633@qq.com");
        helper.setTo("tugohost@gmail.com");
        helper.setSubject("主題：嵌入靜態資源");
        helper.setText("<html><body>Hello,World</body></html>",true);
/*
        FileSystemResource fileSystemResource = new FileSystemResource(new File("weixin.jpg"));
        helper.addInline("weixin",fileSystemResource);*/

        mailSender.send(mimeMessage);
    }
}
