SpringBoot 项目发邮件

SpringBoot 项目发邮件

1、建立项目springboot项目

<!-- pom.xml 文件添加starter mail依赖 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

项目pom.xml内容如下

<?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>2.7.1</version>
        <relativePath/> 
    </parent>
    <groupId>org.example</groupId>
    <artifactId>sbootmail</artifactId>
    <version>1.0-SNAPSHOT</version>

    <properties>
        <maven.compiler.source>17</maven.compiler.source>
        <maven.compiler.target>17</maven.compiler.target>
        <java.version>17</java.version>
    </properties>

    <dependencies>
        <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>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <version>2.7.1</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

2、 建立项目配置文件yml

src/main/resources/application.yml

spring:
  mail:
    default-encoding: utf-8
    host: smtp.126.com
    username: webrx@126.com
    #此处为邮件服务器的授权码，不是密码
    password: XQUJQKBFBYWRFBKS

3、编写主入口程序

src/main/java/cn/webrx/App.java

package cn.webrx;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class,args);
    }
}

4、编写测试程序

src/test/java/cn/webrx/SendMail.java

package cn.webrx;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringBootVersion;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;

@SpringBootTest
public class SendMail {
    @Autowired
    JavaMailSender sender;

    @Test
    void send() {
        SimpleMailMessage smm = new SimpleMailMessage();
        smm.setTo("7031633@qq.com");
        smm.setSubject("主题");
        smm.setText("正文");
        smm.setFrom("webrx@126.com");
        sender.send(smm);
    }

    @Test
    void test() {
        System.out.println("hello ");
        System.out.println(SpringBootVersion.getVersion());
    }
}

执行SendMail类的send()方法，测试通过。
