创建配置类

package local.ateng.java.email.config;

import org.dromara.email.api.MailClient;
import org.dromara.email.comm.config.MailSmtpConfig;
import org.dromara.email.core.factory.MailFactory;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.ArrayList;
import java.util.List;

@Configuration
@ConfigurationProperties(prefix = "sms-email")
@Data
public class DefaultMailSmtpConfig {

    private String port;
    private String fromAddress;
    private String nickName;
    private String smtpServer;
    private String username;

       return MailFactory.createMailClient(key, new BlackListImpl());
    }

    /**

    public class BlackListImpl implements Blacklist {

        @Override
        public List<String> getBlacklist() {
            List<String> blacklist = new ArrayList<>();
            blacklist.add("2385569970@qq.com");
            return blacklist;
        }
    }

发送邮件

创建测试类

package local.ateng.java.email;

import org.dromara.email.api.MailClient;
import org.dromara.email.comm.entity.MailMessage;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

import java.util.ArrayList;
import java.util.List;

@SpringBootTest
public class EMailTests {
    @Autowired
    private MailClient mailClient;
}

发送邮件

@Test
public void test1() {
    List<String> mailAddress = new ArrayList<>();
    mailAddress.add("2385569970@qq.com");
    mailAddress.add("kongyu@beraising.cn");
    MailMessage message = MailMessage.Builder()
            .mailAddress (mailAddress)
            .title("测试标题")
            .body("测试邮件发送")
            .htmlContent("11111111111")
            .build();
    mailClient.send(message);
}

带附件

注意带附件（批量的，单个的不影响）的需要JDK>=11，否则会报错 java.lang.NullPointerException: Deflater has been closed 、java.lang.NoSuchMethodError: java.nio.ByteBuffer.flip()Ljava/nio/ByteBuffer;

@Test
public void test3() {
    List<String> mailAddress = new ArrayList<>();
    mailAddress.add("2385569970@qq.com");
    mailAddress.add("kongyu@beraising.cn");
    HashMap<String, String> filesMap = new HashMap<>();
    filesMap.put("sms4j.png", "https://sms4j.com/logo.png");
    filesMap.put("sa-token.png", "https://oss.dev33.cn/sa-token/doc/home/sa-token-jss--tran.png");
    MailMessage message = MailMessage.Builder()
            .mailAddress(mailAddress)
            .title("测试标题")
            .body("测试邮件发送")
            .htmlContent("11111111111")
            .files(filesMap)
            .zipName("附件-归档.zip")
            .build();

    mailClient.send(message);

}
