Spring:
  #邮箱地址配置
  mail:
    host: 邮箱服务器地址
    port: 邮箱服务器端口
    username: 邮箱服务器用户名
    password: 邮箱服务器密码
    #编码格式
    default-encoding: utf-8
  #freemarker默认存放路径
  freemarker:
    template-loader-path: classpath:/templates

测试类代码 ：

@SpringBootTest
public class FreeMarkerTest {

// 自动注入FreeMarker配置类,用户获取模板
@Autowired
private Configuration configuration;

// 注入Spring发送邮件的工具类
@Autowired
private JavaMailSender sender;

@Test
@DisplayName("测试邮件模板")
public void testMailFreeMark() throws Exception{
	//初始化数据
    List> rows = new ArrayList<>();
    Map map = new HashMap<>();
    map.put("id","1");
    map.put("name","张三");
    map.put("expirydate","2021-04-21");
    map.put("surplus","61");
    Map map2 = new HashMap<>();
    map2.put("id","31400000024");
    map2.put("name","李四");
    map2.put("expirydate","2021-04-22");
    map2.put("surplus","2");
    rows.add(map);rows.add(map2);
    // 定义个数据根节点
    Map root = new HashMap<>();
    root.put("username","zhangsan");
    root.put("rows",rows);
    //获取test.ftl模板
	Template template = configuration.getTemplate("test.ftl");
	//获取模板内容
    String s = FreeMarkerTemplateUtils.processTemplateIntoString(template, root);
    System.out.println("--->"+s);
    MimeMessage mimeMessage = sender.createMimeMessage();
    //设置邮件重要性级别
    mimeMessage.setHeader("importance","High");
    MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true, "UTF-8");
    helper.setFrom("service@chinahuanong.com.cn","personalTest");
	//发送给谁
    helper.setTo("XXX@163.com");
	//邮件标题
    helper.setSubject("FreeMarker测试");
    helper.setText(s,true);
    sender.send(mimeMessage);//发送
}
