MailApplicationTests(测试类)

package com.springbootemaildemo;

import com.springbootemaildemo.excel.c.StudentService;
import com.springbootemaildemo.send.SendHtml;
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.test.context.junit4.SpringRunner;
import org.springframework.util.ResourceUtils;
import com.springbootemaildemo.service.MailService;

import java.io.File;
import java.io.FileNotFoundException;
import java.util.HashMap;
import java.util.Map;

@RunWith(SpringRunner.class)
@SpringBootTest
public class MailApplicationTests {

    @Autowired
    SendHtml sendHtml;

    /**
     * 测试发送html邮件
     */
    @Test
    public void sendHtmlMessage() {

String sc = "<html>
" +
        "<body>
" +
        "<p id="mailUuid" style="display: none">" + bodys + "</p>
" +
        "<p id="uuid" style="">" + bodys2 + "</p>
" +
        "<p>CDE</p>
" +
        "</body>
" +
        "</html>";

        sendHtml.sendHtmlMail("邮件测试", sc);
    }

}

html文件：

<!DOCTYPE html>
<html>
<body>
<p id="mailUuid" style="display: none">ABC</p>
<p id="uuid" style="">ABCDDDD</p>
<p>CDE</p>
